The clerk of circuit court shall enter in the judgment and lien docket the sum paid and that the judgment is claimed to be a lien in that amount. To preserve the lien upon property situated in a county other than the county where the circuit court that rendered the judgment is located, a similar affidavit and notice shall be filed with the clerk of circuit court for that county and a like entry made upon the judgment and lien docket in that county. The fee of the clerk of circuit court for making the entry is prescribed in s. 814.61(5).
