Yes, you can adopt as a single parent in every U.S. state. No federal or state law requires adoptive parents to be married, and single-parent adoptions have grown steadily, by some estimates accounting for more than a quarter of all foster care adoptions. You’ll go through the same core steps any adoptive parent faces: meeting eligibility rules, passing a home study, and getting a court decree. The one place single status creates real extra friction is international adoption, where certain sending countries impose stricter rules on unmarried applicants.
Basic Eligibility
Age comes first. Most states set the minimum at 18, though some require 21 or 25. Federal immigration law goes further for international cases: an unmarried U.S. citizen must be at least 25 to bring an adopted child into the country, no matter where the child is from.1U.S. Department of State. Who Can Be Adopted That federal age floor sits on top of whatever your state requires.
You’ll also need to be a legal resident of the state where you file. More than 15 states require residency anywhere from 60 days to a full year before you can petition. You must be legally competent, meaning no court has declared you unable to manage your own affairs or care for dependents.
Citizenship is not a blanket requirement for adopting domestically. Lawful permanent residents can adopt under state law, and even certain nonimmigrant visa holders may qualify depending on the state.2U.S. Department of State. Adoption by Non-U.S. Citizens Living in the United States International adoption, however, does require U.S. citizenship because the process involves immigration petitions for the child.3U.S. Department of State. Who Can Adopt
One claim circulating online is that the Civil Rights Act protects single adoption applicants from discrimination. It doesn’t. That law covers employment discrimination based on race, color, religion, sex, and national origin. The federal Multiethnic Placement Act prohibits race-based discrimination in foster and adoption placements, but no federal statute specifically bars agencies from considering marital status. In practice, most agencies welcome single applicants. Private agencies with religious affiliations occasionally prefer married couples, which is worth asking about before you commit.
Adoption Paths and How They Affect Single Applicants
The route you pick drives your timeline, your costs, and which rules apply. Each path lands differently on a single-income household.
Foster Care Adoption
Adopting from foster care is typically the least expensive option. Many states charge little or nothing for the adoption itself, and the federal government reimburses up to $2,000 in nonrecurring expenses — court costs, attorney fees, travel — per child with special needs.4Child Welfare Policy Manual. Title IV-E Adoption Assistance Program – Non-Recurring Expenses Children adopted from foster care who meet special needs criteria may also qualify for monthly adoption assistance subsidies continuing until at least age 18, plus Medicaid coverage.
The trade-off is time and training. States require prospective foster-to-adopt parents to complete pre-service training, often 20 to 30 hours covering topics like trauma-informed parenting and attachment. You must be licensed as a foster parent before placement, and licensing itself can take several months. Children in foster care are frequently older, part of sibling groups, or have medical or emotional needs, which is why the financial supports exist.
Domestic Private Adoption
Private domestic adoption means working with a licensed agency or adoption attorney to match with a birth parent, usually for a newborn placement. Total costs commonly range from $30,000 to $65,000, covering agency fees, the birth parent’s legal representation, home study fees, and court costs. Some agencies impose their own minimum income or housing requirements beyond what state law demands, and those vary widely.
Birth parent consent sits at the center of this path. The biological parents’ rights must be legally terminated, either voluntarily or through court-ordered involuntary termination in cases of abuse or neglect. Most states set a waiting period after birth before a mother can sign a valid consent, and many allow a revocation window ranging from a few days to several weeks. This is where private adoption carries its sharpest risk: a birth parent who changes their mind during that window can legally reclaim the child, and prospective adoptive parents have limited recourse. An experienced adoption attorney is not optional.
International Adoption
International adoption is where single status matters most. Some countries flatly refuse to place children with unmarried adopters. Others allow it but impose stricter thresholds than they require of couples, such as a higher minimum age (sometimes 35) or a higher demonstrated net worth. These rules change frequently, so verifying current eligibility with an accredited agency before you invest in the process is essential. Total costs frequently run $25,000 to $50,000 or more depending on the country.
On the U.S. side, all adoption service providers must meet accreditation standards under the Hague Adoption Convention, overseen by the Department of State.5U.S. Department of State. The Role of the Accrediting Entity
The Home Study
Every adoption, whether foster, domestic, or international, requires a home study. It’s the single most important piece of your application and typically takes three to six months.6AdoptUSKids. Completing a Home Study A licensed social worker visits your home, interviews you and any other adults or children in the household, and writes a report recommending whether you should be approved.
The report generally covers:
- Background and references, including personal history, education, employment, and character references from people outside your family.
- Financial stability, confirmed through tax returns, pay stubs, or W-2 forms. The goal is to confirm you can support a child, not that you’re wealthy. Receiving government benefits does not automatically disqualify you.
- Health, documented by a physical exam within the past 12 months for all prospective parents, plus tuberculosis testing for everyone in the household.6AdoptUSKids. Completing a Home Study
- Criminal background and child abuse registry checks for all adults in the home. A conviction for harming a child is an absolute bar.
- A physical description of your home and neighborhood, including safety features.
- Parenting readiness, meaning your motivation to adopt, your parenting philosophy, how you handle discipline, and the type of child you feel prepared to parent.
Home study fees from private agencies typically run $1,000 to $3,000. For foster care adoptions, many states cover the cost entirely. An approved home study usually stays valid for one to two years, after which an update is required if you haven’t yet been matched.
For single applicants, expect social workers to spend extra time on your plan for childcare, emergencies, and support networks. The right answer is a realistic, concrete one. Strong references from friends, family, and colleagues who can speak to your character and your support system carry real weight here.
From Petition to Finalization
Once a child is placed and the required post-placement period has started, you file a formal adoption petition in your local family or probate court. Filing fees vary by jurisdiction, and many courts now accept or require electronic filing. The court may appoint a guardian ad litem, an attorney or trained volunteer who independently evaluates the case and recommends whether the adoption serves the child’s best interests.
Before scheduling finalization, most states require a series of post-placement visits by a social worker, typically around three spread over several months. The visits assess how the child is adjusting, whether the family is bonding, how any special needs are being addressed, and whether the home remains safe. International adoptions can carry additional post-placement reporting set by the child’s country of origin; the Philippines, for example, requires a six-month post-placement period with bi-monthly reviews before finalization can proceed.7U.S. Department of State. Post-Adoption Reporting Overview
The finalization hearing itself is usually brief and largely ceremonial if the file supports approval. The judge reviews the home study, post-placement reports, guardian ad litem recommendation, and any consent or termination-of-rights documents, then signs a decree of adoption. The court sends the decree to the state vital records office, which issues a new birth certificate listing you as the parent. From petition to signed decree, the process typically takes three to nine months.
A signed decree does more than give you custody. It creates the same legal parent-child relationship that exists between a biological parent and child. You gain full parental rights and responsibilities, and the child gains inheritance rights from and through you and your extended family. The birth parents’ legal rights and responsibilities end, and the child’s right to inherit from biological parents typically terminates on entry of the decree, with narrow exceptions in a handful of states. Once signed, the decree is permanent.
Costs, Tax Credit, and Leave
The federal adoption tax credit offsets a meaningful share of adoption expenses. For the 2026 tax year, the maximum credit is $17,670 per eligible child, covering qualified expenses such as attorney fees, court costs, travel, and agency fees. Up to $5,120 of the credit is refundable for 2026, meaning you get that portion back even if you owe no federal income tax.8Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Any nonrefundable portion you can’t use in the current year carries forward for up to five years.9Internal Revenue Service. Adoption Credit
The credit begins to phase out at a modified adjusted gross income of $265,080 and disappears entirely above $305,080 for 2026. If you adopt a child with special needs from U.S. foster care, you can claim the full credit amount even if your actual expenses were lower, or zero. You report the credit on IRS Form 8839.
Some employers also offer adoption assistance benefits. If your employer provides adoption reimbursement through a qualified program, that amount can be excluded from your taxable income up to the same $17,670 limit. Expenses covered by employer assistance cannot also be claimed for the tax credit.
The Family and Medical Leave Act entitles eligible employees to 12 workweeks of unpaid, job-protected leave for the placement of a child through adoption or foster care.10Office of the Law Revision Counsel. 29 U.S. Code 2612 – Leave Requirement To qualify, you must have worked for your employer at least 12 months, logged at least 1,250 hours in the previous year, and work at a location with 50 or more employees within 75 miles.11U.S. Department of Labor. Fact Sheet 28Q – Taking Leave from Work for Birth, Placement, and Bonding with a Child under the FMLA The leave must be taken within 12 months of placement. FMLA leave is unpaid at the federal level, but some states have paid family leave programs that cover adoptive parents, and individual employers may offer paid adoption leave.
What’s Different in Practice for Single Adopters
On paper, you check the same boxes as any married applicant. In practice, a few things play out differently.
Financially, the math is unforgiving. A single income means adoption costs hit harder, and the post-adoption adjustment period — reduced work hours, childcare expenses, possibly a bigger home — lands entirely on one budget. Running the numbers before you start, including the first two years of parenting expenses, is the most practical step you can take. The tax credit helps, but it arrives after you’ve already spent the money, sometimes a full tax year later.
Wait times also vary by path. Foster care placements can happen relatively quickly for applicants open to older children or sibling groups. Domestic infant adoption wait times for single parents tend to run longer than for couples, sometimes two years or more, because birth parents selecting an adoptive family often prefer a two-parent household. International adoption timelines depend on the specific country and can range from one to four years.
None of this changes the answer to the question you came in with. You can adopt as a single parent, in any state, through any of the three main paths. The work is in picking the path that fits your finances, your timeline, and the kind of child you’re prepared to parent, then documenting all of that clearly enough to satisfy a social worker and a judge.
