Silence Is Not Consent: A Framework for Posthumous AI Governance
Digital Dignity Institute Research Team
Abstract
This paper advances a governance framework for AI-generated replicas of deceased individuals, arguing that the absence of explicit consent cannot be interpreted as permission to recreate, commercialize, or deploy a person's digital likeness after death. We propose a tiered consent architecture spanning pre-mortem planning, estate authority, and platform accountability.
The Problem of Posthumous Consent
The rapid proliferation of AI systems capable of generating convincing replicas of deceased individuals — their voices, likenesses, written styles, and conversational patterns — has outpaced the development of any coherent governance framework. Existing legal instruments, designed for a world in which the dead could not speak, offer inadequate protection against the commercial and personal exploitation of digital remains. This paper argues that the foundational error in current approaches is the treatment of silence as consent: the assumption that because a person did not explicitly prohibit posthumous AI replication, such replication is permissible.
A Tiered Consent Architecture
We propose a tiered consent architecture that distributes authority across three temporal stages. In the pre-mortem stage, individuals should have access to standardised instruments — analogous to advance healthcare directives — through which they can specify their preferences for posthumous AI use of their likeness, voice, and personal data. In the post-mortem stage, estate authority should be clearly defined, with default rules that err toward restriction rather than permission. At the platform level, operators of AI systems capable of generating posthumous replicas should bear affirmative obligations to verify consent before deployment, regardless of whether the individual or their estate has taken proactive steps.
Regulatory Landscape and Gaps
Current regulatory frameworks address posthumous AI replication only incidentally, through instruments designed for other purposes: right of publicity statutes, data protection regimes, and intellectual property law. None of these frameworks adequately addresses the distinctive harms of posthumous AI replication — the violation of the deceased's expressed or reasonably inferred preferences, the distress caused to surviving family members, and the broader social harm of a world in which the dead can be made to speak. We survey the regulatory landscape across twelve jurisdictions and identify the minimum elements of an adequate governance framework.
Platform Accountability and Enforcement
The paper concludes with a set of recommendations for platform operators, legislators, and international bodies. For platforms, we propose a duty of inquiry — an obligation to take reasonable steps to determine whether consent exists before deploying posthumous AI replicas — and a default prohibition on commercial use absent explicit pre-mortem authorisation. For legislators, we propose model statutory language for posthumous AI consent instruments and default rules. For international bodies, we propose a coordination mechanism to address the cross-border dimension of posthumous AI replication, which current jurisdictional frameworks cannot adequately address.
Key Findings
- 01
Silence cannot be treated as consent to posthumous AI replication under any defensible ethical or legal framework.
- 02
Existing legal instruments — right of publicity, data protection, IP law — are structurally inadequate for posthumous AI governance.
- 03
A tiered consent architecture spanning pre-mortem planning, estate authority, and platform accountability is the minimum adequate response.
- 04
Platform operators should bear affirmative obligations to verify consent, not merely to respond to complaints.
- 05
International coordination is essential: posthumous AI replication is inherently cross-border and current jurisdictional frameworks cannot address it.
Methodology
Doctrinal legal analysis across twelve jurisdictions; comparative regulatory survey; structured interviews with estate attorneys, platform policy teams, and bereaved family members; ethical framework analysis drawing on autonomy theory, dignity theory, and relational ethics.
