(1) That the party in whose behalf it is sought to have the marriage annulled was eighteen years of age or over but below twenty one, and the marriage was solemnized without the consent of the parents, guardian or person having substitute parental authority over the party, in that order, unless after attaining the age of twenty one, such party freely cohabited with the other and both lived together as husband and wife;

(2) That either party was of unsound mind, unless such party, after coming to reason, freely cohabited with the other as husband and wife;

(3) That the consent of either party was obtained by fraud, unless such party afterwards, with full knowledge of the facts constituting the fraud, freely cohabited with the other as husband and wife;

(4) That the consent of either party was obtained by force, intimidation or undue influence, unless the same having disappeared or ceased, such party thereafter freely cohabited with the other as husband and wife;
