Someone will have agreed when your charge starts whether that’s your promoter or president at the time. Did your promoter put in roads, street lighting etc around your development? If so the Mancommunidad would be looking after them almost straight away.
This charge should have been budgeted for by your administrator as part of every ones community fees, are you saying it is not and now your are being asked for more? Certainly our contribution to the Mancommunidad was agreed by our president at the time and forms part of our overall budget. Don’t forget it’s a community of communities and as such the Mancommunidad has a budget, AGM minutes etc etc which you are entitled to see what does your administrator / president say?
