When you get an annulment, the court declares that you were never legally married. It is not the same as a divorce, which ends a valid marriage. In an annulment, it is as if the marriage never happened. An annulment is not easier or faster to get than a divorce. In Massachusetts, there are very few reasons that you can get an annulment, and the court requires clear proof of the reason why you want the annulment.
The law governing annulment is G. L. c. 207, § 14 .
