Dear client,  

As per the information provided, it appears that you want to cancel the marriage which was earlier scheduled for November but has now been rescheduled to 1st June, and you are concerned that the girl's family may take legal action against you and your family.

Under the Hindu Marriage Act, a marriage can be called off either by mutual consent or through a court order. If both parties agree to cancel the marriage, then it can be done easily without any legal action. However, if one party wants to cancel the marriage and the other party is not in agreement, then the matter may need to be resolved through legal means.

Regarding the possibility of legal action against you and your family, it is important to note that if no dowry has been given or taken, then there can be no dowry case filed against you or your family. However, the girl or her family may decide to file a case of breach of promise to marry or mental harassment against you.

It is important to handle the situation.

If you do not want to marry the girl to whom you are engaged, you can call off the marriage.

You can send a letter to her father through your father intimating your decision to cancel the marriage for the reasons that has been relied upon and can even express willingness to bear the expenses of the engagement proportionately.

If they resort to legal action of lodging any criminal complaint of cheating or dowry demand, you can first obtain anticipatory bail and challenge the false case as per law.

You cannot be forced to marry her against your willingness.

They may try to file a cheating or breach of trust criminal case, but they are not maintainable in this situation because you have not demanded any dowry amount but you have clearly expressed the reasons for calling off the marriage in your letter.  

So what do you want to do? Get forced into a marriage because of your 'imagined' fear of legal action? 

Once marriage is performed it wont be cancelled. It can be filed for Nullity of Marriage within one year of marriage. and after one of marriage for Divorce.
