What are the requirements for the annulment of a marriage?
Being under the canonical age, impotence, consanguinity, lack of intention to be faithful, lack of intention to have children (sterility is not a ground), psycho-sexual incompatibility (e.g. abnormal sexual demands or one person being homosexual), psychological abnormality, lack of consensus ad idem (e.g. a very different understanding of marriage), deception (e.g. marrying simply to obtain an inheritance upon the death of a spouse), Pauline privilege (when 2 non-Christians marry and one subsequently becomes a Christian, resulting in the breakup of the marriage).
