Want to register land.

Basically let's get it like X,Y,Z.
X lended some money to Y i.e. approx 1 cr. 30 lacs.
Y is ready to give his land in return but the land belongs to Z, who's brother of Y and both of them are ready.
But then here's the problem that how X should register the land without getting in trouble of Income Tax.
Please suggest every possible way, Thank You.
