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

A parent becomes a managing conservator only when a court appoints one (§ 153.005), and in deciding conservatorship and possession the court must consider the parents' qualifications without regard to sex or marital status (§ 153.003). The difference for unmarried parents is who counts as a legal parent. The mother-child relationship is established by giving birth. For an unmarried father, the father-child relationship is usually established by an unrebutted presumption of paternity, an effective Acknowledgment of Paternity, or a court adjudication (§ 160.201). Until paternity is established, this means:

  • The father has no legal right to possession of the children, so the mother is not required to let him see them
  • The father does not have a parent's rights, such as consenting to medical care or making decisions about the children's education (§ 151.001)
  • There is no possession schedule a court can enforce

Establishing paternity changes this. Once you are the legal father, you have the rights and duties of a parent (§ 151.001), but without a court order neither parent has an enforceable possession schedule. Filing for conservatorship and a possession order is what 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).

AOP requires cooperation

An AOP requires both parents to sign voluntarily. If the other parent refuses to sign or disputes paternity, you must use Option 2 and file a court petition.

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-Pat1-100) 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.

Combine paternity and conservatorship

You can establish paternity and request conservatorship in the same case. The SAPCR Petition (FM-SAPCR-100) includes a section for alleging paternity. This avoids filing two separate cases and saves time and money.

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-Pat1-100) 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).

Birth certificate requirement

As of September 1, 2025, HB 1973 requires the petitioner in a SAPCR to submit a certified copy of the child's birth certificate to the court. If unavailable or if it does not name both parents, the court may accept alternative proof such as medical records, school records, or religious records. The birth certificate is sealed and kept confidential by the court.

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.

Expanded Standard Possession Order

Since September 1, 2021, the Expanded Standard Possession Order (ESPO) is the statutory default when the non-primary parent lives 50 miles or less from the child's primary residence (§ 153.3171). The ESPO includes Thursday overnight and extends weekends through Monday morning drop-off when school resumes. The court does not order the expanded times if that parent declines them, if the court is restricting that parent's possession under § 153.004, or if the court finds they are not in 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.

Document everything

Save all text messages, voicemails, emails, and social media posts. Request copies of police reports. If false allegations have been made, this documentation is critical evidence for your case.

How much does this cost?

ItemCost
Filing fee (SAPCR or paternity petition)Varies by county; see the state's district court fee list and ask the district clerk
Service of process (constable or process server)Varies by county; ask the sheriff or constable's office, or the process server
DNA testing (court-ordered)Varies; ask the court or the testing provider
Mediation (if not court-provided)Varies; ask the court or the mediator
Certified birth certificate copy$22 (DSHS)

Fee waiver available

If you cannot afford court costs, file the Statement of Inability to Afford Payment of Court Costs (fee waiver) under Texas Rule of Civil Procedure 145. The test is whether you can afford the costs, and once a sworn Statement is filed the clerk must docket your case and issue citation. Proof that you or your dependent receive a means-tested government benefit, or that a qualifying legal aid provider is representing you or found you financially eligible, is prima facie evidence that you cannot pay. The rule mentions 200% of the federal poverty guidelines only to describe which legal aid nonprofits qualify; it does not set an income cutoff for the waiver. A “sworn” Statement can be signed before a notary or made under penalty of perjury (TRCP 145(b)). The form is available in English and Spanish.

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

Common questions

How do I establish paternity as an unmarried father in Texas?

If you were never married to the mother, you must first establish paternity before you can get conservatorship or possession rights. You can sign an Acknowledgment of Paternity (AOP) voluntarily with the mother through DSHS, or if she refuses, file a Petition to Adjudicate Parentage (FM-Pat1-100) in district court. The court can order DNA testing. Once paternity is established, you can file a SAPCR petition for conservatorship and possession and access.

How do I get custody if I was never married to the other parent?

In Texas, a parent becomes a managing conservator only when a court appoints one (Section 153.005), and in deciding conservatorship and possession the court must consider the parents' qualifications without regard to sex or marital status (Section 153.003). What changes for unmarried parents is who is a legal parent: the mother-child relationship is established by giving birth, while for an unmarried father the father-child relationship is usually established by an unrebutted presumption of paternity, an effective acknowledgment of paternity, or a court adjudication (Section 160.201). File a Petition in SAPCR (FM-SAPCR-100) to request joint managing conservatorship and a possession and access schedule. You can include a paternity allegation in the same petition. Texas law presumes that naming both parents joint managing conservators is in the child's best interest (Section 153.131). The Expanded Standard Possession Order (ESPO) is the default when the noncustodial parent lives 50 miles or less from the child's primary residence (Section 153.3171), unless one of that section's exceptions applies, such as the parent declining it or the court finding it is not in the child's best interest.
