Snapshot

Key default outcomes

  • Intestacy laws determine who receives assets.
  • Probate court oversees the estate and public filings.
  • Guardianship for minors is court-appointed if needed.
  • State and federal tax rules may apply to larger estates.

What happens without a will

Oklahoma intestacy gives the surviving spouse the entire estate if there are no children or parents, but otherwise splits the estate between the spouse, descendants, or parents based on the decedent’s family.

  • If there are no children and no surviving parents, the spouse inherits the entire estate.
  • If there are children, the spouse inherits an equal share with each child.
  • If there are no children but a parent survives, the spouse receives one-half and the parent receives one-half.
  • An heir must survive the decedent by 120 hours to inherit under intestacy.

Probate process

Oklahoma allows a small-estate affidavit for limited personal property after a waiting period when the estate is within a statutory cap.

  • Affidavit collection is available at least 10 days after death.
  • The estate’s value must be $50,000 or less, net of liens and encumbrances.
  • The affidavit can only be used for personal property, not real estate.
  • The small-estate affidavit must be verified under oath before it can be used to transfer property.

Estate and inheritance tax exposure

Oklahoma does not impose a state estate or inheritance tax.

  • No Oklahoma estate tax.
  • No Oklahoma inheritance tax.
  • With no state death tax, tax exposure is primarily federal when the estate exceeds the federal exemption.

Guardianship for minors

Oklahoma courts appoint guardians for minors when parents are unable or unfit, and parents may nominate guardians by will.

  • A guardian may be appointed when parents are deceased or unable to care for the minor.
  • A parent may nominate a guardian by will, subject to court approval.
  • Older minors may nominate a guardian, subject to court approval.
  • Parents can nominate a guardian by will or written instrument, subject to court approval.
