You can adopt a child without being married. Every U.S. state allows single people to adopt, and no state treats being unmarried as a reason, by itself, to deny an adoption. Unmarried couples can also adopt together in many states, though the mechanics depend on where you live. In every case, the legal standard is the best interest of the child, meaning courts look at stability, resources, and your ability to provide a safe home rather than whether you have a spouse.
Legal Standing of Unmarried Adoptive Parents
No federal or state law bars a single person from adopting. There isn’t a single federal statute banning marital-status discrimination in adoption, but the working consensus across all 50 states is that unmarried status alone is not enough to reject a petition.
The meaningful distinction is between public and private agencies. State-run child welfare agencies cannot turn applicants away because they are unmarried. Private agencies set their own placement preferences, and some favor two-parent households. Plenty of private agencies actively welcome single applicants, so ask directly about an agency’s placement history with single parents before you commit.
Once a court issues the final adoption decree, a single adoptive parent holds exactly the same legal rights and responsibilities as any other parent: authority over education, healthcare, and upbringing, plus inheritance rights, Social Security eligibility, and every other legal protection that flows from parentage. The relationship is legally identical to a biological one.
Adopting as an Unmarried Couple
Many people asking this question aren’t single. They’re in a committed relationship without a marriage certificate. The rules here are less uniform than they are for solo adopters.
Some states allow unmarried couples to file a joint adoption petition, so both partners become legal parents from the start. Others limit joint petitions to married couples, which means only one partner can petition initially.
In states that don’t allow joint petitions by unmarried couples, second-parent adoption is the workaround. One partner adopts as a single parent, and the other partner then petitions separately to adopt the same child without the first parent losing any rights. The process resembles stepparent adoption and is available in a growing number of states, including Colorado, Connecticut, Illinois, Indiana, Maine, and Massachusetts. The second adoption requires its own home study, background check, and court approval, which adds time and cost.
If you’re an unmarried couple, confirm what your state permits before you start. An adoption attorney in your jurisdiction can tell you whether a joint petition is possible or whether you’ll need the two-step approach. Letting only one partner adopt without a plan to secure the other’s legal status can leave the non-adoptive partner with no rights if the relationship later ends.
Requirements You’ll Need to Meet
The baseline requirements are the same ones any prospective parent faces. A few areas get extra scrutiny when there’s no second parent in the picture.
Age
Minimum ages vary by state. Many set the floor at 18, others at 21. International adoption is stricter: unmarried U.S. citizens must be at least 25 to adopt from another country, regardless of the sending country’s own rules.1U.S. Department of State. Who Can Be Adopted
Financial Stability
You don’t need to be wealthy, but you do need consistent income that can support another person. Agencies and courts verify this through tax returns, bank statements, and employment records. For single applicants, evaluators focus on whether your budget has enough room to absorb the unpredictable costs of raising a child on one income. Savings, stable employment, and manageable debt matter more than any specific salary.
Health and Background Checks
You’ll need a physician’s statement confirming you’re healthy enough to care for a child into adulthood. Mental health is part of that assessment, but a history of treatment for anxiety or depression won’t automatically disqualify you. Evaluators are looking for stability and self-awareness.
Background checks are federally mandated for anyone adopting through foster care. A felony conviction for child abuse, crimes against children, sexual assault, or other violent crimes is an automatic disqualifier. Felony convictions for physical assault, battery, or drug offenses within the past five years also bar approval.2GovInfo. 42 USC 671 – State Plan for Foster Care and Adoption Assistance States must also check child abuse and neglect registries in every state where you’ve lived during the preceding five years.3U.S. Citizenship and Immigration Services. Background Checks – Security and Child Abuse Registry
Support Network
This is where single applicants face the most pointed questions. Courts and agencies want to see reliable people who can step in during emergencies, help with childcare, and provide emotional support. You’ll typically need to name specific individuals willing to fill these roles, and the social worker may interview them. Naming a legal guardian in your will is standard. If something happens to you, the court needs to know who would care for the child.
The Home Study
Every adoption in the United States requires a home study, regardless of type or marital status.4AdoptUSKids. Home Study A licensed social worker conducts the evaluation, which usually takes three to six months and includes interviews, home visits, and a document review.
As a single applicant, expect the interviews to dig into your motivation for adopting, your understanding of what solo parenting involves, and how you plan to manage work and childcare day to day. The social worker isn’t looking for someone with every answer ready. They want realistic expectations, emotional maturity, and a workable plan. Being upfront that solo parenting is hard actually helps. It shows you’ve thought about it.
The home visit checks that your space is safe and has room for a child. A large house isn’t required, but the space needs to be clean, childproofed, and include a dedicated sleeping area. The social worker then reviews finances, health records, references, and background checks before writing a final report with a recommendation.
If you’re working with a private agency or independent social worker, home study fees generally run $1,000 to $3,000.4AdoptUSKids. Home Study Public foster care agencies typically cover the cost themselves. The home study is valid for a limited period; if your adoption drags on, you may need an update.
Adoption Pathways for Single and Unmarried Applicants
Three main routes exist, each with different costs, timelines, and rules for unmarried applicants.
Foster Care Adoption
Adopting from public foster care is the most common route for single parents. Roughly three in ten foster care adoptions are completed by unmarried individuals, and most cost little to nothing because the state funds the process.5AdoptUSKids. What Does It Cost Many children adopted from foster care also qualify for ongoing adoption assistance, including monthly maintenance payments and medical coverage that can continue until the child turns 18, or 21 in some states.
Children available through foster care tend to be older, part of sibling groups, or have special needs. Agencies are often actively recruiting parents for these placements, so the process can move faster if you’re open to these circumstances. Many of these children have experienced trauma, and single applicants need to be honest with themselves about the level of support they can offer.
Private Domestic Adoption
Private domestic infant adoption typically costs between $20,000 and $45,000, covering agency fees, legal costs, birth-parent counseling, and sometimes medical expenses. Birth parents choose the adoptive family, and some prefer two-parent households. Others specifically select single adopters for reasons that matter to them, whether that’s parenting philosophy, religious alignment, or a personal sense of fit.
Wait times are unpredictable. Some single applicants match within months, others wait years. Working with an agency experienced in placing children with single parents improves your odds. Birth-parent consent timelines also vary by state. Some make consent irrevocable almost immediately when given before a judge, while others provide a revocation window of several weeks.
International Adoption
International adoption is open to single U.S. citizens, but the rules depend almost entirely on the child’s country of origin. Under U.S. immigration law, an unmarried person must be at least 25 to bring an adopted child into the country.1U.S. Department of State. Who Can Be Adopted Beyond that threshold, each country sets its own criteria. Colombia, India, and Bulgaria accept single adopters of both sexes. China and the Philippines allow only single women. A number of countries limit international adoption to married couples entirely.
International adoptions also involve immigration processing through USCIS, which brings its own background checks, paperwork, and fees.6U.S. Citizenship and Immigration Services. Immigration through Adoption Total cost typically runs $25,000 to $50,000 or more, and the timeline is one to three years. Country programs also change frequently. A country accepting single adopters today may close that option tomorrow.
Costs and Financial Assistance
Costs vary widely by pathway. Foster care adoption is generally free. Private domestic adoption runs roughly $20,000 to $45,000. International adoption can exceed $50,000. Several forms of financial help apply regardless of which route you take.
Federal Adoption Tax Credit
The federal adoption tax credit lets you claim qualified adoption expenses, including agency fees, attorney fees, court costs, and travel, against your tax liability. The credit is adjusted annually for inflation. For the 2026 tax year, the maximum is approximately $17,670 per child. The credit phases out at higher incomes, starting to reduce when your modified adjusted gross income exceeds roughly $265,000 and disappearing above approximately $305,000.7Office of the Law Revision Counsel. 26 USC 23 – Adoption Expenses
If you adopt a child with special needs from foster care, you can claim the full credit even if your actual expenses were lower. Starting in tax year 2025, up to $5,000 of the credit is refundable, meaning you can receive it even if you owe no federal income tax.8Internal Revenue Service. Adoption Credit The remaining portion is nonrefundable but can be carried forward.
Employer Adoption Assistance
Some employers offer adoption assistance programs that reimburse qualifying expenses. For 2026, up to $17,670 in employer-provided adoption assistance can be excluded from your taxable income. You can use both the employer exclusion and the tax credit for the same adoption, but not on the same dollar of expense.
Foster Care Adoption Subsidies
Children adopted from foster care who are classified as having special needs may qualify for ongoing federal adoption assistance under Title IV-E, including monthly payments and Medicaid coverage.5AdoptUSKids. What Does It Cost The “special needs” designation is broader than it sounds and can apply based on age, sibling group membership, race or ethnicity, or a medical condition. Monthly payment amounts vary by state and typically track the child’s level of care needs. Benefits generally continue until age 18, with extensions available in some states through age 21.
Parental Leave After Placement
Adoptive parents have the same right to family leave as biological parents under federal law. The Family and Medical Leave Act entitles eligible employees to 12 weeks of unpaid, job-protected leave after a child is placed for adoption.9Office of the Law Revision Counsel. 29 USC 2612 – Leave Requirement To qualify, you must have worked for a covered employer for at least 12 months, logged at least 1,250 hours during that period, and work at a location where the employer has at least 50 employees within 75 miles.10U.S. Department of Labor. Fact Sheet 28 – The Family and Medical Leave Act
FMLA leave is unpaid, and many single adopters can’t afford three months without income. Check whether your state runs a paid family leave program. A growing number do, and they typically cover adoption placement alongside birth. Some employers also offer paid parental leave, so review your company’s policy early.
Federal employees get more. The Federal Employee Paid Leave Act provides up to 12 weeks of paid parental leave following an adoption placement, to be used within 12 months of placement, with a written agreement to return to work for at least 12 weeks afterward.11U.S. Department of Labor.
