Plaintiff waived/forfeited her right to disqualify the trial judge on the ground she had worked as an attorney for the defendant county within the last four years because plaintiff did not object or request the judge’s disqualification in response to the judge’s disclosure of her prior employment at the beginning of a hearing on the merits of plaintiff’s petition for leave to file a late claim against the county.  By proceeding to argue the petition on the merits without requesting disqualification, plaintiff waived the disclosed ground for disqualifying the judge.
