Maintenance claim even after mcd

Today we file mutual divorce petition. In our agreement and in our divorce petition it is mentioned that my wife will not claim any maintenance in future. But as per some recent judgments any agreement against the public law is not valid and women cannot be debarred from maintenance by any agreement. In future after passing the divorce decree if my wife claim any maintenance, whether I can submit the evidences in court that I was ready to take back my wife and I was ready to maintain my wife and without sufficient reason she left my house. Whether such evidences shall be accepted by the court after passing mutual divorce decree. So that I not have to pay any maintenance.
