Key takeaways
  • Under the guidelines formula for cases without dependent children, the amount of spousal support is worked out from the gross income difference between the spouses.
  • BC courts set spousal support by looking at each spouse's condition, means, needs and other circumstances, not just the income on a pay stub.
  • Imputation can apply to a recipient too: an indefinite order may be time-limited or ended if the recipient has not made reasonable efforts toward self-sufficiency.

If your ex has quit a job, taken a lower-paying one, or seems to be earning more than the paperwork shows, the support number can look unfair. Many people in that position ask whether a court can look past reported income and use a higher figure.

That idea is called imputing income. This article explains in plain terms why income matters so much in spousal support, where imputation can come up, and how people usually try to prove what a spouse really earns or could earn. Whether a court will do it depends on the facts, so a lawyer can confirm how it applies to you.

This article covers the law of British Columbia.

What imputing income means

Imputing income is a term used when the income relied on for support is not simply the figure a person reports. When and how a court does this depends on the facts of each case, so it is worth confirming with a lawyer how it could apply to you.

In BC, the court deciding the amount and duration of spousal support must have regard to each spouse's condition, means, needs and other circumstances, including how long the spouses lived together, the functions each performed during the relationship, and any agreement or order about support. That wording is broad, which is why the real picture of a spouse's means can matter more than a single tax return.

Why income changes the support number

The Spousal Support Advisory Guidelines are advisory only and their use is voluntary, and they do not decide whether someone is entitled to support in the first place. Even so, BC's government says most lawyers and judges use them to help set the amount.

Where there are no dependent children, the formula is 1.5% to 2% of the gross income difference for each year of marriage, up to a maximum of 50%. Because the income difference drives the result, a change in either spouse's income figure moves the range.

For example, with a payor earning $100,000, a recipient earning $40,000 and a 10-year marriage, the formula gives a range of $9,000 to $12,000 per year. That is illustrative arithmetic only, not a promise of any outcome. If the payor's real income were higher, or the recipient's lower, the range would change.

Where imputation tends to come up

Fault is generally not considered, but the court may look at conduct that arbitrarily or unreasonably causes, continues or worsens the need for support, or that affects ability to pay. Whether a particular job loss falls into that category depends on the facts.

How people try to prove real income

Courts work from evidence. If you think income is understated, or you are defending against a claim that yours is, the usual starting point is documents showing what has actually happened.

Time limits and what to do next

A spousal support proceeding under the Family Law Act must be started within 2 years after the date a divorce judgment is made for married spouses, or within 2 years after the date of separation for spouses in a marriage-like relationship. That period is paused while the spouses are in family dispute resolution with a professional or in a prescribed process, and the limit does not apply to reviews of spousal support under sections 168 or 169 of the Act. The Divorce Act, section 15.2, contains no time limit for a married or formerly married spouse to apply for spousal support. If you are waiting for your ex to disclose, an interim order may be available on any application under the Family Law Act.

If an order already exists, it can be changed when the condition, means, needs or other circumstances of either spouse have changed, or when new substantial evidence or nondisclosure is discovered.

Frequently asked questions

Can a court only impute income to the person paying support?

Imputation can come up for a recipient as well. An indefinite order may be time-limited or ended on review if the recipient has not made reasonable efforts toward self-sufficiency, and income may be imputed in that situation. How this applies to either spouse depends on your situation, so it is worth confirming with a lawyer.

Is the Spousal Support Advisory Guidelines figure binding?

No. The guidelines are advisory only and their use is voluntary. BC's government describes them as not law, though most lawyers and judges use them to help set the amount.

What if my ex did not disclose all their income?

If a witnessed written agreement was signed, nondisclosure of income, property or debts is one of the grounds on which it can be set aside or replaced. For an existing order or agreement, new substantial evidence or nondisclosure can support a change.

Does it matter that my ex left their job on purpose?

Fault is generally irrelevant, but conduct that arbitrarily or unreasonably affects the need for support or the ability to pay can be considered. A lawyer can tell you how that might apply to your facts.
