The Plural Marriage Project
A United States legal reform project

Plural marriage is not banned because
it is wrong. It is banned because
the paperwork is hard.

No major religion's original scripture forbids it. The U.S. Constitution does not require monogamy by name. The real barrier is administrative: tax forms, inheritance lines, and insurance policies built for exactly one spouse. That barrier is solvable.

The thesis of this project: Every objection to legalizing plural marriage in the United States is administrative, not moral. And every administrative problem already has a working solution somewhere else in American law.

How the case is built

Three pillars, in order

We lead with the law, because law is what actually has to change. We ground it in faith and history, because the practice is ancient and never universally forbidden. And we close every objection, because a framework that cannot be attacked is a framework that can pass.

The Legal Case

What U.S. law actually says today, why the ban is bureaucratic rather than constitutional, and the seven legal instruments that make plural marriage administratively workable.

Faith & History

What the scriptures of every major world religion actually say. The short version: regulated, practiced by major figures, and never forbidden in any original holy text.

Answering Objections

Taxes, inheritance, divorce, insurance, immigration, consent, fairness, and culture. Ten objections, ten fixes, each modeled on a system the United States already runs.

Every objection solved ›

"If the government can write the rules for a three-parent household, a multi-partner business, and a blended estate, it can write the rules for a plural marriage. It simply has not been asked to."

Why now

The legal ground has already shifted

This is not a hypothetical debate anymore. The momentum is real, recent, and American.

Utah decriminalized it in 2020

Utah Senate Bill 102 reduced polygamy between consenting adults from a felony to an infraction, roughly the legal weight of a traffic ticket. A U.S. state has already decided that consenting plural households should not be treated as criminals.

Obergefell reopened the question

When the Supreme Court recognized same-sex marriage in Obergefell v. Hodges (2015), it grounded marriage in liberty and equal dignity for consenting adults. In dissent, Chief Justice Roberts warned the same logic leads directly to plural marriage. We agree with the reasoning, if not the alarm.

Decriminalization is spreading

Somerville, Cambridge, and Arlington, Massachusetts have passed ordinances recognizing multi-partner domestic partnerships. The conversation has moved from "never" to "how."

The model already exists abroad

Roughly 58 countries recognize some form of plural marriage today, running the tax, inheritance, and family-law machinery to support it. The administrative problems this project solves are problems other legal systems have already solved.

Honest by design

We weigh it both ways, and we hold power accountable

A reform worth passing can survive an honest ledger and can answer its hardest critic: the fear that the head of a family will abuse it.

Pros & Cons

The real benefits and the real risks, side by side, with every risk mapped to a control that answers it. No cherry-picking.

Weigh the ledger ›

Accountability

How the head of the family, man or woman, is held totally accountable: a trustee's legal duty, full financial transparency, criminalized coercion, and real penalties.

The barrier is bureaucracy. Here is the fix.

Read the legal framework, then judge it by the hardest objection you can think of. We have probably already answered it.
