My parents divorced. Are your's?
No they are not.
That's great! I love to hear success stories. They couldn't annull the marriage.
Why couldn't they annull it?
They couldn't delcare it null and void legally with children.
Oh that is interesting.
Yes. There are other ways you can annul by "de jure" separation. That's a legal process formalizinga "de facto" separation but still remaining legally married.
