Costs in family court

Court: Ontario family courts — court-specific procedure may differ

Costs are a court order requiring one party to pay some or all of another party’s litigation expenses, based on the Family Law Rules and the circumstances of the case.

Family court costs are governed principally by Rule 24. They are not an automatic reimbursement of every dollar spent. The court considers the result, the parties’ conduct, settlement offers and other factors identified by the rules when deciding whether costs should be ordered and in what amount.

Costs can be decided after a motion, conference in some circumstances, trial or other event. A party asking for costs should be able to explain the legal basis and provide the cost information the court requires. A prior offer to settle may affect the analysis under Rules 18 and 24.

Rule 13 — (3.1) of the Family Law Rules addresses the documents that must be included with a party’s financial statement where child or spousal support has been sought. A party should provide an updated Certificate of Financial Disclosure (Form 13A) to the other party with this documentation.

If disclosure cannot be resolved prior to the case conference, the party seeking disclosure must include in their materials a list of the outstanding disclosure in accordance with Rule 13(11.01) of the Family Law Rules . The court may award costs pursuant to Rules 17(18) or 24(7) where a party has failed to comply with their disclosure obligations. Counsel and parties should address all disclosure issues in advance of the settlement conference. Any motions for disclosure must be heard in advance of the settlement conference. More information about financial statements and the documents that shall be exchanged to support a financial statement is available here . 1. Automatic Disclosure Orders Under Rule 8.0.1

Rule 8.0 — .1 of the Family Law Rules directs the court to issue an automatic order when certain claims are made in an Application, Motion to Change or Answer. This order requires parties to comply with their financial disclosure responsibilities.

The party who receives automatic order from the court must serve the order on every other party in the case according to Rule 8.0.1(5). A party who has not made all reasonable efforts to comply with their disclosure obligations in advance of the case conference may be responsible for the other party’s costs. Upon filing the originating materials, parties will receive a reminder to attend a Mandatory Information Program (Rule 8.1) and to provide an updated email address on all court documents.

Rule 57.01 — (6) of the Rules of Civil Procedure requires that, unless the parties have agreed on costs: “every party who intends to seek costs for that step shall give to every other party involved in the same step, and bring to the hearing, a costs outline (Form 57B) not exceeding three pages in length.”

This permits the presiding judge, where feasible, to summarily determine the issue of costs. The overriding principle is that “the court shall devise and adopt the simplest, least expensive, and most expeditious process for fixing costs…” Rule 57.01(7). C. Civil Case Conferences Counsel may request a civil conference with a Judge pursuant to Rule 50.13. A completed Civil Conference Request Form requesting a case conference before a Judge may be sent to CERcivilappointments@ontario.ca . These conferences are ONLY for procedural matters and will not last more than 30 minutes. The time limit will be strictly enforced. The conference may be by telephone or virtually, at the discretion of the Judge. The form must be fully completed, and the terms of the form complied with to be considered. NOTE: Rule 50.13 does not apply to actions governed by the Construction Act: O. Reg. 302/18, s. 10(9). A matter will not be added to the running list or be given a fixed date unless all motion material including responding and reply materials, facta, and compendiums have been filed. D.…

Rule 13 — (3.1) of the Family Law Rules sets out which documents MUST be included with a Financial Statement where child or spousal support has been sought. An updated Certificate of Financial Disclosure must be provided to the other party.

A party who has not made all reasonable efforts to comply with their disclosure obligations may be subject to a cost sanction, directions/terms imposed and/or the adjournment of any motion brought by that party until compliance. In egregious cases, upon motion, continued non-compliance may result in a party’s pleadings being struck or found in contempt of Court. C. Motions to Change The Family Law Rules direct the Court to determine the next steps in a Motion to Change, with a view to ensuring that these motions proceed in the most efficient manner appropriate in the circumstances. The Court is directed to determine the most appropriate process for reaching an expeditious and just conclusion of the case in the circumstances. A new Motion to Change Endorsement form is available here. Parties are encouraged to provide a draft Motion to Change Endorsement form with their materials for the first judicial conference to obtain early direction regarding the most appropriate process for the case.…
