Lady has made her mind to settle the things mutually so quicking within a month because there is nothing left in her hand. She and her child can get ONLY some money on monthly basis or one time settlement decided by judge of court.
Whatever if client is wishing for quicker disposal, ask lady to file joint petition for Void marriage with the same conditions. Make her understand that going for MCD will trouble both the person in future. Make her understand that get the Divoce Decree from her first husband too.
