Sir,
Divorce by mutual consent is addressed under S. 13 B of the Hindu Marriage Act, 1955 and Section 28 of the Special Marriage Act, 1954. For parties to seek divorce by mutual consent, they must be living separately for a period of atleast one year, and must resolve towards the end of the marriage. They must not be performing marital obligations – physical separation is not a criteria. The marriage must be beyond reconciliation, and presenting a petition for divorce together does not indicate amicability. Consent, however, must be free. If after 6 months the petition is not withdrawn, the parties may move the court within 18 months, after which the Court may grant the divorce.
I hope this clarifies your doubt.
