Please intimate legal clause for calculation of flat maintenance charges having two type of flats as under:-

1) Eight flats are3BHK having 1269 sq. ft each.
2) Six flats are 2BHK having 828 sq ft. each.

Since last 14 years maintenance were calculated & collected as per square foot from each flat.

But now question arise by Eight flats of 3BHK having 1269 sq. ft that maintenance should be equally for each flat holders.

So please intimate me legal point in the matter.

I have BHK flat having 828 sq ft. & our building is situated in Rajkot (Gujarat)

I want legal solution please.
