How to Change a Custody Order in New Brunswick

Your parenting order was built around your family's circumstances at the time it was made. When those circumstances shift — a new job, a child starting school, one parent relocating — the existing order may no longer serve your child's needs. New Brunswick law allows parents to vary parenting orders, but you need to meet a specific legal threshold and follow the right procedure for your judicial district.

The Legal Standard: Material Change in Circumstances

You can't change a parenting order simply because you want a different schedule. Under both the federal Divorce Act and New Brunswick's Family Law Act, the parent seeking a variation must demonstrate a material change in circumstances — a significant shift that was either not anticipated when the original order was made, or that has fundamentally altered the child's needs.

Examples courts have accepted as material changes include:

• A parent's work schedule changing significantly (shift work, travel requirements)
• The child reaching a developmental stage that requires a different schedule (starting school, teenager needing more independence)
• One parent relocating to a different city or province
• Safety concerns emerging, such as substance abuse or family violence
• A parent consistently failing to exercise their parenting time
• The child's own wishes evolving as they mature

A parent who voluntarily reduces their income or creates instability to manufacture a "change" will face judicial skepticism. Courts look at whether the change is genuine and whether the proposed new arrangement serves the child's best interests.

The Two Paths: Consent vs. Contested Variation

Consent Motion (Form 81I)

If both parents agree on the changes, this is the fastest and least expensive route. In the Saint John and Moncton judicial districts (which operate under Rule 81), parents file a Consent Motion to Change (Form 81I) along with a draft of the proposed new order. There is no filing fee for a consent motion to vary.

The process works like this:

1. Both parents negotiate and agree on the new parenting terms
2. Draft a proposed variation order reflecting the agreed changes
3. Both parents sign the consent motion (Form 81I)
4. File the documents with the Court of King's Bench, Family Division
5. A judge reviews the proposed changes and, if they serve the child's best interests, signs the order without requiring a court appearance

In districts outside Saint John and Moncton (operating under Rule 72), the process is similar but uses the standard motion procedure rather than the Rule 81 forms.

Contested Variation Application

If the other parent opposes the changes, you must file a formal application and be prepared to prove the material change in circumstances before a judge. In Rule 81 districts, this means filing a new application (Form 81A) or a motion within the existing file. In Rule 72 districts, you file a Notice of Motion.

A contested variation typically involves:

• Filing the application with supporting affidavit evidence
• Serving the other parent (at least 27 days before the first court appearance in Rule 81 districts)
• Attending a case conference or first court appearance
• Potentially proceeding to a hearing or trial if the matter cannot be resolved through negotiation

The filing fee for a contested motion is CA$50. If the variation goes to trial, expect additional fees of CA$75 to set the matter down for hearing.

The Child Support Recalculation Service

If your variation involves child support amounts — not the parenting schedule itself — New Brunswick offers a streamlined alternative. The Child Support Recalculation Service can adjust child support payments annually based on updated income information without requiring a court appearance. Both parents submit their current income tax returns, and the service recalculates the Table support amount.

This service only works for straightforward income-based recalculations. If the parenting time split itself is changing (especially near the 40% shared parenting threshold), or if Section 7 extraordinary expenses need revisiting, you'll still need a formal variation through the court.

Common Mistakes to Avoid

Don't just stop following the existing order. Until a new order is signed by a judge, the current order remains legally binding. Unilaterally changing the schedule — even if the other parent informally agrees — leaves you without legal protection if they later claim you violated the order.

Don't wait too long after circumstances change. Courts may question why a parent delayed seeking a variation if the change was genuinely urgent or material. Acting promptly demonstrates that the variation is driven by the child's needs, not strategic timing.

Document the change. Keep records showing when and how circumstances shifted — pay stubs reflecting new work hours, school enrollment notices, communication logs showing the other parent's non-compliance with the existing schedule.

When to Get Professional Help

If both parents agree on the changes and the variation is straightforward, the New Brunswick Child Custody & Parenting Plan Guide includes step-by-step instructions for preparing consent motions and variation documents, along with worksheets to help you map out a revised parenting schedule before filing.

If the variation is contested, or if it involves a relocation that triggers the 60-day notice requirement under Section 16.9 of the Divorce Act, consulting a family lawyer is strongly recommended. An unrepresented parent facing a lawyer on the other side is at a significant disadvantage in variation proceedings.
