Direct answer
An affidavit of heirship is a sworn legal document used to identify the heirs of a deceased person when formal probate is not required. It can often be used to claim smaller amounts of unclaimed property.
When is an affidavit appropriate?
If the deceased relative did not leave a will and the total value of their estate is small, Oklahoma allows heirs to use an affidavit of heirship to claim assets. The state unclaimed property rules specify the dollar limits and conditions for using this method.
What the affidavit must include
A valid affidavit of heirship typically requires:
- The deceased person's name, date of death, and last known address.
- A complete list of all surviving heirs (spouse, children, etc.).
- Signatures from the heirs.
- Notarization, often requiring the signature of a disinterested third party who knew the family.
