Can Same-Sex Couples Adopt a Child in Illinois?

 Posted on October 07, 2026 in LGBTQ+ Family Law

Same-sex couples can adopt in Illinois with the same rights and the same process as any other couple. Illinois law does not distinguish based on sexual orientation or gender identity. The state has permitted joint adoption by same-sex couples for years.

Families should also take steps to protect their legal rights as parents. This is especially important when children are conceived with medical help or families travel to states with different laws. If you are building your family in 2026, a Wrigleyville, IL LGBTQ+ family law lawyer can help you take the steps protect your legal rights as a parent.

What Does Illinois Law Say About Who Can Adopt?

The Illinois Adoption Act, 750 ILCS 50/2, explains who may adopt a child. The law focuses on whether the person is legally eligible to adopt and is a fit and proper adoptive parent. It does not exclude someone because of sexual orientation.

Illinois generally requires an adopting person to have lived in the state for at least six months before filing, although the law includes several exceptions to that residency requirement.

A same-sex married couple can file jointly just as any other married couple can. An unmarried individual can also adopt regardless of sexual orientation.

What Types of Adoption Are Available to Same-Sex Couples?

Illinois offers several paths to adoption, and the right one depends on your family's situation:

• Agency adoption, working through a licensed public or private agency

• Private or independent adoption, arranged directly with a birth parent

• Foster care adoption through the Department of Children and Family Services

• Related adoption, when the child is a relative of one of the parents

• Stepparent adoption, where one spouse adopts the other's child

• International adoption, subject to the requirements of the child's home country

Each carries different timelines, costs, and home study requirements. International adoption deserves extra scrutiny, since some countries restrict or refuse placements with same-sex couples regardless of what Illinois permits.

Why Do Married Same-Sex Parents Still Need an Adoption or Parentage Judgment?

When a married couple has a child, Illinois law may recognize both spouses as legal parents, depending on how parentage was established. A birth certificate can reflect that parentage. However, it’s not the same thing as a court judgment.

A court judgment of adoption or parentage provides stronger protection when a family travels or moves to another state. Under the Full Faith and Credit Clause, other U.S. states must recognize a valid Illinois judgment. Recognition in another country, however, depends on that country’s own laws.

How Does Assisted Reproduction Affect Parentage in Illinois?

Illinois law explains who is a legal parent when a child is conceived with medical help, such as IVF or donor sperm. These rules apply regardless of the parents’ gender. A person who consents to assisted reproduction with the intent to be a parent can be recognized as a legal parent. A donor, on the other hand, is not a parent simply because they provided sperm or eggs.

Consent can be shown through a signed record or a qualifying agreement. In some cases, a court can find that a person consented to parentage if they lived with the child and openly treated the child as their own during the first two years of the child’s life.

Illinois also allows gestational surrogacy. The process requires a written agreement, separate lawyers for the parties, and certain evaluations. If the legal requirements are met, the intended parents can be recognized without needing to adopt the child after birth.

What Does the Illinois Adoption Process Involve?

Most adoptions begin with a home study conducted by a licensed agency or social worker. They examine your home, finances, health, background checks, and references. Related and stepparent adoptions sometimes have reduced requirements.

You then file an adoption petition in the circuit court where you or the child lives. The birth parents must usually consent to the adoption unless the court has terminated their parental rights. In Illinois, a properly signed consent is usually final.

Children age 14 or over must consent to their own adoption. A temporary court order can place the child with you while the case proceeds. The judge finalizes the adoption after a hearing, which is usually brief and celebratory.
