Contest an Estate Accounting After It Was Approved — Wyoming FAQ

Short answer: Reopening or contesting an estate accounting more than a year after the court approved it in Wyoming is possible but difficult. You usually must show a narrow legal ground (for example, fraud, mistake, lack of jurisdiction, or newly discovered evidence) and ask the court to set aside or reopen the prior order. Remedies and procedures vary; acting quickly and with an attorney is important.

Detailed answer — what you need to know

This section explains, in plain language, how Wyoming law treats a previously approved estate accounting and what steps a beneficiary or interested person can take when more than a year has passed since the court approved it. This is educational information only and not legal advice.

1. What does a court approval of an accounting mean?

When a personal representative (executor or administrator) presents an accounting and the court approves it, the court is confirming the fiduciary’s actions for the period covered by that accounting. Approval generally finalizes the accounting and, for many purposes, prevents later challenges to those items that were disclosed and could have been contested at the time.

2. Is there a strict one-year limit that forever bars challenges?

Wyoming does not have a simple, universal rule that allows anyone to challenge an approved accounting at any time. Instead, whether you can challenge depends on the type of relief you request and the legal grounds you can establish. Some probate deadlines (for example, creditor claim periods) are fixed and short. Challenges to a court’s prior order typically require you to use post-judgment procedures that have their own standards and timelines.

3. Typical legal grounds to reopen or challenge an approved accounting

• Fraud or misrepresentation: If the fiduciary deliberately concealed assets, forged records, or otherwise committed fraud, a court may set aside the approval.
• Material mistake or clerical error: A clear mistake in the accounting or a mathematical or clerical error that changes the result significantly may justify reopening the account.
• Newly discovered evidence: Evidence that could not reasonably have been discovered before the approval and that would likely change the outcome may justify relief.
• Lack of jurisdiction or notice defects: If you were not given required notice of the settlement or the court lacked jurisdiction, the order approving the accounting may be voidable.

4. Procedures to ask the court to reopen or set aside an approval

There are two common procedural paths:

• Petition in the probate case to reopen the settlement: You may file a petition in the probate court explaining the grounds (fraud, mistake, lack of notice, etc.) and asking the judge to set aside or modify the prior allowance. The probate court has equitable power to revisit its orders in appropriate cases.
• Motion for relief from judgment (post‑judgment relief): If the probate court’s rules or the Wyoming Rules of Civil Procedure apply, you may file a motion under the post‑judgment relief rules (for example, motions comparable to Rule 60(b) in many jurisdictions) asking the court to vacate its prior order for reasons like fraud or newly discovered evidence. These motions have specific procedural requirements and may have time-based elements for some grounds.

Which path is correct depends on local practice in the district court handling probate and the specific facts. The probate file and local court rules will show how similar petitions have been handled in your county.

5. Burden of proof and practical hurdles

• You must present persuasive proof of the ground you assert (fraud, mistake, new evidence, lack of notice, etc.).
• The court will balance finality (the need for stability in probate matters) against fairness to the injured party.
• Delay can hurt your case. The longer you wait, the harder it can be to persuade a judge to reopen settled matters, especially if distributions have already been made to innocent third parties.

6. Possible outcomes and remedies

• The court may reopen the accounting for a limited issue or for the whole accounting period.
• The court may order a surcharge (financial liability) against the fiduciary for mismanagement or dishonesty.
• The court may remove the fiduciary, order repayment, or require additional accounting steps.
• If distributions have already been made, the court will consider fairness to recipients and may limit relief or fashion equitable remedies.

7. Deadlines you should check immediately

• Creditor claims: Wyoming probate law sets specific deadlines for creditor claims. Missing those deadlines can bar creditor recovery. See the Wyoming Legislature and local court guidance for creditor claim timing.
• Post‑judgment relief: Procedural rules that allow vacating an order often contain deadlines for some grounds (for example, claims of mistake or newly discovered evidence commonly require prompt action once discovered).

Because these deadlines and rules can vary by county and by the specifics of the probate order, check the probate court file and consult an attorney promptly.

8. Where to look for Wyoming statutes and court rules

• Wyoming statutes and probate provisions: the Wyoming Legislature website — https://wyoleg.gov/ (use this site to search Title and chapters that govern administration of estates).
• Wyoming Judicial Branch (court rules, forms, and local probate information): https://www.courts.state.wy.us/

Those resources will point you to the exact statutes and rules that control deadlines and procedures in your county.

9. Practical next steps to take right now

1. Obtain a copy of the probate file and the court order approving the accounting from the district court clerk.
2. Review the approval order for any language about finality, appeals, or deadlines.
3. Preserve all documents and evidence that support your claim (emails, bank statements, appraisals, correspondence with the fiduciary).
4. Ask the court clerk whether there are standing local rules or forms for reopening probate accounts.
5. Consult a Wyoming probate attorney immediately — many issues require prompt action and strict procedural compliance.

Helpful Hints

• Do not rely on informal promises by the fiduciary. Get records and orders in writing from the court file.
• If you suspect fraud, take steps right away to preserve bank statements and documents and consider seeking an emergency accounting or temporary injunction to prevent dissipation of assets.
• Track dates carefully: the date on which you discovered the fraud or new evidence can be crucial for timing a motion to reopen.
• Even if more than a year has passed, you may have options — but the strength of those options often depends on the quality of the evidence and the reason for the delay.
• Contact the probate clerk for public file access; copies of the approved accounting and the court’s order are essential for evaluating your position.
