No fee shall be charged by any public officer for filing any petition for guardianship or conservatorship under the provisions of Section 17403, or for any official act done or necessary in the course thereof, except that a county employee acting as such guardian or conservator shall be entitled to such costs therefor as will reimburse him in full for moneys advanced by him in such guardianship or conservatorship.

Where a county officer or employee is appointed and acts as such guardian or conservator, the board of supervisors may, by resolution, order that expenses necessary in the conduct of the guardianship or conservatorship and any necessary premiums on the bond of the guardian or conservator be advanced by the county to such guardian or conservator, and such expenses shall be a charge against the county, but the county shall be reimbursed out of any funds or property of the estate of the ward or conservatee.
