Will Contests & Estate Disputes – Protecting Your Rights in Probate

When the Validity of a Will Is Questioned

Will contests may arise over lack of capacity, undue influence, fraud, mistakes in execution, or a later superseding will. Disputes can also involve beneficiary designations or trusts. Strict deadlines apply once probate opens in Washington, so early legal guidance is essential. Tresa A. Sadler PLLC advises heirs, beneficiaries, and personal representatives from Mill Creek to Seattle on the best course of action.

Challengers and Defenders—Balanced, Strategic Advocacy

We represent parties seeking to challenge a suspicious will and those defending a valid will against meritless claims. Our approach prioritizes evidence gathering, clear communication, and opportunities for negotiated resolution before pursuing courtroom remedies.


Mediation First, Litigation When Necessary


Family conflicts are emotional and costly. We use settlement conferences and mediation to resolve disagreements efficiently while preserving relationships when possible.

Understanding No-Contest Clauses


Some wills include clauses that penalize unsuccessful challengers. We analyze your options and risks before any filing, so you proceed with eyes open.

Act Quickly and Preserve Evidence


Probate dispute timelines are tight. We secure medical records, witness statements, and document histories to build a credible case.

Managing Costs and Delays


Contests can pause distributions and increase expenses. We assess strengths and settlement ranges early so clients can make informed decisions.

  • Can a notarized will still be contested?

    Yes—if there’s evidence of undue influence, lack of capacity, or other valid grounds.

  • What if I suspect elder abuse led to changes?

    We investigate medical records and timelines, and work with experts to evaluate the claim.

  • Will heirs receive funds during a dispute?

    Distributions are often paused until the court resolves the issues.
