When parents are not married, a father’s name on the birth certificate does not, by itself, give him the right to custody or parenting time, and it does not give the mother an enforceable order for child support. Those rights come from establishing paternity and then obtaining a court order, which are two separate steps that many parents assume happen on their own. If you are facing a paternity question in Columbia or Boone County, whether you are a father seeking time with your child or a mother seeking support, Gump, Faiella & Bugalski can help you establish parentage and the orders that go with it.
Missouri gives you more than one path to establish paternity. Parents can sign an Affidavit Acknowledging Paternity, the Family Support Division can open a case, or either parent can file a paternity action in court under Missouri’s Uniform Parentage Act. Which path fits depends on whether paternity is agreed or disputed, and whether custody and support need to be decided at the same time. The choice matters, because it shapes what actually gets decided and how quickly.
Our Columbia family law team handles paternity cases for both mothers and fathers in Boone County, from a straightforward acknowledgment to a contested action that also has to settle custody, parenting time, and support.
Establishing paternity is what creates the legal relationship between a father and a child. Until that relationship exists in the eyes of the law, a father has no automatic right to custody or parenting time, and a mother has no order she can enforce for support. Paternity is the gate that everything else passes through.
Once paternity is established, it opens up the things parents actually came for. A father gains standing to ask a court for custody and parenting time. A mother can obtain an enforceable child support order. The child gains the right to inherit, to claim benefits such as Social Security or veterans’ benefits through the father, and to a complete family medical history. These are not small things, and none of them are available until parentage is settled.
For married parents, the law generally assumes the husband is the father, so paternity is presumed. For unmarried parents, it has to be established, and how you do that is the subject of the rest of this page.
Missouri recognizes several ways to establish paternity. The right one depends on your situation and on whether the other parent agrees.
When the mother is married at the time the child is born, or the child is born within a defined period after a marriage ends, Missouri law presumes the husband is the legal father unless a court determines otherwise. Rebutting that presumption, or confirming that someone else is the biological father, generally requires a formal step such as a denial of paternity or a court action.
Unmarried parents who agree on paternity can sign an Affidavit Acknowledging Paternity, often at the hospital when the child is born, or later through the Department of Health and Senior Services. Signing places the father's name on the birth certificate and, under Missouri law, operates as a legal finding of paternity. It is the simplest path when parentage is not in dispute, but it comes with a time limit to change course, which the next section explains.
The Family Support Division can establish paternity and set child support through an administrative process, which is common when a child receives state benefits. Free genetic testing is available through the Division when it is requested before paternity is established. This route focuses on parentage and support and does not resolve custody or parenting time.
Either parent can file a paternity action in circuit court under Missouri's Uniform Parentage Act (RSMo Chapter 210). This is the path when paternity is disputed, when a father wants custody and parenting time and not just a name on a certificate, or when a mother needs custody and support decided together. In a court action, the judge can order genetic testing and can decide parentage, custody, parenting time, and support in the same case.
Because the routes lead to different places, choosing the right one at the start saves time and avoids having to open a second case later. An acknowledgment settles who the father is. It does not set a parenting schedule. A court action can settle all of it at once.

The Affidavit Acknowledging Paternity is powerful and easy to underestimate. Once signed by both parents, it operates as a legal finding of paternity under RSMo § 210.823, puts the father on the birth certificate, and creates a support obligation. It is not a formality, and it should not be signed casually.
Missouri gives a signer a limited window to undo it. Either parent may rescind the acknowledgment in writing within the earlier of sixty days from the date of the last signature, or the date of an administrative or judicial proceeding relating to the child in which the signer is a party. After that window closes, the acknowledgment can be challenged only by proving fraud, duress, or a material mistake of fact, and the person challenging it carries the burden. During a challenge, the legal obligations that come with the acknowledgment, including support, generally continue.
The practical caution is the one from the top of this page. Signing the affidavit establishes that a man is the legal father, but it does not, on its own, give him custody or parenting time, and it does not give the mother a support order she can take to court. Those still require a separate order. Signing is often the right move, but it should be a decision made with a clear understanding of what it does and does not do.
When paternity is genuinely in question, genetic testing usually resolves it. In a contested court case, either party can request testing, and the court can order it (RSMo § 210.828). The Family Support Division can arrange testing in its administrative cases, at no cost when requested before paternity is established. Missouri treats a test showing a high probability of paternity, at least 98 percent, as establishing that the man is the father.
Two points come up often. First, the test has to be done properly to be used in court. A court-recognized test follows a documented chain of custody, which is why an over-the-counter home kit is generally not enough on its own to establish or disprove paternity in a legal proceeding. Second, when a party refuses to cooperate with court-ordered testing, that refusal has consequences, and a court has tools to address it. If testing is a live issue in your case, it is worth getting the process right the first time.
This is the point that surprises the most people, so it is worth stating plainly. Establishing paternity answers the question of who the legal parents are. It does not answer who the child lives with, what the schedule looks like, or how much support gets paid. Those are separate questions, decided under their own rules.
Custody and parenting time are decided under Missouri’s best-interest standard in RSMo § 452.375, and the arrangement is written into a parenting plan under RSMo § 452.310. If you are a father, this is where your rights to time and decision-making are actually secured, and Missouri law does not give either parent a preference based on sex. If you are a mother, this is where a workable schedule and enforceable structure come from. Our parenting plans page explains what goes into that document and how to make it hold up.
Child support is calculated separately using Missouri’s Form 14. Once paternity is established, support can be ordered and enforced, and in a court paternity action the judge can address support in the same case rather than making you file again.
The efficient approach, in most contested situations, is to resolve parentage, custody, parenting time, and support together rather than establishing paternity and then starting over for everything that follows.
Missouri maintains a Putative Father Registry (RSMo § 192.016) for men who believe they may have fathered a child born outside of marriage. Registering is how an unmarried man preserves his right to receive notice of an adoption or a proceeding to terminate parental rights involving that child.
The registry matters most because of timing. There are strict deadlines tied to the child’s birth for registering and preserving the right to notice, and missing them can mean losing the chance to be heard before significant decisions are made. A man who believes he may be a father, and who wants a say if an adoption or termination is filed, should treat registration as time-sensitive and get advice quickly rather than assuming he will be notified automatically.
The most common paternity situation we see is not a dramatic dispute. It is a father who signed the acknowledgment at the hospital, believed that settled everything, and later discovered he had no order setting his time with his child. The acknowledgment made him the legal father. It never gave him a schedule, and without an order there was nothing to enforce when the relationship between the parents changed.
We see the mirror image just as often. A mother who has been the primary caregiver assumes support is in place because the father acknowledged the child, and then learns there is no support order to enforce. In both cases, the missing piece is the same. Parentage was established, but the orders that give it teeth were never entered.
What tends to work better is treating paternity as the first step rather than the whole job. When parentage, custody, parenting time, and support are addressed together, both parents leave with something enforceable and a clear picture of how things will actually work. That is the approach we take, whether we are representing the mother or the father.

There are several paths. Married parents are covered by a legal presumption that the husband is the father. Unmarried parents who agree can sign an Affidavit Acknowledging Paternity, which places the father on the birth certificate and operates as a legal finding of paternity. The Family Support Division can establish paternity and support administratively, often in cases involving state benefits. And either parent can file a paternity action in court under Missouri’s Uniform Parentage Act, where a judge can order genetic testing and decide parentage, custody, and support. The right path depends on whether paternity is agreed or disputed and whether custody and support need to be decided at the same time.
No. Signing the birth certificate through an Affidavit Acknowledging Paternity makes a man the legal father and creates a support obligation, but it does not by itself give him custody or a parenting schedule. Custody and parenting time are decided separately under the best-interest standard and written into a parenting plan. A father who wants enforceable time with his child needs a court order in addition to the acknowledgment.
Generally not in a way a court will enforce. Until paternity is established, an unmarried father usually has no enforceable right to custody or parenting time, which is why establishing paternity is the necessary first step. Once parentage is settled, a father can ask the court for a specific parenting schedule, and Missouri law does not give either parent a preference based on sex.
Only within a limited window. Either parent can rescind the acknowledgment in writing within the earlier of sixty days from the last signature or the start of a court or administrative proceeding about the child in which the signer is a party. After that, the acknowledgment can be set aside only by proving fraud, duress, or a material mistake of fact, and the person challenging it has the burden. Support and other obligations generally continue while a challenge is pending.
It depends on the path. When the Family Support Division handles a case, free genetic testing is available if it is requested before paternity is established. In a court action, the judge decides how the cost of testing is allocated between the parties. A test used in court has to follow a proper chain of custody, so an over-the-counter home test is generally not sufficient on its own for a legal proceeding.
A refusal to cooperate with court-ordered genetic testing has consequences. The court has authority to order testing and to address a party who will not comply. Refusing a test is not a way to avoid a paternity determination, and it often works against the person who refuses.
Paternity can generally be established throughout a child’s minority, so there is usually time to act. Some related deadlines are strict, however. The window to rescind an Affidavit Acknowledging Paternity is short, and the Putative Father Registry has deadlines tied to the child’s birth for preserving the right to notice of an adoption or termination. Because the timelines vary by situation, it is worth getting advice early rather than assuming you have unlimited time.
Establishing paternity is what makes a child support obligation enforceable against the father. Once parentage is settled, support is calculated using Missouri’s Form 14, which factors in both parents’ incomes, the parenting time arrangement, health insurance, child care, and other adjustments. In a court paternity action, the judge can set support in the same case, so parentage and support are resolved together.
Paternity is the foundation that custody, parenting time, and support are built on. Establishing it is often straightforward, but the orders that give it real effect are where the outcome is decided, and getting them right the first time matters for both parents.
