Texas Stepparent Adoption: Process, Cost, and Legal Requirements

Stepparent adoption in Texas formalizes a relationship that already exists in everyday life. When the process goes smoothly, it can be one of the simpler adoptions in the state. When the other biological parent resists, it becomes a contested termination case. Understanding which category you are in before you file determines almost everything about cost and timeline.

The Legal Framework

Stepparent adoption is authorized under Texas Family Code § 162.001(b)(2). A stepparent can adopt their spouse's biological child without terminating the spouse's parental rights — that relationship stays intact. What must be terminated is the parental relationship of the other biological parent. This makes stepparent adoption legally a combined suit: a Termination of Parental Rights (TPR) followed immediately by an adoption.

The case is filed in the District Court or a statutory county court with family law jurisdiction in the county where the child lives or where the petitioner lives.

When the Other Parent Consents

The cleanest path is a voluntary relinquishment — the other biological parent agrees to terminate their parental rights. They sign an Affidavit of Voluntary Relinquishment, witnessed by two credible persons and notarized. Once signed with an irrevocability clause, it is final.

In a straightforward consent case, the process typically takes 4 to 8 months:

1. File the combined petition for TPR and adoption
2. Complete the adoption evaluation (home study), unless waived — courts have discretion to waive certain home study requirements for stepparent cases where the child has lived in the home for an extended period
3. Conduct background clearances (FACT/DFPS system and FBI fingerprinting for all adults in the household)
4. Await the 6-month post-petition residency period, then request a finalization hearing
5. Attend the hearing; if the child is 12 or older, they must provide written consent

Note: the 6-month minimum residency period in Texas applies to all adoptions, including stepparent cases. The child must reside in the home for at least 6 months before finalization.

When the Other Parent Does Not Consent

If the biological parent will not voluntarily relinquish, you must prove involuntary grounds for termination under TFC § 161.001 by "clear and convincing evidence." The most commonly used grounds in stepparent cases include:

• Abandonment: The parent voluntarily left the child with no intent to return and no plan for support
• Failure to support: The parent failed to pay child support for a period of one year in accordance with their financial ability
• Criminal conduct: The parent was convicted of a crime resulting in incarceration for at least two years
• Endangerment: The parent knowingly placed or allowed the child to be in conditions that endangered physical or emotional well-being

Courts also apply the "best interest of the child" standard independently — meaning even if you establish one of the grounds above, the judge still evaluates whether termination is affirmatively in the child's interest.

Contested cases take significantly longer — often 12 to 24 months — and attorney fees escalate accordingly. Depositions, discovery, and a full trial are possible in contested terminations.

What a Stepparent Adoption Costs in Texas

An uncontested stepparent adoption typically runs $1,500 to $3,500 in total — attorney fees for drafting the petition and relinquishment affidavit, court filing costs, and any home study or background check fees. If the court appoints an attorney ad litem for the child (required in many Texas counties even in stepparent cases), that adds $500 to $1,000 depending on the county.

A contested case can reach $10,000 to $25,000 or more once litigation is involved. Legal fees are largely driven by how hard the other parent fights the termination, whether depositions are required, and whether expert witnesses are called on the "best interest" question.

After the Decree: Name Change and New Birth Certificate

The Decree of Adoption changes the child's legal last name (if requested in the petition) and establishes the stepparent as a full legal parent. The adopting attorney then files with the Texas Department of State Health Services to obtain a new birth certificate that lists both the custodial parent and the stepparent as the child's legal parents.

The original birth certificate is sealed. For adult adoptees who later want access to the original record, Texas Health and Safety Code § 192.008 provides a path to obtaining a non-certified copy if the adult adoptee already knows the names on the original certificate.

One Practical Note on Timing

Many families underestimate the Texas Paternity Registry obligation even in stepparent cases. If the child is younger and the non-custodial parent's identity is disputed, your attorney must still conduct a registry search and file the Certificate of Search with the court. It is a mandatory checklist item regardless of pathway.
