Montana Allows Proxy Marriages
Some Cousins Can Marry Only If They Are Older Or Infertile

America’s cousin-marriage laws are a confusing patchwork. Some states allow first cousins to marry. Some ban it. Others create exceptions that sound oddly specific.
In Arizona, first cousins generally cannot marry unless both are 65 or older, or unless a court accepts proof that one cousin is unable to reproduce. Utah has a similar age-based exception, allowing first cousins to marry if both are 65 or older, or if both are at least 55 and one is unable to reproduce.
Child Marriage Loopholes Still Exist
This one is less funny and far more disturbing. Despite years of reform, underage marriage is still legal in many U.S. states under certain exceptions. In some places, minors can marry with parental consent, court approval, or other special conditions.
That means a person can be too young to vote, buy alcohol, or sign many contracts, yet still be allowed to enter a marriage. Critics argue this creates a dangerous situation, especially when a minor is marrying an adult. Supporters of reform say these loopholes can trap young people in relationships they are not legally or emotionally equipped to escape.
Covenant Marriage Makes Divorce Harder

In Arizona, Arkansas, and Louisiana, couples can choose a special legal category called covenant marriage. It is not the standard marriage most people enter. It is a stricter version that requires premarital counseling and makes divorce harder later.
At first, this may sound like a romantic promise. The couple is declaring that marriage is serious and should not be treated casually. But legally, it also means they accept limited grounds for divorce. If the relationship breaks down, leaving can involve more restrictions than in a regular marriage.
Common-Law Marriage Can Surprise Couples
In some states, marriage does not always require a big ceremony, a white dress, or a dramatic kiss in front of guests. Common-law marriage can still be recognized when a couple meets specific legal requirements, which often include living together, presenting themselves as married, and intending to be married.
This does not mean every long-term couple automatically becomes married. That is a common misunderstanding. But in states that still recognize common-law marriage, relationship behavior can carry legal weight. A couple may think they are simply living together until a dispute, breakup, inheritance issue, or benefits claim forces the question into court.
Some States Make Couples Wait After Getting A License
A marriage license sounds like permission to get married. In some states, however, getting the license does not mean the couple can immediately use it. Waiting periods still exist.
New York generally requires couples to wait 24 hours after receiving a marriage license before holding the ceremony. Texas has a 72-hour waiting period in many cases. Wisconsin has a waiting period too, and its license rules also include a time window for when the marriage must happen.
Your Friend May Not Be Allowed To Officiate

Modern weddings often feature a close friend or relative performing the ceremony. It feels personal, sweet, and very modern. But in some places, the law still cares deeply about who is allowed to make a marriage official.
New York City requires marriage officiants to register with the City Clerk before performing ceremonies within the five boroughs. Virginia can also be strict about authorization, and people who perform marriages without legal authority can face penalties. That means a heartfelt ceremony may not be enough if the person leading it has not followed the rules.
Conclusion
America’s marriage laws prove that love may be simple, but legal marriage is anything but. One state may let a couple marry by proxy. Another may make them wait days after getting a license. Another may allow a stricter covenant marriage, while another may still recognize a relationship as common-law marriage without the couple holding a traditional ceremony.
Some of these laws are merely odd. Others are deeply serious and deserve reform. The biggest lesson is that marriage is not just a romantic decision. It is a legal status shaped by state rules, local clerks, court procedures, and sometimes old ideas that refuse to disappear.
Before any couple assumes the law is straightforward, they should check the rules in the state where they plan to marry. The ring may sparkle, the vows may sound beautiful, and the photos may look perfect, but behind every wedding is a legal system that can still be surprisingly strange.
