@Ravikant Soni jii,
S.14 of the HMA provides that the, Court may, upon application made to it in accordance with such rules as may be made by the High Court in that behalf, allow a petition to be presented [before one year has elapsed] since the date of the marriage on the ground that the case is one of exceptional hardship to the petitioner or of exceptional depravity on the part of the respondent.
The words, exceptional hardship or exceptional depravity are not defined in the Act, but from the circumstances of the case, it can be inferred whether, it would cause hardship to the petitioner if permission is denied. There may be various judgements in this regard, for eg- in a case of Mutual Concent Divorce - TARUN KUMAR VAISH versus MEENAKSHI VAISH, the Delhi HC have allowed the petition to be presented within 1 year of seperation where the marriage was not consummated, & it was contended that the parties have irreconcilable differences between them and that they will suffer mental as well as physical hardship on account of the continuation of their marriage. It was also submitted that the families of both the parties have already initiated the process of re-marrying them.
