Subjudice. a case pending in civil applied an application in revenu

Need help as to what is the best alternative.. We stay in mumbai and had filed a Civil suit for decleration injujunction alternative possession for properties.. our suit is pending in civil court, the defendants have always claimed on title, now they have approached revenue with a plaint asking for removing our name which was mutated in 1998 as co owners. also has pleaded land rights by Kul Kayda(tillers day) not directly but via a predecessor in title on some properties and some by ownership. All the properties belonged to us and they dont have any thing to do with it, it was our mistake that we let their names remain in 1998 when they have acknowledge our rights via stamp paper of Rs.10. So now in such a situatation what could be the respite. will we have to fight in both courts, cant we raise a plea of subjudice before revenue? we dont trust revenue dept. Another important aspect is that there was our own family member who was adopted into different family was mutated as KUL (protected tenant during 1957 tillers day) on his own brothers properites, but passed in adoption to another of our relative. So my basic questions are 1) Is there a subjudice aplicable to such proceeding by revenue when suit is pending in civili court specially when the defendants has not pleaded for jurisdicition in civil trial 2) Can I and if so how plea that revenue does not have jurisdicition on matters relating to title or sucession. 3)Important factor is the defendants have also introduce a plea of tillers day in revenue and not in civil trial which is running. 4) how can I stop them from running the trials simultaneously. 5) The RTS application filed after 19 years where I belive limitation is 2 or 6 months please tell me exactly. 6) and what laws attract to the revenue trials
