Discovering another will after a parent’s death can deepen grief and raise doubts. It might change who receives property or manages the estate.
If you found a later version, knowing how courts compare the documents can help protect your parent’s wishes. It may also preserve evidence before a filing deadline passes.
The result depends on each document’s validity, language and supporting proof. Those factors can produce three common outcomes.
A valid newer will may revoke the earlier version
A properly executed later will often govern the estate. In Washington, a subsequent will can revoke an earlier document when it expressly cancels it or contains inconsistent terms. Revocation may affect the entire prior instrument or only conflicting provisions.
For example, a 2024 will might leave a home to your sibling instead of all children. The court could enforce that gift while retaining compatible instructions.
An invalid newer document may leave the older will intact
A later date alone cannot establish validity. A traditional will generally requires the testator’s signature and two competent witnesses. Concerns may arise if the witnesses did not observe the execution, someone forged the signature or your parent lacked testamentary capacity.
If the newer document fails legal requirements, it may not revoke the prior will. The probate court could then enforce the older version if your parent had not revoked it through another legally recognized method.
The court may resolve a dispute
Conflicting documents can lead to litigation. An interested person generally must file a contest within four months after the court admits or rejects the will. Claims may involve undue influence, fraudulent representations or improper execution.
Those challenges focus on the will’s validity, but the absence of a signed original often raises a different question about evidence. Washington requires clear, cogent and convincing proof of its provisions, including witness testimony about its contents or the authenticity of a copy.
How a timely action can protect your parent’s intent
Preserve every version, envelope and message. Avoid writing on the papers or removing staples because physical details could reveal how each instrument was prepared.
Those measures may give an attorney useful information when assessing authenticity. Counsel can determine which document governs, what evidence supports it and which deadlines apply. Prompt review may also support a request to pause harmful distributions while the court considers the dispute.
