2) The registration fees continue to remain the same (i.e Rs10,000-/-) per gift deed.
3) Any gift deed by Son In Law to Mother in law will attract normal stamp duty(5% of market value of property).
Option 1- Initially you transferring the share of your husband to your name and subsequently transferring the entire flat to your mothers name.
I) Considering the above and assuming the market value of property is Rs10,00,000-/-,
