Connecticut Stepparent Adoption Guide 2026

The short answer: in Connecticut, a stepparent adoption is handled by the Probate Court in the district where you live. Your spouse and you sign a written adoption agreement, and if the other parent won't or can't consent, your spouse asks the same court to terminate his rights, for example because he has failed to maintain a reasonable degree of interest, concern or responsibility for the child (Conn. Gen. Stat. § 45a-717). In our experience, about 80% of the stepparent adoptions we've completed went forward without the other biological parent's consent: the father never signed, and the judge approved the adoption anyway.

What Are the Legal Requirements for Stepparent Adoption in Connecticut?

Connecticut's adoption and termination laws are in chapter 803 of the General Statutes. The basics for a stepparent:

• A written agreement. A parent may agree in writing with his or her spouse that the spouse will adopt the child, subject to the Probate Court's approval (Conn. Gen. Stat. § 45a-724(a)(2)).
• The other parent's rights. The agreement works when the other parent has died, or when the parental rights of anyone else have been terminated. That termination can happen by consent or, far more often in our experience, without it.
• Where to file. The application and agreement are filed in the Probate Court for the district where the adoptive parent lives (§ 45a-727(a)(4)).
• The child's consent. If the child is 12 or older, the adoption can't be granted without the child's consent (§ 45a-724(b)).
• Best interests. The court enters the final decree when it is satisfied the adoption is in the child's best interests (§ 45a-733(b)).

Does the Other Parent Have to Consent?

No, not if the court terminates his rights. Here's what courts actually see: in most stepparent adoptions, the other parent never signs anything, and the judge grants the adoption.

In Connecticut, either parent may petition the Probate Court to terminate the parental rights of the other parent (§ 45a-715(a)). For a stepparent adoption, that's usually your spouse. The court can grant the petition when it finds, by clear and convincing evidence, that termination is in the child's best interest and that one of the statutory grounds applies (§ 45a-717(g)). The grounds that come up most in stepparent families:

Connecticut's statute doesn't set a fixed number of months for either ground. The court looks at the parent's conduct as a whole. A parent who hasn't called, visited or supported the child in years, with only a token gesture now and then, is the kind of conduct the statute describes.

If the other parent agrees

He can consent to the termination of his rights. Each consenting parent acknowledges the consent on the official court form, showing it's voluntary and informed (§ 45a-715(d)). When everyone consents, the adoption application is combined with the consent termination petition (§ 45a-724(b)), and a consent termination hearing is set within 20 days of filing (§ 45a-716(a)).

If the other parent has died

The surviving parent can agree with his or her spouse to the adoption directly (§ 45a-724(a)(2)(A)). You'll include a certified copy of the death certificate.

What If I Can't Find the Other Parent?

That doesn't stop the adoption. If his whereabouts are unknown, the petitioner searches diligently and files an affidavit describing the efforts made to find him (§ 45a-715(c)). Then, when he can't be served personally in Connecticut, the court orders notice by registered or certified mail, or by publication at least 10 days before the hearing. Publication runs in a newspaper of general circulation where he last lived, or, if no address is known, where the petition was filed (§ 45a-716(c)).

If he doesn't come forward, the case goes forward. Keep a dated log of every search you make (last known addresses, relatives, social media, public records); it makes the affidavit easy to write.

Can Unmarried Partners Adopt in Connecticut?

Yes, Connecticut's statute provides for it. A parent may agree in writing with "one other person who shares parental responsibility for the child" that the other person will adopt or join in the adoption, as long as the parental rights of anyone else have been terminated (§ 45a-724(a)(3)). The child's parent keeps his or her own rights. These adoptions follow the same simplified Probate Court procedure as stepparent adoptions (§ 45a-733). The Connecticut state guide covers the details.

Here is how a Connecticut stepparent adoption moves from filing to decree.

Step 1: Gather Your Documents

Step 2: File in Your Probate District

File the adoption application and written agreement in the Probate Court for the district where you live. If the other parent hasn't consented, your spouse files the petition to terminate his rights; it can be filed where the petitioner or the child lives (§ 45a-715(e)). The application includes a declaration that no other custody case is pending, or describes any that is (§ 45a-727(a)(2)). If your stepchild is 12 or older, the child joins in the termination petition (§ 45a-715(a)). Ask the court for its current filing fee.

Step 3: Notice to the Other Parent

For a termination petition, the court sets a hearing, generally within 30 days of filing, and notice goes to the parents, the child if 12 or older, the Commissioner of Children and Families and the Attorney General (§ 45a-716). A parent in Connecticut is served at least 10 days before the hearing; a parent who is out of state or can't be found receives notice by mail or publication, as described above.

Notice is a routine step, not an obstacle. Most parents who have already stepped away never respond.

Step 4: The Investigation Is Usually Waived

In most Connecticut adoptions, the Probate Court asks the Department of Children and Families or an agency for an investigation and report. Stepparent adoptions are different: the court shall waive the investigation and report unless good cause is shown for one, and it may waive notice to the Commissioner on the adoption application (§ 45a-733(a)). For the termination petition, the court may request an investigation and report, and must in a contested case (§ 45a-717(e)).

Step 5: The Hearing and Decree

At the hearing, the judge confirms the other parent's rights have been terminated (or that he has died), that a child 12 or older consents, and that the adoption is in the child's best interests. Then the court enters the final decree approving the adoption (§ 45a-733(b)). In most stepparent adoptions the hearing is short, and many families describe it as one of the happiest days of their lives.

If the other parent appears and contests the termination, the case can be transferred to the Superior Court (§ 45a-715(g)). That's the time to talk with a Connecticut family law attorney.

Step 6: New Birth Certificate and Records

After the decree, the vital records office in the state where your child was born issues a new birth certificate showing you as a parent. Order several certified copies of the decree for Social Security, school, medical and insurance records, and passports.

Once the decree is signed, you are your child's legal parent, with the same rights and responsibilities as any parent. The other biological parent's rights and responsibilities end, including the duty to pay child support going forward (Child Welfare Information Gateway). Whether back support already owed can still be collected depends on state law.

How Long Does It Take, and What Does It Cost?

Many uncontested adoptions finish within a few months. In Connecticut, the hearing timing on a termination petition (generally within 30 days of filing, or 20 days on consent), the 10-day notice period, any publication, and your Probate Court's calendar set most of the pace.

Stage	What sets the pace
Document preparation	How quickly you gather names, dates and records
Filing	Your Probate Court's processing time
Termination hearing	Set by statute shortly after filing; consent cases move fastest
Notice	At least 10 days before the hearing, by service, mail or publication
Adoption decree	Your court's calendar; the hearing itself is usually short

Our Connecticut document package is $349 for the first child, plus $99 for each additional child. Probate Court fees, service or publication, and certified copies are separate. See our stepparent adoption cost guide.

Frequently Asked Questions

Can I adopt my stepchild in Connecticut if the other parent hasn't been around for years?

Yes. Your spouse can ask the Probate Court to terminate his rights because he has failed to maintain a reasonable degree of interest, concern or responsibility for the child, or because there is no ongoing parent-child relationship (§ 45a-717(g)). In our experience, that's how most stepparent adoptions happen: the father never signs, and the judge approves the adoption anyway.

Does Connecticut require a specific period of no contact?

No fixed number of months is written into § 45a-717. The court looks at the parent's conduct as a whole, and a long record of no contact and no support, with only token gestures, is exactly what the statute describes.

What if I don't know where the other parent is?

Search diligently and file an affidavit describing your efforts. The court then orders notice by registered or certified mail or by newspaper publication at least 10 days before the hearing (§§ 45a-715(c), 45a-716(c)).

Does my stepchild have to consent?

Yes, if the child is 12 or older (§ 45a-724(b)). A child that age also receives notice of the hearing and joins in a termination petition.

Is a home study required for stepparent adoption in Connecticut?

Usually not. For a stepparent, the Probate Court must waive the investigation and report unless good cause is shown (§ 45a-733(a)).

Can my partner adopt my child if we're not married?

Yes. Connecticut allows a parent to agree with "one other person who shares parental responsibility for the child" to adopt, and the parent keeps his or her own rights (§ 45a-724(a)(3)).
