I had been allotted two shops by local development authority by a fee licence in 1976. recently I contacted them as they were not depositing rent cheques since a few years.I was told that their file was not traceable.I asked them to rebuild file.Incidentally I also cant trace the license issued but an attested copy by Notary public of local courts is available with me in my file.What is legal validity of this attested copy. Can it be acceptable to department to start rebuilding file.What is required to be done by me and the authority now so things are normalised. I of course have one original letter after issue of licence asking for security deposit for rented shops giving shop numbers and locality.I also have municipal tax deposit challan in original in my name and above property for period 1978 to 1998.And of course water ,electricity connections and sales tax registration number since 1976 in my name on above shops address.
