My mom has been declared mentally incompetent by the courts. My brother had her sign a retainer for an attorney to represent her when this paperwork was filed. The court had already appointed a GAL. This atty charged almost $2000 to attend the GAL's interview with my mom. Can we ask the court to require the attorney prove that he has an actual contractual relationship with my mom ? And when he can't substantiate that, can we ask to be refunded the nearly $8000 we've already paid him?
