Contest a Will in Washington: At a Glance
Here are the Washington facts that decide whether you can contest a will in Washington:
| Deadline to contest | 4 months (RCW 11.24.010). A person interested in the will must file a petition contesting the will within 4 months immediately following the will’s admission to probate (or its rejection), AND must personally serve the petition on the personal representative within 90 days after the date the petition is filed. Filing alone tolls the 4-month limit, but if personal service is not made within 90 days the action is deemed never commenced. If no petition is filed and served in that time, the probate or rejection of the will is binding and final. Tolling for lack of notice is recognized only in narrow circumstances and is not available once the contestant had actual notice and an opportunity to act. |
| What starts the clock | The court’s order admitting the will to probate (or the order rejecting the will) — RCW 11.24.010. The clock does NOT run from the date of death, and it does not restart on receipt of the personal representative’s notice of appointment/notice to heirs under RCW 11.28.237; the 4 months run from probate/rejection itself. A separate 90-day service clock runs from the date the contest petition is filed. |
| Who can contest | “Any person interested in any will” may contest — RCW 11.24.010. “Interested person”/”party” is defined broadly at RCW 11.96A.030 and includes heirs at law who would take by intestacy, beneficiaries named in the challenged will, beneficiaries under a prior or later will, personal representatives, trustees, and creditors and other persons having a claim or property interest against or in the estate. A person with no financial stake in the outcome generally lacks standing. |
| No-contest clause | YES, generally enforceable in Washington, BUT subject to a good-faith / probable-cause exception. Washington has no statute governing in terrorem clauses; the rule is case law. In re Estate of Kubick, 9 Wn. App. 413, 513 P.2d 76 (1973) holds that a challenge brought in good faith and with probable cause does not trigger forfeiture, and that losing the contest does not by itself show bad faith or lack of probable cause; a contestant who fully and fairly disclosed the material facts to an attorney and acted on that advice is treated as having probable cause. Courts also construe forfeiture clauses strictly against forfeiture. |
| What the filing is called | “Petition contesting the validity of the will” (commonly called a will contest petition, and frequently filed as a TEDRA petition under RCW 11.96A.100), containing the contestant’s objections and exceptions to the will or to its rejection. It is filed in the existing probate cause in the superior court that admitted or rejected the will, then personally served on the personal representative within 90 days. |
| Court | Washington State Superior Court — the superior court of the county having jurisdiction over the probate, i.e., where the will was admitted or rejected (RCW 11.24.010; RCW 11.96A.040, 11.96A.050). Washington has no separate surrogate’s or orphans’ court; superior courts have original probate jurisdiction, and larger counties (e.g., King County) run a dedicated ex parte and probate department. |
| Jury trial | NO as a general matter. RCW 11.24.010 states that issues respecting competency of the deceased, execution under restraint or undue influence or fraudulent representations, “or for any other cause affecting the validity of the will,” “shall be tried and determined by the court.” RCW 11.96A.170 addresses procedure only where a party is otherwise entitled to a jury and one is demanded; where no jury is demanded or available, the court tries the issues and enters written findings. You may want to confirm with a licensed Washington attorney whether any particular related claim (for example, a damages claim joined with the contest) carries a jury right. |
| Typical cost | 15000 to 40000 for a typical contested Washington will/estate case taken through litigation, with simpler matters resolved by mediation or a TEDRA agreement often falling below that and multi-party or multi-day-trial cases running well above it. This range comes from Washington attorney fee surveys, not from an official state fee schedule, so treat it as an estimate; costs vary by county, estate size, and number of parties. Note that under RCW 11.96A.150 the superior court (or an appellate court) has discretion to order costs and reasonable attorneys’ fees paid by any party, out of the estate or trust, or out of a nonprobate asset at issue — so who ultimately pays is not fixed at the outset. |
The Deadline to Contest a Will in Washington
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 Washington
Under RCW 11.24.010 the recognized grounds are: (1) lack of testamentary capacity — incompetency of the deceased to make a will (see RCW 11.12.010, requiring age 18 and sound mind); (2) execution under restraint or duress; (3) undue influence; (4) fraud / fraudulent representations;
(5) “any other cause affecting the validity of the will or a part of it,” which in Washington practice includes improper execution (failure to meet RCW 11.12.020 — signed by the testator and attested by two competent witnesses), forgery, mistake, and revocation of the will (RCW 11.12.040).
A contest may challenge the entire will or only part of it.
Who has to prove what: The contestant carries the burden. A will admitted to probate is presumed valid, and the contestant must overcome that presumption by clear, cogent, and convincing evidence (Dean v. Jordan, 194 Wash. 661, 79 P.2d 331 (1938)). Washington recognizes a rebuttable presumption of undue influence where suspicious facts combine — the Dean v.
Jordan factors: (1) age and physical condition of the testator; (2) prior mental history; (3) a fiduciary or confidential relationship between the testator and the beneficiary; (4) opportunity to exert undue influence; (5) participation by the beneficiary in procuring the will; (6) an unnaturally large share of the estate going to that beneficiary.
When the presumption arises, the will proponent must come forward with rebutting evidence, but the ultimate burden of persuasion stays with the contestant at the clear, cogent, and convincing standard.
Who Can Contest a Will in Washington
“Any person interested in any will” may contest — RCW 11.24.010. “Interested person”/”party” is defined broadly at RCW 11.96A.030 and includes heirs at law who would take by intestacy, beneficiaries named in the challenged will, beneficiaries under a prior or later will, personal representatives, trustees, and creditors and other persons having a claim or property interest against or in the estate.
A person with no financial stake in the outcome generally lacks standing. Being unhappy with the will is not standing; losing something because of it is. Check the earlier will and the intestate rules for Washington before filing, because they decide whether you are an interested person.
No-Contest Clauses in Washington
YES, generally enforceable in Washington, BUT subject to a good-faith / probable-cause exception. Washington has no statute governing in terrorem clauses; the rule is case law. In re Estate of Kubick, 9 Wn. App.
413, 513 P.2d 76 (1973) holds that a challenge brought in good faith and with probable cause does not trigger forfeiture, and that losing the contest does not by itself show bad faith or lack of probable cause; a contestant who fully and fairly disclosed the material facts to an attorney and acted on that advice is treated as having probable cause. Courts also construe forfeiture clauses strictly against forfeiture.
The Steps to Contest a Will in Washington
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 — “Petition contesting the validity of the will” (commonly called a will contest petition, and frequently filed as a TEDRA petition under RCW 11.96A.100), containing the contestant’s objections and exceptions to the will or to its rejection. It is filed in the existing probate cause in the superior court that admitted or rejected the will, then personally served on the personal representative within 90 days..
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. Washington’s Trust and Estate Dispute Resolution Act (TEDRA), Chapter 11.96A RCW, is expressly designed for this.

RCW 11.96A.220 authorizes a binding written nonjudicial dispute resolution agreement among all parties having an interest in the subject matter, which may resolve any matter — including a will contest — without court approval; RCW 11.96A.230 allows the agreement to be filed with the court, where it has the same effect as a court order, and RCW 11.96A.240 provides for judicial approval of an agreement.
RCW 11.96A.260 through 11.96A.320 provide a mediation procedure (any party may serve a notice compelling mediation), with mediator compensation borne equally by the parties, and RCW 11.96A.330 provides for binding arbitration.
Other Washington rules: (1) NO ante-mortem/pre-death will validation in Washington — a will’s validity cannot be adjudicated while the testator is alive. (2) Dual clocks: the 4-month filing deadline plus a hard 90-day personal-service requirement on the personal representative (RCW 11.24.010); missing the service step voids the contest even if it was filed on time.
(3) Self-proved wills: under RCW 11.20.020 attesting witnesses may sign an affidavit written on, affixed to, or logically associated with the will (including a photographic copy or an electronic will), which lets the will be admitted without live witness testimony; the order admitting the will is prima facie evidence of its validity, and Washington by statute recognizes electronic wills (Chapter 11.12 RCW / Uniform Electronic Wills provisions).
(4) Nonintervention powers: most Washington probates are “nonintervention” under Chapter 11.68 RCW, so the estate proceeds with almost no court supervision — a contestant must act affirmatively within the 4 months rather than wait for a court hearing. (5) TEDRA (Chapter 11.96A RCW) supplies the umbrella procedure for contests, including virtual representation of minors and unborn/unascertained beneficiaries (RCW 11.96A.120) and broad judicial discretion over fees (RCW 11.96A.150).
(6) Community property: Washington is a community property state, and a surviving spouse’s or registered domestic partner’s one-half community property interest and any community property agreement (RCW 26.16.120) may control assets regardless of the will’s terms. (7) Washington has no statutory elective share for a disinherited spouse, and no pretermitted-spouse or omitted-child claim is itself a “will contest” — omitted-child rights arise separately under RCW 11.12.091.
Nothing here is individualized legal advice, and no outcome can be guaranteed; many families can resolve these disputes through a TEDRA agreement or mediation, but you should check with the superior court in the county handling the probate or a licensed Washington attorney about your specific situation and dates.
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: Washington 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 Washington, 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 Washington
A will contest is a lawsuit about the document, not about fairness. When you contest a will in Washington, 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 Washington 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.
