Yes, a single person can adopt a child in every U.S. state. No state law requires adoptive parents to be married, and single adults now complete more than a quarter of all foster care adoptions. What varies is not whether you’re eligible but which path you choose: foster care, private domestic, international, or independent adoption each carry different costs, timelines, and, in some cases, different attitudes toward unmarried applicants.
What You Need to Qualify
Every adoption asks the same basic question: can you provide a safe, stable home for a child? The specifics vary by agency and state, but the core requirements are consistent.
Most states and agencies set the minimum age at 21. A few use 18 or 25. Some international programs also impose upper age limits or require a minimum age gap between parent and child. There is no universal maximum age for domestic adoption.
You don’t need to be wealthy, but you must show you can support a child. Agencies typically ask for tax returns, pay stubs, and a basic statement of assets and debts. Foster care agencies tend to apply more flexible income thresholds than private agencies placing infants.
A physical exam completed within the past 12 months is standard, and many agencies require tuberculosis testing for every member of the household. You’ll also discuss your psychological readiness during home study interviews, and some agencies require a formal mental health evaluation.
Criminal history and child abuse registry clearances are mandatory. All adults living in the household are screened through both state and federal databases. If you’ve lived in another state within the past five years, expect the agency to pull records from that state’s child abuse registry too.
The Home Study
The home study is the gatekeeping step in any adoption. A licensed social worker interviews you in depth, visits your home, and writes a formal evaluation of your readiness to parent. Expect several visits spread over weeks or months.
On the home visit itself, the social worker checks that your living space is safe and has adequate room for a child. Working smoke detectors, safe storage for medications and cleaning supplies, and a reasonable sleeping arrangement are the kinds of things they look for. Nobody expects a magazine-worthy house.
The interview portion goes deeper. The social worker wants to understand your support network, your grasp of adoption-related challenges, and how you plan to handle parenting alone. Single applicants should expect pointed questions about backup childcare and how they’ll manage without a co-parent. That isn’t a red flag. It’s the social worker doing their job, and it’s the same question a thoughtful friend would ask.
Home study fees generally run $1,000 to $5,000, depending on your location and the agency conducting it. In foster care adoptions, the home study is often provided at no cost through the public child welfare agency.
Which Type of Adoption Works Best for Single Applicants
Foster Care Adoption
Foster care is the most accessible and affordable path for single parents, and it’s the one where the system most clearly works in your favor. Public agencies need adoptive parents and evaluate you on your ability to meet a child’s needs, not your marital status. They actively recruit single adults.
Over 100,000 children in U.S. foster care are waiting for permanent families. The process typically takes 6 to 18 months from initial training to finalization. Most children available through foster care are older, from toddlers through teenagers, and many are part of sibling groups.
The cost is minimal. Most public agencies charge nothing or only nominal fees, and many states cover the home study and training expenses entirely. Children who meet the federal definition of “special needs” (which broadly includes older children, sibling groups, children with disabilities, and children who are hard to place for other reasons) may qualify for ongoing monthly adoption assistance payments and automatic Medicaid coverage that continues regardless of the adoptive family’s income.1Medicaid.gov.

Private Domestic Adoption
Private agencies match prospective parents with expectant birth parents planning to place their newborns for adoption. Birth parents typically have a role in choosing the adoptive family, which is where single applicants sometimes face headwinds. Many birth parents prefer couples, and some private agencies quietly steer toward married applicants. Others welcome single applicants and have a track record of placements, and those agencies aren’t hard to find if you ask directly how many single-parent placements they’ve completed recently.
This path is significantly more expensive and slower than foster care. Total costs commonly range from $40,000 to $60,000, covering agency fees, legal expenses, birth parent counseling, and sometimes the birth mother’s medical or living costs. Wait times for a match can stretch from two to seven years.
International Adoption
International adoption is where single status creates the most concrete obstacles, because restrictions are written into foreign law rather than left to agency discretion. Many sending countries restrict or prohibit single-parent adoptions outright.
China effectively ended international adoptions for non-Chinese nationals in 2024. Russia has banned adoptions by citizens of countries that recognize same-sex marriage, which blocks most Americans. Among countries still accepting single applicants, some impose gender-based rules; India, for example, allows single men to adopt only boys. Colombia and Bulgaria remain open to single women and, with restrictions, single men.
Beyond the country’s own laws, you must also satisfy U.S. requirements. For countries party to the Hague Adoption Convention, you must first be approved by U.S. Citizenship and Immigration Services by filing Form I-800A before any child can be matched to you.2Travel – State Department. Convention Adoption Process The State Department must also issue a formal letter to the foreign government before you can obtain custody. Costs generally run $25,000 to $60,000 or more, depending on the country, plus travel expenses for one or two required trips.
Independent Adoption
Independent adoption bypasses agencies. You work directly with a birth parent, typically with attorneys representing both sides. It offers more flexibility in how the match happens but less institutional support. Not every state permits it, and where it is allowed the legal requirements vary considerably. An attorney experienced in adoption law is essential; independent adoption without proper legal guidance is where things go wrong most often.
What It Costs and What Help Exists
Adoption costs span an enormous range. Foster care adoption typically costs $0 to $5,000. International adoption generally runs $25,000 to $60,000 plus travel. Private domestic infant adoption is the most expensive at $40,000 to $60,000. These figures include agency fees, legal costs, home study expenses, and court filing fees.
Several forms of financial help can offset the out-of-pocket cost.
For tax year 2025, the federal adoption tax credit covers up to $17,280 in qualified adoption expenses per child. Up to $5,000 of that credit is refundable, meaning you can receive it even if you owe no federal income tax. The full credit is available if your modified adjusted gross income is $259,190 or less; it phases out between $259,191 and $299,189 and disappears entirely above $299,190.3Internal Revenue Service. Adoption Credit These figures are adjusted annually for inflation, so verify the current year’s numbers on the IRS site when you file.
Some employers offer adoption reimbursement, with the average benefit around $15,600 per adoption at companies that provide it. Employer-paid adoption assistance can be excluded from your taxable income up to the same dollar limit as the tax credit, and the exclusion isn’t subject to federal income tax withholding, though Social Security and Medicare taxes still apply.
If you adopt a child with special needs from foster care, federal Title IV-E adoption assistance can provide monthly maintenance payments and automatic Medicaid eligibility for the child. There is no income test for the family; eligibility is based entirely on the child’s circumstances.1Medicaid.gov.

Where Being Single Actually Slows Things Down
Legally, being single is not a barrier anywhere. Practically, it can extend your timeline in two places.
In private domestic adoption, birth parents often prefer couples. Some agencies technically accept single applicants but prioritize married couples in matching. You won’t always be told this directly, which is why it’s worth asking agencies up front how many single-parent placements they’ve completed in the past few years and how long those matches took.
In international adoption, the barrier is legal rather than preferential, and the number of countries open to single adoptive parents has shrunk significantly in recent years. Those still open often impose gender-specific rules or longer wait times for unmarried applicants.
Foster care is the outlier. Marital status carries almost no weight there because agencies are focused on finding families for children who need them.
Leave and Insurance After Placement
Two federal protections kick in the moment a child is placed in your home. Miss the deadlines and you lose coverage or leave time.
The Family and Medical Leave Act entitles eligible employees to 12 weeks of unpaid, job-protected leave following placement of a child for adoption or foster care.4Office of the Law Revision Counsel. 29 U.S. Code 2612 – Leave Requirement You qualify if you’ve worked for a covered employer for at least 12 months, logged at least 1,250 hours during the previous year, and work at a location with 50 or more employees within 75 miles.5United States Department of Labor. Fact Sheet 28B – Using FMLA Leave When You Are in the Role of a Parent As a single parent you’re entitled to the full 12 weeks; the spousal sharing rule that can limit married couples to a combined 12 weeks doesn’t apply to you.6eCFR. 29 CFR 825.121 – Leave for Adoption or Foster Care Your right to take this leave expires 12 months after placement.
Adoption also triggers a special enrollment period for health insurance. If you have an employer-sponsored plan, you must notify your plan within 30 days of placement to add the child. If you use a Health Insurance Marketplace plan, the window is 60 days. In both cases, the child’s coverage is retroactive to the date of placement.7United States Department of Labor.
