Legal standing on this property

We are three brothers. Elder brother is a Plaintiff but the case has been filed by the Younger brother on his behalf while as he being the Defendant no.2 in the case filed in the year 2007. # In one of the registered property with the registrar in the Year 1990 in the name of defendant nos.1 & 2 wherein Plaintiff is the witness to the purchase of this property when my mother was alive. Plaintiff is now claiming this property has been purchase out of parent/father sold property wherein defendant in collusion with Plaintiff is supporting his stand & does not want to cross examine the plaintiff during the trial as he himself has prepared & put the case on his behalf. This case has been put up by them after 15 years. Plaintiff had confirmed before the trial court that it is with his consent this property was purchase in our names & he had signed the documents as a witness. # Here I would like to know the legal stand on the following: a) Impact of law of limitation for Plaintiff claiming after 15 years of property purchased. b) Impact of Benami transaction Act 1988. c) Plaintiff stand before trail court that this property was purchase in the name of Defendants with his consent & he had signed the documents as an witness. Impact on above three points on me for the above matter separately as well as in combination of these points too
