When an executor or heir asks a brokerage to move a deceased person's stocks, the firm asks a question that sounds odd at first: where exactly did the decedent live? Domicile, the decedent's true legal home, determines which state's estate and inheritance tax rules touch the securities and which law governs the transfer.
The affidavit of domicile is the standard answer: a short sworn, notarized statement of the decedent's residence at death, signed by the executor, surviving owner, or heir, and included in the transfer agent's paperwork package.
Why brokers and transfer agents require it
Domicile decides more than mail delivery. A handful of states impose estate or inheritance taxes, and a transfer agent releasing securities without confirming the decedent's state can find itself between an estate and a tax authority; some states historically required tax waivers before securities of their domiciliaries could be transferred. The affidavit puts the answer on record under oath, shifting responsibility for its accuracy to the affiant. It typically travels in a packet with a certified death certificate, the institution's transfer form, and, where an estate is being probated, the court letters appointing the executor or administrator.
- Certified death certificate: proves the death itself
- Affidavit of domicile: proves where the decedent legally lived
- Letters testamentary or of administration: prove the executor's authority, when probate is open
- Transfer form with medallion signature guarantee: the institution's own instrument, guaranteed by a bank or broker
Domicile is not just an address
A person can have several residences but only one domicile: the place they treated as their permanent home and intended to return to. For a snowbird who split the year between two states, the affidavit should state the true legal home, evidenced by things like the driver's license, voter registration, tax returns, and homestead status. Getting it wrong is not harmless, since two states can each claim a decedent as their domiciliary and tax the estate accordingly. If domicile is genuinely contested or the estate is large enough for state estate tax, the executor should settle the question with a probate attorney before swearing to it.
Sworn means sworn
The affidavit is signed under penalty of perjury and institutions rely on it. State the decedent's actual domicile, not the address that seems most convenient for taxes; a false affidavit exposes the affiant personally.
Completing and delivering the affidavit
Sign before a notary public, since every receiving institution expects a notarized original, and make one original per institution: each brokerage, transfer agent, or fund company handling separate holdings will want its own. Note that a medallion signature guarantee, when the transfer form requires one, is a different thing from notarization and can only be obtained from a participating bank or brokerage where you hold an account. Send the packet by trackable mail and keep copies; transfers of decedent accounts commonly take a few weeks once the paperwork is complete.
Frequently asked questions
Who signs the affidavit of domicile?
The person handling the transfer: the executor or administrator if probate is open, the surviving joint owner for a joint account, the trustee for trust-held securities, or an heir for small estate transfers. The affidavit recites the signer's capacity, and the institution matches it to the rest of the paperwork.
Does an affidavit of domicile need to be notarized?
Yes. It is a sworn statement, and brokerage firms and transfer agents require a notarized original. Some also require a medallion signature guarantee on their own transfer forms, which comes from a bank or broker rather than a notary.
Is an affidavit of domicile the same as an affidavit of residence?
They are related but used differently. An affidavit of domicile concerns a deceased person's legal home and is used for securities transfers. An affidavit of residence usually attests to a living person's address for schools, DMV, or similar purposes. Institutions asking about a decedent's stocks want the domicile version.
Why does the brokerage care which state my parent lived in?
Because the state of domicile controls which estate or inheritance tax rules and which transfer laws apply to the securities. The affidavit documents that answer under oath so the institution can release the assets without exposure.
Do I need a separate affidavit for each brokerage?
Plan on one notarized original per institution. The content is identical; only the securities description changes if you choose to itemize. Ordering the notarizations in one sitting is the efficient way to do it.
