Limitation Act 1935

In every case of a concealed fraud, the right of any person to bring a suit in equity to recover any land or rent of which he, or any person through whom he claims, may have been deprived by such fraud, shall be deemed to have first accrued at and not before the time at which such fraud is, or with reasonable diligence might have been, first known or discovered: Provided that nothing in this section contained shall enable any owner of lands or rents to have a suit in equity for the recovery of such lands or rents, or for setting aside any conveyance of such lands or rents, on account of fraud, against any bona fide purchaser for valuable consideration who has not assisted in the commission of such fraud, and who at the time when he made the purchase did not know and had no reason to believe that any such fraud had been committed.
