What is an annulment?
In plain terms: an annulment is a court’s way of saying a marriage was never valid — legally, as if it never happened. A divorce, by contrast, ends a marriage that was valid. Same exit, very different door.

“As if it never happened.”
When a court grants an annulment, it issues a decree declaring the marriage void. In the eyes of the law, you were never legally married.
That can matter for how you think about the chapter — and sometimes for practical things like names, paperwork, and how you move forward. It does not mean the law ignores what happened: a court can still sort out property, debts, and any children’s issues fairly.
- Annulment — the marriage was never valid
- Divorce — a valid marriage is ended
- Both are handled in Nevada’s Family Court
Void vs. voidable.
Nevada law sorts annulment into two categories. The difference sounds technical, but it’s actually simple.
Never legal to begin with
A void marriage was invalid from the very start — the law never recognized it. Two situations make a Nevada marriage void automatically:
- Bigamy — one person was already married to someone else.
- Close relatives — the couple is related closer than second cousins, including by half-blood.
Because the marriage was never valid, void grounds can generally be raised at any time.
Valid until a court undoes it
A voidable marriage is treated as valid until someone asks a court to annul it and proves a ground. These are the more common Las Vegas situations:
- Want of understanding (gross intoxication, mental incapacity)
- Fraud about something central to the marriage
- A minor married without required parental consent
- Grounds that would void a contract in equity, such as duress
Voidable grounds are best acted on promptly — more on timing in Grounds.
What this looks like in real life
Picture a couple who met on a Friday night on the Strip, married at a chapel a few hours later, and woke up Sunday realizing neither of them was thinking clearly — or even truly remembers saying “I do.” That’s a textbook want of understanding situation: a voidable marriage that a court may annul.
Now picture someone who discovers, weeks in, that their new spouse is already married to someone else. That’s bigamy — a void marriage that was never legal at all.
Different facts, different category, but the same reassuring truth: Nevada law has a calm, established way to set the record straight.
