My wife's grandfather wrongly entered the abbervated name as "Lakshmi" in a land purchased way back in 1987, instead of full name "Mahalakshmi". Now the land is aquired by govt . For getting compensation how to prove Mahalakshmi is Lakshmi?
You show all the relevant papers to the advocate in your area and get his opinion how to get over this name difference.
a gazette notification and a newspaper publication that laxmi is also known as mahalakshmi, may serve the purpose.
Try suggestion of Adv Gupta.
If that does not work, then approach court.
