I booked a plot and paying regular installment for that plot which is based on the completion and development of that site area. After completion of that as i hve deposited complete due amount with the develpoers the plot got registered with me. for exapmle i started paying installmet on 01.0194 and plot got registed on 31.12.98. during the span of four year period i paid RS 5,00,000.00 in each year.....
Now can i index the cost for each year or it can be done only at the when plot was registered........
plz mention if any case law is there related to these facts......
