Key takeaways
  • A common-law partner can be a spouse for support after 2 years of marriage-like cohabitation, or sooner if the couple has a child together.
  • Entitlement is decided by considering the objectives in s. 161 of the Family Law Act, and amount and duration depend on each spouse's circumstances.
  • An application for spousal support must generally be made within 2 years, running from separation for unmarried spouses.

After a common-law relationship ends, one partner is sometimes left in a much weaker financial position, perhaps after years of caring for children or supporting the other's career. British Columbia's Family Law Act allows spousal support claims by unmarried partners, but there are conditions and a time limit.

This article explains who qualifies, what a court considers, how agreements can affect a claim, and how long you have to apply.

This article covers the law of British Columbia.

Who qualifies as a spouse for support

Under the Family Law Act, a person is a spouse if married, or if they have lived with another person in a marriage-like relationship for a continuous period of at least 2 years. The Act also says a spouse includes a former spouse, so a claim after separation is possible.

There is a shorter route. A person who has lived in a marriage-like relationship for less than 2 years is still a spouse outside the property and pension division parts of the Act if they have a child with the other person. The provincial government confirms spousal support can apply sooner than property division.

You can be separated while still living in the same home. The court may treat one spouse communicating an intention to separate permanently, or an action showing it, as evidence of separation.

What a court considers

If a spouse is entitled to spousal support, the other spouse has a duty to provide it. Entitlement is decided after considering the objectives in s. 161, and the amount is then determined under s. 162. The objectives are:

Amount and duration depend on each spouse's conditions, means, needs and other circumstances, including how long they lived together, the functions each performed while together, and any agreement or order about support. Because these factors turn on each couple's own situation, outcomes depend on the facts. A lawyer can help you gauge what is realistic.

Agreements that release support

A spouse may agree in writing to release the other from spousal support. Where a witnessed written agreement exists, the court may not order spousal support unless the agreement is first set aside under s. 164. It can be set aside for reasons such as non-disclosure of income, property or debts, or if it is significantly unfair.

If you signed a cohabitation or separation agreement, have a lawyer read it before assuming you can or cannot claim.

The time limit to apply

An application for spousal support, as well as property or pension division, must generally be made within 2 years. For unmarried spouses the 2 years run from the date they separated. The period is suspended while the spouses are in family dispute resolution or a prescribed process.

CoupleWhen the 2 years start
Unmarried spousesDate of separation
Married spousesDate a divorce judgment is granted or a nullity order is made

Courts may extend the period in some cases, but do not count on it. If you are close to the deadline, get advice promptly. Be careful with the date of separation too: if you resumed living together primarily to reconcile for periods totalling at least 90 days within one year after separating, you are not treated as having separated.

What to do next

Frequently asked questions

Can I claim spousal support if we lived together less than 2 years?

Possibly, if you have a child together. A person who lived in a marriage-like relationship for less than 2 years is still a spouse outside the property and pension parts of the Act if they have a child with the other person. Without a child, you generally would not meet the test.

Does a common-law partner get less support than a married spouse?

The provincial government says the Family Law Act may apply whether or not you were married, and its support rules generally apply to both married and unmarried couples. A spouse includes a former spouse. The amount depends on circumstances such as how long you lived together.

How long do I have to apply?

Generally 2 years, running from the date of separation for unmarried spouses. The period is suspended while the spouses are in family dispute resolution or a prescribed process.

Can I get support if I signed a release?

A witnessed written agreement must first be set aside before a court can order support. Grounds include non-disclosure of income, property or debts, or significant unfairness. A lawyer can tell you whether your situation fits.
