Annulment, also known as the nullity of a marriage, is the legal procedure that invalidates or cancels a marriage, declaring it legally null and void. It would be as if the marriage never existed or occurred in the first place. After an annulment, the individuals involved can identify themselves as “single” instead of “divorced”.
Both a marriage annulment and divorce seek to end a marriage. The difference between the two is that the former states that the union never existed or was invalid, whereas the latter recognises the union happened but had irretrievably broken down. Parties need to be married for at least 3 years before they can file for divorce whereas such a condition does not exist for an annulment. In fact, depending on which fact you are relying on to annul the marriage, the application must be made within the first 3 years of marriage.
