My spouse was never divorced.

I have found out that my spouse was never divorced from his first marriage in Las Vegas when he was 23 – Where do I stand?

It is most likely that your marriage is void. A void marriage is one which was never legally valid in the first place. It would be void because your partner was already married to another person, when marrying you. To declare your marriage null and void, an application for an annulment must be completed and filed with the court with supporting documents.
