Compensation payable to a guardian shall not exceed 5% of the income of the ward during any year.
For extraordinary services rendered by the guardian, the Superior Court may, after hearing upon the settlement of his account, authorize additional compensation payable from the estate of the ward, but no compensation shall be allowed on the corpus of an estate received from a preceding guardian.
The guardian may be allowed from the estate of his ward reasonable premiums paid by him to a corporate surety upon his bond.
