(1) The court may, upon application (with or without notice of application) by the receiving party, order the paying party to make a payment on account of costs to be paid by him upon assessment. Unless the court otherwise orders, the paying party is liable to make such payment on account within 14 days of being ordered to do so. If upon assessment the amount assessed as payable by the paying party is less than the amount paid by him on account, then the excess shall be a debt payable forthwith upon the making of the assessment by the receiving party to the paying party, together with interest at 5% per annum from the date upon which the payment on account was made until the date of repayment.
(2) A party intending to ask the court to make an order under paragraph (1) must provide to the court and serve on all parties affected an itemized schedule of its costs, such schedule to include the information specified in rule 70.11(3)(a) to (c).
