Under Section 37(2) of the Special Marriage Act, 1954, district court may act where there is:

Section 37(2) allows the district court to "vary, modify or rescind" an order under section 37(1), at the instance of either party, if it is satisfied that "there is a change in the circumstances of either party". A change in the wife's circumstances counts as much as the husband's, and no fixed waiting period applies.
