Types of Adoption: The 7 Kinds, and How Open Each Can Be

People use “types of adoption” to mean two different things: the legal path (agency, private, foster care, international, stepparent, relative, adult) and the level of contact afterward (open, semi-open, closed). This guide covers both, in plain language, and ends with how to tell which one fits your situation.

Written from thirty years of agency practice. Foster care and international adoption are described for completeness; our agency provides domestic infant adoption only.

Last updated: October 10, 2026

The short version: there are seven legal types of adoption. Domestic infant adoption through a licensed agency and private adoption through an attorney both place newborns. Foster care adoption places children in state custody, international adoption brings a child from another country, and stepparent, relative, and adult adoptions make an existing relationship legal. Within most of these, the families decide how much contact to keep: open, semi-open, or closed.

Key Takeaways

  • How many types of adoption are there? Seven legal types: domestic infant, private, foster care, international, stepparent, relative, and adult adoption. Inside most of them, the contact between families is described as open, semi-open, or closed.

  • What is the most common type of adoption? Foster care adoption by number of children, and domestic infant adoption by number of families actively seeking to adopt a baby. Open and semi-open arrangements are now the norm in infant adoption.

  • What is a closed adoption? An adoption where no identifying information is exchanged and there is no contact after placement. Records are sealed, though many states offer registries that can connect the parties later if both agree.

  • What is the difference between agency and private adoption? An agency provides counseling, matching, legal coordination, and post-placement support under a state license. A private adoption relies on an attorney for the legal steps, and the families arrange everything else themselves.

  • Which type does A Act of Love Adoptions provide? Domestic infant adoption, open or semi-open in most cases, for birth mothers nationwide and adoptive families who complete a home study.

The 7 Legal Types of Adoption

The legal type answers three questions: who arranges the placement, how old the child usually is, and what the court requires before it signs the decree. Here is each one.

Not every adoption begins with a newborn. Stepparent, relative, and adult adoptions make a family that already exists legal.

1. Domestic Infant Adoption (Agency Adoption)

A pregnant woman, or a mother with a newborn, chooses to place her baby with a family she selects, and a licensed agency handles everything around that choice: options counseling, matching with waiting families, the hospital plan, legal consent, and support for both families after placement. It is the most common way a baby is adopted in the United States and the only type of adoption A Act of Love Adoptions provides.

2. Private (Independent) Adoption

In a private adoption the birth mother and adoptive family find each other on their own, often through friends, family, or a mutual contact, and an attorney handles the legal work: consent, notice to the birth father, the home study referral, and finalization. There is no agency matching, and counseling for the birth mother is not automatic unless the state requires it.

Private adoption is legal in most states, including Utah, and many families combine it with agency services for the pieces an attorney does not cover. Our private adoption page compares the two paths in detail.

3. Foster Care Adoption

Foster care adoption usually begins with fostering. Most children are school age, and many have siblings who need to stay together.

Children in foster care become eligible for adoption when a court has terminated their parents' rights and no relative can take them. Families adopt through the state agency (in Utah, the Division of Child and Family Services) or a contracted foster agency, usually after fostering the child first. Costs are low or covered, and many children qualify for ongoing adoption assistance. A Act of Love does not place children from foster care; families interested in this path can start with the state program or AdoptUSKids.

4. International Adoption

International adoption places a child from another country with a family in the United States. It runs under the Hague Adoption Convention and U.S. immigration law, so the agency must be Hague accredited and the family needs both a home study and approval from U.S. Citizenship and Immigration Services. Each sending country sets its own eligibility rules for parents' age, marriage, health, and income, and the number of international adoptions has fallen sharply over the past two decades as countries have changed their programs.

5. Stepparent Adoption

A stepparent adoption makes a spouse the legal parent of their partner's child. The child's other legal parent must consent, or have their rights terminated by the court for abandonment or failure to support. Because the child already lives in the home, many states shorten or waive the home study. Utah's courts publish self-help forms for stepparent adoptions, and most families use a family law attorney for the filing.

6. Relative (Kinship) Adoption

Kinship adoption often starts long before the paperwork, when a relative steps in to raise a child.

A grandparent, aunt, uncle, or adult sibling adopts a child who is already family. Kinship adoptions often begin as an informal or court-ordered placement when a parent cannot care for the child, and move to adoption when permanence is needed for school, medical, and legal decisions. Birth parents must consent or have their rights terminated, and the court still confirms the home is safe, though many states adapt the home study for relatives.

7. Adult Adoption

An adult can be adopted by another adult, most often a stepparent or former foster parent making a lifelong relationship legal, or to establish inheritance rights. Only the adoptee's consent is needed, and there is no home study. It is a short court process in most states. Age rules for every type, including adult adoption, are in how old you have to be to adopt.

A note on embryo adoption: families sometimes ask where it fits. Legally it is a donation governed by contract in most states rather than an adoption under the adoption statute, which is why it is not counted among the seven types here.

Types of Adoption FAQ

What are the different types of adoption?+

The seven legal types are domestic infant adoption through an agency, private or independent adoption through an attorney, foster care adoption, international adoption, stepparent adoption, relative or kinship adoption, and adult adoption. Each one can also be described by how much contact continues afterward: open, semi-open, or closed.

Which type of adoption is most common today?+

By number of children, adoption from foster care is the largest category in the United States. Among families seeking to adopt a baby, domestic infant adoption through a licensed agency is the most common path, and most of those adoptions are open or semi-open.

What is a closed adoption?+

A closed adoption is one in which no identifying information is exchanged between the birth family and the adoptive family and there is no contact after placement. The court file is sealed. Closed adoptions were standard for much of the twentieth century and are now the least common arrangement.

What is the difference between open and closed adoption?+

Contact. In an open adoption the families know each other and stay in touch through letters, photos, calls, or visits. In a closed adoption they do not exchange identifying information and have no contact. Semi-open adoption sits between the two, with updates passed through the agency.

What is the difference between agency and private adoption?+

An agency adoption is coordinated by a state-licensed agency that provides counseling, matching, legal coordination, medical and hospital planning, and post-placement support. A private or independent adoption is arranged directly between the birth mother and the family, with an attorney handling consent, notice, and finalization but no built-in counseling or matching.

Which type of adoption is fastest?+

Stepparent and adult adoptions are usually the quickest because the relationship already exists and the court process is short. Among adoptions of a child new to the family, foster-to-adopt and domestic infant adoption typically take one to two years; international adoption often takes longer.

Can I change the type of adoption after placement?+

The legal type does not change, but the level of openness can. Many semi-open adoptions grow into open ones as trust builds, and the agency can mediate. In some states, including Utah, a court-approved post-adoption contact agreement can be recognized, though breaking one never undoes an adoption.

Can a single person adopt?+

Yes, in every type of adoption. Single adults complete the same home study as couples. Utah law does not allow adoption by an unmarried adult who is cohabiting in a relationship that is not a legal marriage, and other states have their own rules.
