Can I adopt my stepchild if I'm in a same-sex marriage in Illinois?

Yes, as a married stepparent in Illinois, you can pursue adopting your stepchild through the Circuit Court in your county. Your family goes through the Illinois stepparent adoption process, which is filed with the Circuit Court in any of Illinois's 102 counties, including Cook County (Chicago), Kane (Aurora), DuPage and Will (Naperville and Joliet), and Winnebago (Rockford).

What Illinois asks of a stepparent adoption:

• 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: A child who is 14 or older must consent (750 ILCS 50/12).
• Other parent: Illinois sets an abandonment period of 12 months (750 ILCS 50/1) and has procedures for cases where the other parent cannot be located. These are handled within the adoption proceeding.
• Home study: Illinois does not require a home study for most stepparent adoptions (750 ILCS 50/6).

Timeline and cost: A stepparent adoption in Illinois typically takes 3-6 months. Court filing fees generally run $200-$500, and the typical total cost with our service is under $565. Hiring an attorney for the same adoption often costs $3,000-$5,000+.

Why families do it: Adoption establishes inheritance rights, gives the adopting stepparent medical decision-making authority, and opens eligibility for Social Security and insurance benefits. It also gives your family's bond legal recognition.

When your situation needs a closer look: If the other parent is involved, cannot be found, or may contest the adoption, the details depend on your specific facts. Ask the Circuit Court clerk in your county or an attorney about that issue. The clerk can also confirm local filing steps and anything particular to your county. For questions about the child's birth record after an adoption, the Illinois Department of Public Health Division of Vital Records is the state agency, and the clerk can point you to the right steps.
