Summa Theologica

We must now consider compulsory and conditional consent. Under this head there are six points of inquiry:

(1) Whether compulsory consent is possible?

(2) Whether a constant man can be compelled by fear?

(3) Whether compulsory consent invalidates marriage?

(4) Whether compulsory consent makes a marriage as regards the party using compulsion?

(5) Whether conditional consent makes a marriage?

(6) Whether one can be compelled by one's father to marry?
