Best Ghostwriting Companies in Australia: How to Choose the Right One
If you have a book inside you, and you know you are not going to find the time or craft to write it yourself, the next question lands fast. Which ghostwriting company in Australia should you actually trust with the whole thing? Not the one with the loudest ad spend, but the one that is right for your book, your voice, your deadline, and your budget.
This guide is written for Australian authors and writers at that decision point. It walks through what a ghostwriter actually does, how a real project runs from first call to finished manuscript, the criteria that matter when you compare companies, and a shortlist of ten names that come up most often. It also covers what most roundup articles skip: Australian copyright and moral rights, the practical red flags in a quote, and the free local resources you can lean on before signing.
Nothing here is dressed up. The focus is on helping you make a confident choice, not on selling you a service.
What Does a Ghostwriter Actually Do for an Australian Author?
A ghostwriter is a professional writer you hire to draft a book that will be published under your name. They handle the heavy lifting, which usually means structure, interviews, chapters, and revisions, while you keep ownership and the final say over every important decision. In Australia, authors hire ghostwriters most often for memoirs, business and leadership books, "as told to" biographies, and fiction where the author has a strong story idea but limited writing craft or writing time.
The role is different from an editor, and it is different from a co-author. An editor takes the words you have already written and makes them sharper. A co-author shares the writing load and shares the public credit on the cover. A ghostwriter writes, you own, and credit is a separate decision agreed up front in the contract.
That last point matters more than most authors realise. In Australia, you do not automatically own the copyright of a book just because you paid for it. Ownership transfers through a written assignment in the contract, which is why reading the agreement with real care is non-negotiable. We will come back to this in the copyright section.
Most Australian authors who go looking for a ghostwriter land on one of a handful of use cases. A business owner who wants a leadership book out before a big conference. A grandparent who wants a family memoir written while there is still time to interview the people in it. A novelist who has the plot and characters but struggles to sit down and produce a hundred thousand words. A public figure recording a life story. Each needs a slightly different kind of ghostwriter, a point we return to further down.
How Does a Ghostwriting Project Typically Run from First Call to Finished Manuscript?
A real ghostwriting project runs through five visible stages. A discovery call, a written agreement with an outline, interviews and research, staged chapter drafts, and a final manuscript. Most book length projects take several months, and a good company will tell you up front where your project sits on that spectrum.
The discovery call is a free conversation. The company asks about your book, your goals, your timeline, your genre and the shape of your budget. You ask about their process, who the actual writer will be, how they handle Australian voice, and what their revision policy looks like. Nobody signs anything at this stage. If a company is pressing you to commit on the first call, that is already useful information about how they operate.
The written agreement and outline come next. A legitimate agreement covers scope, timeline, payment schedule, number of revision rounds, confidentiality, copyright assignment and credit. Alongside the agreement you receive a chapter by chapter outline that you sign off on before any chapters are written. Think of the outline as the blueprint. It is far cheaper to move a wall on a blueprint than to move it after the house is built.
Interviews and research are where your voice gets captured. For memoir and non fiction, this usually looks like a series of recorded conversations across several weeks, often two to four hours at a time, with the ghostwriter transcribing and following up by email in between. For business books, it might include access to your talks, articles and internal materials. For fiction, interviews are often replaced or supplemented by structural planning sessions around plot, characters and world. The quality of your finished book has more to do with the quality of these sessions than almost anything else.
Staged drafting is where chapters start to arrive, usually in batches of two or three. This is deliberate. Delivering the whole book at the end, with no feedback along the way, is how projects go off the rails. Staged delivery lets you catch voice issues, structural problems or factual gaps while there is still time to fix them without a full rewrite.
Revisions and the final manuscript close out the project. The number of included revision rounds is usually written into the agreement, and so is what happens if you need more. By the end of this stage you have a manuscript that is ready to move into editing and formatting. If you want to understand the next layer of work, our book editing services in Victoria page explains what editors do after the ghostwriter is finished.
If a company cannot describe stages like these to you on a first call, that is a very loud signal that the process is not really there.
What Should Australian Authors Look For in a Ghostwriting Company?
The criteria that actually matter are not the ones that get splashed across homepages. They are a demonstrated ability with Australian voice, a named writer you can research, a clear voice capture method, a stated revision policy, strict confidentiality, Australian standard rights handling, and a sensible communication cadence. Company size and marketing spend sit much lower on the list than most authors assume.
Australian presence or voice capability
Where the office is matters less than whether the writer can convincingly handle Australian idiom, setting, humour and references. A Melbourne-based writer working on a Melbourne memoir is one strong fit. An offshore writer with a proven track record of Australian clients is another. What matters is the fit, not the postcode. The question to ask directly is where the actual writer is based, how many Australian books they have worked on, and how they handle voice if they are not local.
If your book is set in Australia and reads for Australian readers first, you need a writer who knows a milk bar from a corner store, who gets why a Hills hoist in a backyard scene lands differently than a clothesline, and who will not give your Sydney narrator a Boston accent in dialogue. Small details, and they add up fast.
A named writer, not a brand
Before you sign anything, ask who is actually going to write your book. A legitimate company will tell you and share that writer's previous samples with you. A company that will not name the writer, or who hints that a "team" will handle it, is selling you an invisible process. You cannot evaluate someone you cannot see.
Voice capture method
Ask how they capture your voice. Good answers include recorded interviews with structured prompts, written questionnaires, short early samples where you provide text in your own words for the ghostwriter to study, and early voice checks after the first chapter. "We just know how to write like you" is not a method. It is a slogan.
Think about character voice the same way a novelist does. A thoughtful ghostwriter builds a short reference sheet on how you speak, what metaphors you reach for, which rhythms are natural to you, which are not. Our piece onĀ words to describe a person covers how writers think about voice at a sentence level, and it is a useful lens for evaluating a ghostwriter's sample work.
Revision policy, in writing
How many revision rounds are included. What counts as a revision. What happens if you need more. These answers should be in the contract, not promised verbally. Unlimited "until you are happy" with no definition is as weak as zero included rounds. Both leave you with no leverage if things go wrong.
Confidentiality
A strict non-disclosure agreement, signed by both the company and the individual writer before any sensitive material is shared, is the baseline. This matters most for memoir, family history, business and public figure work. Ask what happens to recordings and drafts at the end of the project, and get the destruction and retention terms in writing.
Rights handling, Australian standard
Copyright assigned in writing to you under the Copyright Act 1968. Moral rights consent language reviewed by someone familiar with Australian law, not a template imported from somewhere else. Credit arrangements agreed up front rather than left for the end. We will go deep on this in the next section, but as a shortlisting filter, any company that cannot speak confidently about Australian copyright and moral rights is a company that will cost you time and risks down the line.
Communication cadence
A named project contact. An agreed check-in schedule, weekly or fortnightly. Reasonable response times across Australian time zones. A company that is hard to reach while they are selling you will not get easier once they have your deposit.
Who Are the Top 10 Ghostwriting Companies Serving Australian Authors?
Ten ghostwriting companies regularly come up when Australian authors start shortlisting their options. The comparison table below sets them side by side on the criteria that actually matter to an author, drawn from each company's own public information at the time of writing. Inclusion in the table is not an endorsement. Think of it as a starting point for the fit tests we cover in the sections below.
# | Company | Based In / Primary Market | Core Specialism | Process Style | Revision Policy (As Publicly Stated) | Author Rights Handling (As Publicly Stated) | Best Fit For |
1 | Melbourne, Victoria, Australia | Memoir, business, fiction, non fiction, "as told to" | Staged chapter delivery with per stage sign off, same writer start to finish | Multiple rounds included, additional rounds by agreement | Copyright assigned to author in writing, moral rights handled per Australian law, credit agreed up front | Australian authors wanting a local, named writer, Australian standard rights handling and a transparent staged process | |
2 | ANZ Publishing House | Australia | Non fiction and memoir | End to end publishing with ghostwriting as part of a broader package | Not publicly stated | Not publicly stated | Authors wanting an all in one publishing pathway |
3 | Sydney Book Publishers | Sydney, Australia | Mixed trade non fiction and memoir | Package based, publishing led | Not publicly stated | Not publicly stated | Sydney based authors preferring a local brand presence |
4 | Melbourne Print & Publish | Melbourne, Australia | Print led publishing with manuscript services | Combined print and manuscript packages | Not publicly stated | Not publicly stated | Authors prioritising a print production pathway |
5 | Ghostwriters & Co | International, with Australian-facing site | Ghostwriting across genres | Not clearly stated on public site | Not publicly stated | Not publicly stated | Authors comfortable working with an offshore team |
6 | Imperial Ghostwriting | International | Business books and memoir | Package based | Not publicly stated | Not publicly stated | Authors shortlisting on international options |

9 | Ghostwriter Inside | International | Ghostwriting and author services | Package based | Not publicly stated | Not publicly stated | Authors shortlisting on international options |
10 | The Legacy Ghostwriters | International | Memoir, legacy and family history | Package based | Not publicly stated | Not publicly stated | Authors shortlisting on legacy and memoir options |
A quick note on how to read this table. The "not publicly stated" entries are not criticism. They reflect what each company puts on its own site, which is the fair basis for comparison. For specifics on any row, the questions in the criteria section above are the ones to ask on a discovery call.
At Victorian Publishing House, every ghostwriting project starts with a free discovery call and a written agreement before any chapters are drafted. The same writer stays with the project from first interview to final manuscript, which keeps your voice consistent instead of handing you off between unfamiliar people halfway through. Chapters are delivered in staged batches, so you catch any issues early, revisions are included and defined in writing, and your copyright and moral rights are handled in line with Australian law.
What Do Australian Authors Need to Know About Copyright, Moral Rights and Credit?
Under Australian law, a ghostwriter is the first owner of the copyright in the words they write. That ownership transfers to you only through a written assignment in the contract. Moral rights (attribution, against false attribution, and integrity) belong to the ghostwriter personally and cannot be assigned to you, only consented to for specified acts. Credit on the cover, ghost or co-author or "as told to", is a separate commercial decision you settle in the contract before writing begins. These three points are the ones most roundup articles skip, and they are the ones that cost authors the most when the contract is wrong.
Copyright assignment
The Copyright Act 1968 is the governing legislation. In practice, when a ghostwriter writes your manuscript, they are the author of those words in copyright terms. Without a written assignment clause, they keep ownership even though you paid for the work. This is why a one-line "all rights are yours" promise in an email does not do the job. The assignment needs to be in the written agreement, dated and signed by both sides, and it needs to cover the actual categories of use you care about, such as print, ebook, audio, foreign editions and screen adaptations.
Moral rights
Moral rights are a separate layer that came in with the Copyright Amendment (Moral Rights) Act 2000. They give an author three personal rights: to be attributed as the author of the work, not to have the work falsely attributed to someone else, and to have the integrity of the work protected against treatment that would prejudice the author's honour or reputation. These rights attach to the person who actually wrote the words, which in a ghostwriting arrangement is the ghostwriter, not you.
You cannot have moral rights assigned to you. What you can have is written consent to specified acts that would otherwise breach those rights, which is what makes a ghost credit legally safe. A clause claiming to "waive all moral rights" is not Australian standard language. If you see it in a contract, that is a sign the template has been imported from a jurisdiction that works differently, and it is worth asking the company to rewrite the clause in line with Australian law.
Credit (ghost, co author, "as told to")
Credit is not a legal question so much as a commercial one, but it is worth settling before writing starts, not after. The three common options are a straight ghost credit, where the writer's name does not appear anywhere, a co author credit, where both names sit on the cover, and an "as told to" credit, where you remain the named author on the cover and the writer is acknowledged inside the book.
Each option has consequences. A ghost credit gives you full public ownership of the book but ties the writer's reputation only to internal references. A co author credit shares the public identity of the book, which has implications for future books in your name. An "as told to" credit is often the natural compromise for memoir and biography, giving the subject the cover and the writer an acknowledged role.
Think about what your next book, or your author brand more broadly, needs to look like. If you plan to build out a public author presence after this book, the credit decision also shapes the shape of yourĀ author website and the way you talk about the book in interviews.
Confidentiality
Confidentiality sits alongside copyright and moral rights as the third plank of a solid ghostwriting contract. The agreement should state the scope of confidential information, the duration of the obligation, who signs it (the company and the individual writer, not just the company), what happens to interview recordings and drafts at project end, and what counts as a breach. If any of this is thin or generic, raise it before signing. Our writing on the role of a motif in a book is unrelated to law but is a useful reminder that recurring themes in your life story are often the most sensitive to protect.
How Do You Spot a Ghostwriting Pitch That Is Not Worth Taking?
A ghostwriting pitch is worth questioning if it guarantees bestseller status, refuses to name the actual writer, bundles a lump sum with no breakdown, offers no written revision rounds, pushes for most of the payment up front, uses vague "lifetime rights" language without clearly assigning copyright, leans heavily on template testimonials with no verifiable client or title, or pressures you to sign on a time limited "discount today only". Any one of these in isolation is a question to raise. Two or more at once is a strong signal to walk away.
Guaranteed bestseller or guaranteed sales. No legitimate company can promise reader behaviour. Marketing can influence it, writing quality can support it, but nobody can guarantee what readers will buy once your book is live. If a pitch opens with a sales guarantee, treat the rest of it with scepticism.
No named writer. A pitch that will not tell you who will write the book is a pitch for an invisible team. You cannot evaluate samples from someone you cannot name, and you cannot build a working relationship with a brand.
No itemised scope. A single bundled figure covering "everything" gives you no basis to compare quotes or hold anyone to a specific deliverable. Ask for an itemised breakdown that separates writing time, interview time, revision rounds, editing, and any add-ons like formatting or launch support.
No written revision rounds. Revisions are where fit between you and the writer actually gets tested, and they are the mechanism that lets you steer the book without starting a dispute. If revisions are vague, that is where things will break later.
Pressure to pay most of the fee up front. A staged payment schedule tied to deliverables, usually something like 20 to 40 per cent at signing with the balance across outline, chapters, and final manuscript, is normal and reasonable. One lump sum before any work is produced is a flag.
Vague "lifetime rights" language. Beware clauses that promise "lifetime rights" or "unlimited use" without specifically assigning copyright to you. These phrases can be read in ways that let the company keep rights you thought you were buying.
Template testimonials. Reviews that could apply to any ghostwriter, with no verifiable client, book title, or year, are worth less than you think. Ask for one or two references you can actually contact.
Pressure to sign today. "Discount expires tonight" is sales theatre, not a professional process. A real agency expects you to think, consult a solicitor if you want to, and sign on your own timeline.
Ambiguity on GST. If a quote is not clear whether it is GST inclusive, ask directly. In Australia, professional services supplied by a GST registered business usually carry GST, and quoting ambiguously is a soft flag about the rest of the paperwork.
Where Can Australian Authors Get Independent Advice Before Signing?
Before committing to any ghostwriting company, Australian authors should take time to review the agreement, understand the scope of work, and make sure the contract clearly covers copyright, confidentiality, revisions, payment terms and authorship credit.
Independent guidance can help authors understand what a professional ghostwriting agreement should contain and what questions to ask before signing. This may include general information on Australian copyright law, moral rights, publishing contracts, manuscript services and standard industry practices.
When reviewing a ghostwriting agreement, pay particular attention to who owns the copyright, how revisions are handled, what happens to interview recordings and draft material, whether confidentiality obligations are clearly defined, and how the writer will be credited. These details should be agreed in writing before substantial work begins.
Authors should also compare the written agreement with the promises made during the initial consultation. Timelines, deliverables, communication arrangements, payment stages, and revision policies should all be clearly documented so there is less room for confusion later in the project.
For higher value or more complex agreements, authors may also choose to seek independent professional advice before signing. The aim is not to make the process complicated, but to make sure the responsibilities of both the author and the ghostwriting company are clear from the beginning.
If part of what you are weighing is whether to go pure self-publishing, hybrid or traditional, our guide toĀ what is hybrid publishing in Australia walks through the trade-offs, and the best publishing houses in Australia overview covers the wider landscape of options.
How Should You Judge Whether a Ghostwriting Company Is the Right Fit for Your Book?
Judge fit on four practical tests, run in this order, before you commit to the full project fee. A sample of the actual writer's work in a similar genre, a short paid trial chapter from your own material, a direct conversation between you and that writer, and a written process document that matches the sales pitch line for line. If a company resists any of these, that is itself an answer.
Writer samples. Not the company's showreel or the aggregate client list, but the specific writer's previous work in a similar genre or voice. If your book is a Melbourne memoir, you want to see memoir samples, not business books. Read for voice, pacing, dialogue, and whether the writing feels like something a reader would want to sit with for several hundred pages.
Paid trial chapter. This is the single most informative thing you can do. Scope a small piece of your own material, usually two to five thousand words, under a non-disclosure agreement, with a short brief, and pay for it as a standalone piece of work. You will learn more in that one chapter than in ten portfolio reads. Companies that welcome paid trials are confident in their writers. Those that resist are usually hiding something.
Direct conversation with the writer. A short call with the actual writer, not just a sales contact, confirms three things fast. Chemistry, understanding of your brief, and communication style. If the first time you speak to the person writing your book is after the deposit has cleared, that is backwards.
Written process document. Ask for a short process document, one or two pages, covering timeline, revision rounds, payment schedule, confidentiality terms, rights, credit and communication cadence. Then check it line by line against what the sales conversation promised. Mismatches are not usually malicious. They are usually a sign that the sales side and the delivery side are not well connected, which is itself worth knowing.
If you are scoping a trial chapter around a specific craft challenge, our pieces onĀ how to write a short story andĀ how to outline a novel are useful references for what strong structural writing looks like, especially for fiction authors testing a writer on plot and pacing.
A good company welcomes these tests. One that resists them is answering the question for you.
Fiction, Memoir, Business and Beyond: Which Kind of Ghostwriter Does Your Book Need?
Fiction, memoir, business and "as told to" biographies each need a different mix of ghostwriting skills, and most companies are stronger in one or two of these areas than across all of them. Picking a specialist in your genre matters more than picking the biggest company overall.
Memoir and life story. Needs a strong interviewer, a patient listener, and a structural writer who can turn years of a life into a readable arc. The best memoir ghostwriters shape raw interview material into chapters that read like a novel, not a transcript. Family memoirs often add extra sensitivities, with living relatives who have views on how they are portrayed.
Business and thought leadership. Needs comfort with technical content, frameworks and research, and clear thinking under corporate time pressure. The best business ghostwriters can simplify an idea without flattening it, and they can produce a chapter that respects the reader's time without losing the author's depth.
Fiction. A different skill set from non fiction ghostwriting entirely. Fiction needs structural craft, dialogue, character arcs, genre expectations and world building. A ghostwriter who is excellent at memoir may be weak at plotting a thriller, and the reverse. Ask directly how many novels in your genre the writer has worked on.
"As told to" biographies. Needs the ability to balance faithfulness to the subject's voice with narrative shape, often with family and legal sensitivities layered on top. These projects frequently include archival research, old photographs, letters and interviews with multiple family members, all of which widens the ghostwriter's role beyond pure writing.
Short form. Speeches, keynote scripts, long articles, and ghostwritten LinkedIn columns are a different scope with different pricing, and are often not what full book ghostwriting companies focus on. If this is what you need, ask directly whether the company handles short form or only full manuscripts.
The point is simple. "Top ghostwriting company" is not a single answer. It is a different answer depending on what you are writing. If your project is specifically a novel, ourĀ fiction ghostwriting services in Victoria page describes the fiction-specific process, and the non-fiction ghostwriter in Victoria page covers the non-fiction side.
What Happens After the Manuscript Is Finished?
A finished ghostwritten manuscript is the starting point of production, not the end of the project. Editing, proofreading, cover design, formatting, printing or ebook conversion, and marketing all come next. Some ghostwriting companies offer these in-house as a one-stop pathway. Others deliver the manuscript and leave you to assemble the team. Both can work. The one that works for you depends on how much project management you want to carry yourself.
Editing happens in stages. Structural edits deal with the big shape of the book, pacing, chapter order, and whether sections are earning their place. Line edits deal with how the prose reads sentence by sentence. Copy edits catch inconsistencies, repetitions, and small errors. These are usually different people from the ghostwriter.
Proofreading is the final error-catching pass, done after everything else is settled. If you want a plain English explanation of what this stage actually involves, our page on what is proofreading breaks it down, and our book proofreading services in Victoria page describes how we handle it.
Cover design is where a lot of self-published books quietly undersell themselves. A rushed cover can neutralise months of ghostwriting work. Treat it as a design decision, not a graphics task, and if you want to see how we approach it, our book cover design services in Victoria page walks through the process.
Formatting turns the final manuscript into a book interior that reads well in print and on screen. Done well, it is invisible. Done poorly, it makes a professional manuscript feel amateur. TheĀ book formatting services in Victoria page explains what good formatting actually involves.
Printing is the physical production step for print runs, whether a short run for a launch or a larger run for distribution. TheĀ book printing services in Victoria page covers the practicalities.
Launch, marketing and promotion are the last mile. A good book without a plan to reach readers often sells quietly for years when it could have sold loudly in month one. Our Victoria book marketing service is built around that reality, and aĀ book video trailer can be a useful part of the mix.
A one-stop house saves months of coordination. Piecing it together works too, but needs more author time and oversight. The right answer depends on what you want your week to look like while the book is produced.
Final Thoughts
Hiring a ghostwriter is one of the biggest decisions a first-time Australian author makes. The money is significant, the timeline is long, and the quality of the finished book shapes what the next five or ten years of your author life look like. The companies that are worth your shortlist will be happy to answer every question in this guide. The ones that are not will not.
The one habit that separates authors who get a book they are proud of from authors who regret the whole process is this: slow down at the contract stage, and run the fit tests before you commit to the full fee. Everything else- timeline, style, specifics of the chapters- is downstream of that moment.
If you want to start the conversation with a Melbourne-based team that writes in Australian voice, uses staged chapter delivery with the same writer start to finish, assigns copyright to you in writing, and handles moral rights in line with Australian law,Ā Victorian Publishing House runs a free initial consultation on every ghostwriting project. Bring your book idea, your genre, your rough timeline, and your questions. We will tell you honestly whether we are the right fit, and if we are not, we will say so.
Your book deserves a careful choice. Take the time to make it.
Frequently Asked Questions
Rather than naming a single "top" writer, Australian authors are better off working through the shortlist and criteria earlier in this guide, then running the four fit tests (writer samples, paid trial chapter, direct conversation, written process document) against two or three shortlisted companies before deciding. "Top" is almost always a function of fit with your specific book, your voice and your genre, not a single ranking that holds across every project.
The best fit is the one whose process, writer, and rights handling match your book, and the comparison table above is designed to let you line up ten common options on the criteria that matter. From there, request voice samples and a short paid trial chapter from any shortlisted company. That one step will tell you more than any roundup article can.
The ten names in the table above regularly appear on Australian author shortlists, and the criteria section explains how to pick between them in a way that reflects your actual project. Services vary a lot in the specifics, so once you have a shortlist, ask each one the same questions on a discovery call and compare the answers side by side.
Start by defining your book clearly: genre, length, audience, timeline, and whether you want a ghost, co author or "as told to" credit. Then shortlist on the criteria section of this guide, ask each shortlisted company to name the actual writer and share samples, run a paid trial chapter, and read the full contract against the Australian Society of Authors Ghostwriting Agreement Package before signing. That sequence filters out most of the pitches that would waste your time and money.
Under the Copyright Act 1968, the ghostwriter is the first owner of copyright in the words they write. A written assignment clause in the contract transfers that copyright to you. Without an assignment, you do not automatically own the manuscript even if you paid for it, so this clause is non negotiable in any Australian ghostwriting agreement.
Moral rights belong to whoever actually wrote the words, which in a ghostwriting arrangement is the ghostwriter, not you. These rights cannot be assigned, only consented to in defined circumstances, which is what makes a ghost credit legally safe. The credit you receive on the cover is a separate commercial decision, agreed in writing before the project starts.
Most full length books take between six and twelve months from signing to final manuscript, with memoir usually sitting at the shorter end and research heavy non fiction or complex fiction at the longer end. Interview availability, revision rounds and the author's own feedback speed all affect timing. If a company promises a book in a few weeks for a full length project, treat that as a flag, not a feature.
Yes, if the writer has demonstrable Australian experience or a careful voice capture method, and if your contract is reviewed against Australian law. The honest answer is that fit depends on the individual writer, not the office location. Ask directly where the writer is based, how many Australian books they have worked on, how they will handle local references and setting, and have the contract reviewed before signing. For some authors offshore is the right choice; for others, local is non negotiable. There is no universal answer.
A ghostwriter writes a book that is published under someone else's name, with no public credit on the cover. A co author writes a book alongside you and shares the cover credit. The difference is public, not legal. Both arrangements still need a written copyright assignment in your favour if you want to own the book, and both need moral rights consent language to make the credit arrangement workable under Australian law.
Yes. A non disclosure agreement signed only by the company leaves the actual person who hears your private material outside the contract. Insist that the individual writer signs the NDA directly, that it covers both drafts and interview recordings, and that it includes a destruction or return clause for materials at project end.
