Every nation in the world has divorce laws except the Philippines (though Muslims have the right to divorce) and the Vatican City. In these two countries, laws only allow annulment of marriages.
Annulment is a legal procedure for declaring a marriage null and void. That is:- that because of an impediment no marriage ever took place. (examples: the priest was a fake, or one of the parties was already married, or was under age, or was forced to marry).
What you have in the Philippines, in almost every case, is divorce but by another name.
