Review/Appeal against decree in Specific perf case

My mom is a plaintiff in a specific performance case for purchase agri land some 20 km from Bangalore. After 13 years in court, we just got the judgment in our favor. Besides decreeing plaintiff case the order awards some 10+ lakhs to be paid by us to vendors (D1-D3). This was a contesetd case and the defendants' position was "we dont know them, we never signed any agrrements, plaintiff fabricated docs etc..". My questions are: a) When there is no balance payable and full consideration was paid (and established thru evidence) 13 yrs back, can court still order award to vendors? Rather than there being any balance payable, we had paid more (about 1.5L) for the vendors to do land survey and fencing which they did not do b) Actually the confusion on the part of the court is that out of the two cheques (1L each) paid to vendors, 1 vendor could not encash (as he did not have proper ID) and he returned the cheque and took cash instead (13 yrs back) ; this cheque and his signed endorsement on the back of the cheque is a marked evidence. The judgment notes ' the cheque was not encashed; there is a due of 1 lakh, ADD TO THIS ESCALATION...' and they have come up with some large number. There is an incorrect appreciation of facts on record. c) If defense has not pleaded hardship can court order award of compensation due to price escalation? I now want to know if I should go for review (praying for correct appreciation of facts on record and eliminate or reduce award of 10+ lakhs) OR for appeal at higher level court. If appeal is it District level court or High Court? What fee is to be paid for Review and appeal? What would be time frame? Also can I file review/appeal and still go for execution simultaneously in the interest of time? I am in total confusion and I would appreciate considered opinion of learned legal persons on this forum. Pranamas in advance....
