When a marriage is annulled, it is determined that the marriage was never legally valid. The grounds for annulment vary, but most are based on the premise that some facts or events invalidate the legality of the marriage; these can include bigamy, insanity, intoxication, or fraud, among others. Unlike a divorce, which is the legal dissolution of the marital contract, an annulment makes it as if the marriage never happened, reverting property and assets back to their status from before the marriage. Marriage annulment attorneys have experience in determining which marriages can be annuled and how annulments affect the division of property, assets, and child custody. Because of the unique nature of annulments, family law attorneys who have experience with annullments can best navigate the different laws and complications arising from these cases.
