Does Child Support Change With Shared Parenting in Nova Scotia?

Find out how the 40 percent shared parenting rule under the Child Support Guidelines works in Nova Scotia and why it is not a simple set-off of two amounts.

Key takeaways
  • Section 9 of the Guidelines applies where each parent has the child at least 40% of the time over a year.
  • The court considers each parent's table amount, the increased costs of shared parenting, and the circumstances of the parents and child, so it is not an automatic set-off.
  • Section 7 extras and a different rule for split parenting also matter.

If your children are with you close to half the time, you may have heard that child support simply cancels out. Many parents hear this and assume the lower earner will receive the difference. The rule is more careful than that.

This article explains what the 40 percent threshold means in Nova Scotia, what the court considers once it applies, and how it differs from other arrangements. It does not give dollar figures, because they depend on the current table and on your circumstances.

This article covers the law of Nova Scotia.

What the 40 percent rule says

Under section 9 of the federal Child Support Guidelines, and Nova Scotia's matching section 9, a different approach applies where each parent has the child at least 40% of the time over a year. The measure is time across a year, not a single week or month.

Reaching 40% does not set support at zero or at a fixed discount. It opens the door to a closer look at the finances of both homes. Below that threshold, the usual rule applies: the table amount for the payor's province, plus any section 7 amount.

What the court looks at when the rule applies

When the 40% threshold is met, the court sets support by considering three things:

This is not an automatic set-off. The court looks at the table amount for each parent together with the increased costs and the circumstances of the parents and the child, so the result is not simply one amount subtracted from the other. Two homes mean two sets of bedrooms, clothing, and travel, and a big income gap between parents may matter too.

Each parent's table amount is based on that parent's annual income, worked out starting from the T1 General 'Total income' line, and the court can look at three years or impute income. So both parents' tax records will likely matter.

Extras still count: section 7 expenses

Shared parenting does not remove special expenses. On request, the court may add amounts for child care, the child's share of medical and dental insurance premiums, health costs above insurance of $100 or more a year, extraordinary school costs, post-secondary education, and extraordinary extracurricular activities. These are shared in proportion to the parents' incomes, after any contribution from the child, and subsidies, benefits, and tax deductions or credits are taken into account.

Shared parenting is not the same as split parenting

People often confuse these. Shared parenting is about time with the same child. Split parenting is where there are two or more children and each parent has the majority of time with at least one child. In that case, the order is the difference between the amounts each parent would otherwise pay.

ArrangementHow support is approached
Under 40% with the paying parentTable amount for the payor's province, plus any section 7 amount.
Shared: each parent at least 40% over a yearCourt considers both table amounts, increased costs and circumstances; not automatic.
Split: each parent has majority time with at least one childDifference between the amounts each parent would otherwise pay.

Even in a shared arrangement, a parent can still raise undue hardship, such as unusually high debts or access costs or duties to support others, but the claim fails if the claiming household would have a higher standard of living than the other.

What to do next

Start by tracking time honestly. The 40% figure is measured over a year, so a calendar of actual overnights is more useful than a rough memory. Divorces and the related support, parenting and property issues are heard in the Supreme Court of Nova Scotia (Family Division). Where a court application involving children is filed there, the Parent Information Program is mandatory.

Frequently asked questions

If we each have the children about half the time, does nobody pay?

Not automatically. Where each parent has the child at least 40% of the time over a year, the court considers each table amount, the increased costs of shared parenting, and each parent's and the child's circumstances. It is not an automatic set-off.

Is 40 percent measured by weeks or by the year?

It is measured over a year. Keeping a record of actual parenting time helps show where you land.

Does the lower earner receive support in a shared arrangement?

It can happen, but it is not automatic. The court looks at both parents' table amounts and their circumstances, along with the increased costs of shared parenting. A lawyer can tell you how that may apply to your situation.

Can special expenses like daycare still be added?

Yes, on request. Section 7 allows amounts for items such as child care and extraordinary activities, shared in proportion to income.
