What a cohabitation agreement covers, what makes it hold up, and how to get one done properly.
Moving in together is exciting. It is also the moment BC family law starts paying attention to your relationship, whether you planned for that or not.
A cohabitation agreement is how you and your partner decide the rules yourselves. This page covers what one can do, what it cannot do, what makes it hold up if it is ever tested, and how the process works from first conversation to signatures.
The short version
A cohabitation agreement, also called a common-law agreement, is a written legal contract between two people who live together, or plan to, in a marriage-like relationship. It sets out how property, finances, and responsibilities are handled during the relationship, and what happens if it ends.
Think of it as the owner's manual for your shared life. You and your partner write it together, before the rules get written for you.
Under BC's Family Law Act, you do not need to be married for the law to treat you like you are. Once you are spouses, the same rules for dividing property and debt, and for spousal support, apply to you as to a married couple.
Our guide to common-law marriage in BC walks through when this status starts, what counts as marriage-like, and the deadlines if you separate.
You and your partner choose the terms. That flexibility is the point.

ASK JOURNEY
We have only been living together for eight months. Is it too early for a cohabitation agreement?
No. Early is the best time. The two-year mark for property division has not arrived yet, so you are setting the rules before they apply instead of rewriting a financial picture that has already grown together. If you have a child together, you may already be spouses for spousal support, which is another reason not to wait. The conversation is also easier when there is less at stake emotionally.
Almost any couple moving in together can benefit. A cohabitation agreement matters most when one or both of you bring in real estate, a business, investments, significant savings, or children from a previous relationship. The more you each have to protect, the more it matters to put the terms in writing before the law creates its own version by default.
The real cost of skipping it: a client story
Cameron and Lisa each owned successful businesses. Cameron also owned real estate worth considerably more than Lisa's assets. Knowing the relationship was rocky, Cameron wanted a cohabitation agreement in place.
Instead of working with a lawyer, Cameron downloaded a template online. When he presented it to Lisa, he told her to sign it or leave. Lisa signed without getting independent legal advice. Cameron believed he had saved himself some money.
Years later, they had two children and separated. Cameron's real estate had grown dramatically in value. Lisa challenged the agreement in court, arguing she had been pressured into signing, that she did not understand it, and that having children had changed their financial situation.
After a lengthy and expensive trial, the judge upheld the agreement. Texts and emails showed Lisa had negotiated the terms, and her earlier sworn statements confirmed she had understood it. Cameron won, but the fight cost him far more than a properly drafted agreement would have.
The lesson: if you are going to have a cohabitation agreement, do it properly. Getting it right costs a fraction of defending it in court.

BC courts want couples to be able to rely on their agreements, so the bar to overturn one is high. It is not unreachable. These are the things that decide whether an agreement stands:
|
In writing, signed, and witnessed |
The Family Law Act protects a written property agreement where each of you signed and each signature was witnessed by at least one other person. One person can witness both. |
|
Full financial disclosure |
Failing to disclose significant property, debts, or other relevant information is one of the most common reasons an agreement gets set aside. |
|
Independent legal advice |
Not a strict legal requirement, but it is the strongest evidence that each of you understood what you signed and chose it freely. |
|
Genuine understanding |
A court can set aside an agreement if a spouse did not understand its nature or consequences. |
|
No pressure or unfair advantage |
A court can step in if one spouse took improper advantage of the other's vulnerability, need, or distress. "Sign or leave" is exactly the kind of fact that invites a challenge. |
Even a well-made agreement can be tested for fairness
A court can also set aside a property agreement that was made properly if it has become significantly unfair. The court looks at how much time has passed since you signed, whether you were both aiming for certainty, and how much you each relied on the agreement.
This is why an agreement signed at 30 may need a fresh look at 40. Children, a new home, a business, or one partner stepping back from work can all change what is fair.
ASK JOURNEY
Do we both need our own lawyers, or can one lawyer help us both?
You each need your own. One lawyer cannot advise two people whose interests may pull in different directions. Separate advice is what shows, years later, that each of you understood the agreement and signed it freely. In the Cameron and Lisa story, the missing advice is what opened the door to a long trial. Independent legal advice is not expensive friction. It is what makes the agreement stick.
Online templates look convenient. In practice, they often miss what BC law requires, leave disclosure undocumented, and use language that was never tested against your situation. Those gaps can cost you everything the template was supposed to protect.
A lawyer drafts around your circumstances, makes sure disclosure is complete and recorded, confirms each of you is choosing freely, and handles the signing and witnessing properly. The goal is an agreement that holds up, not one that merely exists.
Give yourselves time. An agreement rushed through in the week before a move or a wedding is easier to challenge as signed under pressure.
ASK JOURNEY
How much does a cohabitation agreement cost?
It depends on how complex your finances are and how much negotiation is involved. An agreement between two people with straightforward finances costs less than one involving a business, significant real estate, or children from earlier relationships. In almost every case, doing it properly costs a fraction of defending a weak agreement later. A consultation with one of our lawyers will give you a realistic picture for your situation.
A cohabitation agreement reflects your life on the day you sign it. When something significant changes, such as having a child, buying a home, starting a business, or one of you leaving work, revisit it to make sure it still says what you both intend.
The best time to create a cohabitation agreement is before you move in together. The second best time is now.
ASK JOURNEY
We are getting married. Does our cohabitation agreement still work?
Often it can carry forward, but do not assume it. Many agreements are written to continue after a wedding, and some are not. Have your lawyers review it before you marry and update it into a marriage agreement if needed. It is a much simpler job than starting from scratch, and it means the document still matches the life you are building.
Pay attention to the reaction. A cohabitation agreement is not a sign of distrust. It is a sign of maturity. It means you value the relationship enough to protect both people in it.
Verbal promises like "I would never go after your assets" are sincere in the moment. They are not legally binding. Clarity now prevents conflict later, whether your relationship lasts a lifetime or ends in a way neither of you expected.
ASK JOURNEY
My partner thinks asking for a cohabitation agreement means I do not trust them. How do we have this conversation?
Frame it as protection for both of you. The agreement does not assume the relationship will fail. It assumes two adults deserve to know the rules before they share a life. Try asking: if our situations were reversed, would you want clarity? Most people say yes. The discomfort is usually about what the conversation feels like it implies, not what the agreement does. If your partner stays firmly opposed after a calm conversation, that tells you something about how money decisions will be made in the relationship.
