Divorce might be easy? Well, when it is difference between an annulment and a divorce, an annulment is much harder to get. There are two categories of marriages for which an annulment may be sought in Pennsylvania. The first are marriages that are void by their existence. The second are marriages that are voidable upon action be either party.
A marriage that is void is never considered to have been valid. In other words, a legal marriage never existed. Marriages are considered to be void in the following instances: the parties are closely related; either party was unable to consent because of mental illness or incapacity; or "either party at the time of such marriage had an existing spouse and the former marriage had not been annulled nor had there been a divorce, except where that party had obtained a decree of presumed death of the former spouse." 23 Pa.C.S.A. § 3304.
