Dear Experts!
'Y' is planning to purchase a constructed house from 'A' which is construction permission from Gram Panchat Authorities.
'A' puchased the constructed house in 2008 from 'B' with a registered sale deed.
'B' purchased a open plot from it from 'C' with a registered sale deed in 2002 and constructed a house in 2008.
'C' purchased the open plot from 'D' in 1992.
'D' puchased the open dry landland to the extent of one acre from 'E' on the capacity of Pattedar of that land.
The schedule property is in two survey Nos.
As per the revenue records E is the right for only one survey No out of Two survey Nos.
Is it valid document? Can Y puchase it? is there any limitation period to any concern person to challenge the sales?
