A pleading or other document may be filed by the circuit court only if the filing fee required by law is paid by the person filing the document or a request for a fee waiver or deferral is granted by the court. Filing fees are not refundable under any circumstances. Unless otherwise specifically provided by statute, the filing fee for an action or proceeding is the only fee or charge that may be collected for the filing, whether by the court or any other public body, as defined by ORS § 174.109. [2011 c.595 § 4]
