1. Depending in which Indian state the property is situated, you will have to obtain probate for the Will (if there is an executor appointed in the Will) or letters of administration (if no executor is named in the Will)
2. Probating the Will is mandatory in Mumbai, Chennai and Kolkata. In other places your name can be mutated on strength of the Will itself. So you will have to inquire with the revenue authority about their requirement for mutating your name
3. If plotting is done that means the plot is demarcated and has a separate revenue record
4. You can give a power of attorney to a trusted person in India who can do the procedure of transferring the plot to your name on your behalf
5. If you wish to sell the plot then you can open a NRO account and for the sale transaction its advisable that you are personally present to seal the deal and receive payment consideration from buyer. You can appoint a constituted attorney for this procedure as well but its better to do it personally since money will exchange hands
