Expert guidance on entitlement, duration, amount calculations, and building financial independence after separation

When you separate, the first question is usually: "How will I pay the bills?" or "How much will I lose?"
We strip away the emotion and look at the math. Support is not punishment; it is a calculation designed to bridge the gap between two households.
This guide breaks down both types of support—Child Support (the non-negotiable) and Spousal Support (the negotiation)—so you understand exactly what you're paying, why you're paying it, and how long it lasts.
Entitlement, quantum, and duration
Key Principle: Spousal Support is calculated after Child Support. It is based on a range (not a fixed amount) and requires proof of entitlement. The SSAGs provide guidance, but the final amount is negotiable.
Spousal Support is not automatic. You must prove 'entitlement' based on one of three grounds: (1) Compensatory (you sacrificed your career for the marriage), (2) Contractual (you have a separation agreement or court order), or (3) Needs-Based (you cannot meet your basic needs post-separation). Being married does not automatically entitle you to support.
The critical planning points
Child Support: Completely tax-free. The payor cannot deduct it, and the recipient does not report it as income. This means the full amount goes to the child's benefit.
Spousal Support: Taxable to the recipient and deductible for the payor. This creates a tax arbitrage opportunity: if the payor is in a higher tax bracket, they save more in taxes than the recipient pays, creating a net benefit.
You cannot use the same asset twice. If you divide a pension as part of property equalization, you cannot also use the pension income to calculate Spousal Support. This is called "double-dipping" and courts will prevent it.
Example: If you split a $500,000 pension 50/50 in equalization, the payor's "income" for support purposes must exclude the portion of the pension that was already divided. Otherwise, the recipient gets the asset and the income from that asset.
If you're in a high tax bracket, the tax deductibility of Spousal Support can significantly reduce the net cost. For example, if you pay $3,000/month in Spousal Support and you're in the 50% tax bracket, your net cost is only $1,500/month. This creates a planning opportunity: you may be able to negotiate a higher Spousal Support amount in exchange for a lower property settlement.
The right of the child comes first
Key Principle: Child Support is calculated first, before any other financial obligations. It is based on a rigid formula and cannot be negotiated away.
Child Support is paid by the parent who has the child less than 40% of the time. It doesn't matter if you're married, common-law, or never lived together. If you're a biological or adoptive parent, you have a legal obligation to support your child financially.

Key Principle: Support orders are enforceable by law. If your ex stops paying, the Family Responsibility Office (FRO) has powerful tools to collect. If your circumstances change, you must file a Motion to Change—do not stop paying without a court order.
If your ex stops paying support, you can enforce the order through the Family Responsibility Office (FRO). The FRO has powerful enforcement tools: wage garnishment, seizure of bank accounts, suspension of driver's licenses, denial of passport renewal, and reporting to credit bureaus. You do not need to go back to court—the FRO enforces automatically.
