Washington Petition to Withdraw (Rescind) Paternity Acknowledgment / Denial of Paternity is a legal process used to ask a court to withdraw a previously signed acknowledgment or denial of paternity. It is an alternative to filing a paternity action and can take place after a paternity action has already been settled. There are two types of Washington Petition to Withdraw (Rescind) Paternity Acknowledgment / Denial of Paternity — an “acknowledgment” and a “denial”. A petition to withdraw an acknowledgment requires the person who signed the acknowledgment to prove that the acknowledgment was signed as a result of fraud, duress, or mistake of fact. A petition to withdraw a denial requires the person who signed the denial to prove that the denial was signed as a result of fraud, duress, or mistake of fact. Both types of petitions must be filed in the court in the county where the paternity acknowledgment or denial was signed. The petitioner must provide evidence in order to prove the fraud, duress, or mistake of fact.
