OKLAHOMA INTESTATE INHERITANCE

Oklahoma Inheritance Rules Made Simple

Use this primer to get a quick, clear overview of how property passes in Oklahoma—whether you have a will, want to exercise your spousal share, or just need to know who inherits if you don’t have a plan.

1. Spousal Elective Share

Even if your will leaves you nothing, Oklahoma law protects a surviving spouse:

  • Elective Share (%): 50% of the estate’s “augmented estate.”

  • Augmented Estate includes probate property plus certain non‑probate gifts (e.g., joint accounts, transfers within one year of death).

  • Where to Find It: Okla. Stat. tit. 84 § 43 et seq.

Tip: If your spouse’s will or trust disinherits you, you can claim this share within six months of probate’s opening.

2. Intestate Succession (No Will)

If you die with: Here’s what happens:
Children but no spouse Children inherit everything
 
Spouse but no descendants, parents, or siblings Spouse inherits everything
 
Spouse and descendants from you and that spouse Spouse inherits ½ of your intestate property
Your descendants inherit everything else
 
Spouse and at least one descendant from you and someone other than that spouse Spouse inherits ½ of all property acquired by joint effort during your marriage and splits the remaining intestate property equally with your descendants
Descendants inherit everything else
 
Spouse and parents Spouse inherits all the property acquired by joint effort during marriage, plus ⅓ of the remaining intestate property
Parents inherit everything else
 
Spouse and siblings Spouse inherits all the property acquired by joint effort during your marriage, plus ⅓ of the remaining intestate property
Siblings inherit everything else
 
Parents but no spouse or descendants Parents inherit everything
 
Siblings but no spouse, descendants, or parents Siblings inherit everything

3. Who Counts as a "Sibling"?

Under Okla. Stat. tit. 84 § 31, “siblings” include:

  • Full siblings

  • Half‑siblings (share one parent)

  • Adopted siblings count equally; foster siblings do not automatically inherit.

4. Per Stirpes vs. Per Capita

  • Per Stirpes (by branch): Each branch of the family takes the share their ancestor would have taken.

  • Per Capita (by head): Everyone in the same generation shares equally.

Oklahoma’s Intestate Rules use per stirpes at every generation.

5. Key Takeaways

  • Always Check for a Will or Trust: Even a simple affidavit of heirs can change distribution.

  • Spousal Protections: Surviving spouses can’t be disinherited below the elective share.

  • Know Your Heirs: Half‑siblings and adopted children have standing; foster relationships do not.

  • Timeline: Probate typically takes 6–12 months if uncontested.

6. Next Steps

  1. Review your current estate plan—does it align with Oklahoma’s default rules?

  2. Identify all potential heirs and beneficiaries.

  3. Consider whether a trust structure might better protect your family.
