One women acquires her ancestral property long back. She is having 3 daughters and 1 son. From the bottom of her heart, her intention is to distribute the property among dauthers and that she will be revealing to his son from his childhood. The reason for her intention can be known from this statement which often come from her mouth "we must help and strenghten the daughters and the son needs to look after himself". She has more consideration for her son in laws, but it is opposite to her daughter in law.
Before 3.5 years she mortgaged her property to a soceity and while doing so, she got the signature of her son claiming (by saying through a word) that he is the legal heir of this property, and the society insists the signature of the son. Son also signed without reading anything because the one who requests is his own mother. Now to get more money in the property, she again contacted her son (who is staying in a separate rented house as he along with his wife and children were forcefully driven out from the parents home) to get a signature, claiming that the society is insisting son's signature by saying the same statement like "Society is telling that the son is the legal heir". Now the son is not interested to sign as he heard enormorous number of times "you are not having any share in this property" from her own mother's mouth. As this is the case they are threatening the son by saying "if you are not signing then we will deal accordingly" (not stating the full intention of them).
People advised the son, stating that there is no need for your sign to mortgage the property. Hope they have cleverly and cunningly using you as a surety. Now only the son realizes whether the society requested his sign as he is a legal heir or as a surety. Now he is intending to withdraw the sign (surety). Is there any possibility to withdraw the surety. If yes, then how to do it.
Please advice.
