Quick answerBefore an AI agent grants any account access to someone claiming to represent a deceased customer's estate, it needs a death certificate or equivalent official record, proof of the requester's legal authority such as letters testamentary or letters of administration issued by a probate court, and a hard stop that routes the case to a trained human, not the agent completing the transfer itself. This is a fundamentally different verification chain than a living customer's power of attorney, because the account holder can no longer confirm anything themselves.
This is not the same problem as a living customer's authorized representative
It is tempting to treat this as an extension of the existing policy for customers acting under guardianship or power of attorney. It is not. A living customer under a power of attorney can, in principle, still be reached to confirm the arrangement. A deceased customer cannot confirm anything, ever again, which means every document in the chain has to stand on its own as proof, and the consequences of getting it wrong (releasing a living person's private data or funds to the wrong claimant) are severe and largely irreversible.
The documents an agent should require before doing anything
At minimum: an official death certificate or equivalent government record, and legal proof that the specific person requesting access has actual authority over the estate, typically letters testamentary (if there's a will naming an executor) or letters of administration (if the court appointed one). This documentation chain matters for the same reason decision record-keeping for disputes matters elsewhere: without it, you have no defensible record of why access was granted if the decision is ever challenged later. A grieving family member calling in with good intentions and no court paperwork is not sufficient, no matter how sympathetic the situation is, and no matter how much pressure that creates on a support interaction.
Why the agent should never complete the transfer itself
Even with documents in hand, this is not a case for full agent autonomy. The right design routes every estate-access request to a trained human reviewer, ideally one with legal or compliance training specific to this process, because document verification for probate paperwork varies significantly by jurisdiction and because the stakes of an error are high enough that a second set of eyes is a minimum bar, not an optional safeguard.

What the agent can safely do on its own
The agent can safely acknowledge the request with appropriate care, explain what documentation will be needed, collect and securely store submitted documents in line with your standard data privacy handling for customer records, and set expectations on timeline, all without touching the account itself. This keeps the human load focused on actual verification and decision-making, while the agent still moves the process forward instead of leaving a grieving family member waiting on a first response.
What happens to the account in the interim
Freeze outbound account changes (payment methods, cancellations, data deletion requests) the moment a credible estate-access request is opened, even before verification completes, since a fraudulent claimant racing to make changes before your team catches the discrepancy is a real risk pattern, not a hypothetical one.
FAQ
Can the agent accept a self-written affidavit instead of court documents? Generally no, unless your legal team has pre-approved a specific small-estate affidavit process for your jurisdiction and dollar threshold; that is a legal policy decision, not something an agent should improvise.
What if the estate representative is in a different country than your company? Route to human legal review immediately; cross-border estate law adds enough complexity that no agent-level policy should attempt to resolve it automatically.
Should the agent tell the requester what documents are missing, or stay generic? Being specific about what is still needed is good service and does not itself create legal risk, as long as the agent does not make promises about how the request will ultimately be resolved.
Does this apply to business accounts, not just individual consumer accounts? Business account succession after an owner's death is a related but separate process, usually governed by the business's own legal structure rather than personal probate law, and should have its own documented policy.
