You may have heard of someone seeking an annulment shortly after getting married. But how is this different from getting a divorce? A dissolution of marriage and an annulment are two very different legal actions. A divorce recognizes that there was a legal marriage and now one or both parties are seeking to dissolve that marriage. However, at the root of an annulment is claiming the marriage was never legally recognized. Therefore, it did not exist. You may have heard of the term "null and void." In other words, the marriage is void.
