How to Establish Legal Parentage.
Legal parentage can affect custody, parenting time, support, inheritance, benefits, and access to records. Procedures and terminology vary by state.
Check whether parentage already exists
Review birth records, acknowledgment forms, marriage presumptions, adoption records, and prior court or agency orders.
Understand voluntary acknowledgment
Many states use signed acknowledgment forms, but rescission and challenge deadlines may be short. Read the form and obtain advice before signing if there is uncertainty.
Court establishment
A parent, child-support agency, or another authorized person may be able to file a parentage case. Service, genetic testing, and hearings may be required.
Parentage is not the whole parenting plan
After parentage is established, separate orders may still be needed for custody, parenting time, decision-making, transportation, and support.
Do not use informal tests as a court order
Consumer tests may not satisfy chain-of-custody or court requirements. Follow the testing process authorized by the court or agency.
Act promptly
Deadlines and presumptions can affect options. Contact your state court self-help center, child-support agency, or a licensed attorney.
