Can a same-sex stepparent adopt in Illinois?

Yes, a same-sex stepparent can adopt their spouse's child in Illinois. You file a stepparent adoption in the Circuit Court in your county, using the same Illinois process as any other stepparent family under Illinois Compiled Statutes 750 ILCS 50.

What the Illinois process looks like

• Residency: There is no residency period for a stepparent adoption. The 6-month rule does not apply to a related child (750 ILCS 50/2).
• Child's consent: The consent age is 14 (750 ILCS 50/12). If your child is 14 or older, their consent is part of the process.
• The other legal parent: Illinois law addresses a parent who has abandoned a child, using a 12-month period (750 ILCS 50/1). Illinois also has procedures for cases where the other parent cannot be located, and these are handled within the adoption proceeding. If the other parent's role is unclear or disputed, speak with an attorney or the Circuit Court clerk about your specific facts.
• Home study: Illinois does not require a home study for most stepparent adoptions (750 ILCS 50/6).
• Timeline: A stepparent adoption typically takes about 3-6 months.

Cost

Court filing fees generally run $200-$500 across Illinois's 102 counties, and the typical total cost is under $565. Hiring an attorney for a stepparent adoption often runs $3,000-$5,000+.

What the law protects for your family

Adoption establishes inheritance rights, gives the adopting stepparent medical decision-making authority, opens eligibility for Social Security and insurance benefits, and recognizes your family in law.

Situations that need individual confirmation

Some situations depend on your particular facts. These include couples who are not married, a child with a second legal parent, a contested case, and an other parent who cannot be found. Illinois law on those points should be confirmed with the Circuit Court clerk in your county or an attorney. Questions about the child's birth record after the adoption can go to the Illinois Department of Public Health Division of Vital Records, and your clerk can explain the steps.
