And it’s closest sibling, annulment.

Do you believe that invalid or "null" marriages occur?

For example, is a drunken Vegas marriage valid?

Marriage to a close relative?

The principle is valid.

The question regards particulars. What constitutes a valid marriage?

What is marriage?

Please. We're talking about much, MUCH less than these extreme examples. Couples, MARRIED for years - DECADES - , with children, and a life, home, possessions purchases together.

The number of sought annulments of long-standing, fruitful marriages denied are VERY minuscule. You cannot deny this.
