What If the Mother Refuses a Paternity Test?

For a father trying to establish his rights, a refusal to cooperate with genetic testing can feel like a locked door. In Washington, it is not. The court has the authority to order testing, and a refusal has consequences. The Law Office of Chad Foster helps Snohomish County clients with parentage matters.

You Are Not Stuck

If you have a reasonable basis to believe you are a child's father and the mother will not agree to a paternity test, you do not have to give up. Washington law lets you ask a court to order genetic testing as part of a parentage case, and when the legal requirements are met, the court is directed to order it. A parent cannot simply block the process by declining to participate. The path runs through the court, not through the other parent's permission, and that is exactly what protects a father who is being shut out.

How the Court Gets Involved

Genetic testing outside of a mutual agreement happens inside a legal proceeding. You start by opening a case to adjudicate parentage, which is the formal court process for determining who a child's legal parents are. Within that case, you request an order for genetic testing. This is not an informal request. It is a specific legal step, and Washington's Uniform Parentage Act sets out exactly what has to accompany it. For related guidance, see How Much Does a Paternity Test Cost.

Under RCW 26.26A.310, in a proceeding under the parentage chapter to determine parentage, the court shall order the child and any other individual to submit to genetic testing if the request is supported by the sworn statement of a party. For someone trying to establish that he is the father, the sworn statement must allege a reasonable possibility that he is the child's genetic parent. The word "shall" is significant. When a party provides that sworn statement and the reasonable possibility is shown, the statute directs the court to order the testing rather than leaving it to pure discretion. A person who denies being the parent can use the same mechanism from the other direction, by swearing to facts showing a reasonable possibility that he is not the genetic parent.

What "Reasonable Possibility" Means

The threshold is a reasonable possibility, not absolute certainty. You do not need proof already in hand, because the whole point of the test is to obtain that proof. What you do need is a sworn statement, meaning a statement made under oath and penalty of perjury, laying out facts that make it reasonably possible you are the father. A sexual relationship with the mother during the likely time of conception is the kind of fact that typically supports such a statement. The requirement exists to keep people from demanding tests on baseless whims, while still keeping the door open for anyone with a genuine claim.

When the Mother Will Not Cooperate

Here is the reassuring part for a father facing an uncooperative mother. The statute anticipates exactly this situation. Under RCW 26.26A.310, genetic testing of the woman who gave birth is not a condition for testing the child and the man whose parentage is being determined. If the mother is unavailable or declines to submit to genetic testing, the court may order genetic testing of the child and each individual whose parentage is being adjudicated.

In plain terms, the mother's own sample is not required to run a valid comparison. Modern genetic testing can establish parentage by comparing the child's DNA with the alleged father's, so the mother refusing her own test does not stop the process. The court can still order the child and the alleged father to be tested, and that comparison can answer the question.

The Order Has Teeth

A court order to submit to testing is not a polite suggestion. RCW 26.26A.310 states that an order under that section for genetic testing is enforceable by contempt. Contempt of court is a serious matter. A person who defies a valid testing order can face sanctions the court chooses to impose to compel compliance. This enforcement power is what gives the order real force. A parent cannot simply ignore it without risk.

Courts also have tools to move a stalled case forward. When a party refuses to comply with a lawful order in a parentage case, the refusal itself can carry weight, and judges have ways to keep the case from grinding to a halt because one side will not participate. The overall design of the law is to make sure that a child's parentage can be determined even when one adult is unwilling to cooperate.

A Note on Limits and Fairness

The testing rule is powerful, but it is not unlimited. The same statute gives courts the ability to deny genetic testing in certain circumstances, particularly where a child already has a presumed, acknowledged, or adjudicated parent and ordering a test would not serve the child. In those cases, the court weighs statutory factors, including the child's existing relationships and best interest, before deciding whether testing goes forward. The law also flatly prohibits ordering testing before birth. These guardrails exist so that the process establishes truth without needlessly disrupting a child's settled life.

Getting the Sworn Statement and the Case Right

The refusal of a paternity test can feel like the end of the road, but under Washington law it usually is not. The keys are opening the right kind of proceeding, presenting a proper sworn statement showing a reasonable possibility of parentage, and understanding that the resulting order carries the enforcement power of the court behind it. Getting the sworn statement right and framing the request correctly can be the difference between a smooth order and a stalled case.
