A process to annul (cancel) a marriage has been available in Connecticut since 1877. An annulment is the dissolution of a marriage based on facts existing at the time of the marriage which render the marriage void or voidable.
The current statute lists several grounds for annulment, including:
marriage not consummated;
marriage of certain kindred (family members);
marriage performed without a valid marriage license; or
marriage performed by someone unauthorized to do so.
The process is much like that of a divorce.
