Validity of will

If the house is in the name of the mother, then father cannot make a valid will in respect of it. The mother can only make a will for the house.

Thanks madam, If believe Mother made this will, then after my parents period, I just want to know whether the WILL will stand or my sisters can claim their share.

If the Will is legally valid i.e fulfill the requirements of a valid Will as per law then the Will shall prevail and your sisters will not get any share in the property. If it is not found to be valid then, sisters can claim their share as per intestate succession.

even on white paper a will written by you mother transferring her property on your name with two valid witness signatrue than no one can challenge that it is valid
