Unmarried Father’s Rights in Texas: Establishing Paternity and Getting a Court Order

What this guide covers

If you are an unmarried father in Texas and the other parent is refusing to let you see your children, you have legal options. But the first step is not filing for conservatorship — it is establishing paternity. Without a legal determination that you are the father, you have no enforceable right to possession and access, no right to make decisions about your children, and no standing to ask a court for help.

This guide walks through how to legally establish paternity in Texas, how to file for conservatorship and possession and access once paternity is established, what forms you need, and where to get free or low-cost legal help.

Why paternity matters

In Texas, if the parents were never married, the mother is the sole managing conservator by default. The father has no legal rights to the child until paternity is established — either voluntarily or by court order. This means:

• The mother is not required to let the father see the children
• The father cannot request medical records, school information, or birth certificates
• The father cannot make legal decisions about the children
• No court can enforce possession and access until paternity is legally established

Establishing paternity changes this. Once the court recognizes you as the legal father, you can file for conservatorship and a possession order that gives you enforceable time with your children.

Two ways to establish paternity in Texas

Option 1: Acknowledgment of Paternity (AOP)

An Acknowledgment of Paternity (AOP) is a voluntary, signed document where both the mother and father agree that the man is the biological father. It is usually offered at the hospital when the child is born, but it can be signed at any time through the Texas Vital Statistics Unit (DSHS) or a certified entity.

If both parents agree on who the father is, the AOP is the fastest and simplest path. Once filed with DSHS and the 60-day rescission period passes, it has the same legal effect as a court order establishing paternity (Texas Family Code § 160.305).

Option 2: File a Petition to Adjudicate Parentage

If the mother will not cooperate with an AOP, you can file a Petition to Adjudicate Parentage (form FM-Pat-100) in the district court of the county where the child lives. This asks the court to determine paternity. Under Texas Family Code § 160.602, a man alleging himself to be the father of a child may file this petition at any time.

The court can order genetic (DNA) testing under § 160.502. If the results show a 99% or greater probability of paternity, the man is presumed to be the father (rebuttable presumption under § 160.505). The court then enters an order adjudicating parentage, which legally establishes the father-child relationship.

Using the Texas Attorney General's office

The Texas Office of the Attorney General (OAG) Child Support Division can help establish paternity and set up child support at no cost. You can apply online at childsupport.oag.state.tx.us or call 1-800-252-8014.

When the OAG opens a case, they handle paternity establishment (including arranging DNA testing), establish child support orders, and can also establish conservatorship and possession orders. This is a free service. However, the OAG's primary focus is collecting child support, not advocating for one parent's conservatorship preferences. If your main goal is getting meaningful possession time, filing your own SAPCR petition may give you more control over the outcome.

What forms do you need?

Texas does not use a unified form numbering system like California. Forms come from TexasLawHelp.org and are organized by case type. Here are the forms for establishing paternity and filing for conservatorship:

Step-by-step process

Step 1: Establish paternity

If the other parent will cooperate, sign an Acknowledgment of Paternity (AOP) through DSHS. If the other parent refuses, file a Petition to Adjudicate Parentage (FM-Pat-100) in the district court of the county where the child resides. The court can order DNA testing at either party's request (§ 160.502).

Step 2: File a SAPCR petition

File a Petition in Suit Affecting the Parent-Child Relationship (FM-SAPCR-100). This is the case that asks the court to establish conservatorship, possession and access, and child support. You can include a paternity allegation in the same petition if paternity has not yet been adjudicated. File in the district court of the county where the child has lived for the last six months (§ 103.001).

Step 3: Serve the other parent

After filing, the district clerk issues a Citation. The citation and a copy of the petition must be personally served on the other parent by a constable, sheriff, or private process server. You cannot serve the papers yourself. The other parent then has until 10:00 a.m. on the first Monday after 20 days from the date of service to file an answer.

Step 4: Request temporary orders (if needed)

If you need immediate access to your children while the case is pending, you can file a motion for temporary orders. The court can grant temporary conservatorship and a temporary possession schedule. In urgent situations — such as a parent refusing all access — the court can hold a temporary orders hearing within a few weeks of filing.

Step 5: Attend mediation

Most Texas family courts require mediation before a trial. A neutral mediator helps both parents negotiate a parenting plan. If you reach an agreement, it becomes a binding Mediated Settlement Agreement (MSA) under § 153.0071. If mediation fails, the case proceeds to a hearing where a judge decides.

Step 6: Final hearing and court order

At the final hearing, the judge reviews the evidence and enters an Order in SAPCR (FM-SAPCR-200). This order establishes conservatorship, possession and access schedules, child support, and medical support. If the other parent does not appear, you can request a default judgment.

What does the court consider?

Texas courts apply the best interest of the child standard using factors from Holley v. Adams, 544 S.W.2d 367 (Tex. 1976):

• The child's desires (depending on age)
• Each parent's emotional and physical needs now and in the future
• Emotional and physical danger to the child
• The parenting abilities of each parent
• The stability of each parent's home
• Each parent's plans for the child
• Acts or omissions that indicate the parent-child relationship is inappropriate

Texas law presumes that joint managing conservatorship (JMC) is in the best interest of the child (§ 153.131). This means both parents share rights and duties. JMC does not automatically mean equal possession time, but the court will set a schedule that serves the child's best interest.

What about false accusations?

If the other parent has made false accusations of violence or abuse — for example, calling the police and making false statements — this can affect your case in both directions. A protective order or family violence finding can restrict your access to your children and create a presumption against joint managing conservatorship (§ 153.004).

However, false accusations can also work against the person making them. Texas courts consider a parent's willingness to foster a positive relationship with the other parent. Documented false reports, dismissed protective orders, and police reports showing no charges were filed can all be presented as evidence. Keep records of every incident, including police report numbers, officer names, and outcomes.

How much does this cost?

How long does this take?

• AOP: Immediate once both parents sign. Takes legal effect after the 60-day rescission period.
• Temporary orders hearing: 2–6 weeks after filing (varies by county and court availability)
• DNA test results: 2–4 weeks from the test date
• Full case (filing to final order): 3–9 months if contested, faster if both parties agree
• Default judgment: If the other parent does not respond or appear, a default order can be entered after the answer deadline passes
