An AI digital twin is a licence of your identity, so the contract matters more than the software. Before any service clones your face or voice, get five things in writing: exactly what the twin may be used for, how long the permission lasts, how you can switch it off, what happens to your recordings and the trained model when the deal ends, and how you are paid and shown the numbers. There are useful benchmarks: the US Copyright Office recommends that people license likeness rights rather than assign them, SAG-AFTRA's screen contracts require specific, separately signed consent, and California makes some vague digital replica clauses unenforceable.
This guide is for creators weighing an offer from a twin, avatar or voice-clone service, or from a manager who wants to run one for them. It covers the questions to settle before signing, not how to build a clone. For contract basics that apply to any creator deal, start with our agency contract clause checklist; this page adds what changes when the asset being licensed is you.
What you are actually handing over
A twin deal bundles four different assets. Contracts that treat them as one usually give the service more than it needs.
| Asset | Why it matters | Sensible default |
|---|---|---|
| Training material: photos, scans, video and voice recordings | Often your own copyright works, and personal data about you | You keep ownership; the service gets a narrow licence to use it for your twin only |
| The trained model or voice profile | Whoever controls it can generate new material indefinitely | Used only for your account, never reused or merged, and deleted or disabled at the end |
| Outputs: posts, clips, audio and messages | Copyright in pure AI output may be thin, so the contract has to allocate rights | A clear statement of who owns or licenses outputs, and where they may appear |
| Your name, handle and persona | Lets the twin trade on your reputation | Use limited to approved contexts, with no endorsements you have not signed off |
The outputs row links to a wider question about authorship, covered in our guide to copyright in AI-generated content. If copyright in the twin's output is weak, the contract is your main protection.
The legal backdrop, in brief
Likeness law varies widely, so these are reference points to raise with a lawyer, not rules that automatically protect you.
- US Copyright Office. Its Part 1 report on digital replicas recommends a federal law against knowingly distributing unauthorised replicas, says individuals should be able to license and monetise replica rights but not assign them outright, suggests limiting licences to a relatively short term such as five or ten years, and calls for informed consent with full disclosure of intended uses.
- Tennessee. The ELVIS Act (Public Chapter 588), in force since 1 July 2024, gives every individual a property right in their name, photograph, voice and likeness, defines voice to include a simulation, and creates liability for knowingly publishing an unauthorised voice or likeness and for distributing tools whose primary purpose is reproducing a particular person without authorisation.
- California. AB 2602 added section 927 to the Labor Code. For new performances fixed from 1 January 2025, a clause letting a replica replace work you would have done in person is unenforceable where it lacks a reasonably specific description of the intended uses and you had neither a lawyer negotiating it, with commercial terms stated clearly and conspicuously, nor union representation, subject to limited exceptions in the section.
- United Kingdom. The government's March 2026 report on copyright and AI accepts that existing protections do not cover every unconsented replica and says it will consider a new digital replica or personality right.
- Privacy regulators. The OAIC page on biometric scanning lists face and voice features as biometric information, which the Privacy Act treats as sensitive, so covered organisations generally need consent. The UK ICO's guidance on biometric data concepts explains that face or voice data processed to identify someone uniquely is special category biometric data.
- European Union. Article 50 of the AI Act, applying from 2 August 2026, requires deployers of AI that generates deep fakes, meaning realistic content resembling existing people, to disclose that it is artificially generated. A realistic twin of a real creator is likely to fit that description when shown to EU audiences, which makes labelling a contract point.
Licence clause checklist
Tick each item against the draft you have been sent. A missing item is a question to send back, not something to assume in your favour.
- Named uses. A reasonably specific description of each use: which platforms, formats and purposes, mirroring the California and SAG-AFTRA standard. Anything not listed is excluded.
- Excluded uses. A written list of what the twin may never do, such as political messages, product categories you avoid, statements about other people, or content types you do not make.
- Approval rights. Your sign-off for each new campaign or content category, with a deadline after which silence means no, not yes.
- Licence, not assignment. The document should say licence throughout, non-exclusive unless you are paid for exclusivity, and never transfer ownership of your likeness or voice.
- Fixed term. A start date, an end date and renewal only by fresh written agreement. The Copyright Office's short-term suggestion is a fair anchor for negotiation.
- Revocation. A right to suspend or end use on notice, with a short shutdown window, plus immediate suspension if the twin is used outside scope.
- After the term. What happens to content already published. The Copyright Office report suggests expiry should normally stop only new uses, so if you want old outputs taken down, the contract has to say so.
- Data and model deletion. Deletion of raw recordings, scans and the trained model at the end, with written confirmation and a list of any copies kept for legal reasons.
- No wider training. A ban on using your material to train or improve any model other than your own twin, and on sharing it with third parties.
- Security. Where your data is stored, who can access it, and notice to you within a set time if there is a breach or leak.
- Pay and reporting. The fee model in plain terms, a definition of gross and net if there is a revenue share, monthly statements by use, and a right to audit.
- Labelling. Who applies AI labels required by platforms and by laws such as the EU AI Act, and a commitment that the twin will not tell audiences it is the real you. Sponsored twin content also needs ad disclosure, covered in our AI influencer disclosure guide.
- Liability. The service answers for misuse, out-of-scope outputs and security failures; indemnities run both ways rather than only from you.
- Change of control. No transfer of the agreement or your model to a buyer or affiliate without your written consent, and a right to terminate if the company is sold.
- Death or incapacity. Whether consent ends or passes to your estate. SAG-AFTRA notes that under its screen contracts consent does not automatically end on death, so state your preference.
- Separate signature. The likeness terms in a stand-alone rider you sign or initial, not inside general terms of service.
Red-flag clauses and what to ask for instead
| Wording you may see | Why it is a problem | Counter-proposal |
|---|---|---|
| “Irrevocable, perpetual, worldwide licence in all media now known or later devised” | Works like a sale with no exit, the result the Copyright Office warns against | Fixed term, named territories and media, revocation on notice |
| “You assign all rights in your voice, likeness and model” | Transfers ownership of your identity | A licence only; you keep the underlying rights |
| “We may use your data to improve our services” | Can mean your voice trains general models used by others | Use limited to your twin; no pooling, no wider training |
| Consent given by ticking the platform's terms | Buried consent falls short of the clear, separately signed standard in SAG-AFTRA's screen contracts | A signed likeness rider that lists each use |
| “The company may create new content without further approval” | You lose control of what you appear to say | Approval by campaign or category, silence counts as refusal |
| “Revenue share of net receipts” with no definition | Deductions can shrink your share to almost nothing | Defined deductions, statements by use, audit rights |
| “We may assign this agreement to any successor or affiliate” | Your twin can be sold with the company | Your consent to any transfer; exit right on change of control |
| “We may sublicense to partners” | Unknown parties gain access to your likeness | No sublicensing without written approval of each partner |
| “We retain data as long as necessary” | No real deletion date for biometric material | Deletion within a stated period after termination, confirmed in writing |
| “Creator indemnifies the company against all claims” | You carry the risk of their misuse or security failure | Mutual indemnities tied to each side's own conduct |
Plan the off switch before you start
Revocation clauses only work if you can see where the twin is running. Before launch, ask for a live register of every account, app, chat product and partner where your twin is deployed, and a named person who can disable it. Keep copies of the original consent rider, the training files you handed over and each approval you give, because a dispute will turn on what you actually agreed. If you later find your likeness in places the register does not list, treat it as an impersonation problem; our impersonation report workflow covers documenting and reporting it.
Two common twin uses raise their own questions. Voice clones used to translate your content are covered in our guide to AI dubbing for creators, and if a manager proposes to run the twin as part of a wider service, the vetting questions in choosing an AI model management agency apply as well.
Limitations of this checklist
This is general information, not legal advice, and it reflects the sources linked above as they read on 1 October 2026. The SAG-AFTRA terms described apply to union screen productions and serve here only as a benchmark; most creator deals are not covered by them. State laws such as Tennessee's and California's apply in limited circumstances, the UK and US federal proposals are not law, and privacy duties depend on who the service is and where it operates. No clause list can stop a company that ignores its contract, so the counterpart's identity and track record matter as much as the wording. Because a twin licence can follow you for years, have a lawyer in your country read it before you sign, and ask the service to pay for that review if it wants a long term.
