Step parent adoption without bio father consent only happens in reserved situations, as most states require the custodial and non-custodial parent’s consent to go ahead with a stepparent adoption.

Step parent adoption without bio father consent

While this is often one of the easiest adoption types, it can be problematic if the biological father is unknown, can’t be located, or doesn’t consent to the adoption. However, you can file a motion to terminate the bio father’s parental rights and allow the adoption to proceed. This article highlights some grounds for adopting without the birth father’s consent and the general adoption process.

What Is Stepparent Adoption Without Bio Father Consent?

Stepparent adoption without bio father consent is when one adopts the biological child of their spouse without the approval of the birth father. By adopting their spouse’s child, the stepparent can step up and assume the biological parent’s roles and responsibilities.

What Are the Grounds for Step Parent Adoption Without Bio Father’s Consent?

The grounds for step parent adoption without bio father’s consent are abandonment, parental unfitness and paternity issues. However, the prospective stepparent has to prove any of these grounds and show that they made a reasonable effort to locate the bio father before requesting adoption without their consent.

– Adoption Without Parent’s Consent Due to Abandonment

Adopting can be arduous when the other parent is unavailable, and you can’t get their consent. However, family law in most states allows for a stepparent adoption if you can show that the bio father hasn’t contacted the child or exercised their parental duties in a long time.

Laws regarding abandonment differ among states, but most require that at least one year passes without the parent communicating or supporting the child. However, termination of the parental relationship might be complicated if the other parent pays child support but doesn’t visit or exercise other parental duties.

– Adoption Without Parent’s Consent Due to Parental Unfitness

Courts can terminate the biological father’s parental rights if they have an alcohol or drug addiction, child abuse history, or criminal history. Usually, the court will hear the adoption petition and determine whether it is in the child’s best interest for that parent to continue exercising their parental relationship.

In such cases, courts will determine the prospective stepparent’s stability and ability to provide the child with a safe and stable life. After the determination, the court might terminate the other birth parent’s rights and give the step-parent adoption the green light.

Still, an adoption case where one birth parent doesn’t consent can be challenging. It is important for the parties involved to consult an adoption attorney to help with their case in court.

– Adoption Without Parent’s Consent Due to Paternity Issues

A court might terminate the parental relationship of an absent presumed father with the child if you can prove that he isn’t the child’s biological parent. Paternity laws may vary among states, and it is important to understand what your state’s laws provide before filing a petition.

In many states, when a child is born of a heterosexual couple, the mother’s husband is presumed to be the child’s father. Therefore, the child’s birth certificate indicates that the husband is the child’s bio father.

However, this presumption may later be revealed wrong, and the parent can refute this presumption through a legal process and procedure provided by state law. You can proceed with the adoption by proving that the presumed father isn’t actually the biological father.

Yet, the other parent may still object and prove the accuracy of the presumed parenthood. In such cases, it is unlikely for the court to allow the adoption process to proceed. That means you have to work with the parent to obtain their consent.

Alternatively, you could find another reason for having their parental relationship terminated, such as parental unfitness, abandonment, or any other reason permissible by state law.

What is the Process of Adoption Without the Bio Father’s Consent?

The process of adoption without the bio father’s consent is similar to any other adoption type. It follows particular steps provided by state law, but the general process involves requesting adoption, investigation by a state’s social services agency, and proving that you couldn’t obtain the bio father’s consent.

– Adoption Request by the Prospective Stepparent

When it comes to step parent adoption without bio father consent, Kansas residents must request a Superior Court in their residence county by filing an Adoption Request, as is in other states. The request must contain your essential details and those of the child you want to adopt.

The court also requires you to provide information regarding your relationship with your prospective stepchild and other parents or guardians of the child. After filing the Adoption Request, the court begins the formal proceedings.

– Investigation by the State’s Social Services Agency

The State’s social services agency conducts an investigation or a home study and files a report with the court. The investigation is meant to verify relevant details and whether it’s in the child’s best interests before letting the husband adopt.

In addition to parental consent, you must obtain the child’s consent before adopting, but the child must be 10-14 years old. For instance, when it comes to step parent adoption without bio father consent, California still requires children aged 12 and over to consent.

– Obtaining the Bio Father’s Consent

You need to obtain the bio father’s consent before the court finalizes the step parent adoption. If you can’t obtain the father’s consent, you may request the court to terminate their parental relationship by proving abandonment, parental unfitness, or inaccurate parenthood presumption.

In the case of an absent birth father, the prospective stepparent has to put in a reasonable effort to locate him before requesting the court to terminate his parental relationship.

Such steps could include searching motor vehicle registration records, obtaining county records of where he may currently reside, or posting a notice to his last known address. In most cases, the court will require evidence indicating efforts to locate the absent bio father.

If you take reasonable steps to locate him and still fall short, you can seek termination of the parental relationship with your prospective stepchild.

Are Stepparent Adoptions in Joint Custody Cases Feasible?

Stepparent adoptions in joint custody cases are feasible and can be successful if the custodial parent has sole custody. However, non-custodial parents with joint custodial rights will almost certainly not give away their parental rights for you to adopt, in most cases.

So for the question “can my husband adopt my child if I have sole custody?” beware that the adoption process becomes even more complicated if the bio father has joint custody with the custodial parent.

However, you can ask a court to grant legal guardianship, especially if the non-custodial parent is absent. That way, you can have some legal rights regarding the child’s care.


Stepparent adoption without bio father consent is only possible in specific circumstances, as discussed throughout the article. Here are the main points of the discussion:

  • Adopting a prospective stepchild without the biological father’s consent can be difficult but not impossible.
  • To proceed with the adoption without the father’s consent, you must prove parental unfitness, abandonment, or inaccurate parenthood presumption.
  • Before requesting the termination of the parental rights of an absent father in court, you must show that you put in reasonable efforts to locate the bio father.
  • Step-parent adoptions can be complicated, and it is advisable that you work with an experienced family law attorney to guide you through the process.

Adoption without a parent’s consent may be a complex process. If the non-custodial parent has joint custody, you may explore other options, including pursuing legal guardianship with the help of your attorney.
