Under Section 19 of the Special Marriage Act, 1954, marriage under the Act shall be deemed to effect:

Section 19 provides that the marriage under the Act of a member of an undivided family professing the Hindu, Buddhist, Sikh or Jaina religion "shall be deemed to effect his severance from such family". Severance ends his membership of the joint family; it does not forfeit his share in its property or change his religion to that of his wife. Section 21A disapplies section 19 where both parties profess one of these religions.
