What happens when you find out that your husband lied on our marriage application about how many times he was married perviously?

If I say without knowing more about the nature of your question. There are a possible number of issues that could arise from this issue. First, obviously, if he remains married to any of those individuals it would be bigamy, which is a felony. 

Additionally, it could raise issues to the validity of the marriage if it was a significant statement. Not that it would invalidate the marriage, but could raise issues for a potential annulment. An annulment is granted when the underlying marital contract is void for a contractual reason such as the inability to contract, fraud or legality. If your marriage was premised on your belief about his history and you find that he lied, you may be able to support grounds for annulment.

You should speak with an experienced attorney who is familiar with these areas of law.

Good luck.
