Can You Marry Your Cousin Uk
So, you’ve been swapping Christmas presents with your cousin for years, and now you’re wondering if you can swap vows. Maybe a family wedding just got a little too cozy, or you’ve been rewatching Game of Thrones and think Targaryen logic applies to your life. Let’s get this straight: can you marry your cousin in the UK?
The short, shocking answer is: yes, but only if you’re not too closely related. In England, Wales, and Northern Ireland, marrying a first cousin is perfectly legal. Scotland? Same deal—go for it, just make sure you’ve got a good excuse for the awkward family reunions.
But here’s where it gets weird. You cannot marry your sibling, parent, child, grandparent, aunt, uncle, niece, or nephew. That’s called “prohibited degrees,” and it’s basically the law’s way of saying, “No, you can’t make a family tree that’s just a circle.”

The Great Cousin Loophole
First cousins are in a bizarre legal sweet spot. They’re not in the “close family” ban list, so go ahead and rent that church. But double first cousins—where both sets of parents are siblings—are still just cousins. The law shrugs and says, “Sure, roll the dice on genetics.”
Why is this allowed? Historians say it’s because your average first cousin shares only about 12.5% of your DNA. That’s not zero, but it’s not “let’s invent a royal dynasty” territory either. Plus, back in the day, marrying your cousin kept the farm in the family—literally.
The “But My Genes!” Panic
You’re probably imagining children with three arms and a sudden love for banjos. Relax. The risk of birth defects for first-cousin couples is only about 1.7% higher than unrelated couples. That’s the same bump you get if the mother is over 40 or the father has a questionable beard.
Still, your GP might raise an eyebrow if you announce your engagement to Cousin Becky. They’ll likely suggest genetic counseling, not an exorcism. And if you’re both healthy, the chances of a “Royal Targaryen” baby are laughably low.
The Creepy Exception: Step-Relatives
Believe it or not, you can marry your step-sibling if you’re both over 21 and never lived together as children. That’s legal. But marry your blood cousin? Totally fine. The law has some wild priorities, right?
What about adopted siblings? You can marry them too, as long as you weren’t raised as a sibling during your childhood. So if you and your adopted cousin met at age 25, the law gives you a thumbs-up. Cue the awkward family dinners where everyone pretends you’re just “really good friends.”
The “But What About the Royals?” Factor
Historically, British royalty married cousins like it was a competitive sport. Queen Victoria married her first cousin Albert, and most of her children married cousins. The result? A gene pool that occasionally produced tragic hemophilia, but also a lot of very confused family photo albums.
Today, the law applies to everyone—including the monarchy. So no, Prince William cannot marry his cousin. Well, he can, but he’d have to give up the throne? But we’re talking about you, not a future king. You’re fine.
The Global Cousin-Shaming
Here’s a fun fact: over 10% of marriages worldwide are between first or second cousins. In many Middle Eastern, South Asian, and African cultures, it’s standard practice. The UK is actually weird for making a big deal out of it—but only until you remember that the US has 25 states where it’s a crime. Texas, Nevada, and Florida say, “Nope, not today, Cousin Bob.”
So if you’re a UK resident planning a road-trip wedding to Vegas, check the map. You might end up arrested in Arkansas for doing something that’s perfectly legal back home. That’s a honeymoon story nobody wants.
The Final Verdict
Can you marry your cousin in the UK? Absolutely, yes. But let’s be honest: the real question is, should you? If you’re both consenting adults, not under duress, and you’ve already explained it to your grandmother (who will never stop bringing it up at Christmas), then go for it.
Just remember: no one will ever believe your love story isn’t a plot from a medieval fantasy series. And if anyone asks about your kids, just say they have “old-fashioned genes.” Then change the subject to something less weird, like the British weather.
