Step 1: Determine Who May File

Not everyone has standing to file a SAPCR. Under Texas Family Code § 102.003, the following persons may file an original SAPCR:

• A parent of the child
• The child, through a representative authorized by the court
• A custodian or person having court-ordered access to the child
• A guardian of the person or estate of the child
• A governmental entity, including the Texas Department of Family and Protective Services
• An authorized agency
• A foster parent who has had actual care, control, and possession of the child for at least 12 months ending not more than 90 days before the filing
• A person related to the child within the third degree of consanguinity (such as a grandparent), if the child's present circumstances would significantly impair the child's physical health or emotional development

If you do not fall into one of these categories, the court may dismiss your case for lack of standing. Under TRCP Rule 7, any party to a SAPCR may appear and be represented by an attorney. If you have an attorney, they will enter an appearance on your behalf under TRCP Rule 120.

Step 2: Prepare the Original Petition

The Original Petition in Suit Affecting the Parent-Child Relationship is the document that initiates the case. It must include:

• The full legal names, dates of birth, and current addresses of both parents and all children
• The county where the child has resided for the past six months (this establishes venue)
• The relief you are requesting (conservatorship, possession, child support, etc.)
• A statement of whether a protective order, restraining order, or other court order affecting the parties or children is in effect

Free, court-approved petition forms are available from TexasLawHelp.org. Your county law library may also provide forms and self-help resources.

Citation

Along with the petition, you must request a Citation from the district clerk. The citation is the official court document that notifies the respondent that a lawsuit has been filed and that they must file an answer by a specific deadline. The citation is issued by the clerk and must be served along with a copy of the petition.

Step 3: File with the District Clerk

The petition must be filed with the district clerk in the county where the child has resided for the preceding six months. If the child has not resided in any single county for six months, the petition should be filed in the county where the child currently resides.

Electronic Filing Through eFileTexas.gov

Texas courts require electronic filing in most counties. You can file your SAPCR petition through eFileTexas.gov, the state's official e-filing system. There is no additional charge for using eFileTexas beyond the standard filing fee. The system is available 24 hours a day and generates a filing confirmation with a timestamp.

Filing Fees

Filing fees vary by county. In Harris County, the filing fee for an original SAPCR is approximately $450. Other counties may charge more or less. If you cannot afford the filing fee, you may file a Statement of Inability to Afford Payment of Court Costs under TRCP Rule 145. If granted, this waiver covers the filing fee, service fees, and other court costs. You do not need the court's permission in advance; you file the statement, and the clerk must accept your filing. The opposing party or the court may challenge the statement, but your case proceeds while any challenge is pending.

Step 4: Serve the Other Party

After filing, the respondent must be served with a copy of the petition and the citation. Service of process is governed by the Texas Rules of Civil Procedure and is one of the most critical steps in the process. Improper service can result in a void judgment or, conversely, can be used to obtain a default judgment against a respondent who never received notice.

Methods of Service

Under TRCP Rule 99, the clerk issues citation directing the respondent to file an answer. TRCP Rule 103 specifies who may serve process:

• A sheriff or constable
• A person authorized by court order (such as a private process server)
• A certified process server

Constable service typically costs $75 to $150 depending on the county. Private process servers may charge more but can sometimes complete service faster.

Alternative Service

If the respondent cannot be personally served after reasonable efforts, TRCP Rule 106 allows the court to authorize substitute service, such as service by leaving the citation at the respondent's usual place of abode with anyone over 16 years of age, or service by posting or publication in certain circumstances.

Return of Service

Under TRCP Rule 107, the person who serves the citation must file a return of service with the court. The return must state when, where, and how service was made, and must be signed and sworn to by the person who performed the service. The return of service is the court's evidence that the respondent was properly notified. A defective or missing return of service can be grounds for setting aside a default judgment.

Step 5: The Answer Deadline

Once the respondent is served, they must file an answer by 10:00 AM on the first Monday after 20 days from the date of service, as specified in TRCP Rule 99. For example, if the respondent is served on a Wednesday, the 20-day clock begins that day, and the answer is due at 10:00 AM on the first Monday after the 20th day.

If the respondent fails to file an answer by this deadline, the petitioner may request a default judgment. This means the court can grant the petitioner everything requested in the petition without hearing the respondent's side.

Common SAPCR Filing Mistakes to Avoid in Texas

• Filing in the wrong county: The petition must be filed in the county where the child has resided for the past six months. Filing in the wrong county can result in dismissal or transfer.
• Incomplete petition: Missing information about parties, children, or requested relief can delay your case.
• Failing to serve the respondent properly: Defective service can void a judgment and waste months of time. Always use an authorized server and ensure the return of service is filed.
• Missing deadlines: If you are the respondent, failing to file your answer by the TRCP Rule 99 deadline exposes you to a default judgment.
• Not requesting a fee waiver when eligible: Many self-represented litigants pay fees they cannot afford. TRCP Rule 145 exists for this purpose.
• Failing to disclose existing orders: You must disclose any protective orders, prior custody orders, or pending cases involving the child.

After Filing a SAPCR in Texas: What Happens Next

Once the petition is filed and the respondent is served, the case moves into the discovery and pre-trial phase. The court will typically set a scheduling order, and both parties will have the opportunity to exchange information through discovery. Most SAPCR cases in Texas require mediation before a trial setting. For more details on the timeline and costs of a SAPCR, see our dedicated guides.

Frequently Asked Questions

Where do I file a SAPCR in Texas?

Generally in the county where the child has lived for the six months preceding filing, under Texas Family Code section 103.001. If another court already has continuing exclusive jurisdiction over the child from a prior case, that court is normally where the matter belongs.

What forms do I need to file a SAPCR?

At minimum an Original Petition in a Suit Affecting the Parent-Child Relationship, plus any county-required civil case information sheet and, if you cannot afford court costs, a Statement of Inability to Afford Payment of Court Costs under Rule 145. Free court-accepted forms are available from TexasLawHelp.org.

How do I serve the other parent?

You do not serve the papers yourself. Service is performed by a sheriff, constable, clerk, or an authorized process server under Rule 103. Personal service and certified mail are the standard methods under Rule 106, and substituted service or service by publication require a supporting affidavit and a court order first.

What happens after the other parent is served?

Their answer is due at 10:00 a.m. on the Monday following the expiration of twenty days from service, under Rule 99. If an answer is filed, the case becomes contested and proceeds toward temporary orders, discovery and mediation. If none is filed, the petitioner may seek a default judgment.

Can I file a SAPCR without a lawyer?

Yes. Texas permits self-representation under Rule 7, e-filing is free through eFileTexas, and Rule 145 can waive court costs if you cannot afford them. Accuracy matters most in the service step, because defects there can invalidate any resulting order.
