(a) At any time after an application is filed to commence a guardianship proceeding, a person interested in the estate or welfare of a ward or incapacitated person may file with the county clerk a written request to be notified of all, or any specified, motions, applications, or pleadings filed with respect to the proceeding by any person or by a person specifically designated in the request. A person filing a request under this section is responsible for payment of the fees and other costs of providing the requested documents, and the clerk may require a deposit to cover the estimated costs of providing the notice. The clerk shall send to the requestor by regular mail a copy of any requested document.
(b) A county clerk's failure to comply with a request under this section does not invalidate a proceeding.
