Probate Code
Guardians and conservators (aka guardians of the estate) are generally entitled to reasonable compensation for their work. State statutes limit the fees to a certain amount which cannot be exceeded without prior court approval. Others just permit reasonable compensation and allow courts to interpret what constitutes excessive compensation.
The guardian of the person may petition the court for an order directing the guardian of the estate to pay an amount periodically for the provision of the services specified by the court order.
