:confused: what's the diff.btwn annullment and divorce?

An annullment is a court order ( unless you are talking about one from the Catholic Church which is only a religious issue)
In a court annullment the marriage is assumed to never have happened, normally they are done if the marriage was not legal to start with, if the marriage was never completed ( sex) and/or they have only been together a short time, ( weeks normally)

If there is any property, any children and the such a divorce has to happen.

A lot may depend on state law, but the normal method of ending a marriage is a divorce. In it, it is acknowledged there was a marriage but it is now ending.
