How is Custody Determined for Unmarried Parents in Texas?

Seeing both names on a birth certificate can make parents feel like child custody has already been settled. Then a disagreement happens. One parent wants a set schedule. The other parent refuses a visit. A school, doctor, or daycare asks who has authority to make decisions. Suddenly, the paperwork that felt official does not answer the question that matters most.

In Texas, a birth certificate is not the same as a custody order. For unmarried parents, legal paternity and court-ordered custody are separate issues. An Acknowledgment of Paternity can establish legal fatherhood, but it does not set a parenting schedule, divide decision-making authority, or create an enforceable visitation order by itself. When parents need clear rules, they usually need a court order through a Suit Affecting the Parent-Child Relationship.

At The Law Office of Raul V. Treviño, we help parents in San Antonio, Austin, Dallas, and Houston understand what Texas law requires before conflict grows. We handle paternity, conservatorship, and Suit Affecting the Parent-Child Relationship matters in English and Spanish, and initial consultations are conducted with Raul directly.

Who Has Custody if Both Parents Are on the Birth Certificate but Are Not Married in Texas

If both parents are on the birth certificate but are not married in Texas, the answer depends on whether the father is a legal parent and whether a court order already exists. A birth certificate by itself does not create a custody order, possession schedule, or child support order.

For unmarried parents, legal paternity can be established through an effective Acknowledgment of Paternity, a court order, or another legally recognized basis under Texas law. Once legal paternity is established, the father has parental rights and duties, but that still does not mean there is a set visitation schedule or court-enforceable custody arrangement.

Parents usually need a Suit Affecting the Parent-Child Relationship to turn legal parentage into clear orders for:

• Conservatorship.
• Possession and access.
• Child support.
• Medical support.
• Dental support.

If paternity has not been legally established, the biological father does not yet have enforceable parental rights under Texas law. In that situation, the mother is typically the only legally recognized parent unless and until paternity is established or a court orders otherwise.

What Texas Law Says About Custody and Conservatorship for Unmarried Parents

Texas courts use the terms conservatorship and possession and access instead of custody and visitation. Conservatorship covers legal rights and duties, including major decisions about the child’s care. Possession and access covers when each parent spends time with the child.

For unmarried parents, the court first needs to determine who the child’s legal parents are. If paternity has already been established through an effective Acknowledgment of Paternity or court order, a SAPCR can ask the court to set parenting and support terms. If paternity has not been established, a paternity case can ask the court to name the child’s legal father and enter those orders at the same time.

A court order can address the following:

• Which parent has the right to determine the child’s primary residence.
• How education, medical care, and other major decisions will be handled.
• When each parent has possession of and access to the child.
• How child support, medical support, and dental support will be paid.
• Whether any safety, travel, communication, or geographic restrictions should apply.

Texas courts generally presume that appointing both parents as joint managing conservators is in the child’s best interest, but that presumption can be overcome. Family violence, child neglect, safety concerns, a parent’s absence, and other facts may affect how the court allocates parental rights and duties.

Conservatorship vs. Possession and Access

Conservatorship is the legal relationship between a parent and child. It controls rights and duties, including who can make certain decisions for the child.

Possession and access is the parenting schedule. It controls when the child is with each parent.

These two issues often overlap, but they are not the same. A parent may be named a conservator and still need a clear possession order before visitation can be enforced. That is why unmarried parents often need more than proof of paternity. They need a court order that explains how parenting will actually work.

How an Unmarried Father Establishes Paternity in Texas

Texas law recognizes several ways to establish the father-child relationship. For many unmarried parents, the most common paths are:

• Acknowledgment of Paternity. Both parents may sign an Acknowledgment of Paternity with an AOP-certified entity. Once the completed AOP is filed and effective, the father becomes the child’s legal father.
• Court order. If parents disagree about paternity, or if an AOP is not available, a parent or another authorized person may file a paternity case. The court may order genetic testing and enter an order naming the child’s legal father.
• Office of the Attorney General case. The Office of the Attorney General may help establish paternity as part of a child support case.

A presumed father can make the process more complicated. In many cases, a proceeding to adjudicate parentage when a child has a presumed father must be filed by the child’s fourth birthday.

The Acknowledgment of Paternity Process

An Acknowledgment of Paternity is often signed at the hospital after birth, but parents may also complete it later through an AOP-certified entity. The document takes effect once it is properly completed, signed, and filed.

Parents should understand what an AOP does and what it does not do. An AOP can establish legal paternity. It does not create a court-ordered custody schedule, decide who has the right to choose the child’s residence, or set child support.

A parent who signs an AOP may have a limited time to rescind it. After that period ends, a challenge is generally limited to specific legal grounds, such as fraud, duress, or material mistake of fact. Parents who are unsure whether an AOP was signed, filed, or challenged should get legal guidance before assuming what rights exist.

Filing a Suit Affecting the Parent-Child Relationship After Paternity Is Established

Establishing paternity does not, by itself, create a parenting schedule. A Suit Affecting the Parent-Child Relationship is the court case Texas parents use to ask for custody, visitation, child support, medical support, and dental support orders.

A SAPCR can ask the court to decide:

• Whether one or both parents will be managing conservators.
• Which parent has the right to determine the child’s primary residence.
• How major decisions about education, medical care, and other issues will be handled.
• What possession and access schedule will apply.
• How child support, medical support, and dental support will be paid.

In Bexar County, SAPCR cases are handled through the family courts. In Travis County, family law cases are handled through the district courts. Local rules, filing requirements, standing orders, and court procedures can affect how the case moves forward, especially when parents need short-term rules while the case is pending.

Frequently Asked Questions About Custody for Unmarried Parents in Texas

Does a Father Have Rights if He Is on the Birth Certificate in Texas?

A father’s name on the birth certificate does not create a custody order by itself. If an effective Acknowledgment of Paternity has been filed, the father is the child’s legal father and has parental rights and duties. However, he may still need a SAPCR order to create an enforceable parenting schedule, decision-making rules, and support terms.

If paternity has not been legally established, the biological father usually needs an AOP or court order before he can assert parental rights.

Can an Unmarried Mother Move Out of Texas With the Child?

Relocation depends on whether paternity has been established and whether a court order limits where the child may live. If there is no court order, there may be no enforceable geographic restriction. However, relocation can create serious legal and practical problems, especially if the other parent later files a paternity case or SAPCR.

Once a SAPCR order is in place, it may include geographic restrictions, notice requirements, and other rules about the child’s residence. A parent considering a move should get legal guidance before relocating with the child.

How Long Do I Have to Establish Paternity in Texas?

When no presumed father exists, there may not be a strict deadline to establish paternity during the child’s life. When a presumed father exists, the deadline can be much shorter. In many cases, a proceeding involving a presumed father must be filed before the child turns four, unless a limited exception applies.

Because the deadline depends on the facts, parents should not rely on general information alone. A Texas family law attorney can review whether a presumed father exists, whether an AOP was signed, and what filing deadline may apply.

What Is a SAPCR and Do I Need One?

A Suit Affecting the Parent-Child Relationship is a Texas civil case involving a child. For unmarried parents, a SAPCR can establish orders for conservatorship, possession and access, child support, medical support, and dental support.

You may need a SAPCR if you want a parenting schedule, enforceable visitation rights, support orders, or clear rules about who makes decisions for the child. Establishing paternity alone may not be enough to answer those questions.

Can Both Parents Share Custody in Texas if They Were Never Married?

Yes. Unmarried parents can share custody in Texas once legal parentage has been established and the court enters appropriate orders. Texas courts often appoint both parents as joint managing conservators, but the court still looks at the child’s best interest.

Joint managing conservatorship does not always mean equal time. The order may still name one parent with the right to determine the child’s primary residence and set a specific possession schedule for the other parent.
