Adult Adoption in Colorado: Process, Inheritance Implications, and Caregiver Rights

Adoption is not just for young children. In Colorado, many families choose to legally solidify bonds that have existed for years through adult adoption. Whether you want to formalize a relationship with a stepchild who has reached adulthood, or you are a caregiver seeking legal rights for an adult with developmental disabilities, this process offers profound emotional and legal benefits. Because the adoptee is a legal adult, the state removes many of the complex hurdles associated with adopting minors. However, adult adoption permanently alters inheritance rights and family structures under Colorado law. Whether you live in Denver, Boulder, or Grand Junction, this guide will walk you through the essential steps.

Step-by-Step Adult Adoption Process in Colorado

Adult adoptions are generally straightforward because the state prioritizes the mutual consent of the two adults involved. The process is handled in the local District Court.

Step 1: Draft the Petition and Consents

The process begins by completing Form JDF 528, Colorado, Judicial Branch, Petition for Adult Adoption. Unlike a minor adoption, you do not need permission from the biological parents. The only people who must legally consent are the adopting parent(s) and the adult being adopted. If either party is married, their spouse may also need to provide formal consent.

Step 2: File at the District Court

You will file the completed petition at the District Court in the county where either the adoptive parent or the adoptee resides, such as the Denver Juvenile Court, Denver or the Larimer County District Court, Fort Collins. You will pay the initial filing fee at the clerk's office.

Step 3: Schedule the Hearing

Because there are no mandatory home studies, background checks, or waiting periods required for adult adoptions under C.R.S. § 14-1-101, the court will simply schedule a final hearing date. This is usually a very celebratory and brief event.

Step 4: The Final Decree

At the hearing, the judge will review the paperwork to ensure everything is voluntary. Once the judge signs the final decree (Form JDF 531, Colorado, Judicial Branch, Decree for Adult Adoption), the adult adoption is official. The final decree serves as full legal proof of the adoption and name change; the state does not reissue or alter the adult adoptee's original birth certificate.

Common Reasons for Adult Adoption

Families pursue adult adoption in Colorado for a variety of deeply personal and practical legal reasons.

Adopting a Stepchild Who Aged Out of the System

Often, a stepparent or foster parent raises a child but cannot legally adopt them before their 18th birthday due to an uncooperative biological parent refusing to relinquish rights. Once the child turns 18, the biological parent loses all veto power. The adult child and the stepparent can immediately file for adoption to legally recognize the true parental bond.

Caregivers Adopting an Adult with Developmental Disabilities

While adult adoption formalizes emotional bonds and establishes the adoptee as a legal heir at law, it does not automatically grant the caregiver authority to make medical or financial decisions for an adult with special needs. To obtain the legal authority to handle healthcare, housing, and financial affairs for an incapacitated adult, caregivers must establish a legal guardianship or conservatorship under the Colorado Uniform Guardianship and Protective Proceedings Act (C.R.S. § 15-14-101 et seq.) or execute a durable power of attorney.

Establishing Heir at Law Inheritance Rights

Under C.R.S. § 14-1-101, an adult adoption legally designates the adopted adult as an "heir at law," entitling them to inherit from the adoptive parent through intestate succession just like a biological child. Crucially, unlike minor adoptions, adult adoption does not terminate the parental rights of the biological parents, nor does it legally sever existing familial ties. Unless a biological parent's estate planning documents specifically exclude the adopted individual, the adoptee does not automatically lose their right to inherit from biological family members.

The Simplified Adult Name Change Procedure

Many adult adoptees use this process to formally change their last name to match their new family. Instead of going through the separate, standard Colorado adult name change process (which requires publishing notices in a newspaper and separate background checks), the name change can be smoothly integrated directly into the adult adoption decree, saving both time and money.

How Much Does it Cost in Colorado?

Adult adoption is generally the most affordable type of adoption since it rarely involves contested litigation.

How Long Does the Process Take?

Because there are no mandatory waiting periods or background checks required by the state, the timeline is extremely fast. Once the petition is filed in a Colorado District Court, the entire adult adoption process usually takes only 45 to 90 days, depending entirely on the local judge's calendar availability for the final hearing.
