dont pay him apenny,you are only obliged to fullfil the tenancy agreement,

Here is what you need to do to jak out:

1- check if he registered this tenancy agreement with the Municipaly,there is an office in RAYAN for such purpose,only then he can take you to court and request the remaining balance,if not,go ahead and cancel the damn cheques.he would not get a single penny off your account.Remeber you can not cancel cheques here unless you report them to the police,so better you close the account all together.
