Name to register in Rule card.

Dear Sir, Developer having registered Partnership firm with five partners, to develop own father's land as per Rule card. Constructed small building with 4 flats for personal use. Later on They sold three flats & kept one with them for last 10 years. Now they want to sell last flat. Out of five paetners all brothers & sisters, one brother & one sister expired. Remaining 3 partners are running firm as per terms, as in the event of death of any partner, remaining partners can continue & will hv no effect on firm. Partnership is at will. Power of Attorney was given to one partner, who have sold 3flats & got registered since last 10 years. Same partner can sell 4th flat? Though 3 flats are occupied & registered since 10 years., in property card or on Rule card, all 5 partners names are mentioned, after their death. I hv demanded to to transfer flat in my name as per agreed terms & get conveyance done in all our 4 flat owners. Is it safe to get flat registered in my name without having name in prooerty card as it is in other 3 earlier flat owners? Pls give yoir comments. Chetan Desai.
