(b) Disbursements on motion. Upon motion of any party made after the determination of a motion, or upon its own initiative, the court may allow any party thereto to tax as disbursements his reasonable and necessary expenses of the motion.
(c) Disbursements to party not awarded costs. The court may allow taxation of disbursements by a party not awarded costs in an action or on appeal; and shall allow taxation of disbursements by a party not awarded costs in an action for a sum of money only where he recovers the sum of fifty dollars or more.
(d) Reasonable fees taxable. Where an expense for a service performed, other than a search, is a taxable disbursement, the court may allow its taxation in an amount equal to the reasonable sum actually and necessarily expended therefor, if it is the usual charge made by private persons for the service, although it is in excess of the fee allowed a public officer.
