Adult adoption in New York is a court proceeding under Article 7 of the Domestic Relations Law that creates a full legal parent-child relationship between two adults. It is faster and simpler than adopting a minor: no home study, no birth-parent consent, and usually one short hearing. The adoptee inherits from the adoptive parent as a biological child would. What the process does not do is just as important, especially around immigration, health insurance, and federal leave rights.
Who Can File and Who Can Be Adopted
The statute is broad about who can petition. An unmarried adult, a married couple filing together, or two unmarried intimate partners can all adopt another person.1New York State Senate. New York Domestic Relations Law 110 – Who May Adopt; Effect of Article There is no fixed age gap required by DRL §110, though judges look for a relationship that resembles a natural parent-child dynamic, so a meaningful age difference helps in practice.
A married person generally has to file jointly with their spouse. Filing alone is allowed only if the couple is living apart under a separation decree, a written separation agreement, or has been living separately for at least three years before filing. When that happens, the adoptee is not treated as the nonadopting spouse’s child for inheritance, support, or any other purpose.1New York State Senate. New York Domestic Relations Law 110 – Who May Adopt; Effect of Article
On the other side of the petition, the adoptee must be 18 or older. Once they are, only their own consent matters. Birth parents are not notified and their consent is not required.2New York State Senate. New York Domestic Relations Law 111 – Whose Consent Required That is a large part of why adult cases move so quickly compared to minor adoptions.
What the Judge Wants to See
Adult adoption petitions are not rubber-stamped. The court looks at whether the relationship is genuinely filial, meaning it functions like a parent-child bond rather than a romantic partnership, a business arrangement, or a workaround for something the law does not otherwise permit. In Matter of Robert Paul P., the Court of Appeals rejected an attempt by one partner to adopt the other, stating that adoption “is plainly not a quasi-matrimonial vehicle to provide nonmarried partners with a legal imprimatur for their sexual relationship.”3CaseMine. Matter of Robert Paul P
The relationships judges typically approve include informal stepparent situations that were never legally recognized, long-term guardians or mentors who raised the adoptee from a young age, and chosen-family arrangements where one adult has functioned as a parent figure over years. Your petition should tell that story: how you met, how the relationship developed, and why formalizing it matters now. Vague or purely financial motivations invite skepticism.
The Paperwork and the Hearing
The core filings are the Petition for Adoption, the adoptee’s written consent, the adoptive parent’s spouse’s consent if applicable, and a Verified Schedule with the adoptive parent’s background details. The Unified Court System publishes a standardized adult adoption petition (Form 29a) on its website.4New York State Unified Court System. Adoption Form 29a – Petition for Adult Adoption You will also need identity documents for both parties: birth certificates, government-issued photo IDs, and Social Security cards. Incomplete or inconsistent paperwork is the most common reason a case stalls.
Home studies are not required. DRL §112’s investigation provisions focus on protecting children, and courts generally do not order them for adults. Some counties impose a criminal background check and fingerprinting under local rules, which typically runs around $100 where required.
You file in either Family Court or Surrogate’s Court in the county where the adoptive parent lives. Filing fees are modest, generally somewhere between $20 and $90 depending on the venue. After filing, the court sets a hearing. For an uncontested case, the hearing is brief: both parties appear, the judge confirms consent and asks about the relationship, and if satisfied, signs the Order of Adoption on the spot. That order finalizes everything.
If the adoptee wants a name change, ask for it in the petition itself. DRL §114 lets the judge order the name change inside the adoption order, so a separate name-change proceeding is unnecessary.5New York State Senate. New York Domestic Relations Law 114 – Order of Adoption
What Changes for Inheritance
This is the most consequential effect of the whole process. Once the Order of Adoption is signed, the adoptee and adoptive parent have full mutual inheritance rights, identical to a biological parent and child. The adoptee inherits from the adoptive parent, through the adoptive parent’s relatives, and alongside any other children.6New York State Senate. New York Domestic Relations Law 117 – Effect of Adoption
The trade-off is real. DRL §117 also states that once the adoption order is made, the birth parents lose all parental rights and duties, and the adoptee’s right to inherit from birth parents ends.6New York State Senate. New York Domestic Relations Law 117 – Effect of Adoption There is one carve-out: in stepparent adoptions, where a birth parent consents to their spouse adopting the child, that consenting parent’s relationship and inheritance rights stay intact.
Adopted adults are also treated as biological children under class-gift language in wills and trusts. EPTL §2-1.3 includes them automatically when a document leaves property to someone’s “children” or “descendants.”7New York State Senate. New York Estates, Powers and Trusts Law 2-1.3 – Adopted Children That is one of the main reasons people pursue adult adoption in the first place: to give a chosen family member the same standing as a biological heir, on stronger legal ground than a will alone, which can be challenged.
If the adoptee still expects to inherit from biological relatives, run through the numbers with an estate planning attorney before filing. Signing the adoption order can wipe out those expectations.
What Adult Adoption Will Not Do
This is where expectations most often collide with the law. An adoption order changes state parent-child status, but several federal programs define “child” in ways that exclude someone adopted after 18.
Immigration
Federal immigration law requires that an adoption be finalized before the child’s 16th birthday for the adoptee to qualify as a “child” who can be petitioned. A narrow sibling exception reaches to age 18, but there is no exception for adoptions at 18 or older.8U.S. Citizenship and Immigration Services. Policy Manual Volume 5 Part E Chapter 2 – Eligibility An adult adoption in New York carries no immigration weight. A U.S. citizen cannot sponsor an adult adoptee for a green card based on the adoption.
FMLA Leave
The Family and Medical Leave Act defines “son or daughter” as a biological, adopted, or foster child who is either under 18 or over 18 and incapable of self-care due to a disability. A healthy adult adoptee does not qualify, so an adoptive parent generally cannot take FMLA leave to care for them. The definition of “parent” runs in the other direction as well: it covers someone who stood in loco parentis to the employee during the employee’s childhood, so the adoptee cannot take FMLA leave to care for the adoptive parent unless that parental relationship existed while the adoptee was a child.9Office of the Law Revision Counsel. 29 USC 2611 – Definitions
Health Insurance
The Affordable Care Act requires health plans to cover dependents up to age 26, and adopted children qualify. If the adoptee is already 26 or older, that mandate does not help. New York’s Young Adult Option extends eligibility through age 29 for children of parents in group health plans, but only if the young adult is unmarried and not eligible for their own employer-sponsored coverage. Above 29, dependent coverage is generally not available.
Reversing an Adoption
Reversal is possible but hard. DRL §114 lets the issuing court “open, vacate or set aside” an adoption order for fraud, newly discovered evidence, or other sufficient cause.5New York State Senate. New York Domestic Relations Law 114 – Order of Adoption Changing your mind or falling out with the other party does not meet that standard. Courts treat adoption as permanent and set a high bar. If either party has doubts about permanence, resolve them before filing.
What It Costs
Adult adoption is among the cheaper legal proceedings you can file. Court filing fees run roughly $20 to $90 depending on the court and county. Add about $100 for fingerprinting if your county requires it. The petition forms are free from the court system’s website.
The bigger variable is the lawyer. Many people handle uncontested cases themselves with the standardized forms. If you hire an attorney for a straightforward, uncontested case, total legal fees typically run a few thousand dollars. Contested proceedings, interstate complications, or estate plans that need to be restructured around the adoption cost more.
