How Long Does Spousal Support Last in British Columbia?

Spousal support (often called "alimony" elsewhere) in British Columbia has no fixed statutory expiry date. Duration depends on the length of the relationship, the recipient's age and self-sufficiency, and whether support is compensatory or needs-based. The federal Spousal Support Advisory Guidelines (SSAG) provide ranges that most BC courts and lawyers rely on, though these guidelines are advisory, not binding.

How Is Spousal Support Duration Calculated?

Under the SSAG, the most common formula ties duration to the length of cohabitation. For marriages under 20 years, support typically lasts between 0.5 and 1 year for each year you lived together. So a 10-year marriage might produce support lasting 5 to 10 years. Entitlement itself flows from the Family Law Act (for unmarried and married spouses) and the federal Divorce Act (for married spouses seeking divorce). Both statutes direct courts to consider the objectives in section 161 of BC's Family Law Act, including economic self-sufficiency within a reasonable period.

To estimate a possible range for your situation, our spousal support calculator for British Columbia applies SSAG logic to your numbers.

When Does Support Become Indefinite?

Two SSAG rules can produce indefinite (open-ended) support:

• The 20-year rule: Relationships of 20 years or longer generally have no set end date.
• The Rule of 65: If the years of cohabitation plus the recipient's age at separation total 65 or more, duration is indefinite.

"Indefinite" does not mean "forever." It means no automatic end date — support continues until a material change in circumstances, such as retirement, remarriage, cohabitation, or the recipient achieving self-sufficiency, justifies a review or termination.

What Factors Affect How Long It Lasts?

Key considerations include:

• Recipient's age and health — older spouses with limited earning capacity often receive longer support.
• Economic disadvantage from the relationship, such as leaving the workforce to raise children.
• Self-sufficiency efforts — courts expect recipients to pursue reasonable steps toward independence.

Nationally, only about a quarter of divorcing spouses receive any spousal support, and most awards are time-limited rather than indefinite. Reviewing divorce statistics for British Columbia can help set realistic expectations, and our British Columbia divorce resources point you to the correct court forms.

Because duration is highly fact-specific and the SSAG ranges are wide, you should find a family law attorney to assess your entitlement, amount, and likely length before signing any agreement. For more answers to common questions, visit our Divorce Questions hub.
