Diverse of my sister

You should not agree to provide financial help to the husband as that is not your responsibility. He can always go for Medical Insurance if he so require financial assistance.

Secondly, the issue of fraud in marriage will not be of any help as even if that is found to be correct by the Family Court, the marriage will be declared null and void and you are in no mood to get the marriage break as his threat of giving divorce to your sister being resisted, showing you are not ready for the dissolution of the marriage as such.

More so, the marriage itself is about 5 years old as your sister has child of 4 years, the medical condition of the husband even if that was not disclosed at the time of marriage came to your knowledge long back and for the annulment of marriage on the ground of fraud the petition has to be filled with one year of knowledge of the fraud.

The husband has no ground for divorce as such as his wife is very much living with him, so no desertion nor she is inflicting any cruelty on him, rather she suffers cruelty being inflicted on her by him and his parents, the circumstance and facts will not help him to get the marriage dissolved by decree of divorce.
