Alternative to a declaration suit

Dear Sir, I have property in Andhra Pradesh and the property value is very high as it is located in the heart of the city. My relatives, after the death of my father and in my absence, as i was abroad, have created fake documents and lease agreements and encroached upon the property. they have created fake leases with private parties who are hand in golve with my relatives. This has happened almost 1.5 years ago. We have an injunction suit and an order, in force, but the illegal occupants are not respecting the court order, they have constructed commercial structures and making structural changes. some learned people have suggested me to go for a "Declaration of title & recovery of position suit". My financial background is quite poor and I am not in a position to bear the court fee which itself will be several lacs. Is there an alternative solution to my legal problem, experts kindly advise. some of my relatives are infact waiting for me to file a "Declaration suit" so that they can simply become a party to the suit. Please advise.
