The certificate (Decree) from family court is the one and only one legal document valid all over India. So you have to file application for divorce before family court to obtain divorce after expiry of one year from date of your marriage .
If possible try for mutual divorce petition. Divorce by Mutual consent saves time, money and energy for both,
Leaves no room for unnecessary quarrel and most importantly avoid washing your dirty linen in public.
Formalities to be complied with
(a) A petition is to be presented jointly by the parties to the marriage.
(b) The parties have been living separately for a period not less than one year. It is doubtful whether it was intended by the legislators that the parties have lived separately by mutual consent or by force of circumstances or situation.
But it does not seem necessary for the court to go into that matter provided the condition of separate living under the same roof of matrimonial home or in separate residence by the parties is satisfied. Unless the consent of any of the parties to such petition is vitiated by coercion, fraud or undue influence, the court ought not travel beyond the statutory condition of its jurisdiction.
(c) The parties have failed for any reason whatsoever to live together. In other' words, no reconciliation or adjustment is possible between them.
(d) The parties have freely consented to the agreement of dissolution of marriage.
The following are the grounds for divorce in India on which a petition can be filed only by the wife.
1. If the husband has indulged in rape, bestiality and sodomy.
2. If the marriage is solemnized before the Hindu Marriage Act and the husband has again married another woman in spite of the first wife being alive, the first wife can seek for a divorce.
3. A girl is entitled to file for a divorce if she was married before the age of fifteen and renounces the marriage before she attains eighteen years of age.
4. If there is no co-habitation for one year and the husband neglects the judgment of maintenance awarded to the wife by the court, the wife can contest for a divorce.
