The ABCs of Costs and Family Law Rules

Family Law Rules and the costs associated:

As of July 1, 2004, all family proceedings in Ontario are governed by the Family Law Rules. These costs rules differ in many respects from the Rules of Civil Procedure that previously governed family law proceedings and, hence, distinguish family law from civil cases generally. Increasingly, under the Family Law Rules, the reasonableness of the parties in the conduct of the litigation is just as important a consideration as success.

Rule 24 of the Family Law Rules governs costs and is attached as Schedule A. Under this rule, costs are intended to indemnify successful litigants for the cost of proceedings, encourage settlement, discourage inappropriate behavior in litigation and preserve access to justice. While these policies reflect prior practice, the family court since 2004 has enjoyed less discretion in deciding costs. Judges award costs more frequently and in higher amounts under the Family Law Rules than had been the case under the Rules of Civil Procedure.

Under the Family Law Rules, the guiding premise is that costs should follow the event in all family law proceedings. Courts are directed to award costs to a successful party and should award full indemnity costs where a party is more successful than his or her offer to settle. Such decisions may be made at case conferences or settlement conferences. Offers to settle are, therefore, of critical importance, since an offer can either effectively neutralise a party’s success or result in further penalty to the losing party. That is, a successful party who did not make a reasonable offer to settle will suffer in costs, as will a party who rejected a reasonable offer to settle.

In addition to the differences between the cost consequences in family law and general civil litigation, there are sometimes differences in the cost rules within family law itself, depending upon whether the matters at issue are financial or child related. In custody cases, the courts have adopted a somewhat different attitude, or perhaps simply a more tempered approach, to costs. The underlying rationale for that distinction is the belief that a party should not be discouraged from making a bona fide custody or access claim because of a fear of costs. Hence, no costs should be awarded where both parents present legitimate and meritorious claims. Until recently, the tendency was not to award costs in custody cases, except in extraordinary circumstances where a party has behaved improperly or unreasonably invoked court proceedings. However, that trend seems to be changing. Presently, in family law, costs are more often following the cause in both financial and custody matters.

Frequently Asked Questions - enforcement & modification orders

Each province and territory in Canada has a maintenance enforcement program for family orders and agreements. Additionally, the federal government may refuse to issue a Canadian passport if the applicant is delinquent in child support payments. They also have the authority to garnish wages for the back payments owed. In the USA, the Office of Child Support Enforcement, which is part of the Administration for Children and Families in the Department of Health and Human Services, is now in charge of the federal child support enforcement program.

Yes. In Ontario, existing family law orders (for decision-making responsibility, child support, spousal support, and more) can be changed if there has been a material change in circumstances since the order was made.

To modify an order, you can negotiate an amendment with your former partner, participate in mediation, or bring a motion to change in court. Your family lawyer will help you determine whether you qualify for a motion to change and represent you throughout the variation process.

If you deny court-approved parenting time, it could be a possibility. The court may find you in contempt. You may also have to compensate the other person for any lost parenting time or legal fees they had to pay to enforce the parenting arrangement.

Ex parte motions provide an exemption to the principles of due process in emergencies by allowing you to petition the court without having to give notice or serve the other parties in your case. If the judge issues the ex parte order, it’s only for a limited time.

If you get an order and want to change it, you first need to assess your relationship with the opposing party.

If you both agree, you can apply for a consent order and need not go to court. If you do not, you may seek help from mediators or counsellors who can help you talk things out. If you still do not agree after mediation, you will need to apply to the court to change the order.

You can use this motion if you need to change your order. By filing this motion, you’re asking the court to change something in your final order. It would help if you showed that there has been a substantial change in circumstances since the last court order. You can’t file this motion just because you disagree with the order. You shouldn’t also file this motion too soon after the court releases the final order. If things have changed in your children’s lives, you can ask to modify the order based on those changes. Other samples you can change may include but not be limited to:

  • Spousal support
  • Decision-making issues for the children
  • Issues related to parenting time
  • Child support

Temporary orders may be changed through agreement with your former spouse or through a court order. If you and your spouse are not in agreement about a change you wish to seek, you can make a motion to the court for a modification.

Yes, it is possible to change the initial terms of a separation agreement if you and your spouse agree to the changes and sign a written agreement to change the terms. If your spouse does not agree to change the terms, you can make a court application to change the separation agreement.

No matter what the circumstances surrounding your separation agreement are, our Toronto separation lawyers can help you make changes when you need to.
