The posting suggest deeper issues. Please post complete facts.

On befall of me my son going to give check every after 2-3 months and getting previous receipts this time he did not  deposit check in bank giving different reasons 

new rent act already passed and you have to pay according to market rate we staying there from 70 years  35 Rs till 2002  main truste died and his son take over trust 2003 to 2006 not collected rent of any one and than he increased rent I think 840Rs  and that  collected  according the area so for that was good enough than after every year 10% every yet increased rent we pay now it reach 1840 Rs that was also paid till 2023 March 

now real issue started want us to pay in cash according to sq  feet's renovation  and than his Mahada  architect and contractor will do work not ready to get fund from Mahada for help we all spent lot of money from our pocket  during this 70 yrs

Asking to collect 20 lakhs need to do plaster and on inner if any needed  and he will pay to  Architect and his workers,for his  small building with 3 tanent  so not taking rent

other reason why u  not paid rent in 2 months so now panelty plus increase rent  AS rental low is already passed,threat us to give us notice 

treating all tenant individually one person good relations so paying at a time 6 months to gather other like us who are very soft don't have enough financially weak treating different way our building is at A category heritage area

threating my son that Mom is NRI so I can give notice or increase rent  rocket high

son doing small job with family how can he effort all this thing
