If no legal remedial steps are taken to collect the amount within three years, then the Law of Limitations applies, hence in your instance you do not have a legal remedy available to you to collect your amount. You can take recourse to the legal remedy of bouncing of the cheque if it is not dated, but in that event you will have to prove, with tangible evidence, that you had loaned the amount to him.
There is no remedy, within the due process of law. Of course, the provisions of NI Act 138 and 139 offer you a chance to make use of the blank undated chequefor abuse of the process of the law, if you are so inclined. The outcome, obviously, are uncertain.
