A single judge bench of Allahabad High Court held that, a divorce petition is maintainable within 1 year from date of marriage, if there are Pleadings about Exceptional Hardship.

From Para 19, 20 and 21,

19. Where there is a chance of reconciliation, however slight, the cooling period of six months from the date of filing of the divorce petition should be enforced. However, if there is no possibility of reconciliation, it would be meaningless to prolong the agony of the parties to the marriage. Thus, if the marriage has broken down irretrievably, the spouses have been living apart for a long time, but not been able to reconcile their differences and have mutually decided to part, it is better to end the marriage, to enable both the spouses to move on with the life.
20. In the present case, the petitioner (husband) is aged about 34years and the opposite party (wife) is aged about 32 years. They got married on 29.06.2020 and are living separately since 28.10.2020. It is the case of the parties that every effort to resolve their difference failed despite best efforts being made by their family members and other persons of the society. It is further admitted that since both the parties failed to reconcile their dispute they agreed for divorce by mutual consent and entered into a settlement according to which the husband had to pay a sum of Rs. 6,00,000/- to the wife. In the application which was jointly made by both the parties for waiving of the cooling period, it was stated that the husband was in lookout for a job outside of State of Uttar Pradesh and because of pendency of this proceeding, he was not able to join his new job and further the wife also wanted to restart her life after the divorce. In this case marriage was a non starter. Admittedly, the parties lived together only for few months. After which they have separated on account of irreconcilable differences. It is jointly stated by the parties that the efforts at reconciliation have failed. The parties are unwilling to live together as husband and wife.Even after over three years of separation, the parties still wants to go ahead with divorce. As the parties are living separately for more than three years soon after their marriage and they have entered into a compromise to settle their dispute amicably and has agreed for divorce, specially considering the age of the parties, no useful purpose would be served by making the parties wait except to prolong their agony rather it will be useful that both the parties may be given a chance to restart their life afresh after the divorce. It is also admitted, in the present case, that there are no issues out of the wedlock of the parties.
21. The order passed by the Principal Judge, Family Court, Agra is not consistent with the judgment of Supreme Court in case of Amardeep Singh v. Harveen Kaur (Supra) and Amit Kumar v.Suman Beniwal (Supra).
