An annulment declares that the marriage in question did not in fact take place, removing it from any legal records filed. In the event that a California couple decides to file for an annulment, their reasoning must fall in line with California law. Here are the grounds for annulment within the state of California: Incest- If the marriage occurred between ancestors, the relationship can be considered illegitimate; Bigamy- If either spouse is still legally married to another individual, the marriage can qualify for annulment; Marriage was not Lawfully Contracted- If the couple did not lawfully follow the requirements for obtaining a marriage license, the marriage could be considered nullified; Minority of a party- If either party is under the lawful age to be married within the state, there are legal grounds for nullification; Unsound Mind- If either party was not of sound mind to enter into the relationship; Force- If either party entered the marriage under duress or force; Fraud- The either party's consent to marriage was done so under fraudulent circumstances.
