Child custody and parenting time

Parents who are not married

Signing a paternity form makes a father the legal parent. A custody order is a separate step.

Parents who are not married

  • Federal law requires every state to offer a simple way for unmarried parents to sign a form saying who the father is. It is called a voluntary acknowledgment of paternity. States must offer it at hospitals around the time of birth and at the state birth records office.
  • Before you sign, you must be told, out loud and in writing, about your other choices, the legal effects, and your rights and duties.
  • For unmarried parents, the father's name goes on the birth certificate only if both parents signed the acknowledgment, or a court or agency decided paternity.
  • A signed acknowledgment counts as a legal finding of paternity. A person who signed can cancel (rescind) it within 60 days, or earlier if there is a court or agency case about the child where that person is a party, whichever comes first.
  • After the 60 days, the acknowledgment can be challenged in court only for fraud, duress (being forced), or a material mistake of fact. The person challenging must prove it. Child support duties usually keep going during the challenge.
  • Every state must honor an acknowledgment signed in another state.
  • Signing the acknowledgment makes a father the legal parent. It does not by itself create a custody or parenting-time order. To get a schedule, a parent can ask the court. Rules differ by state.
  • If paternity is disputed, the state must order genetic tests when a party asks and gives a sworn statement.
  • Paternity is also the first step to child support. See RobinClaim's Child support section.
