Spousal Support Agreements in BC

Settling Support on Paper Instead of in Court

Most spousal support in BC is never decided by a judge. It is negotiated and written down. A spousal support agreement in British Columbia records what you and your former spouse have decided: whether support will be paid, how much, for how long, and what happens when life changes. Support terms usually live inside a broader separation agreement alongside parenting and property.

SiLaw Group Family Lawyers is a boutique family law and mediation firm in South Surrey. Family law is the only kind of law we practise, and we serve clients in English and Punjabi. This page explains what support terms can say, how waivers and review clauses work, and when a court can set support terms aside. For entitlement, amount, and duration, start with our spousal support overview.

What Support Terms in an Agreement Can Cover

Section 163 of the Family Law Act deals directly with agreements about spousal support. An agreement can set out the circumstances under which support will change or end, and the Act expressly includes a spouse living with another person or entering a new relationship (s. 163(1)). A written support agreement that is filed in court is enforceable under the Family Law Act and the Family Maintenance Enforcement Act as if it were a court order (s. 163(3)).

In practice, support terms usually cover the amount and timing of payments, the duration (indefinite, a set period, or until a defined event), the circumstances that change or end support, whether the terms will be reviewed, and how support was balanced against property division.

Waiving Support Entirely

The Family Law Act allows a full waiver: in making an agreement respecting spousal support, a spouse may agree to release the other spouse from liability for spousal support (s. 163(2)). Waivers appear most often where both spouses are self-supporting, or where one accepts more property in exchange for giving up support.

A waiver is legal, but it is not always the last word, because the same Act lets courts set support terms aside in the circumstances described below. Its strength depends on how it was reached: honest financial disclosure, real understanding, and independent legal advice for each spouse. If you are signing or relying on a waiver, treat those safeguards as essential.

Review Clauses vs Fixed Terms

An agreement or order about spousal support may provide for a review (Family Law Act, s. 168). The agreement can say when the review happens, on or after a specified date, after a set period, or after a specified event, and can also name the dispute resolution process, the grounds, and the matters to be considered (s. 168(1)). On a review, a court can confirm the deal, set aside all or part of it, or make a new support order (s. 168(2)), without first finding the circumstances needed to set an agreement aside or vary an order (s. 168(3)).

A fixed term works differently: support simply ends on a stated date or event, which gives both people certainty about the endpoint.

The choice is a real trade-off. A review clause fits when the future is genuinely uncertain, for example when retraining, a house sale, or retirement is coming. A fixed term fits when both spouses value finality over flexibility. Many agreements combine the two.

When Can a Court Set Aside Support Terms?

An agreement does not fully close the courthouse door, but it narrows it. A court may not make a spousal support order while a qualifying written agreement stands, unless all or part of the agreement is first set aside (Family Law Act, s. 165(3)).

Section 164 sets out how that happens. It applies to written agreements with each signature witnessed, though a court can extend it to unwitnessed written agreements where appropriate (s. 164(1), (6)). A court may set aside or replace support terms only if satisfied that at least one of the following existed when the agreement was made (s. 164(3)):

• a spouse failed to disclose income, significant property or debts, or other information relevant to the negotiation;
• a spouse took improper advantage of the other spouse's vulnerability, including the other party's ignorance, need or distress;
• a spouse did not understand the nature or consequences of the agreement; or
• other circumstances existed that would, under the common law, make all or part of a contract voidable.

Even where one of those grounds is made out, the court may decline to act if the replacement order would not be substantially different from the agreement (s. 164(4)).

There is a second route. Even if the signing process was clean, a court may set aside or replace support terms that are significantly unfair, considering the time that has passed, changes in a spouse's condition, means, needs or other circumstances, the intention to achieve certainty, reliance on the agreement, and how far the terms meet the Act's spousal support objectives (s. 164(5)).

The practical lesson: careful process protects agreements. Full and honest financial disclosure, time to consider, and independent legal advice for each spouse. Reaching the deal through mediation also helps.

Frequently Asked Questions

Is a Spousal Support Waiver Final in BC?

Not automatically. The Act permits a release from liability for support (s. 163(2)), and courts cannot order support while a qualifying agreement stands unless it is first set aside (s. 165(3)). But s. 164 lets a court set support terms aside in defined circumstances. A well-prepared waiver is durable; a rushed one is fragile.

Do Our Signatures Need to Be Witnessed?

Each signature should be witnessed by at least one person, and one person may witness both (s. 164(1), (2)). A court can still deal with an unwitnessed written agreement where appropriate (s. 164(6)), but witnessing is the standard practice.

What Is a Review Clause in a Spousal Support Agreement?

A term that schedules a future look at support, on a date, after a period, or on an event such as retirement. The agreement can say how the review happens and what will be considered (Family Law Act, s. 168). A review is not the same as proving a change in circumstances (s. 168(3)).

Can We Change Our Support Agreement Ourselves?

Yes. Two people who made an agreement can replace it with a new one, and many couples update support terms by consent when circumstances shift. Put the change in writing with the same care as the original, including disclosure and independent advice.
