Check issue

My friend has taken money of 200,000 one year ago and he is not replaying the money. It not that he doesnt have money, he doesn't want to repay... When he took the money he has issued a blank signed check as security , when I told him that I will go to bank to encash, he said that he has already declared that the check is missing to the bank. so it will not be encashed..from some of my sources in bank came to know that the check was issued in his mother's name or accoubt which was declared as missing and he signed and given to me staying it is his check. I am I urgent need of money... does the court of law has any provisions to help me I this case.
