§ Constitutional Amendment
Marriage Standards & Protection Amendment
Current Status
Existing Law
- No explicit constitutional protection for same-sex marriage (Obergefell v. Hodges established right through Fourteenth Amendment interpretation)
- Federal law permits child marriage through absence of minimum age requirement
- Interstate marriage recognition relies on Full Faith and Credit Clause interpretation
Current Authority
- Marriage licensing authority resides with individual states
- Supreme Court interpretation of Fourteenth Amendment provides current marriage equality framework
- States set minimum marriage ages with varying exception provisions
Existing Limitations
- 43 states allow child marriage through parental consent or judicial bypass exceptions
- Religious liberty boundaries with civil rights remain subject to case-by-case interpretation
- Marriage equality vulnerable to Supreme Court reversal (similar to Roe precedent)
- Patchwork state laws enable interstate conflicts and regulatory evasion
Problem
Specific Harm
- Research across 43 countries shows minimum age laws with exceptions produce statistically indistinguishable outcomes from no minimum age laws
- Only strict 18-year minimums without exceptions measurably reduce child marriage and associated harms
- Exception-based laws enable exploitation through parental consent, judicial bypass, and interstate jurisdiction shopping
Who is Affected
- Minor children, predominantly girls (86% of child marriages)
- Same-sex couples facing legal uncertainty about marriage recognition
- Religious institutions facing unclear boundaries regarding obligations
- Commercial businesses and public accommodations navigating conflicting standards
Gaps in Current Law
- No federal minimum marriage age requirement
- No constitutional codification of marriage equality
- No clear framework balancing religious liberty with civil rights
- No interstate coordination to prevent jurisdiction shopping
Accountability Failures
- Parents can consent to harmful child marriages regardless of circumstances
- Judicial bypass enables rubber-stamping of harmful marriages
- Interstate jurisdiction shopping allows evasion of stronger state protections
- Legal uncertainty creates costly litigation between religious conscience and civil rights
Proposed Reform
Primary Policy Change
- Codify marriage equality as fundamental constitutional right for consenting adults
- Establish strict federal prohibition on marriage licenses for persons under 18 without exceptions
- Create clear framework balancing religious liberty with civil rights protections
New Requirements
- All marriages lawfully licensed in one State shall be recognized as valid in every State for all legal purposes (Full Faith and Credit provision)
- Interstate information systems to verify age compliance and prevent jurisdiction shopping
- Federal technical assistance to States for implementation
- Strict 18-year minimum age for all marriage licenses nationwide
New Prohibitions
- No marriage license shall be issued to any person under the age of eighteen years
- This prohibition shall apply without exception, including parental consent or judicial authorization
- Religious liberty protections shall not apply to commercial public accommodations, for-profit businesses, government contractors providing secular services, or denial of essential services
- Religious institutions cannot discriminate in public accommodations, deny emergency services, or violate employment law for non-religious positions
Enforcement
- Congress shall have power to enforce by appropriate legislation
- Interstate information systems for marriage verification
- Federal technical assistance to States
- Civil remedies for violations
- Religious institutions protected from compulsion to solemnize, host, or recognize marriages contrary to religious beliefs
- Tax-exempt status, accreditation, and licensing shall not be revoked based solely on religious beliefs regarding marriage
- All marriages valid under State law prior to ratification shall remain valid (prospective application)
- No criminal or civil liability for marriages lawful when contracted

Confidence: MEDIUM
Estimation Basis: The CBO found a slightly positive impact on the budget if same-sex marriages were to be legalized in all states and recognized by the federal government: an extra $1 billion each year for the next ten years. Child marriage cost estimates derived from Stout estimated that the quantifiable annual cost of child marriages is at least $37.6 million, including $5.2 million in mental health costs and $32.4 million in public assistance costs. Marriage equality economic contributions based on BCG research suggests that marriage equality for same-sex couples has contributed up to $125 billion to the US economy since 2004. Child marriage earnings impact based on women who marry as children have, on average across 15 countries, earnings that are nine percent lower than if they had married later.
Key Research Findings:
- Nearly 300,000 minors, under age 18, were legally married in the U.S. between 2000 and 2018.
- Today, the United States is home to an estimated 823,000 married same-sex couples. Over 591,000 same-sex couples have married since the U.S. Supreme Court's decision in Obergefell v. Hodges.
- VAWA: $732 million for programs included in VAWA provides baseline for state incentive grants.
- Every year that a girl marries early (i.e., before 18) is associated with a reduction in the likelihood of completing secondary school of typically four to 10 percentage points, depending on the country or region.
- "The Congressional Budget Office (CBO) estimates that on net, those impacts would improve the budget's bottom line to a small extent."
