Will jurisdiction

Hi Learned members,

I purchased a flat in Hyderabad and left for rent. I stay at Chennai. I want to register a will for this property. When I checked where should I register, I get 2 version.

1. The place where the property is located.

2. The residing place of the will giver.

Which one of the above is correct? If I register a will at Chennai, how will the register office at Hyderabad know that there is a will and should avoid any future transactions if something unfortunate happens to the giver.

Thank you
