(1) No suit shall be maintained against any person claiming title under a purchase certified by the Court in such manner as may be prescribed on the ground that the purchase was made on behalf of the plaintiff or on behalf of some one through whom the plaintiff claims.
(2) Nothing in this section shall bar a suit to obtain a declaration that the name of any purchaser certified as aforesaid was inserted in the certificate fraudulently or without the consent of the real purchaser, or interfere with the right of a third person to proceed against that property, though ostensibly sold to the certified purchaser, on the ground that it is liable to satisfy a claim of such third person against the real owner.
