Demarcation of vested land prior to execute the lease deed.

Xyz  company submitted a proposal   in the year 1993 to district collector in west Bengal for long term settlement  for 30 years of 5.20 acre land. Advance possession was given to the company , execution of lease deed could not be completed as the company failed to pay salami and rent for  the last 24 years.  My query

1. In event of the company pays lease fees etc, Can District collector execute lease deed now without demarcation of land?
2. Can adjunct land owner request the collector for demarcation of land prior to execute the lease deed.?
3. In event of refusal can adjust land owner seek court interference.
