How to Adopt an Adult in Washington DC
Reviewed by DocDraft Legal Team · Washington DC · Last updated November 13, 2026
District of Columbia law needs only two things before a person over eighteen can be adopted: that person's consent, and a Family Court judge who is satisfied the adoption should be granted (D.C. Code 16-304(f)). Adult adoption is a court case that permanently makes one adult the legal parent of another adult, with the inheritance and next of kin consequences that follow. There is no category list and no minimum age gap. Any person may petition, and a person, whether a minor or an adult, may be adopted (16-302, 16-303). One rule deserves attention before any paperwork, and it concerns the petitioner's own marriage. A married petitioner's spouse must join the petition as a co-petitioner, unless that spouse is the adoptee's natural parent, who signs a consent instead (16-302). The adoptee's consent is a written statement, acknowledged before an officer authorized to take acknowledgments and filed with the petition (16-304(a)). For an adult, the court must dispense with the agency investigation, the report and the interlocutory decree (16-308(a)(1)), and the six month living together rule does not apply to an adoptee 18 or older (16-309(c)(2)). The case belongs in the Family Court of the Superior Court of the District of Columbia, which has jurisdiction when the petitioner is a legal resident of the District or has actually lived there for at least one year before filing (16-301(b)). The Family Court fee rule lists $80 for filing a petition, so confirm the amount with the clerk. Unless the decree says otherwise, the adoptee takes the adopter's family name (16-312(c)).

Who can be adopted as an adult in Washington DC?
A person over eighteen may be adopted on the petition of the adopting parent or parents, with that person's consent, if the court is satisfied the adoption should be granted (D.C. Code 16-304(f)). The District attaches no category list, no disability condition and no minimum number of years between the two adults.
Does my spouse have to join an adult adoption petition in Washington DC?
Usually yes. The court may not consider the petition unless the petitioner's spouse joins it (D.C. Code 16-302). The exception is a spouse who is the adoptee's natural parent: that parent need not join and only gives consent. If the petitioner's marital status changes before the final decree, the petition must be amended.
Is a home study required to adopt an adult in Washington DC?
No agency investigation is required. D.C. Code 16-308(a)(1) directs the court to dispense with the investigation, report and interlocutory decree when the prospective adoptee is an adult. Section 16-308(d) keeps the separate fingerprint based criminal records check rules in force, so ask the clerk whether a check applies to your case.
Which court handles adult adoption in Washington DC?
The Family Court of the Superior Court of the District of Columbia, which holds original jurisdiction over adoption proceedings (D.C. Code 11-1101(a)(9)). Jurisdiction exists when the petitioner is a legal resident of the District or has actually lived there for at least one year before filing (D.C. Code 16-301(b)).
Washington DC adult adoption at a glance
An adult adoption in the District of Columbia is a Family Court decree that makes one adult the legal parent of another adult for all purposes, including mutual inheritance as if the adoptee had been born to the adopter (D.C. Code 16-312(a)). The adult rule fits in one sentence: a person over eighteen may be adopted with that person's consent once the court is satisfied. The District's real twist sits inside the petitioner's household. A married petitioner's spouse must join the petition, yet a spouse who is the adoptee's natural parent consents instead, and that parent's legal bond with the adoptee survives the decree untouched. The adoptee's legal ties to the other birth parent, including inheritance, are cut off. No agency investigation applies to an adult, and the hearing is held in chambers or a sealed courtroom.
A Capitol Hill stepfather, a mother who consents, and a surname nobody wants changed
Elena has been married to Marcus for nineteen years, and her daughter Noor, now 30, wants Marcus recorded as her father. Marcus has lived in the District for a decade, which settles jurisdiction. Because Elena is Noor's natural parent, she does not join the petition; she signs a consent under D.C. Code 16-302. Noor signs her own acknowledged consent. Noor's husband signs nothing, since the chapter asks nothing of an adoptee's spouse. Noor wants to keep her surname, and that matters here: under 16-312(c) her family name becomes Marcus's unless the decree provides otherwise, so the petition asks for no change. The petition lists her biological father's last known address, and they ask the clerk about serving him. After the decree, Noor's bond with Elena is unaltered, while her inheritance ties to her biological father end.
Relevant Laws
D.C. Code 16-304 (consent; the adult rule in subsection (f))
Subsection (a) requires a written, acknowledged statement of consent filed with the petition. Subsection (b) sets the consent list for a person under eighteen. Subsection (f) allows a person over eighteen to be adopted with that person's consent if the court is satisfied the adoption should be granted.
D.C. Code 16-302 (who may petition and spousal joinder)
Any person may petition. The court may not consider a petition unless the petitioner's spouse joins it, except that a spouse who is the adoptee's natural parent need only consent. A change in marital status before the final decree requires an amended petition.
D.C. Code 16-308 (no investigation when the adoptee is an adult)
Directs the court to dispense with the investigation, report and interlocutory decree when the prospective adoptee is an adult. Subsection (d) states that nothing in the section waives the criminal records check provisions of D.C. Code 4-1305.01 through 4-1305.09.
D.C. Code 16-312 (legal effects, inheritance and name)
Establishes the parent and child relationship for all purposes with mutual inheritance, cuts off the natural family's rights except where a natural parent is the adopter's spouse, and changes the adoptee's family name to the adopter's unless the decree otherwise provides.
D.C. Code 16-301 (jurisdiction of the Superior Court)
Gives the Superior Court jurisdiction over adoption of any adult or child, conferred when the petitioner is a legal resident of the District, has actually resided there at least one year before filing, or another listed ground applies. D.C. Code 11-1101(a)(9) assigns adoption to the Family Court.
Regional Variances
Washington DC adult adoption rules at a glance
Who may be adopted
A person over eighteen, with that person's consent, if the court is satisfied the adoption should be granted (D.C. Code 16-304(f)). Section 16-303 adds that a person, whether a minor or an adult, may be adopted. No category list and no disability condition.
Age of majority and age gap
The age of majority in the District is 18 (D.C. Code 46-101). The adoption chapter sets no minimum number of years between adopter and adoptee and no requirement that the adoptee be younger. Any person may petition (16-302).
Consent of the person being adopted
Required as a written statement, signed and acknowledged before an officer authorized to take acknowledgments, and filed with the petition (D.C. Code 16-304(a), (f)). Revocation is allowed only if a judge finds the consent was not voluntarily given (Adoption Rule 6(a)).
Petitioner's spouse
Must join the petition as a co-petitioner, or the court may not consider it (D.C. Code 16-302). A spouse who is the adoptee's natural parent need not join and only gives consent. A change in marital status before the final decree requires an amended petition.
Adoptee's spouse
Nothing required. The adoption chapter and the Superior Court Adoption Rules contain no consent, joinder or notice requirement for the spouse of the person being adopted.
Birth parents
No consent for a person over eighteen; the parental list in D.C. Code 16-304(b) covers a person under eighteen. The petition states their names and addresses if known (16-305(1)). Whether they must be served under Adoption Rules 4 and 12 is a question for the clerk.
Court
Family Court of the Superior Court of the District of Columbia (D.C. Code 16-301(a), 11-1101(a)(9)). Adoption filings are processed by the Domestic Relations Branch through the Family Court Central Intake Center at the Moultrie Courthouse.
Residency and jurisdiction
Jurisdiction exists when the petitioner is a legal resident of the District or has actually resided there for at least one year before filing (D.C. Code 16-301(b)(1), (2)). Two further grounds are worded around a child to be adopted.
Filing fee
General Family Rule C lists $80 for filing a complaint or petition in the Family Court, and its comment notes that fees for all complaints and petitions are standardized. Confirm the amount with the clerk. A fee waiver may be requested under D.C. Code 15-712.
Investigation
Dispensed with for an adult: the court shall dispense with the investigation, report and interlocutory decree (D.C. Code 16-308(a)(1)). Subsection (d) keeps the criminal records check provisions of 4-1305.01 through 4-1305.09 in force, and their reach to an adult case is worth confirming.
Waiting period
None for an adult. The six month living together requirement does not apply to an adoptee 18 or older (D.C. Code 16-309(c)(2)), and the interlocutory decree period is dispensed with for an adult (16-308(a)).
Hearing and notice
Proceedings are confidential and held in chambers or a sealed courtroom (D.C. Code 16-309(f)). Notice goes by summons, registered letter or as the court orders to each person whose consent is necessary, and a person who formally consents waives notice (16-306).
Name change
Automatic unless the decree says otherwise: the adoptee's family name becomes the adopter's, and the given name may be fixed or changed at the same time (D.C. Code 16-312(c)). The petition states any change desired (16-305(7)).
Inheritance
Mutual inheritance as if born to the adopter, with the natural family's rights cut off except where a natural parent is the adopter's spouse (D.C. Code 16-312(a)). A reference to a child in a will or deed includes an adopted person unless plainly stated otherwise (16-313).
Forms
No adult specific court form. The court's Petition for Adoption is captioned for a minor child, and Adoption Rule 3(a)(2) accepts a form substantially similar in format and content. File one petition per adoptee with an Adoption Information Form and a Vital Records Form.
Time limit to attack a decree
A challenge to a final decree for a jurisdictional or procedural defect must be filed within one year after the final decree became effective (D.C. Code 16-310).
Suggested Compliance Checklist
Confirm the petitioner's District residency
Before drafting days after startingEstablish that the petitioner is a legal resident of the District or has actually lived there for at least one year before filing (D.C. Code 16-301(b)). Those two grounds do not depend on the adoptee, and the court cannot act without one of them or another listed ground.
Settle the spouse's role: joinder or consent
Before drafting days after startingA married petitioner's spouse must join the petition, unless that spouse is the adoptee's natural parent, who gives consent instead (D.C. Code 16-302). Getting this wrong means the court may not consider the petition at all.
Draft the adoptee's acknowledged consent
With the petition days after startingPrepare the adoptee's written statement of consent, signed and acknowledged before an officer authorized to take acknowledgments, and file it with the petition (D.C. Code 16-304(a), (f)). Attorney review of the consent is available through DocDraft.
Draft the sworn petition, including the name decision
Before filing days after startingInclude every item D.C. Code 16-305 lists, including the natural parents' names and addresses if known and any change of name. Decide the surname deliberately, because the family name changes to the adopter's unless the decree provides otherwise (16-312(c)).
Ask about the criminal records check and service
Before filing days after startingAsk the clerk whether the fingerprint based check preserved by D.C. Code 16-308(d) applies to your adult case, since its timing rule runs before the petition is filed, and whether the birth parents must be served under Adoption Rules 4 and 12.
File in Family Court with the required documents
When the consents are signed days after startingFile one sworn petition per adoptee, an extra copy, an Adoption Information Form and a Vital Records Form (Adoption Rule 3(a)) through the Family Court Central Intake Center. The fee rule lists $80 for a petition; confirm it with the clerk.
Move to dispense with the investigation
At or after filing days after startingBecause the adoptee is an adult, the court shall dispense with the investigation, report and interlocutory decree (D.C. Code 16-308(a)(1)). Adoption Rule 8(d) lets the court decide a motion to dispense without waiting the 14 day opposition period.
Review wills and deeds after the decree
After the final decree days after startingThe decree creates mutual inheritance and cuts off ties with the natural family except a natural parent married to the adopter (D.C. Code 16-312(a)). Check existing wills and deeds, since a reference to a child includes an adopted person unless plainly stated otherwise (16-313).
