TEDRA Washington law gives families, trustees, and beneficiaries a structured way to resolve disagreements over wills, trusts, and the property a person leaves behind, often without a full courtroom battle. When siblings disagree about what a trust document means, when a beneficiary believes a trustee is not doing the job, or when heirs cannot agree on how an estate should be handled, the Trust and Estate Dispute Resolution Act sets out a clear path from conversation to agreement, mediation, arbitration, or a hearing before a judge. Knowing how that path works gives you real control over how a dispute gets settled.
At Bountiful Law, we help families, personal representatives, and trustees across Snohomish County and King County, Washington, work through trust and estate disagreements so you can move forward with confidence. This guide explains what TEDRA actually covers, how a dispute moves through the options the statute provides, and the timing and notice mistakes that most often weaken an otherwise strong position.
What TEDRA Actually Is in Washington
TEDRA is the common name for chapter 11.96A of the Revised Code of Washington. RCW 11.96A.900 states that the chapter “may be known and cited as the trust and estate dispute resolution act or ‘TEDRA,'” and the act has applied since January 1, 2000.
The Purpose Behind the Trust and Estate Dispute Resolution Act
RCW 11.96A.010 explains that the overall purpose of the chapter is to provide generally applicable rules for resolving disputes and other matters involving trusts and estates. The statute specifically says the provisions are intended to offer nonjudicial methods, such as mediation, arbitration, and agreement, and that judicial resolution is available if those other methods are unsuccessful. That order of preference matters. TEDRA is built on the idea that the people closest to a trust or estate should have a real opportunity to settle their differences before a judge has to step in, which can help protect family relationships.
What Counts as a “Matter” Under TEDRA
TEDRA uses the word “matter” in a broad way. Under RCW 11.96A.030, a matter includes any issue, question, or dispute involving the determination of heirs, beneficiaries, or other persons interested in an estate or trust. It also covers directing a personal representative or trustee to do or to stop doing something in a fiduciary capacity, and questions that arise during administration, such as the construction of wills, trusts, and community property agreements, a change of personal representative or trustee, or a request for an accounting. The definition extends to nonprobate assets as well, including joint tenancy property and accounts with payable on death or transfer on death designations.
Which Court Has Authority Over These Disputes
RCW 11.96A.040 gives the superior court of every county original subject matter jurisdiction over the probate of wills, the administration of estates, and all matters relating to trusts. RCW 11.96A.020 adds that courts have “full and ample power and authority” to administer and settle these matters, even where the statutes do not address a particular situation. For trust disputes, RCW 11.96A.050 generally places venue in the county where a qualified beneficiary resides, where a trustee resides or has a place of business, or where trust real property is located. For a family with a trustee in Everett and beneficiaries in Seattle or Bellevue, that can mean either the Snohomish County Superior Court or the King County Superior Court may be an appropriate place to bring the matter.
How a TEDRA Dispute Actually Moves Forward
One of the most useful features of TEDRA is that it offers several routes to a final resolution, and the parties often have a meaningful say in which route they take. Some disputes end with a signed agreement, while others need a mediator, an arbitrator, or a petition before the court.
Resolving the Matter by Written Agreement
RCW 11.96A.220 allows the parties to resolve a matter by agreement. If all parties agree, the resolution must be evidenced by a written agreement signed by all parties, and that agreement is binding and conclusive on all persons interested in the estate, trust, or nonprobate asset. Under RCW 11.96A.230, a party may file the agreement or a memorandum summarizing it with the court, and once filed, the agreement is deemed approved and is equivalent to a final court order. This nonjudicial binding agreement process is one of the most practical tools in the act, because it allows families to settle questions about distributions, trustee changes, or document interpretation with the same finality as a court order.
Mediation Under RCW 11.96A.300
A party may make a matter subject to mediation by serving a written notice of mediation on the other parties. When the notice is served before any hearing has been set, a party who objects must file and serve a petition objecting to mediation no later than twenty days after receiving the notice, and the court will order mediation to proceed unless good cause is shown. The statute sets qualifications for the mediator, who may be an attorney with at least five years of experience in estate and trust matters or an individual with special skill or training in trust and estate administration or in mediation. RCW 11.96A.300 also requires the mediation to last at least three hours unless the matter is resolved earlier, and any resolution must be documented in a written agreement under RCW 11.96A.220.
Arbitration and Its Appeal Path
Arbitration under RCW 11.96A.310 is generally available only after mediation has concluded, after the court has determined that mediation is not required, when all parties have agreed not to use mediation, or when the court orders arbitration. The arbitrator must issue a final written decision within thirty days after the final arbitration hearing ends. A party who disagrees may appeal by filing a notice of appeal with the superior court within thirty days after the decision was served, which leads to a trial de novo on all issues of law and fact, including a jury if one is demanded. Because that appeal window is short, anyone involved in a TEDRA arbitration should calendar the service date carefully.
Filing a Petition in Superior Court
When agreement and alternative methods do not work, TEDRA provides for judicial proceedings. RCW 11.96A.090 treats a TEDRA judicial proceeding as a special proceeding under the civil rules, and RCW 11.96A.100 provides that it is generally commenced by filing a petition and serving a summons. The answer to the petition must be served and filed at least five days before the hearing, and unless a party requests otherwise, the initial hearing is a hearing on the merits to resolve all issues of fact and law. Testimony may be presented by affidavit.
What Derails Trust and Estate Disputes in Washington
Many TEDRA problems are not about who is right. They are about timing, notice, and procedure. A beneficiary with a strong concern can lose the ability to raise it by waiting too long, and a well-meaning family can end up with an agreement that does not bind everyone because the right people were not included.
Missing the Four-Month Will Contest Window
A challenge to the validity of a will follows its own deadline. Under RCW 11.24.010, a person interested in a will must file a petition contesting its validity within four months immediately following the probate or rejection of the will. The contest is considered commenced when the petition is filed, but the petitioner must personally serve the personal representative within ninety days after filing. If no petition is filed and served within that time, the probate or rejection of the will becomes binding and final. Families in Snohomish County and King County who have concerns about capacity, undue influence, or execution of a will should act promptly once probate begins.
Waiting Too Long on a Breach of Trust Claim
RCW 11.96A.070 limits how long a beneficiary of an express trust has to bring a claim against a trustee for breach of trust. If the trustee delivers a report that adequately discloses a potential claim and informs the beneficiary of the time allowed, the beneficiary generally may not commence a proceeding more than three years after the report was delivered. When that rule does not apply, the claim must generally be brought within three years after the first of the trustee’s removal, resignation, or death, the termination of the beneficiary’s interest, or the termination of the trust. The same section provides that a claim against a personal representative for breach of fiduciary duty must be brought before the personal representative is discharged. Reading trustee reports carefully when they arrive is one of the simplest ways to protect your rights.
Overlooking Notice and Virtual Representation
Under RCW 11.96A.110, notice in a TEDRA judicial proceeding generally must be personally served on or mailed to all parties or their representatives at least twenty days before the hearing, unless a statute or court order provides a different period. TEDRA also allows virtual representation under RCW 11.96A.120, where one person may represent and bind another when there is no conflict of interest on the question at issue. For example, a parent may represent a minor or unborn child when no guardian has been appointed, and a trustee may represent the beneficiaries of a trust. Leaving out a necessary party, or relying on a representative who has a conflict, can undermine an agreement that everyone thought was final.
Final Thoughts
TEDRA gives Washington families a flexible set of tools for resolving disagreements over wills, trusts, and nonprobate assets. The act favors agreement and mediation, provides arbitration with a clear appeal path, and keeps the superior court available when other methods do not resolve the matter. The deadlines in RCW 11.24.010 and RCW 11.96A.070, along with the notice and representation rules, shape what is possible in almost every dispute.
Whether you are a trustee trying to settle a question about your authority, a beneficiary with concerns about how a trust is being handled, or an heir who disagrees with how an estate is moving forward, understanding these rules early can save time and protect important family relationships. A careful review of the documents, the deadlines, and the people who must be included is the right starting point.
