Yes! Hyphenating the child's last name is a popular option during stepparent adoption in Illinois. Many families choose this to honor both the biological family name and the adoptive family name.

How it works:

  • Specify the hyphenated name on the Petition for Adoption
  • The Circuit Court judge approves it as part of the adoption order
  • The new birth certificate from Illinois Department of Public Health Division of Vital Records reflects the hyphenated name

Examples:

  • Child's current name: "Jane Smith" → becomes "Jane Smith-Johnson"
  • Child's current name: "Michael Davis" → becomes "Michael Davis-Williams"

Why families choose hyphenation:

  • The child can keep a connection to their birth name
  • It honors both families
  • The child gets the stepparent's name as well
  • It can ease the emotional transition for older children

Other name options during adoption:

  • Change to the stepparent's last name entirely
  • Keep the current name unchanged
  • Change the middle name (some add the biological surname as a middle name)
  • Change first, middle, and last name

There is no extra cost — name changes are included in the adoption. Our $349 fee covers all document preparation regardless of name change choices.
