PATERNITY AND PARENTAGE ACTION IN WASHINGTON STATE: WHY IT IS IMPORTANT TO ESTABLISH PATERNITY

Paternity by definition means the state of being the father of a particular child. From a legal perspective, paternity refers to the legal relationship between a father and his child. A biological father is not necessarily a legal father. It is the process of “establishing paternity” that then establishes the legal relationship and associated rights and obligations of the legal father.

Washington state law acknowledges same-sex marriages and domestic partnerships with equality. The statute language speaks of parentage more broadly and gender neutral, rather than assuming a male father.

Establishing Parentage or Paternity:

Parentage in Washington State can be established by presumption, acknowledgement (voluntary), or through a parentage action in court (involuntary).

*Presumption:

If parents are married or in a domestic partnership when the child is born, parentage is presumed and automatically established. The person who gives birth is one legal parent and the spouse or domestic partner is presumed as the second legal parent. The presumed parents are listed on the birth certificate and automatically have legal parental rights and obligations.

When a child is born and the parents are not married or in a domestic partnership, the legal father or second parent is not presumed and parentage or paternity must be established in order to determine a legal relationship between the second parent and the child. Until paternity is established, the child does not have a legal father or second parent.

*Acknowledgement:

Unmarried parents may jointly agree to identify the stated biological father as the acknowledged father by signing an “acknowledgement of paternity”, which establishes legal paternity of a child. (RCW 26.26.300). Both parents must sign the acknowledgment and it must be done with a notary and properly filed with the state. This is often done at the hospital when the child is born. This method is considered “voluntary” since there is no dispute over parentage.

*Parentage Action:

When a voluntary agreement cannot be reached, Washington state law permits interested parties to file a parentage action in state court to make a legal determination about a child’s parents or paternity. This method is referred to as “involuntary” because someone is disputing paternity, which is why it becomes a court issue.

For example, if an unmarried father is attempting to establish paternity and the mother does not cooperate, court adjudication may become necessary. The father may file a parentage action, seeking the court to establish legal paternity. The court may need to order genetic testing to confirm the unmarried father’s paternity. If the court issues a parentage order, the man seeking to establish paternity becomes the adjudicated legal father.

Benefits of Establishing Parentage or Paternity:

There are many reasons that make it beneficial to establish a child’s legal parentage, legally, practically, and emotionally. Here are some of the reasons why legal establishment of parentage or paternity can be advantageous to all involved:
