King residents may wish to know about the laws surrounding establishing paternity in Washington. There are a few different methods, with each one being appropriate depending on certain factors.
Under the laws of the State of Washington, there are four ways for a parent to establish paternity of their child. If the biological father marries the child's mother prior to the birth of the child, then there is a presumption of paternity. This may also apply when the couple is in a registered domestic partnership. The father may also sign an official form called a Paternity Acknowledgement which will then make him the legal father of the child. In cases where there is already a presumed father, that man will have to sign a Presumed Parent's Denial of Paternity in order for the actual father's Paternity Acknowledgement to be valid.
