Can a property dispute be filed directly in Rajasthan High Court?

A, B, and C are three brothers. A sold property to D based on family distribution. A held a power of attorney for B since 1987. The sale deed mentioned all three brothers, but only A executed the deed, and the power of attorney was not referenced. This transaction was completed in 1992. Additionally, A sold another adjacent shop to D in 1997. Both properties were purchased by D. A, B, and C have since passed away. D sold both shops to E in 2004 and has been in possession of the properties since then, with electric and water connections registered in D's name. The properties were rented for an extended period under written agreements. However, the son of B has produced a will from 1984, claiming that the sale chain is invalid. He is threatening us, having broken the locks on the shop and taken possession. Please advise on the legal course of action. Additionally, recommend a good lawyer in Jodhpur or Jaipur. Can this case be filed directly in the High Court of Rajasthan?
