(a) Parties Entitled. Unless otherwise provided by law, these rules or court order, costs shall be allowed as of course to the prevailing party. The action of the clerk in taxing costs is reviewable by the court on motion.
(b) Defendants in Certain Actions. Costs shall be allowed against a defaulting defendant in a replevin action only if the defendant has refused to deliver the subject goods and chattels pursuant to written demand therefor made before commencement of the action. Costs shall not be allowed against a defendant in a quiet title action who defaults or files an action disclaiming any right in the subject property, and a defendant in such action who denies in the answer claiming or ever having claimed any right in the subject property may, by court order, be allowed costs.
(c) Proof of Costs. A party entitled to taxed costs shall file with the clerk of the court an affidavit stating that the disbursements taxable by law and therein set forth have been necessarily incurred and are reasonable in amount, and if incurred for the attendance of witnesses, shall state the number of days of actual attendance and the distance traveled, if mileage is charged. Such costs may include fees paid to a private person serving process pursuant to R. 4:4-3, but not in an amount exceeding allowable sheriff's fees for that service.
(d) Effective Date. If a court allows costs to be taxed later than 6 months after entry of a judgment or order, or when the judgment or order becomes the subject of review or further litigation later than 6 months after it has been finally disposed of, the judgment for costs shall not take effect before the entry in the civil docket.
