Washington, MO - DNA Testing

Establishing Paternity in Washington, MO

Establishing paternity means determining a child's biological father and establishing him as the child's legal father. Unmarried parents in Washington, MO must establish paternity by signing an Affidavit Acknowledging Paternity or by a court order. An Affidavit Acknowledging Paternity can be signed at the hospital when the child is born or later at the Bureau of Vital Records, located at 405 Jefferson St 1st floor in Washington. If establishing paternity in court, the judge may order DNA testing and use the results as evidence when determining whether the man shall become the child's legal father.

Benefits of Establishing Paternity

Establishing paternity benefits the mother, the father, and especially the child. Having a legal father provides the child with a sense of identity, medical history, medical and life insurance, financial support from both parents, social security, veteran's benefits, and other available benefits. Establishing paternity also allows the father to seek visitation and custody rights and provides the mother with financial support. Most importantly, it allows the child to develop relationships with both parents. Until the parents establish paternity, fathers do not have decision-making rights as parents, including decisions about healthcare and education.

Proving Paternity for Child Custody Purposes in Washington, MO

If questioning paternity, parents can use DNA testing, also called paternity testing, to determine the child's biological father. DNA test samples are taken from a cheek swab and sent to a lab for testing. In Washington, MO, if a DNA test shows at least a 98% probability that a man is the child's biological father, he's presumed the child's father under state law. Although a DNA test proves paternity, it does not legally establish a biological father as a legal father. The parents must sign the Affidavit Acknowledging Paternity or get a court order to establish paternity.
