Presumption of a valid marriage is a rebuttable one, it is for the other party to establish the same.
evidence Act S. 114
Section 114 refers to common course of natural events, human conduct and private business. The Court may presume the existence of any fact which it thinks likely to have occurred. Court while reading the provisions of Sections 50 and 114 of the Evidence Act held that, the act of marriage can be presumed for the common course of natural events and conduct of the parties as they are borne out by the facts of a particular case and therefore, it is the husband to discharge his burden to prove that, no marriage has taken place.
