The minimum time to obtain a decree of divorce is 1 month, if you hire your advocate wisely who can convince the court to set-off the cooling period.
Otherwise, it can range from 6 months to 18 months from the date of hearing of the case, provided the petition is not withdrawn by either of the party. It is pertinent to note that such divorce can only be obtained after 1 year from the date of marriage. Court provides both the parties a minimum time period of 6 months and a maximum time period of 18 months to make up their minds, cool off and reach a decision as to if they still want a divorce. This time is also called “cooling off period”.
