Separation Agreements in BC: The Complete Guide

The separation agreement is the document that actually settles your separation — parenting, support, property and debt. Here is what goes in one, what makes it hold, how they get torn up, and what it costs. Written in plain language by family lawyers and mediators in Surrey, BC.

If a separation has one central document, this is it. The divorce order ends the marriage; the separation agreement decides everything you will actually live with. Done well it can keep a family out of court entirely. Done badly it becomes the thing you litigate about five years later.

What a separation agreement is

A separation agreement is a written contract between separating spouses that settles some or all of the issues between them — parenting, child support, spousal support, and the division of property and debt. British Columbia’s Family Law Act expressly encourages separating couples to resolve these matters by agreement, and gives properly made agreements real force.

It is not a filing, a form, or a court process. You do not need a judge’s permission to make one, and making one does not start a court case. Support terms can, however, be filed with the court afterwards so they are enforceable in the same way as an order — covered in the filing section below.

Whether you need one

You need one if you have anything to divide, anyone to support, or children to raise. Which is to say: nearly everyone.

  • Married couples generally sign the agreement first, then obtain the divorce order once the one-year separation period has run. See the complete divorce guide.
  • Unmarried couples never need a divorce order — but if you lived in a marriage-like relationship for at least two continuous years, most of BC’s property and support law still applies. The agreement is the whole of your settlement, and your claim deadline runs from separation rather than from a divorce, so the clock is usually shorter.
  • Couples with no property and no children may genuinely need very little — but a short agreement recording that neither party makes a claim against the other is cheap insurance against a claim years later.

What goes inside

Not every agreement needs every clause. But most disputes we see about old agreements trace back to something in this list that was left out.

Parenting arrangements

Where the children live, the schedule, holidays, decision-making responsibility, travel and passports, and how changes get made.

Child support

The income figures used, the table amount, section 7 special expenses, and an annual disclosure and adjustment clause.

Spousal support

Whether it is payable, how much, for how long, and whether the amount can be reviewed or is final.

Property and debt

Real estate, vehicles, bank and investment accounts, pensions, RRSPs, business interests, and who carries which debts.

The family home

Who stays, who pays the mortgage in the meantime, and the trigger and mechanism for sale or buy-out.

Pensions and RRSPs

Division mechanics, which usually need specific wording and sometimes a separate form to action.

Insurance and estates

Life insurance securing support, beneficiary designations, and how the agreement interacts with your will.

Dispute resolution

A clause requiring mediation before either party can file in court — one of the cheapest clauses you will ever include.

What makes it binding

A separation agreement is a contract, and the formalities matter. Terms dividing property need to be in writing, signed by both parties, and each signature witnessed. Beyond the formalities, three things do the real work of making an agreement durable:

  1. Complete financial disclosure on both sides. This is the foundation. Everything else in this section is secondary to it.
  2. Independent legal advice for each party. Evidence that both people understood what they were giving up.
  3. Terms that are defensible. Not necessarily equal — parties are free to make deals a court would not have imposed — but explicable. An agreement that departs sharply from the norm should say why it does, in the agreement itself.

How agreements get torn up

Courts do not reopen agreements because one party later decides they could have done better. But there are real grounds, and they fall into two groups.

Something went wrong in the making of it. A party failed to disclose significant property or debt; one party took improper advantage of the other’s vulnerability, ignorance or need; a party did not understand the nature or consequences of the agreement; or the agreement is voidable on ordinary contract grounds such as duress or undue influence.

The result itself is significantly unfair. Even where the process was clean, property and spousal support terms can be set aside if the outcome is significantly unfair — weighing how long the agreement has stood, the parties’ intention to achieve certainty, and the extent to which each has relied on it. That last factor is why challenges get harder as years pass.

Child support is treated differently. Because the money belongs to the child, a court can review child support terms regardless of what the parents agreed, and can substitute the Guidelines figure. Read the complete child support guide.

The single strongest protection against all of this is boring and unglamorous: disclose everything, and document that you did.

Independent legal advice

One lawyer cannot act for both of you. Your interests genuinely conflict, and a lawyer who tried to advise both would be unable to advise either properly.

The normal arrangement is that one party’s lawyer prepares the draft, and the other party takes it to their own lawyer for independent legal advice before signing. That lawyer explains what the agreement does, what the alternative outcomes might be, and whether the deal is within a reasonable range — then signs a certificate confirming the advice was given.

Independent advice is not a legal precondition to a valid agreement. It is, however, the difference between an agreement that is hard to attack and one that invites the argument “I didn’t understand what I was signing.” If budget is the obstacle, an advice-only appointment is one of the cheaper things a family lawyer does — see unbundled services.

Four ways to reach an agreement

The law is identical whichever route you take. What changes is cost, speed and how much of the outcome you control. The six steps below apply in all of them.

  1. 1

    Exchange full financial disclosure

    Both parties list every asset, debt, income source and pension, with documents to back them up. This step is not optional — an agreement built on incomplete disclosure is the one most likely to be set aside later.

  2. 2

    Identify what actually needs deciding

    Parenting arrangements, child support, spousal support, division of property and debt. Some families have all five in play; some have two.

  3. 3

    Negotiate the terms

    At the kitchen table, through a mediator, through collaborative practice, or through lawyers. The route changes the cost and the timeline, not the law that applies.

  4. 4

    Have it drafted properly

    The terms are turned into a written agreement with the operative clauses, releases, review provisions and dispute-resolution mechanism spelled out.

  5. 5

    Each party gets independent legal advice

    Separate lawyers, each advising their own client on what the agreement means and whether it is reasonable. Certificates of independent legal advice are normally attached.

  6. 6

    Sign, witness and file

    Both parties sign in front of a witness. Support terms can then be filed with the court so they are enforceable in the same way as an order.

Step 3 is where the routes diverge: negotiating directly, through a mediator, through collaborative practice, or through lawyers. The comparison table in the divorce guide sets out which fits which situation.

Filing it so it can be enforced

An agreement is a contract, and a contract that is breached normally has to be sued on. Support terms are different: a written agreement dealing with child support or spousal support can be filed with the court, after which it can be enforced as though it were a court order — including through the BC Family Maintenance Agency, formerly the Family Maintenance Enforcement Program.

This is a small administrative step with a large practical effect, and it is routinely skipped by people who draft their own agreements. If support is payable under your agreement, ask specifically whether it has been filed.

Agreement or court order?

People often assume a court order is stronger. In practice the choice is more nuanced.

  • An agreement is private, faster, cheaper, and can contain terms a court would not have jurisdiction or inclination to impose. It reflects what you decided rather than what a judge decided.
  • A court order is directly enforceable without filing, is harder to reopen on procedural grounds, and may be the only option where one party will not engage or where there are safety concerns.
  • Both is common. Many families settle by agreement and then have its terms incorporated into a consent order — the negotiated outcome with the enforceability of an order.

Changing it later

Different terms have different degrees of finality, and a good agreement is explicit about which is which.

  • Child support follows income and can always be revisited. Build in annual disclosure and automatic adjustment so it never goes stale.
  • Spousal support can be drafted as final, as reviewable on a stated trigger, or as variable on a material change. This should be a deliberate choice, not an accident of drafting — varying or ending spousal support.
  • Parenting arrangements can be changed by agreement at any time, and by a court where the child’s best interests require it.
  • Property division is generally meant to be final once done.

Where you both agree on a change, record it in a written amendment. Verbal variations are the source of an enormous number of later disputes.

Timeline and cost

At our office a separation agreement typically runs $900 to $8,000, depending on how many of the five issues are live and how much negotiation is needed. A short agreement between parties who already agree sits at the bottom of that range; a full agreement covering a house, a pension, a business and children sits nearer the top.

If the divorce order follows, a simple uncontested desk order divorce is a $2,200 flat fee. Court filing fees are payable to the court separately.

On timing: drafting is quick, negotiation is not. Families who have disclosed and broadly agree are often done in weeks. Through mediation, most need one to four sessions. The step that reliably causes delay is incomplete disclosure, which is why it is step one.

Fees shown are starting points for straightforward matters. Complex circumstances are quoted individually at your consultation, which is free for the first 30 minutes.

The clauses people wish they'd included

  • An annual disclosure and adjustment clause. Without it, child support silently goes stale and someone litigates years of difference later.
  • A mediation-first dispute resolution clause. Requiring mediation before either party can file is one of the cheapest clauses in the document and one of the most used.
  • A mechanism for the house, not just a decision. “She keeps the house” is not a clause. Who refinances, by when, what happens if the lender says no, and how the transfer is documented — those are clauses.
  • Life insurance securing support. Support obligations do not fund themselves if the payor dies. Insurance with the recipient or children named, and proof of coverage on request, closes the gap.
  • Pension division wording. Pensions usually need specific language and often a separate form. A general statement about splitting them can be unactionable when you go to implement it.
  • The estate follow-through. Separation changes who inherits from you and who can make decisions if you become incapable. Update your will, beneficiary designations and powers of attorney at the same time — wills and estates.

Separation agreements — frequently asked questions

Is a separation agreement legally binding?
Yes. A properly made separation agreement is a binding contract, and in British Columbia support terms can be filed with the court so they are enforceable in the same way as a court order. It is not a letter of intent or an informal understanding — it settles the issues it covers.
Do we both need our own lawyers?
One lawyer cannot act for both of you — the interests conflict. The standard arrangement is that one lawyer drafts and the other party takes the draft to their own lawyer for independent legal advice. Independent advice is not strictly required for an agreement to exist, but an agreement signed without it is far easier to attack later, which is why most well-drafted agreements attach certificates confirming each party received it.
Can a separation agreement be overturned?
It can, though not simply because one party later regrets the deal. The usual grounds are procedural — someone failed to disclose significant property or debt, took improper advantage of the other's vulnerability, or did not understand what they were signing. Separately, a court can set aside property or spousal support terms that are significantly unfair, weighing how long the agreement has stood and how much each party has relied on it. Child support terms get their own scrutiny, because that money belongs to the child.
Do we need one if we were never married?
Often more urgently than married couples do. If you lived in a marriage-like relationship for at least two continuous years, most of BC's property and support law applies to you — but your deadline to bring a property or spousal support claim runs from the date you separated, not from a divorce you will never have. Unmarried couples routinely have less time than they expect.
Can we write it ourselves?
Nothing stops you from writing down what you have agreed, and a written record is better than nothing. The risk is in the drafting rather than the intention: ambiguous wording, missing releases, no pension mechanics, no disclosure clause, and support terms that cannot be enforced as written. Homemade agreements are also the ones most often challenged. If cost is the concern, unbundled help with the drafting alone is usually far cheaper than litigating the agreement afterwards.
What if circumstances change after we sign?
It depends on the term. Child support tracks income and can always be revisited. Spousal support may or may not be variable depending on how the agreement is drafted — some are deliberately final, some are reviewable, and that choice should be a conscious one. Property division, once done, is generally meant to be final. A well-drafted agreement says which terms are open to review and on what trigger.
How long does it take?
The negotiation is the variable, not the drafting. Where both parties have disclosed and broadly agree, weeks is realistic. Through mediation, most families need somewhere between one and four sessions. Where disclosure is incomplete or one party is disengaged, it stretches — which is itself an argument for getting the disclosure step done properly at the start.
Does a separation agreement mean we are divorced?
No. The agreement settles parenting, support and property. Only a court order ends the marriage, and you need that order before you can remarry. Most families sign the agreement first and treat the divorce as the paperwork that follows once the one-year separation period has passed.
