How Long Does the Adoption Process Take in Missouri?
Families considering adoption often want to know how quickly the process can be completed. The answer depends on the type of adoption, whether the required parties consent, how quickly background checks and assessments are completed, and whether legal complications arise.
In many Missouri cases, finalization takes at least six months after the child is lawfully placed with the prospective adoptive parents. However, the complete process may take several months to more than a year when preparation, placement, court filings, and post-placement supervision are included.
Understanding each stage can provide a clearer answer to the question: How long does the adoption process take in Missouri?
Why Adoption Timelines Vary
There is no single timeline that applies to every adoption. Missouri recognizes several adoption arrangements, including:
- Private infant adoption
- Stepparent adoption
- Relative or grandparent adoption
- Adoption from foster care
- Interstate adoption
- International adoption
- Adult adoption
A stepparent adoption involving full consent may move more quickly than an interstate or contested adoption. Foster care cases may take longer when parental rights have not yet been terminated or the child is not legally available for adoption.
The court must approve every adoption and determine that it serves the adopted person’s welfare. Therefore, completing forms alone does not guarantee immediate finalization.
The Initial Application and Preparation Stage
Prospective adoptive parents commonly begin by selecting an agency, identifying an adoption opportunity, or discussing a stepparent or relative adoption with legal counsel.
Families seeking to adopt through the Missouri Children’s Division must generally be at least 21 years old, complete criminal and child abuse background checks, demonstrate stable income and good health, and participate in training and assessment.
Training and Home Assessment
A home assessment, also called a home study, examines whether the prospective household is suitable for a child. It may involve:
- Interviews with household members
- Criminal and child abuse background checks
- Financial and employment information
- Medical records
- Personal references
- A home safety inspection
- Discussions about parenting and adoption expectations
Missouri’s Children’s Division states that home studies for families adopting through the state are generally initiated within 30 days after an application is received and completed within four months. Delays may occur when documents, references, medical records, or background checks are incomplete.
The home assessment and required state training are provided without charge to families adopting through the Children’s Division.
Consent and Parental Rights
Consent is one of the most important factors affecting the Missouri adoption timeline.
Missouri law generally requires the written consent of the child’s mother and certain legally recognized or qualifying fathers. Consent may not be required when a parent’s rights have already been terminated or another statutory exception applies.
A birth mother cannot legally execute adoption consent until the child is at least 48 hours old. Once properly executed, consent is generally final unless the consenting person proves before the final decree that it was not given freely and voluntarily.
A child who is 14 or older must ordinarily provide written consent to the adoption. For a younger child, the guardian ad litem—an individual appointed to represent the child’s interests—may interview the child and report the child’s wishes when appropriate.
When all required parties consent, the case may proceed relatively efficiently. When a biological parent cannot be located, refuses to consent, or contests the termination of parental rights, the case may take considerably longer. Additional hearings, formal service of court papers, investigations, and evidence may be required.
Filing the Adoption Case
The prospective adoptive parent files a petition in the appropriate Missouri court. The petition generally provides information about the child, petitioners, placement, biological parents, required consents, and the reasons the adoption serves the child’s best interests.
In cases involving an adoption assessment ordered by the court, Missouri’s Children’s Division explains that the investigation and report generally must be submitted within 90 days. A case may be delayed when the assessment is incomplete or the court requires additional information.
Courts may also appoint a guardian ad litem to protect the child’s interests during the proceeding.
Missouri’s Six-Month Placement Requirement
A major timing rule is Missouri’s six-month custody requirement. Before entering a final adoption decree, the court generally must find that the child has been in the lawful and actual custody of the petitioner for at least six months.
This does not necessarily mean that the adoption petition must wait six months before it is filed. Some legal steps can occur while the child is living with the prospective adoptive parents.
The court may waive the six-month period when the child is already under juvenile-court jurisdiction and the person adopting is the child’s current foster parent.
During the placement period, an adoption professional generally conducts post-placement contacts. The court reviews the post-placement assessment, financial information, recommendations from involved professionals, and compliance with applicable state and federal requirements before finalization.
How Long Different Adoptions May Take
Stepparent and Relative Adoptions
These cases can sometimes be completed more quickly because the child already lives with or has an established relationship with the petitioner. However, the case may still take several months when consent or parental-rights issues must be resolved.
Private Infant Adoptions
The timeline depends on locating a placement, completing the home study, obtaining valid consent after birth, transferring custody, and satisfying the post-placement period. The waiting period for a placement may be longer than the court process itself.
Foster Care Adoptions
The process may take longer when reunification with the biological family remains the child’s case goal. Adoption cannot generally proceed until the child is legally free for adoption. Once parental rights are resolved and a suitable foster family is already caring for the child, finalization may progress more efficiently.
Nationally, more than 330,000 children were in foster care in 2025, demonstrating the scale of the public child welfare system and the number of cases agencies and courts must manage.
Interstate Adoptions
When the child and adoptive parents live in different states, the Interstate Compact on the Placement of Children usually applies. Both states must approve the placement before the child can cross state lines for adoption purposes. This additional review can extend the timeline.
Factors That Commonly Cause Delays
An adoption may take longer because of:
- Missing or incomplete court documents
- Delayed background checks
- Difficulty locating a biological parent
- Contested consent or parental rights
- An incomplete home assessment
- Interstate approval requirements
- Changes in placement circumstances
- Crowded court calendars
- Requests for additional investigation
An adoption attorney may help identify which requirements apply to a particular type of adoption and ensure that filings, notices, consents, and hearing documents meet Missouri’s procedural rules.
Key Takeaways
How long the adoption process takes in Missouri depends on the type of adoption and the facts surrounding the child’s placement. Initial training and home assessment may require several months, and Missouri generally requires at least six months of lawful and actual custody before finalization.
Uncontested stepparent or relative adoptions may move more efficiently, while contested, foster care, interstate, and international cases often require additional time. Proper consent, complete assessments, lawful placement, post-placement supervision, and final court approval are all essential before an adoption becomes legally permanent.
