criminal

my brother creating false documents grabbed my share of property. Aggrieved by his action I have filed a private complaint before the magistrate praying the court to refer my complaint to police. The honble megistrate insted of refering the matter to police directly dealing with the case. Six years over except recording my statement/evidence and cross examination the case has not moved further. Due to carona and closure of courts the case is further delaying. At present my age is 70 years and I'm suffering with serious ailments like Cancer, heart and kidney diseases. I am afraid that I may not live more and my days are counting. At this juncture my question is what happens if something happens to me? Will my brother (accused) go away happily scotfree? Another important factor here to be noted is that I am not having any legal hairs in india to prosecute the case since they areop settled abroad. is there any way to approach the high court for speedy trail at this carona period. please advise what steps I have to take legally?
