A Connecticut Annulment Complaint is a legal document that is filed with a court in the state of Connecticut when a person wants to void or cancel a marriage. This type of complaint seeks to have the marriage declared null and void as if it never existed. It is important to note that an annulment is different from a divorce in that a divorce is a legal dissolution of a valid marriage, whereas an annulment voids the marriage so that it is as if it never existed. There are two types of Connecticut Annulment Complaint: a Complaint for Annulment based on a Voidable Marriage, and a Complaint for Annulment based on a Void Marriage. A Complaint for Annulment based on a Voidable Marriage is filed when a marriage was entered into in good faith by both spouses, but can be voided due to certain factors such as fraud, duress, or lack of mental capacity of one of the parties. A Complaint for Annulment based on a Void Marriage can be filed when the marriage is considered void from the start, such as when a party was already married or there is a close family relationship between the parties.
