Is it rude to ask someone if they are married?
If you are interested in that person in a romantic way, then asking about her marital status is a must. All other cases – job interview, a stranger on the street, a business meeting, etc – where it's simply your curiosity, then it's not polite to ask.
What happens if you marry someone who is already married?
Bigamy results in an invalid marriage. If two people enter into a marriage when one of them is still legally married to someone else, the state will invalidate the new marriage. This happens even when the person thought they were legally divorced. Bigamy laws apply to all forms of marriage.
When should you bring up your marriage in a relationship?
According to their research, majority of couples are having the marriage conversation way ahead of the engagement. The survey found that 94% of couples discuss getting engaged in the six months before actually doing so. A full 30% of those talk engagement and marriage at least once a week.
