Understanding the Various Forms of Adoption

 Posted on May 12, 2026 in Kane

If you’re considering adoption, the first step is understanding what types of adoption there are. Whether you're hoping to adopt a newborn, a child in foster care, a stepchild, or a relative, there are specific legal processes each type goes through. A St. Charles adoption lawyer can advise you through any kind of adoption you’re hoping to pursue in 2026.

How Does Domestic Infant Adoption Work in Illinois?

Domestic infant adoption is what most people picture when they think about adoption. This involves a birth mother (and often a birth father) voluntarily placing a newborn with an adoptive family. This process is governed by the Illinois Adoption Act (750 ILCS 50), which outlines the requirements for consent, placement, and finalization.

In Illinois, birth parents can't legally consent to an adoption until after the child is born. Once consent is given, it becomes very difficult to undo. Adoptive families typically work with a licensed adoption agency or an adoption attorney to be matched with a birth parent.

What Role Does an Agency Play in an Illinois Adoption?

Licensed adoption agencies screen prospective adoptive parents by performing things like background checks and home studies. They also match families with infants to adopt and provide counseling to birth parents.

Some families pursue independent or private adoptions. For these, an attorney handles the legal process directly without an agency. Both paths are an option in Illinois. Each has trade-offs in terms of cost, timeline, and level of support.

How Does Illinois Handle Foster Care Adoption?

Foster care adoption involves adopting a child who is in the Illinois Department of Children and Family Services (DCFS) system. Many children in foster care have experienced abuse, neglect, or abandonment. Parental rights may already be in the process of termination or have been terminated by the court in these cases. This type of adoption is often less expensive than private adoption. For special needs children, families may get financial support from the state to cover their additional needs.

Foster care adoption is a meaningful way to provide a permanent home for an older child or sibling group who may be harder to place. However, it can be complex legally and emotionally. This is especially true if reunification with birth parents is a possibility during the process.

Once parental rights are ended, and a child is legally able to be adopted, the adoptive family goes through the court process to finalize the adoption. If a family was previously fostering a child, Illinois allows that family to pursue adoption when reunification with the birth parents is removed from the picture.

What if I Want To Adopt My Stepchild or Relative in Illinois?

Stepparent and relative adoptions are among the most common adoptions in Illinois. In some cases, they may be fairly straightforward. Still, they come with their own legal requirements.

Stepparent Adoption

In a stepparent adoption, a spouse or partner legally adopts their partner's child. For this to happen, the other birth parent must either consent to the adoption or have their parental rights terminated by the court. If that parent is actively involved in the child's life, getting their consent for adoption or meeting the legal threshold for termination may be difficult.

If consent is given and the adoption is finalized, the adoptive stepparent takes on full legal parental responsibilities for the child. The birth parent who gave up rights no longer has any legal connection to the child.

Relative (Kinship) Adoption

Kinship adoption happens when a grandparent, aunt, uncle, sibling, or other relative steps in to permanently adopt a child. These cases often arise after difficult situations such as a parent's death, incarceration, or chronic illness. It’s also common in cases of abuse or neglect. Courts are supportive of keeping children within families if possible and often approve kinship adoptions. Recently, new legislation called the KIND Act was signed, making these adoptions more accessible.

Even in kinship adoptions, a home study is usually required, and the birth parents' rights must be addressed. The process still goes through the court system, and legal representation is strongly recommended.

Can Adults Be Adopted in Illinois?

Adult adoption is less commonly discussed, but it is permitted under Illinois law. Adults may be adopted in situations where a long-standing parent-child relationship already exists. This may be a stepparent who raised a child but never formally adopted them, or a family member who took on a parenting role years ago.

Adult adoption requires the consent of both the person being adopted and the adoptive parent. It can carry meaningful legal and personal significance, including inheritance rights and the ability to legally formalize a relationship that has existed in practice for years.
