Pagdi system not taking rent due to landlord family dispute

Dear sir, We have been staying in a flat in thane district since 30 years. The flat is in the name of grandmother. She passed away 10 years ago. Since then my father was paying the rent. Now he also passed away 1 year ago. Landlord has been a good friend of my father. The property is currently having a court case where landlord and his family are having a dispute over who is the actual landlord as it was a gifted property and now after the death of actual owner all her 6 sons and daughters are claiming landlord rights. In admist of this they are refusing to take rent and this has been going for a year now. I request your guidance and support as to how to save my parental house in the future.. where should we pay the rent? How to go about this case? Recently municipality has given a notice about non payment of tax to building.. but seems this is falling on deaf ears. Most of the flats in the building is now onwed by same few sons and daughters and they have given it on rent to some travvellers There are few old first tenants like us and we are poor and helpless Pls throw some light and guidance on this kind of case God bless u and family.
