In South Carolina, unmarried parents can establish paternity (legal fatherhood) in three main ways: by signing a voluntary acknowledgment of paternity, through DNA testing, or by filing a paternity action in family court. Establishing paternity gives a child legal ties to both parents and opens the door to custody, visitation, child support, inheritance, and access to benefits. It also gives an unmarried father legal standing to seek custody or visitation in court.
When you’re not married to your child’s other parent, questions about paternity can feel deeply personal. Maybe you’re a mother who needs support for your child, or a father who wants to be a real part of your child’s life. Either way, the legal steps aren’t always clear. Here’s what South Carolina paternity laws mean for you, in plain English.

Why Does Establishing Paternity Matter for Unmarried Parents?
Establishing paternity matters because, until it’s legally settled, an unmarried father has no automatic legal rights to his child, and the child may miss out on meaningful support and benefits. In South Carolina, when parents aren’t married, custody of the child rests solely with the mother unless she has relinquished her rights, and only after paternity is acknowledged or adjudicated can the father petition the court for rights of visitation or custody (S.C. Code Ann. § 63-17-20).
For the child, legal paternity can mean support from both parents, eligibility for a father’s health insurance, Social Security, or veterans’ benefits, access to family medical history, and inheritance rights. For parents, it creates clarity and a foundation for a genuine father-child relationship. This isn’t about taking sides. It’s about protecting the child and giving both parents a fair, defined role.

How Do You Establish Paternity in South Carolina?
There are three main paths, and the right one depends largely on whether both parents agree.
Voluntary acknowledgment of paternity
If both parents agree on who the father is, the simplest route is a voluntary acknowledgment of paternity. This is a sworn document, often signed at the hospital around the time of birth or later through the state’s child support services. Under South Carolina law, a signed acknowledgment creates a legal finding of paternity, subject to the right of any signatory to rescind the acknowledgment within the earlier of 60 days or the date of a related administrative or judicial proceeding (S.C. Code Ann. § 63-17-50). After that window, it may be challenged in court only based on fraud, duress, or material mistake of fact, with the burden of proof on the challenger. Because the effects are lasting, the person acknowledging paternity must be allowed to seek legal advice before signing.
DNA (genetic) testing
When fatherhood is in question, a paternity test provides the answer. Under South Carolina law, a statistical probability of paternity of 95% or higher creates a rebuttable presumption of the putative father’s paternity (S.C. Code Ann. § 63-17-60). Parents can arrange a paternity test on their own, through DSS Child Support Services, or by court order.
A court action in family court
If the parents don’t agree, either parent can file a paternity action in South Carolina family court. In a contested case, the child and all parties, upon the request of any party, must be ordered by the court to submit to genetic testing to determine paternity. Once the judge enters an order, paternity is legally established, which clears the way to address custody, visitation, and support.
What Rights and Responsibilities Follow for the Father?
Once paternity is established, a father gains legal rights and assumes legal responsibilities. The rights he will obtain include, he may petition the court for visitation or custody rights and have a voice in major decisions about the child’s upbringing. On the responsibility side, he shares a legal duty to support the child financially.
These two sides go hand in hand. Establishing paternity is often the step that enables a mother to pursue child support and the step that gives a father the standing to build a lasting relationship with his child.

How Does Paternity Connect to Custody and Child Support?
Paternity is the legal foundation that must exist before a South Carolina court will order custody, visitation, or child support involving an unmarried father.
For custody and visitation, the court uses the best interests of the child standard, with no automatic preference for either parent. The judge weighs each parent’s ability to care for the child, stability, and the child’s needs. For child support, South Carolina uses income-shares guidelines that consider both parents’ incomes, and state law provides that child support obligations begin on the date of conception.
Frequently Asked Questions About South Carolina Paternity Laws
How do I establish paternity if the other parent won’t cooperate?
You can file a paternity action in family court. In a contested case, the judge can order the child and both parties to submit to genetic testing at a party’s request. Once the results and other evidence are in, the court can establish paternity and then address custody and support.
Does signing the birth certificate establish paternity?
Signing the birth certificate is strong evidence, but it isn’t always the last word. Under South Carolina law, a birth certificate containing the signature of the mother and the putative father creates a rebuttable presumption of paternity, which means it can still be challenged. A properly signed voluntary acknowledgment gives you firmer legal footing.
Can a paternity acknowledgment be undone?
Sometimes. A signer can cancel a voluntary acknowledgment within the earlier of 60 days or the date of a related proceeding. After that, it can only be challenged for fraud, duress, or a material mistake of fact, and the person challenging it carries the burden of proof.
