How to dissestablish paternity after 10yrs of Lying?
My husband just found out through a DNA test that his 10yr old daughter from his previous marriage, is not biologically his. He had custody of his daughter for the last 5 yrs and recently in March gave her back to the mother because she wanted to live there, but now the DNA test results have made him want to disestablish parentage because he feels it has all been an attempt by the mother to use him for financial gain for the last 11 yrs. She never told him there was even a possibility of another father when she got pregnant and then the married when the child was 1yr old and divorce when she was 3yrs, it was through this divorce we believe that paternity was established because it was not done at the hospital when the child was born. We live in WA state and it looks like there is a 2 yr window to dissestablish paternity after it is done. However is there a way to prove fraud or perjury by the mother for signing the paternity affidavit declaring him as the father when she has now admitted to knowing this was possible and that she had spoke with an attorney about getting a DNA test done a few years back to attempt getting the child back from him, when he had custody? Will the court allow the dissestablishment if the mother signs a joinder in the petition and agrees to the order? Hopefully someone can help with this... Lawyers only please...
