An affidavit of domicile certifies where a deceased person legally lived, so a transfer agent can release stocks and accounts. Learn who signs it and what it includes.

Affidavit of Domicile: Transferring a Deceased Person's Securities

Disclaimer: This article provides general educational information about affidavits of domicile and is not legal advice. Requirements vary by transfer agent and state. For a specific estate, consult a probate attorney or the financial institution involved.


An affidavit of domicile is a sworn statement certifying where a deceased person legally lived (their domicile) at the time of death. It sounds narrow, but it is a routine, required step when transferring stocks, bonds, or brokerage accounts out of a deceased person's name. Without it, a transfer agent usually will not release the securities.

Why Domicile Matters After Death

When someone dies owning securities, the transfer agent (the company that manages the stock or account records) needs to know the person's state of legal residence because:

  • State inheritance or estate tax rules depend on domicile
  • It confirms which state's law governs the transfer
  • It protects the transfer agent against competing claims

The affidavit of domicile provides that certification under oath.

When You Need One

  • Transferring or selling stocks or bonds held in the decedent's name
  • Re-registering a brokerage account to heirs or an estate
  • Cashing in or transferring other securities
  • Almost any time a transfer agent handles a deceased account holder's investments

It is often requested alongside a stock power, a certified death certificate, and proof of the signer's authority (such as letters testamentary).

Who Signs It

The affidavit is signed by the person with authority over the estate:

  • The executor or personal representative, or
  • The administrator (if there is no will), or
  • A surviving joint owner or beneficiary, depending on how the account was held.

What It Typically Contains

  1. The decedent's full name and date of death
  2. The decedent's legal domicile (state and address) at the time of death
  3. A statement of the signer's authority (executor, administrator, joint owner)
  4. A description or reference to the securities or account being transferred
  5. Signature, sworn before a notary
  6. Often accompanied by a certified death certificate and a medallion signature guarantee

The Medallion Signature Guarantee

Many transfer agents require a medallion signature guarantee — a special stamp (different from notarization) that banks and brokerages provide to verify the signer's identity for securities transfers. Ask the transfer agent whether they require a notarization, a medallion guarantee, or both, before you submit.

Common Mistakes

❌ Confusing notarization with a medallion signature guarantee (some need both) ❌ Listing the wrong state of domicile ❌ Forgetting the certified death certificate ❌ Not confirming the transfer agent's exact requirements first ❌ Submitting without proof of the signer's authority over the estate
