my friend has purchased one house through sale deed which was registered in 2015. but patta is not transfered to his name . now municipality without notice , coming for demolistion of house for reason of encroachment of govt land. but he has all land records and survey number for his house. now can he file a writ in HC in his name on basis of sale deed ( doubt is ..patta is not transfered to his name ) or previous owner whose name is in patta.
