Challenging Paternity After 60 Days: Proving Fraud, Duress, or Material Mistake in WA

What Happens After 60 Days in Washington?

If you signed a Voluntary Acknowledgment of Paternity (VAP) in Washington and missed the 60-day administrative rescission window, the document carries the exact same legal weight as a judge's final court order. You cannot simply mail a letter to cancel it. Instead, under Wash. Rev. Code § 26.26A.240, you must file a formal lawsuit to challenge the document. The law severely limits the reasons you can use to challenge it, and the burden of proof rests entirely on you. You generally have a four-year statute of limitations to bring this challenge. Attempting this complex litigation without representation is incredibly difficult, so we urge you to find an experienced local litigation attorney through our directory.

Step-by-Step Process in Washington Superior Courts

Challenging parentage is a formal civil lawsuit. Whether you file in the Superior Court of Washington, Pierce County, Tacoma or the Superior Court of Washington, Spokane County, Spokane, the procedural steps are rigorous.

Step 1: Filing the Petition

Your attorney must draft and file a formal petition with the court. The correct document is Form FL Parentage 301, Washington, Superior Court, Petition to Decide Parentage. Along with this petition, your lawyer will file a sworn declaration stating the exact legal grounds for challenging the VAP (fraud, duress, or mistake of fact).

Step 2: Serving the Mother

Once the lawsuit is filed, you cannot simply hand the papers to the mother. You must arrange for formal service of process. Usually, a professional process server or a county sheriff will deliver the summons and petition to the mother, giving her the legal right to respond and contest your challenge.

Step 3: Requesting a Court-Ordered DNA Test

If you are claiming a biological mistake, your attorney will file a motion asking the judge to order genetic testing. If the judge agrees that your petition has merit, they will issue an order compelling both the child and the mother to submit to DNA testing at an accredited state laboratory.

Step 4: Final Hearing

If the DNA results prove you are not the biological father, or if you provide overwhelming evidence of fraud, the judge will hold a final hearing. The judge will then issue a court order explicitly invalidating the original acknowledgment and instructing the state to remove your name from the vital records.

Proving the Mother Intentionally Lied (Fraud)

One of the allowable legal grounds is fraud. In Washington courts, fraud means that the mother intentionally lied to you about your paternity with the specific goal of getting you to sign the acknowledgment. For instance, if she knew she was intimate with another man during the time of conception but deliberately hid this fact from you to secure your signature, that is fraud. Proving this often requires producing text messages, emails, or witness testimony showing she knew you were not the father when the paper was signed. Precedents like In re Parentage of J.M.K., 155 Wash. 2d 374 (WA Supreme Court 2005) highlight how strictly courts evaluate the evidence surrounding parentage challenges.

Threats from Maternal Family (Duress)

Duress means you were forced into signing the document against your own free will. If the mother's family cornered you in the hospital room, threatened you with physical harm, or threatened to ruin your career if you did not sign the acknowledgment immediately, this constitutes duress. Proving duress is difficult because you must show that your fear was so severe that it entirely overcame your ability to make a voluntary choice.

Biological Misunderstandings (Material Mistake of Fact)

The most common ground used to challenge a VAP is a 'material mistake of fact.' This occurs when both you and the mother genuinely, but mistakenly, believed you were the biological father at the time of signing. There was no intentional lie; the timeline just seemed to align. If a subsequent medical examination or DNA test unexpectedly reveals you cannot be the biological father, your attorney will argue that the signature was based entirely on a material mistake regarding biological reality.

How Much Does it Cost in Washington?

Formal litigation in a Superior Court is significantly more expensive than filing administrative paperwork.

How Long Does the Process Take?

Once you are outside the 60-day window, undoing the VAP takes time. Drafting the petition, serving the other party, scheduling a hearing, and waiting for certified DNA lab results generally takes between 4 to 9 months, depending on how crowded the local Superior Court docket is and whether the mother aggressively contests the lawsuit.
