Dear vikas speaking morally,
first ask ur uncle that what amount spent by him on maintainance and pay half of that to him.
donot go for court on this pity issue as court will take time in solving these issue.
court may also follow the negotiation path and might ask u to pay the half amount spend by him.
ur case is simple and thus in my view u should not move to court coz it is loss of both time and money.
U have right on the property and u will get it anyhow
I recommend negotiation with uncle.
if the amount is very high then think of moving to court
