Property registration charge and stamp duty in goa

Sir,

Sub: Non-Occupancy Charges of 10% on maintenance bill (excluding Municipal Taxes), is it applicable in South Goa also.

I would like to know if the rule of levying 10% as non-occupancy charges (excluding municipal taxes) for leasing flat on rent is applicable even in the state of Goa. Please advice if the Managing Committee makes their own rules of charging Rs 400/- or more randomly as NOC, are they justified in doing so.
If not, in such a situation can the member seek for justice and what is the procedure to do so in the state of South Goa, Margao.
Thanking you, - Gomes
