The length of the marriage has nothing to do with the question of the availability of an annulment. The Court may grant an annulment if the marriage is void or voidable under very specific statutory requirements. One classic example is the regrettable Las Vegas marriage. If one spouse was incapable of effective consent because that spouse was drunk, an annulment may be possible. Another basis for annulment is impotence of a partner that was not known before marriage.
