Hi
Since your submissions to RDO and other Revenue officials have not yielded the desired results, you should now file a suit for declaratory title based on your sale deed (year 1988) and in the said suit you should implead
1) Your mother , 2) Your brother and 3)Collector and ask the courts for
a)Interim injunction orders against your mother and brother
b) FMB Survey based on your title deed and
c) Rectification of 1B and Patta pass books by collector and other revenue authorities and
c) declare you and your wife the absolute owners of your extent of property.
Hope this information is useful
