Maintenance & property tax goes to 2 different registered society! Kindly guide

From 15 years maintenance bills Pending, Society was in ambiguity , they came to know my registration information around 2016 through RTI, there is a dispute between two wings, both are different registered society A wing is SRA, {where my property tax comes , due to technical issues physical structure in A wing , hence MCGM charging to A wing, they are not raising bills I have written letter previously as my registration is in free hold part ie. B WING Hence neither property tax nor maintenance has been paid till date. Reasons. 1. There is risk of double jiopardy dual claimants if I sell property then A wing may raise demands towords maintenance. 2. Multiple unit number of the same property, {in both a and b wing different} 3. Unit no.s not mentioned in share certificate to confirm the authority and has ambiguity of society on it's claim. {They argue their demand is valid as our registration is in B wing and we have used water and Society entrance} 4. Probability of property attachment by MCGM of whole A wing , as they have dues of 31 lacs and even if I am ready to pay property tax to MCGM they said they will attach even if I pay directly as bills are not individualised. 5.No guarantee by society to refund if any situation on dual jiopardy. As NOC authority by b wing,. NDC authority by A wing. 6. Not a single minutes are signed till date by any committee, so without resolution Signed committee has not raised bills but due to pressure from members bills are started raising from 2 to 3 years, now expected to receive First bill signed by treasurer and secretary , previous.bills have no sign. No resolution Signed, as ambiguity multiple unit no. As Due to above ambiguity. Moreover society want to charge interest on unresolved matter for which society has not taken any initiative to communicate with MCGM or A wing to sort the dual clemency issue. Query. 1. Can they charge interest if matter is in dispute as above? 2. Is society eligible to raise interest if there are above ambiguity? Many year's bills are not audited yet. 3. Through letter Can we bind them From raising interest in maintenance bill? to keep it in abbeyance due to Abv disputes? or puzzling them by asking resolution of different unit number, NOC and NDC clarification and resolution on double jio pardy situations and asking stand of society for refund if A wing doesn't provide us in NDC in event of selling property? Ps. Secendly. 1st holder was my Mom , died in 2018, neither transmission nor nomination happened yet, certificate shows my name. Can they file 101? As not sure about following. LEGAL HEIR / NOMINEE NOT ADMITTED AS MEMBER When a member expires keeping a huge of amount of Society dues and the legal heirs / nominees also do not pay the dues nor they become complete the necessary formalities to become the member, in such cases also » recovery suit u/s 101 cannot be filed. refer > https://housingsocietytimes.com/maharashtra-chs-act-9/
