State exceptions, reporting duties, and assessment tools for clinicians treating survivors

A 16-year-old in Mississippi can still marry with a parent's signature and a court sign-off; a 16-year-old in California will be barred from marriage entirely after January 1, 2027. That divide is not academic. California's ban makes it the 18th state to prohibit child marriage; the practice remains legal in 32 states.
For MFTs, the clinical stakes surface later. An adult client's trauma, power imbalance, or coercive control may trace back to an adolescent marriage the law treated as legitimate and left no divorce mechanism. Clinicians trained only on adult relational patterns can miss that developmental rupture.
California's new law sets a simple rule: no one under 18 may marry or enter a domestic partnership in the state.1 Governor Gavin Newsom signed AB 1267 on September 30, 2026, and the change takes effect January 1, 2027.1 The governor's office announced the signing alongside survivor advocates, including Courtney Stodden.1
Before this law, California had no minimum marriage age. A child could marry if a parent consented and a judge approved.1 The state also provided no divorce mechanism for people under 18, which left some minors legally trapped in marriages they could not end.2
You may see both "32 states still allow child marriage" and "17 states ban it with no exceptions." Both figures describe the same landscape at different moments or under different definitions. Before California's law, 17 states had absolute 18-and-up bans. Once California's law is effective, that number becomes 18, leaving 32 states that still permit marriage involving someone under 18 under some conditions, such as parental consent, judicial approval, or no specified minimum age.3 Reports dated before September 2026 may list 33 states allowing under-18 marriage because California was still among them.4
The law is not retroactive. Adults married as minors cannot use it to undo those marriages, and it creates no new protections in the other 32 states.2 For MFTs, that means your next adult client may still carry the relational aftereffects of a legal adolescent marriage, and those histories belong in your LMFT private practice legal and ethical considerations no matter where they live now.
State child marriage laws cluster around exception types: parental consent, judicial approval, pregnancy, clerk-issued licenses or age-gap limits, and no statutory minimum. In this snapshot, Mississippi, New Mexico and Oklahoma report no statutory minimum marriage age. The table below shows representative states and the lowest permitted age; it is not a complete 50-state list, and statutes change often, so verify against current state code or a legislative tracker.
| State | Minimum Age (Lowest Permitted) | Exception Type / Conditions | Statute Citation |
|---|---|---|---|
| Arkansas | 17 years | Pregnancy may lower the minimum marriage age; parental consent and judicial approval rules also apply. | N/A |
| California | 18 years | No exceptions; a 2026 law repealed the prior parental-consent and judicial-approval provisions. | 2026 California child marriage ban law; exact code section not identified |
| Connecticut | 18 years | No exceptions. | N/A |
| Delaware | 18 years | No exceptions. | N/A |
| Georgia | 18 years | Exception only for court-emancipated minors. | N/A |
| Indiana | 18 years | Exception only for court-emancipated minors. | N/A |
| Kansas | 15 years | Age floor is 15; exceptions include parental consent and judicial approval, subject to statutory conditions. | N/A |
| Michigan | 18 years | No exceptions. | N/A |
| Mississippi | No statutory minimum | Judicial approval is required for all males under 17 and females under 15; the state permits marriage below age 16 without a judge in some circumstances. | N/A |
| New Mexico | No statutory minimum | Pregnancy may lower the minimum marriage age; the state has no statutory age floor. | N/A |
| New York | 18 years | No exceptions. | N/A |
| Oklahoma | No statutory minimum | Pregnancy may lower the minimum marriage age; the state has no statutory age floor. | N/A |
| Virginia | 18 years | Limited exception for court-emancipated minors. | N/A |
As of 2026, 18 states set a flat minimum marriage age of 18: no parental consent, court approval, or emancipation can authorize a marriage below that age.1 The 18-only states are California, Connecticut, Delaware, Maine, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Oklahoma, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia, and Washington.2
California's law was signed in 2026 and becomes operative January 1, 2027, so the state is counted as the 18th even before the ban takes effect.1 For the other states on this list, underage marriage is not licensed under state law.
A flat 18 minimum does not end every underage marriage pathway. Emancipated minors may still marry in states with lower thresholds4, tribal and territorial legal systems remain jurisdiction-dependent, and recognition of out-of-state marriages involving a minor is not clearly addressed in ban statutes.2 A marriage performed where parental consent or court approval is still allowed may appear in a clinician's office no matter where the client lives now.
A client's current state of residence tells you little about where, or at what age, they married. Ask directly about age at first marriage and the legal context in which it occurred, not just current location.
Brittany Bee told the BBC she married at 17 to escape an abusive home and described it as going "from one prison to another." Sara Tasneem said she was forced to marry a man nearly twice her age at 15, became a mother at 16, and left school. Courtney Stodden married actor Doug Hutchison in 2011 when she was 16 and he was 50. Unchained At Last estimates nearly 315,000 children were legally married in the U.S. from 2000 through 2021, including children as young as 10; 86% were girls and 96% were 16 or 17. Earlier peer-reviewed work counted roughly 297,000 from 2000 through 2018, but the newer Unchained At Last estimate covers a longer period.
The adult client may bring trauma symptoms, histories of coercive control, early parenthood, interrupted education, and a marriage that began as an escape from an abusive home. National research does not yet offer one fixed prevalence for mental health or economic outcomes, but public health assessments recognize social isolation, domestic violence, schooling interruption, and reduced career or vocational opportunity as risks associated with early marriage, which is why domestic violence screening in family therapy matters.1
Before the new law, California minors had no legal mechanism to get divorced, and similar barriers persist in many states.2 A client who says she "couldn't leave" may be describing a legal reality, not just a relational one. Asking about age at first marriage, including whether divorce was accessible, can help clinicians use MFT risk assessment family dynamics to distinguish past coercive control from current safety needs.
A therapist's confidentiality promise stops where state child-abuse reporting law begins, and that boundary can surprise clinicians who assume a legal marriage neutralizes it. The revised AAMFT Code of Ethics, effective January 1, 2026, requires MFTs to disclose confidentiality limits at intake and to release information only with written authorization or when the law mandates or permits it. That includes reports of child abuse: mandated reporting preempts confidentiality, and a prior disclosure at intake does not eliminate the duty.
Whether a married minor may consent to their own therapy is state-dependent. When a client is legally incapable of consent, the AAMFT Code directs therapists to seek a legally authorized person's consent where state law permits , a decision that belongs within MFT Scope of Competence. Conjoint work with an adult spouse of a minor raises additional safety, Therapist Safety, and ethical concerns that deserve careful weighing, not procedural reflex.
Document the ages, the disclosed facts, the statute you considered, and your consultation. Consult a colleague, an attorney, or your licensing board when the threshold is unclear. This section is educational, not legal advice.
Use screening instruments as one part of a broader clinical inquiry, not as a stand-alone guarantee of safety. At intake, ask separately about age at first marriage, age gap, consent history, and who held legal control; these intake questions are not validated instruments. Screen each partner individually before any conjoint session, know when conjoint work is contraindicated, and if the client is still in the marriage, prioritize safety planning before any couple focused intervention.
| Tool | What It Screens | Validation Status | Best Use in Session |
|---|---|---|---|
| Danger Assessment (DA) | Likelihood of lethality or near lethality in an intimate partner violence case, including risk of femicide or attempted femicide. | Psychometrically validated. Acceptable internal consistency (.70 to .80), test-retest reliability .89 to .94, and convergent construct validity supported. | Use privately with a woman experiencing intimate partner violence to determine danger of being killed by an intimate partner. The 20-item instrument uses weighted yes/no risk factor scoring and a calendar documenting severity and frequency during the past year. |
| Spousal Assault Risk Assessment (SARA) | Risk of intimate partner re-assault, severe re-assault, or homicide. | Identified in a review as one of four stand-alone IPV risk-assessment instruments with the highest average predictive validity or greatest accuracy for predicting re-assault, severe re-assault, or homicide. | Use as a stand-alone IPV risk-assessment instrument in appropriate professional and practice settings. The source describes it as an assessment instrument rather than a general screening measure. |
| Ontario Domestic Assault Risk Assessment (ODARA) | Risk of intimate partner re-assault, severe re-assault, or homicide. | Identified in a review as one of four stand-alone IPV risk-assessment instruments with the highest average predictive validity or greatest accuracy for predicting re-assault, severe re-assault, or homicide. | Use as a stand-alone IPV risk-assessment instrument in appropriate professional and practice settings. The source describes it as an assessment instrument rather than a general screening measure. |
| Domestic Violence Screening Inventory (DVSI) | Risk associated with intimate partner violence, including risk of re-assault, severe re-assault, or homicide. | Identified in a review as one of four stand-alone IPV risk-assessment instruments with the highest average predictive validity or greatest accuracy for predicting re-assault, severe re-assault, or homicide. | Use as a stand-alone IPV risk-assessment instrument in appropriate professional and practice settings. The source describes it as an assessment instrument rather than a general screening measure. |
| Individual IPV screening before conjoint couples therapy | All couples should be assessed for intimate partner violence, including violence history, frequency, context, injury, lethality, fear, and coercive control. Screening should include written and verbal assessments. | The guidance supports comprehensive IPV assessment but does not identify one specific screening instrument or provide a validation estimate for the overall screening procedure. | Assess each partner individually before conjoint work. Do not provide conjoint couples therapy when there is severe control over the other partner or coercion. If the partner feels safe discussing violence, assess frequency, context, and injury or lethality before deciding whether conjoint treatment is appropriate. |
An estimated 9,000 California girls were married each year before the state's ban, according to Unchained At Last. For MFTs, that figure underscores why survivor autonomy, not rescue, should anchor treatment.
When a client says she "chose" marriage at 16 or 17, name the surrounding pressure directly: an escape from an abusive home, family insistence, or a legal system that offered no divorce mechanism. You can say, "That may have been the most survival-oriented choice available to you." Then let the client decide what that marriage meant. Avoid rescue narratives that reframe her as a passive victim or push disclosure on your timeline.
Family-of-origin work requires nuance across modern family structures. Do not pathologize a client's cultural or religious community. Instead, screen for ongoing pressure and family enmeshment: does family still control finances, housing, or contact with children? Ask what support she wants from those relationships now, not what you think she should want.
Trauma-informed practice is incomplete without practical planning. Assess gaps in education, financial independence, parenting support, and safe housing. Help clients build concrete skills, from requesting school records to opening a bank account, while you hold the clinical space.
MFT curricula are slowly moving beyond the assumption that couples enter therapy as two adults with equal power. Yet many training gaps remain, especially for clinicians who will meet clients whose adolescent marriages were legally sanctioned and who may present with power imbalance in age gap relationships. Standard couple assessment texts presume both partners can negotiate, consent, and leave. Mandated reporting modules rarely cover married minors, so trainees may not recognize what they are seeing when an adult client describes being wed at 15 or 16.
Students should ask programs how these topics appear in practicum supervision, not only in lectures. Marriagefamilytherapist.org degree program profiles can help compare curricula across schools, including whether programs offer trauma-focused tracks, a child therapist certification pathway, or legal and ethics content tied to state licensure.
