Common-Law Marriage in BC

What it means, what it triggers, and whether you need an agreement.

Journey wearing smaller clear-frame glasses, smiling softly with a calm and approachable expression.


Most people who search "common-law marriage BC" are not looking for a legal lecture. They are trying to answer a practical question: does living together actually create legal obligations? And if it does, what do we do about it?

The short answers are yes, and it depends. This page gives you the plain-language version of how common-law marriage works in BC, who needs to pay attention to it, and whether a common-law agreement is the right move for your relationship.

What common-law status actually triggers in BC

The most important thing to understand is that common-law status in BC is not ceremonial. It is a legal threshold that activates a specific set of rights and responsibilities, whether you intended it or not.

The two-year property threshold

After two years of living together in a marriage-like relationship, BC family law treats you as spouses for the purpose of property division. This means that family property, which generally includes property acquired during the relationship and increases in value to property brought into it, is subject to equal division if you separate.

This does not mean everything you own gets split down the middle automatically. Property division under the Family Law Act is more nuanced than that, and excluded property rules mean that assets you brought in or inherited may be protected. But the framework applies to you, and navigating it without an agreement in place means the default rules govern.

The two-year clock starts from when you began living together in a marriage-like way, not from any formal date. If you are unsure where you stand, a lawyer can help you assess your situation.

The one-year support threshold

If you and your partner have a child together, support obligations can arise after just one year of living together, before the two-year property threshold is reached. Child support obligations apply to all parents regardless of relationship status, but spousal support can also be triggered at the one-year mark when there is a child in the picture.

Is a common-law agreement right for your situation?

A common-law agreement, also called a cohabitation agreement, is a written legal contract that sets out how property, finances, and support will be handled during your relationship and if it ends. It lets you and your partner define your own terms, rather than leaving those decisions to the default rules of the Family Law Act.

Here are the situations where having one in place matters most:

You are bringing assets into the relationship

A home, a business, investments, or significant savings you built before this relationship. A common-law agreement can clearly define what stays yours, what becomes shared, and how increases in value are treated.

You have children from a previous relationship

You want to make sure that assets you intend to pass to your children are protected, and that blended-family finances are handled fairly and clearly for everyone involved.

You and your partner have meaningfully different financial situations

Different incomes, different debts, different savings. A common-law agreement creates a clear, honest framework so that financial differences are addressed directly rather than assumed away.

You want to buy property together

Moving in together is one thing. Buying real estate together adds a layer of legal complexity around ownership, contribution, and what happens if the relationship ends. An agreement that addresses both the relationship and the property is worth having.

You have already been through a rough separation

You know what it costs, financially and emotionally, when the terms were never written down. You are not doing that again.

When a common-law agreement is not the right tool

A common-law agreement is designed for people who are financially independent and want to stay that way. It is not designed for every situation.

  • If you and your partner plan to fully combine your finances and build everything together from a shared starting point, the default rules of the Family Law Act may actually reflect what you want. An agreement designed to keep things separate would work against your intentions.
  • If you are already married, a common-law agreement does not apply to you. What you would want instead is a marriage agreement, also called a post-nuptial agreement, which operates under a different framework.
  • A common-law agreement cannot override child support obligations or make binding decisions about future parenting arrangements. Those are governed by the best interests of the child, which no agreement between adults can pre-determine.

Not sure which category you fall into? That is exactly what a consultation is for. We will help you understand your situation clearly before you commit to anything.

Having the conversation with your partner

For many couples, the hardest part of getting a common-law agreement is not the legal process. It is raising the subject.

The conversation tends to go better when it is framed honestly: this is about protecting both of us, not about distrust. Two financially independent people who care about each other have every reason to be clear about money and property. Clarity is an act of respect, not suspicion.

It also helps to acknowledge that the conversation is uncomfortable. It is. Having it anyway, early, before the stakes feel high, is almost always easier than having it later under pressure.

A partner who responds to a reasonable financial conversation with sustained anger or refuses to engage at all is giving you information about how financial decisions will be made throughout the relationship. That information is worth having.

Your guide to common-law marriage in BC

Journey here. Most people who search for common-law marriage in BC are not looking for a legal lecture. They want to know whether living together actually creates legal obligations, and if it does, what to do about it. Here are the questions we hear most often.

Common-Law Status in BC
Is "common-law marriage" actually a legal thing in BC?
The term is commonly used, but BC law does not actually use those words. What the law does recognize is a "marriage-like relationship." After two years of living together in a marriage-like relationship, you are classified as spouses under the BC Family Law Act, and the same legal framework that applies to married couples applies to you: property division, spousal support, and related obligations. You do not register anywhere. You do not sign anything. It happens automatically by virtue of how long you have lived together.
We have been together for eighteen months and have a child. Does BC law already treat us as spouses?
For the purposes of child support, yes. Once you have a child together and have been living in a marriage-like relationship, support obligations exist regardless of the two-year property threshold. For property division, you are approaching but have not yet reached the two-year mark, though that threshold will arrive. If you do not have a cohabitation agreement in place, now is a good time to get one. The earlier you put the terms in writing, the cleaner the agreement, because you are setting rules prospectively rather than trying to document a financial reality that has already developed.
Do You Need an Agreement
We are planning to build a life together and share everything. Do we still need an agreement?
That depends on what "share everything" means to you and whether you have thought through what happens if circumstances change. A couple who genuinely intends to pool all assets and build a shared financial life may not need a cohabitation agreement, though even then, having a clear understanding of what happens if you separate is worth putting in writing. Where agreements become essential is when one or both partners have meaningful independent assets, children from previous relationships, or financial situations that need protecting. A consultation with a lawyer will help you figure out which category you are in.
What is the difference between a common-law agreement and a marriage agreement?
A common-law agreement, also called a cohabitation agreement, applies to couples who are living together in a marriage-like relationship without being married. A marriage agreement, sometimes called a prenuptial agreement (before marriage) or a post-nuptial agreement (after marriage), applies to married couples. They serve similar purposes, protecting each partner's financial interests and setting clear terms in case the relationship ends, but they operate under different parts of BC family law and have somewhat different requirements. If you are planning to get married, a cohabitation agreement you already have can often be converted or updated to function as a marriage agreement. A lawyer can walk you through the right approach for your timing.
Talking to Your Partner
My partner agreed to get an agreement but keeps putting off the appointment. What should I do?
Set a deadline together and treat it like any other important appointment: book it, put it in both calendars, and show up. Avoidance usually reflects discomfort with the conversation rather than bad faith, and a lawyer-led process gives both of you a neutral structure to work within. If your partner genuinely refuses to engage after multiple attempts to schedule, that refusal is itself meaningful information. A common-law agreement requires genuine consent and independent legal advice from both parties. An agreement signed under reluctance or pressure is one that can be challenged later. You want a partner who participates willingly, or you want to understand clearly why they will not.
