Short answer (overview)

If a personal representative (executor/administrator) filed a final accounting in your parent’s probate and you did not receive required notice, you can ask the court to reopen or set aside that accounting and require a new hearing. Under Oklahoma probate procedure the court can provide relief when interested persons were not given proper notice or when an accounting was unfair, incomplete, fraudulent, or otherwise prejudicial. The practical steps are: get the court file, confirm what notice (if any) was sent, file a written objection or motion to set aside the settlement, ask for a new accounting or rehearing, and consider asking the court for remedies such as surcharge, removal of the personal representative, or recovery of estate assets. See Oklahoma statutes on probate (Title 58) for the governing framework: https://www.oklegislature.gov/

Detailed answer — how this works under Oklahoma law

Start by understanding two basic concepts:

• Interested person: Oklahoma probate treats heirs, devisees, beneficiaries, and certain creditors as “interested persons” with a right to notice and an opportunity to object to accountings and other probate actions.
• Personal representative duties: The personal representative must collect estate assets, preserve them, pay valid claims, and account to the court and interested persons. A final accounting is the personal representative’s report showing what they received, paid, and distributed.

If you were not notified, your remedies usually include these options (the probate court has broad equitable power to correct unfair or improper settlements):

1. Obtain the probate file and docket immediately.

   Go to the county court where your parent’s estate is open and request the file or view the electronic docket. Obtain a copy of the will (if any), letters testamentary or of administration, the inventory/appraisement, the final accounting, any notice documents, and the court’s order approving the final accounting (if one exists).

2. Confirm whether the court required notice and whether it was given.

   Compare the names and addresses listed on any notice certificate to your name and address at the time. If you are a statutory heir or a named beneficiary under the will and the court record shows no notice to you, that is a strong basis to seek relief.

3. File a written objection or motion to set aside the accounting.

   Tell the court you were an interested person and you did not receive the notice required to give you a meaningful opportunity to review and object to the accounting. Ask the court to set aside the settlement or to schedule a rehearing so you can examine the accounting and raise objections. If an order approving the accounting is already entered, you can request relief from that order and a new hearing.

4. Explain the legal grounds and the relief requested.

   Common legal grounds: lack of notice to an interested person, mistake, excusable neglect, fraud or concealment, and breach of fiduciary duty by the personal representative. Typical relief: vacate the approval order, require a new or supplemental accounting, surcharge the personal representative for losses, remove the personal representative, or order return of improperly distributed assets.

5. Gather documentary evidence.

   Bring your relationship to the decedent (birth certificate or other proof), copies of the probate filings, any communications from the personal representative, your address history, account or bank statements showing suspicious distributions, and anything showing the personal representative concealed information.

6. Ask for temporary relief if assets are at risk.

   If the estate’s remaining assets are being dissipated or are vulnerable, move for injunctive relief or for the court to freeze distributions pending resolution.

7. Consider removal or surcharge claims.

   If the personal representative failed to account properly or breached fiduciary duties, ask the court to remove them and to hold them financially responsible (surcharge) for losses caused by their actions.

8. Meet deadlines and follow local rules.

   Probate courts have timing and service requirements. If a statutory objection period applies, file your objection as soon as possible. Even when a deadline has passed, courts sometimes provide relief when no notice was given or where fraud occurred—so act quickly.

Relevant Oklahoma law and resources: Oklahoma’s probate statutes are in Title 58 of the Oklahoma Statutes (Probate Procedure). The Oklahoma Legislature site provides access to those statutes and is the place to look for the specific rules that apply to accounting, notice, and removal of personal representatives: https://www.oklegislature.gov/

Because local courts implement procedural details, also check the county probate court rules and contact the county court clerk for local filing requirements and forms.

Hypothetical example (illustrates how a challenge might succeed)

Facts: Your parent died and your sibling was appointed personal representative. Months later you learn the sibling filed a final accounting and the court entered an order approving distribution. You never received notice because the sibling used an old address and did not mail notice to all heirs or beneficiaries.

Action: You obtain the court file and find no certificate of mailing to your current address. You file a verified motion asking the court to vacate the order approving the accounting because you were an interested person who did not receive required notice and therefore had no opportunity to object. You attach proof of your relationship and current address, and request a new hearing and production of financial records. The court reopens the matter, orders the personal representative to produce bank records, and either requires a corrected accounting or, if misconduct is shown, removes the personal representative and orders surcharge.

Outcome: The court’s action turns on whether you were an interested person, whether notice was required and not given, and whether reopening is needed to prevent injustice. Courts generally prefer to ensure interested persons had the opportunity to be heard.

Helpful hints (practical checklist)

• Immediately get a copy of the probate docket and all filings from the county court clerk.
• Confirm whether the estate was intestate (no will) or there is a will that names beneficiaries.
• Document your address at the time of the notice and any communications with the personal representative.
• If an order already approved the accounting, file a motion to set aside or vacate the order and ask for a rehearing; ask for expedited relief if assets are being dissipated.
• Preserve evidence of any suspected concealment, improper distributions, or breaches of fiduciary duty (bank records, transfer receipts, emails, text messages).
• Check local county court rules for specific filing forms and service requirements.
• Meet and confer if appropriate — sometimes disputes are resolved by producing additional detail and a corrected accounting without a long court fight.
• Act quickly — the longer you wait, the harder it may be to reopen an approved accounting or recover distributed assets.
• Talk to an attorney experienced in Oklahoma probate — they can draft the motion, calculate deadlines, and present evidence and arguments to the court.

When to get a lawyer

If substantial assets are involved, if you suspect fraud or concealment, if the personal representative refuses to account, or if you need immediate injunction-type relief to protect estate assets, consult a probate attorney promptly. An attorney can prepare a competent motion, represent you at hearings, and help pursue remedies such as surcharge or removal.
