The Adoption Process Step by Step

The adoption process typically takes 6 months to 3 years from initial application to finalization, depending on the type of adoption you pursue. Domestic infant adoption generally takes 1 to 3 years. Foster care adoption averages 1 to 2 years. Stepparent adoption can be completed in as little as 3 to 6 months. International adoption timelines vary widely by country but typically range from 2 to 4 years.

Regardless of the path you choose, every adoption follows a general sequence: application, home study, matching or placement, a supervised waiting period, and legal finalization. This guide walks through each stage, covers the four main types of adoption, breaks down costs, and explains what to expect legally and practically at every step.

Types of Adoption

The type of adoption you pursue shapes the timeline, cost, legal requirements, and overall experience. Understanding the differences helps you choose the path that best fits your family’s situation.

Domestic Infant Adoption

Domestic infant adoption involves adopting a newborn or young infant placed by a birth parent (or birth parents) in the United States. It is typically facilitated through a licensed adoption agency or an adoption attorney.

• Timeline: 1 to 3 years, primarily due to the wait for a match with a birth parent.
• Cost: $20,000 to $50,000, including agency fees, legal fees, birth parent expenses (where permitted by state law), and home study costs.
• Open vs. closed: Most domestic infant adoptions today involve some degree of openness, meaning the adoptive family and birth parent(s) maintain contact. Fully closed adoptions with no identifying information shared are less common than they were a generation ago.

Birth parents voluntarily place their child for adoption and must give legal consent, which cannot occur until after the child is born. The waiting period before consent becomes irrevocable varies by state — from 24 hours to 30 days after birth.

Foster Care Adoption

Foster care adoption involves adopting a child from the public child welfare system. These are children whose birth parents’ rights have been terminated by the court, usually due to abuse, neglect, or abandonment.

• Timeline: 1 to 2 years from the time you are licensed as a foster parent and matched with a child. Some families foster a child first, and the case transitions to adoption.
• Cost: $0 to $3,000. Foster care adoption is heavily subsidized by the state. Most families pay little or nothing out of pocket, and many children qualify for ongoing adoption subsidies, Medicaid, and educational benefits.
• Ages of children: Most children available for adoption through foster care are older — typically ages 3 and up. Sibling groups and children with special needs are more common than infants.

There are approximately 110,000 to 120,000 children in the U.S. foster care system with a goal of adoption at any given time. Foster care adoption serves both the child’s need for a permanent family and the adoptive parents’ desire to grow their family at a significantly lower cost.

International Adoption

International adoption involves adopting a child from another country. It is governed by both U.S. federal law and the laws of the child’s country of origin.

• Timeline: 2 to 4 years, depending on the country. Some countries have periodically closed their adoption programs or imposed moratoria, which can add delays.
• Cost: $25,000 to $55,000, including agency fees, dossier preparation, travel expenses, immigration processing, and legal fees in both countries.
• Requirements: The U.S. requires compliance with either the Hague Convention on Intercountry Adoption (for Hague Convention countries) or the orphan process (for non-Hague countries). Both involve extensive documentation, background checks, and immigration petitions.

International adoption has declined significantly since the mid-2000s, dropping from about 23,000 adoptions per year in 2004 to fewer than 2,000 per year in recent years, as many countries have tightened restrictions or closed programs.

Stepparent Adoption

Stepparent adoption occurs when a married person legally adopts their spouse’s child from a prior relationship. It is the most common type of adoption in the United States.

• Timeline: 3 to 6 months in most states, assuming the noncustodial birth parent consents or their rights are terminated.
• Cost: $1,500 to $5,000 for legal fees and court costs. Some states require a home study; others waive it for stepparent adoptions.
• Key requirement: The noncustodial birth parent must either voluntarily consent to the adoption or have their parental rights terminated by the court. If the birth parent objects, the process becomes significantly more complex and may require proving grounds for involuntary termination (such as abandonment or failure to support the child).

Adoption Requirements and Eligibility

Each type of adoption has specific eligibility requirements, but most share common criteria.

General requirements across most states and agencies:

• Minimum age of 21 (some states allow 18; some agencies require 25)
• Financial stability sufficient to support a child (you do not need to be wealthy)
• No disqualifying criminal history (felony convictions involving violence, abuse, or sexual offenses are disqualifying in all states; other felonies may be evaluated case by case)
• Stable housing with adequate space for a child
• Physical and mental health sufficient to parent

Who can adopt:

• Married couples (opposite-sex and same-sex couples are eligible in all 50 states)
• Single individuals (permitted in all states, though some agencies have preferences)
• Unmarried couples (laws vary by state; some require joint petitions, others allow one partner to adopt)

What is NOT required:

• Home ownership (renters can adopt)
• A specific income level (courts look for stability, not wealth)
• Religious affiliation (though some faith-based agencies have their own policies)
• Prior parenting experience

The Home Study Process

The home study is the most involved step in the adoption process and is required for nearly every type of adoption. It is conducted by a licensed social worker and serves as both an evaluation and an educational experience.

What the Home Study Includes

1. Background checks. Federal and state criminal background checks, child abuse registry checks, and sex offender registry checks for all adults in the household. Fingerprinting is typically required.

2. Interviews. Individual and joint interviews with all prospective adoptive parents. The social worker asks about your childhood, your relationship, your parenting philosophy, your motivation to adopt, and how you plan to address issues specific to adoption (such as discussing the child’s birth family).

3. Home inspection. The social worker visits your home to verify that it is safe and has adequate space for a child. They check for working smoke detectors, secure storage for medications and firearms, and general cleanliness. This is not a white-glove inspection — it is a safety check.

4. References. You will need to provide 3 to 5 personal references (not family members) who can speak to your character and suitability as parents.

5. Financial review. You must provide documentation of income, expenses, debts, and insurance coverage. Again, the goal is stability, not wealth.

6. Medical statements. Each prospective parent must provide a physician’s statement confirming general physical and mental health.

7. Education. Most agencies and states require prospective adoptive parents to complete a training program covering topics such as attachment, trauma-informed parenting, transracial adoption (if applicable), and the child’s developmental needs.

The home study typically takes 2 to 4 months from start to finish and costs $1,500 to $3,500. It remains valid for 1 to 2 years, after which an update is required.

Adoption Costs Breakdown

Adoption costs vary dramatically by type. The following table provides realistic ranges based on current data.

Financial assistance options:

• Federal adoption tax credit: Up to $16,810 per child (2025 figure; adjusted annually for inflation). Available for qualified adoption expenses.
• Employer adoption benefits: Many large employers offer adoption assistance programs ranging from $2,000 to $25,000.
• Adoption subsidies: Children adopted from foster care often qualify for monthly subsidies, Medicaid, and educational assistance that continue until age 18 (or 21 in some states).
• Grants and loans: Organizations like the National Adoption Foundation, Gift of Adoption Fund, and Help Us Adopt offer grants ranging from $2,500 to $15,000.

Legal Finalization and Post-Adoption

The Finalization Hearing

Adoption becomes legal at the finalization hearing, a court proceeding where a judge issues the final adoption decree. This hearing typically occurs after a mandatory waiting period following placement:

• Domestic infant: 3 to 12 months after placement, depending on the state.
• Foster care: 6 to 12 months after the child is placed in your home with an adoption goal.
• International: Many international adoptions are finalized in the child’s country of origin, but some families complete a re-adoption or recognition proceeding in their U.S. state court.
• Stepparent: 1 to 3 months after filing the petition, in most cases.

At the hearing, the judge reviews the home study, any post-placement reports, and the consent of all required parties. In most cases, the hearing is brief (15 to 30 minutes) and ceremonial in nature. Many courts encourage families to bring cameras and celebrate the occasion.

Once the adoption is finalized:

• The adopted child becomes your legal child with all rights and responsibilities of a biological child.
• A new birth certificate is issued listing the adoptive parents.
• The child inherits from the adoptive parents and vice versa.
• The birth parents’ legal rights and obligations are permanently terminated.

Post-Adoption Considerations

Post-placement supervision. Most agencies and courts require post-placement visits by a social worker before finalization. These visits verify that the child is adjusting well and that the placement is stable. Expect 2 to 4 visits over the first 6 to 12 months.

Post-adoption support. Many adoptive families benefit from ongoing support, including:

• Adoption-competent therapists who understand attachment and identity issues
• Support groups for adoptive parents and adopted children
• Educational resources on talking to your child about their adoption story
• Cultural connections for children adopted from other countries or across racial lines

Identity and records. Laws regarding an adopted person’s access to their original birth certificate and adoption records vary by state. Some states have moved toward open records, allowing adult adoptees to access their original birth certificates without restriction. Others maintain sealed records that require a court order to open.

What to Do Next

Adoption is a deeply rewarding process, but it is also legally complex and emotionally demanding. Starting with the right information and the right team makes a meaningful difference.

1. Research the type of adoption that fits your family. Consider your timeline, budget, preferences regarding the child’s age, and your comfort level with openness. There is no single “best” path — only the one that works for your situation.
2. Attend an informational session. Most adoption agencies offer free orientation sessions that walk you through their process, fees, and requirements. Attend sessions with multiple agencies before committing.
3. Begin gathering documents. The adoption process is paperwork-intensive. Start collecting birth certificates, marriage certificates, financial statements, and medical records early to avoid delays.
4. Prepare your household. Ensure your home meets basic safety requirements and that you have adequate space. Address any issues (such as securing medications or installing smoke detectors) before the home study.
5. Consult an adoption attorney. Adoption law varies by state and by adoption type. An attorney who specializes in adoption can explain your state’s specific requirements, review agency contracts, and represent you in court. Schedule a free consultation to discuss your next steps.
