Probate in Oklahoma

Petition for Probate of Will

First, the person named as executor needs to obtain a hearing date by filing the following with the district court[4]:

  • Last Will and Testament
  • Petition for Probate of Will

The petitioner must notify interested parties and obtain an Order Admitting Will to Probate at the hearing.[5] Letters Testamentary are issued after the petitioner posts bond, appointing them as executor.[6] They must file a Statement of Claims, Inventory, and Notice to Creditors, then publish the Notice, send it to creditors, and file proofs of notice.[7] 

After resolving estate debts, the executor must file a Petition for Final Accounting with the court, obtain a court date, and again notify interested parties.[8] At the hearing, the executor must provide an accounting of the estate and list of creditors.[9] If approved, the court will issue a Decree of Distribution, authorizing the executor to distribute assets.[10] 

Small Estates

For estates worth $50,000 or less, the decedent’s successors can use a Small Estate Affidavit to collect property without probate.[11]
