Child Custody Laws in Texas for Unmarried Parents

Under Texas child custody laws for unmarried parents, the mother is automatically the sole legal parent at birth, and the father has no enforceable rights to custody, visitation, or decision-making until paternity is legally established.¹ Once paternity is on the record, Texas treats unmarried parents the same as divorced ones: a court can assign conservatorship, set a possession schedule, and order child support under the same statutes that govern any other family.

Establishing Paternity Comes First

Texas offers two paths to legal fatherhood under the Uniform Parentage Act.² The faster route is a voluntary Acknowledgment of Paternity signed by both parents. Hospitals routinely offer the form at delivery, and parents can also file one later through the Texas Vital Statistics Unit or a local child support office. A signed and processed acknowledgment gives the father the same legal standing he would have had if the parents were married when the child was born.

Sign carefully. Either parent can rescind an Acknowledgment of Paternity within 60 days, but after that window closes, undoing it requires a court case and proof of fraud, duress, or a material mistake of fact.³

When the parents don’t agree, either one can file a paternity suit. The court typically orders DNA testing, and a positive result produces a decree naming the man as the legal father. There is no deadline for filing when the child has no presumed, acknowledged, or adjudicated father, so a father can still bring the case after the child is an adult.³ Court-admissible DNA tests generally run between $45 and $500, and the judge can order one party to pay.

Paternity also opens doors that have nothing to do with custody. A child with a legally recognized father can receive Social Security survivor benefits if the father dies, provided the child is unmarried and under 18 (or 19 if still in school full time).⁴ The child can inherit without a will, go on the father’s health insurance, and qualify for veterans’ benefits when applicable.

What Custody Is Called in Texas

Texas doesn’t use the word “custody” in its family code. The legal relationship between parent and child is called conservatorship, and Chapter 153 of the Texas Family Code sets the rules.⁵ Every decision about conservatorship, possession, and access turns on one standard: the best interest of the child.

Joint Managing Conservatorship

Texas law presumes both parents should be joint managing conservators. That presumption falls apart when there’s a history of family violence between the parents.⁵ Joint managing conservatorship is not a 50/50 time split. It means the parents share the big decisions about education, medical care, and religious upbringing. One parent’s home is still designated as the child’s primary residence, and the court can put a geographic restriction on where that parent lives.

Sole Managing and Possessory Conservatorship

When shared decision-making would be dangerous or impractical because of family violence, substance abuse, or similar concerns, the court can name one parent sole managing conservator. That parent decides where the child lives, what school the child attends, and what medical care the child receives. The other parent is usually named a possessory conservator, which preserves scheduled time with the child and access to school and medical records but strips out authority on the major decisions.⁵ Judges rarely cut a parent off from any access at all; a possessory conservator normally still gets a visitation schedule unless the judge finds contact would endanger the child.

Possession Schedules: When Each Parent Has the Child

Physical time is set by a possession and access order. For children age three and older, Texas law presumes the Standard Possession Order is in the child’s best interest. For children under three, the court builds an individualized schedule that expands the noncustodial parent’s time as the child grows.

Standard Possession Order

When the parents live within 100 miles of each other, the noncustodial parent gets the child on the first, third, and fifth weekends of each month, a few hours on Thursday evenings, alternating holidays, and an extended stretch each summer.⁵ Beyond 100 miles, the schedule drops to one weekend a month but adds more summer time and the whole of spring break.

Expanded Standard Possession Order

The Expanded Standard Possession Order adds overnight time. Thursday possession turns into an overnight stay instead of ending the same evening, and weekend possession starts at school dismissal on Friday instead of 6 p.m. Parents can also agree to a fully custom schedule as long as the court finds it consistent with the child’s best interest.

Enforcing the Schedule

A signed order is not a suggestion. When one parent blocks the other’s scheduled time, the denied parent can file a motion for enforcement. Judges can hold the violating parent in contempt, with penalties up to fines and jail. Keep a dated log of denied visits and the communications around them; it makes enforcement far easier.

Child Support

Texas child support runs on percentage guidelines applied to the paying parent’s monthly net resources. The court starts with all income (wages, self-employment, investment income, retirement) and subtracts Social Security taxes, federal income tax figured as if the parent were single with one exemption and the standard deduction, union dues, and the cost of the child’s health insurance.⁶

The guideline percentages:

One child: 20% of net resources
Two children: 25%
Three children: 30%
Four children: 35%
Five or more children: 40%

The percentages apply to the first $11,700 per month in net resources.⁷ Income above that cap can generate additional support if the child’s proven needs justify it, but there’s no automatic formula for the excess. The cap is adjusted periodically, so check the current figure before filing.

The court must also order medical and dental coverage. If the paying parent has employer or organization coverage available at reasonable cost (no more than 9% of annual resources), the child goes on that plan. If not, the court looks to the other parent’s employer coverage, and if neither is available or affordable, the paying parent owes cash medical support instead.⁶

When a parent doesn’t pay, Texas has real teeth. The most common tool is wage withholding, where the Attorney General’s office directs the employer to deduct support from each paycheck before the parent sees it.⁸ The state can also suspend driver’s, professional, hunting, and fishing licenses, place liens on property, and, for willful nonpayment, ask a court to hold the parent in contempt and jail them.

Filing a Suit Affecting the Parent-Child Relationship

The case that puts conservatorship, possession, and support in a signed order is called a Suit Affecting the Parent-Child Relationship, or SAPCR. Either parent can file. An unmarried father should have paternity established before, or at the same time as, this filing.

A Texas court has jurisdiction if the child has lived in Texas for the six consecutive months before filing, or since birth if the child is younger than six months. The petition goes to the district clerk in the county where the child lives, along with a filing fee that varies by county. The other parent has to be formally served with the papers, usually by a constable or private process server. If cost is a barrier, you can file an affidavit of inability to pay and ask the court to waive fees.

If the parents agree on terms, they can submit an agreed order. If they don’t, the case moves to mediation, then trial if mediation fails. At the final hearing, the judge confirms the terms serve the child’s best interest and signs the order, which is enforceable the moment it’s signed.

Changing the Order Later

Custody orders can be modified when circumstances materially and substantially change after the order was signed and the proposed change is in the child’s best interest. Judges look at things like a parent relocating, the child’s needs changing, work schedules shifting significantly, or one parent creating an unsafe environment.

Two other grounds don’t require proving changed circumstances. A child who is at least 12 can tell the judge in chambers which parent they’d prefer to designate the primary residence. And if the parent with primary residence has voluntarily handed off day-to-day care to someone else for at least six months, the other parent can seek modification on that basis alone. Military deployment doesn’t count as voluntary relinquishment.

Who Claims the Child on Taxes

The IRS default is straightforward: the custodial parent, meaning the parent the child lived with for the greater number of nights during the year, claims the child.⁹ When nights are equal, the parent with the higher adjusted gross income wins the tiebreaker.

The custodial parent can transfer the claim to the noncustodial parent by signing IRS Form 8332, which the noncustodial parent then attaches to their return. The release can cover one year or several, and the custodial parent can revoke it, though revocation only takes effect the next tax year. Releasing the dependency claim moves the child tax credit (up to $2,200 per child under 17, indexed for inflation starting in 2026) but does not transfer head-of-household filing status or the earned income tax credit, which stay with the custodial parent regardless.⁹ Writing the dependency question into the custody order (alternating years, or tying it to support compliance) heads off yearly fights.

Moves Across State Lines and Military Deployment

Relocation and deployment sit on top of Texas law under two federal frameworks. The Uniform Child Custody Jurisdiction and Enforcement Act, adopted in every state, makes the child’s “home state” (where the child has lived for the last six consecutive months) the court with priority to make initial custody decisions. Once a Texas court issues an order, Texas keeps authority to modify it as long as at least one parent or the child still lives in Texas. Another state generally cannot modify a Texas order unless Texas loses jurisdiction or declines to exercise it. The federal Parental Kidnapping Prevention Act reinforces this by requiring every state to honor and enforce another state’s custody order when the original court had proper jurisdiction and the parties got notice and a chance to be heard.¹⁰

Active-duty service members with a pending custody case get protection under the Servicemembers Civil Relief Act. If military duties keep the parent from appearing, the court must grant at least a 90-day postponement, and the judge can extend it for another 90 days.¹¹ Texas law separately bars courts from treating a deployment as a voluntary surrender of custody, so a service member’s rights survive the assignment.
