Contest a Will in Pennsylvania: At a Glance
Here are the Pennsylvania facts that decide whether you can contest a will in Pennsylvania:
| Deadline to contest | 1 year (12 months) from the date of the Register of Wills’ decree admitting the will to probate — 20 Pa.C.S. § 908(a); on petition of any party in interest the Orphans’ Court may shorten that period to 3 months (20 Pa.C.S. § 908(a)). A contest may also be raised BEFORE probate by filing a caveat with the Register of Wills under 20 Pa.C.S. § 906 (no fixed deadline, but it must be filed before the will is admitted). Missing the 1-year appeal window generally bars the challenge. |
| What starts the clock | Entry of the Register of Wills’ decree admitting the will to probate (the probate decree) — NOT the date of death, not the notice of estate administration, and not the date the contestant learned of the will. 20 Pa.C.S. § 908(a). A separate 10-day clock applies if the court orders an appeal bond under 20 Pa.C.S. § 908(b) — failure to file the ordered bond within 10 days is treated as abandonment of the appeal. |
| Who can contest | Any “party in interest” who is aggrieved by the Register’s decree — 20 Pa.C.S. § 908(a). This includes intestate heirs who would take if the will failed, beneficiaries named in a prior will, beneficiaries under the challenged will whose share would increase, and a fiduciary whose estate or trust is aggrieved. The statute expressly excludes an executor named in an instrument from being a party in interest merely by virtue of that designation when probate is refused. Creditors generally do not have standing to contest the will itself; they pursue claims against the estate instead. |
| No-contest clause | YES with a probable-cause exception. No-contest (in terrorem / forfeiture) clauses are valid and enforceable in Pennsylvania wills and trusts, BUT 20 Pa.C.S. § 2521 provides that such a provision “is unenforceable if probable cause exists” for instituting the proceedings. Pennsylvania courts construe forfeiture clauses strictly because enforcement causes complete forfeiture. (Parallel trust provision: 20 Pa.C.S. § 7710.5.) |
| What the filing is called | Two routes. (1) Before probate — a “caveat” filed with the county Register of Wills (20 Pa.C.S. § 906), which suspends probate and, when contested, is certified to the Orphans’ Court. (2) After probate — an “appeal from the decree of the Register of Wills,” filed as a petition/appeal in the Orphans’ Court Division of the Court of Common Pleas of the county where the estate is being administered (20 Pa.C.S. § 908), which typically results in the court framing an issue and holding a hearing. |
| Court | The Orphans’ Court Division of the Court of Common Pleas in the county where the decedent was domiciled. The Register of Wills of that county handles the initial probate and any pre-probate caveat; contested matters go to Orphans’ Court. Jurisdiction: 20 Pa.C.S. § 711(1). |
| Jury trial | NO as a matter of right in a will contest. Under 20 Pa.C.S. § 777(a), the Orphans’ Court Division may, in its discretion, impanel a jury to decide a question of fact, but “the verdict of the jury shall be advisory only.” (A binding jury verdict is available only in incapacity proceedings under § 777(b).) Will contests are therefore decided by the Orphans’ Court judge. |
| Typical cost | UNVERIFIED — Pennsylvania publishes no official cost range for contested will litigation. Costs vary widely by county, whether expert medical testimony is needed, and whether the case settles; filing fees are set county-by-county by each Register of Wills and Clerk of Orphans’ Court. Ask a licensed Pennsylvania attorney for a fee estimate on your specific facts. |
The Deadline to Contest a Will in Pennsylvania
The window is short in some states and long in others, and it is measured from a specific event rather than from the day you learned about the will. That is why the first thing to find out is the date the will was admitted and whether you received formal notice. If the deadline has not run, everything else on this page is available to you.
If it has, the remaining options are narrow and usually involve proving you never got the notice the law required.
Grounds to Contest a Will in Pennsylvania
Lack of testamentary capacity; undue influence; forgery; fraud; duress; improper execution (failure to meet 20 Pa.C.S. § 2502 — writing signed by the testator at the end); revocation by a later will, codicil or physical act (20 Pa.C.S. § 2505); and mistake. Undue influence and lack of capacity are by far the most commonly pleaded grounds.
Who has to prove what: The proponent first carries the burden of proving the will was duly executed (aided by the self-proving affidavit under 20 Pa.C.S. § 3132.1 or the two-witness proof of 20 Pa.C.S. § 3132). The burden then shifts to the contestant, who must prove lack of testamentary capacity or undue influence by clear and convincing evidence.
Presumption of undue influence: under the three-part test of In re Estate of Clark, 461 Pa.
52 (1975), if the contestant shows by clear and convincing evidence (1) a confidential relationship, (2) that the person in that relationship received a substantial benefit under the will, and (3) that the testator suffered from weakened intellect, the burden shifts to the proponent to prove the absence of undue influence by clear and convincing evidence. Fraud and forgery must also be proved by clear and convincing evidence.
Who Can Contest a Will in Pennsylvania
Any “party in interest” who is aggrieved by the Register’s decree — 20 Pa.C.S. § 908(a). This includes intestate heirs who would take if the will failed, beneficiaries named in a prior will, beneficiaries under the challenged will whose share would increase, and a fiduciary whose estate or trust is aggrieved.
The statute expressly excludes an executor named in an instrument from being a party in interest merely by virtue of that designation when probate is refused. Creditors generally do not have standing to contest the will itself; they pursue claims against the estate instead. Being unhappy with the will is not standing; losing something because of it is.
Check the earlier will and the intestate rules for Pennsylvania before filing, because they decide whether you are an interested person.
No-Contest Clauses in Pennsylvania
YES with a probable-cause exception. No-contest (in terrorem / forfeiture) clauses are valid and enforceable in Pennsylvania wills and trusts, BUT 20 Pa.C.S. § 2521 provides that such a provision “is unenforceable if probable cause exists” for instituting the proceedings. Pennsylvania courts construe forfeiture clauses strictly because enforcement causes complete forfeiture. (Parallel trust provision: 20 Pa.C.S. § 7710.5.)
The Steps to Contest a Will in Pennsylvania
Step one is the deadline check above. Step two is evidence: the medical records around the signing date, the names of the witnesses, the drafting lawyer’s file, and the financial records that show who benefited. Step three is the filing — Two routes.
(1) Before probate — a “caveat” filed with the county Register of Wills (20 Pa.C.S. § 906), which suspends probate and, when contested, is certified to the Orphans’ Court.
(2) After probate — an “appeal from the decree of the Register of Wills,” filed as a petition/appeal in the Orphans’ Court Division of the Court of Common Pleas of the county where the estate is being administered (20 Pa.C.S. § 908), which typically results in the court framing an issue and holding a hearing..
Step four is discovery and, in most cases, a settlement conference; the small minority that reach trial are decided by the judge.
Settling Instead of Fighting
YES. Pennsylvania strongly favors resolving contests by agreement. Family settlement agreements among all interested parties are recognized at common law and routinely used to close estates without litigation.

Court-approved compromise is authorized by 20 Pa.C.S. § 3323 (“Compromise of controversies”), which lets the court, on petition of the personal representative or any party in interest and after notice, enter a decree authorizing settlement of “any question or dispute concerning the validity or construction of any governing instrument” — and such an order is not subject to collateral attack.
Many counties also offer or order Orphans’ Court mediation under local rules. A family settlement agreement requires the consent of every interested party.
Other Pennsylvania rules: Several unique Pennsylvania features. (1) NO WITNESSES REQUIRED AT EXECUTION — 20 Pa.C.S. § 2502 requires only that the will be in writing and signed by the testator at the end; Pennsylvania is one of the few states with no attesting-witness requirement (witnesses are required only where the testator signs by mark, or another person signs for the testator).
Witnesses are instead produced at probate: two witnesses must prove the signature under 20 Pa.C.S. § 3132. (2) SELF-PROVED WILLS — an attested will may be made self-proved by testator acknowledgment plus witness affidavits before an officer authorized to administer oaths (20 Pa.C.S. § 3132.1), which streamlines probate.
(3) TWO-TRACK CONTEST — a caveat before probate (§ 906) versus an appeal after probate (§ 908); the route determines the procedure and deadline. (4) APPEAL BOND — the Orphans’ Court may require a contestant to post a surety bond for costs (§ 908(b)); it must be filed within the time ordered or the appeal is deemed abandoned.
(5) THE 1-YEAR PERIOD CAN BE SHORTENED to 3 months by court order on petition of a party in interest, so an estate can compress the contest window. (6) NO ANTE-MORTEM PROBATE — Pennsylvania has no statute allowing pre-death validation of a will; validity is tested only after death. (7) Section 908 does not apply to inheritance tax appeals or to appeals specially regulated by law (§ 908(d)).
The Evidence That Wins or Loses a Will Contest
Capacity cases turn on the weeks around the signing: the medical chart, prescriptions, a dementia diagnosis, and what the drafting lawyer and the witnesses saw that day. A will signed in a lawyer’s office with two disinterested witnesses and a self-proving affidavit is hard to attack; a will signed at a kitchen table with the main beneficiary present is not.
Undue influence cases turn on the relationship — who drove the parent to the appointment, who chose the lawyer, who was in the room, and whether the new will departed sharply from earlier ones and from what the parent said to other people.
Improper execution is the narrowest ground and the cleanest: Pennsylvania sets exact witness and signature rules, and a will that misses them fails regardless of what the signer intended. Before you contest a will in Pennsylvania, gather the prior wills, the medical releases, and the names of everyone at the signing.
Most of that evidence has to be requested formally once the case is filed, and the deadline does not wait for it.
What to Expect When You Contest a Will in Pennsylvania
A will contest is a lawsuit about the document, not about fairness. When you contest a will in Pennsylvania, the court asks whether the person who signed it had capacity, signed it freely, and signed it correctly. It does not ask whether the split was reasonable. That is why the strongest cases rest on medical records and witness accounts from the weeks around the signing.
Most families who contest a will in Pennsylvania settle. Courts encourage it, many states have family settlement rules that let the heirs agree to a different division, and a settlement avoids the cost and delay of trial. The deadline, the grounds, and the no-contest clause above are the three facts that set your bargaining position before any of that begins.
