(a)

If the court determines that the objections were without reasonable cause and in bad faith, the court may order the objector to pay the compensation and costs of the conservator or guardian and other expenses and costs of litigation, including attorney’s fees, incurred to defend the account. The objector shall be personally liable to the guardianship or conservatorship estate for the amount ordered.

(b)

If the court determines that the opposition to the objections was without reasonable cause and in bad faith, the court may award the objector the costs of the objector and other expenses and costs of litigation, including attorney’s fees, incurred to contest the account. The amount awarded is a charge against the compensation of the guardian or conservator, and the guardian or conservator is liable personally and on the bond, if any, for any amount that remains unsatisfied.
