A cohabitation agreement is a legal document that sets out financial and property rights between partners. When one person owns the house, it protects both parties by clarifying ownership and contributions. This agreement is especially important in British Columbia, where common-law relationships can create property claims similar to those of married couples. Without clear rules in writing, partners can end up in stressful disputes over ownership and money if the relationship ends.
In this article, we’ll explain what a cohabitation agreement is, why it matters when one partner owns the home, what it should include, and how to create one in BC. You can also hire professional lawyers who will create it for you.
What Exactly Is a Cohabitation Agreement?

A cohabitation agreement is a written contract between two partners who live together or plan to live together. It sets out how property, debts, and financial responsibilities will be handled during the relationship and in the event of a breakup.
Under BC family law, common-law couples who live together for two years or more may have the same rights as married spouses when it comes to property division. That means even if only one partner’s name is on the house title, the other may still have a claim to a share of its value.
Couples usually use a cohabitation agreement when:
- One person owns a home before the relationship.
- One partner brings significantly more assets into the relationship.
- Both want to avoid future legal uncertainty about property division.
Why Is It Important If One Person Owns the House?

When only one partner owns the house, things can get complicated. A cohabitation agreement helps prevent misunderstandings and protects both parties.
Protecting the owner’s equity
- If you owned the house before the relationship, a cohabitation agreement can confirm that you keep ownership and the built-up equity.
- Without one, your partner could potentially claim part of the home’s increased value after living there for two years.
Clarifying partner’s financial responsibilities
- The agreement sets out who pays what. For example, the owner may pay the mortgage, while the non-owner contributes to utilities and groceries.
- This avoids arguments about whether contributions give the non-owner a stake in the property.
Example: Imagine Alex owns a condo and Jamie moves in. Without an agreement, after two years, Jamie could claim a share of the condo’s value. With a cohabitation agreement, it’s clear that Alex keeps ownership, while Jamie’s contributions are recognized in other ways.
What Does a Cohabitation Agreement Include?
A strong cohabitation agreement should cover key financial and property matters to reduce uncertainty later. Common clauses include:
- Ownership of the home: Clearly stating that the property belongs to the titled owner unless otherwise agreed.
- Mortgage payments: Who pays the mortgage and whether those payments create ownership rights for the non-owner.
- Household bills and expenses: Agreement on who pays utilities, groceries, and maintenance.
- Renovations and improvements: If the non-owner contributes to renovations, will they be reimbursed if the couple separates?
- What happens if the relationship ends: Division of assets, financial support, or moving-out timelines.
The goal is to avoid confusion if things don’t work out. Couples can decide in advance what is fair rather than leaving it to a court later.
How Do You Create a Cohabitation Agreement in BC?

The process of making a cohabitation agreement in BC is relatively straightforward, but it requires care to ensure it holds up legally. Family law specialists in BC can also guide you for more.
Step 1: Hire a lawyer.
- While some people use templates, it’s best to consult a family lawyer. They can ensure the agreement follows BC law and covers all key issues.
Step 2: Draft the terms.
- Discuss and write down what both partners want the agreement to say.
- Make sure it’s clear, fair, and detailed.
Step 3: Independent legal advice.
- Both partners should see separate lawyers. This prevents claims of unfair pressure later.
Step 4: Sign the agreement.
- Both partners sign, usually in front of a lawyer or notary.
- Each keeps a copy.
Why independent advice matters:
If a partner later challenges the agreement, courts in BC will check whether both parties had the chance to get independent advice. If they didn’t, the agreement could be weakened.
What Problems Can Happen Without It?
Not having a cohabitation agreement when one person owns the house can create serious problems.
- Property claims: The non-owner may argue they are entitled to a share of the property’s increased value after two years of living together.
- Contribution disputes: A partner who paid for renovations or helped with bills may expect reimbursement or equity, even without their name on the title.
- Emotional stress: Without clear rules, disagreements can turn into expensive court battles.
Example: Sam owned a townhouse before moving in with Taylor. Taylor paid for a major kitchen renovation. When they separated, Taylor claimed a share of the home’s increased value. Without a cohabitation agreement, the case went to court, costing both thousands.
Expert Advice: Is It Fair for the Non-Owner?
Some people worry that a cohabitation agreement only protects the property owner. But when drafted fairly, it protects both partners.
- For the owner: It confirms they keep the property they purchased before the relationship.
- For the non-owner: It ensures their financial contributions are acknowledged. For example, if they pay utilities or help with renovations, the agreement can set out whether they’ll be reimbursed.
Scenario: Chris owns the house, while Jordan pays utilities and groceries. Their cohabitation agreement says Chris keeps the home, but Jordan is protected by reimbursement for certain expenses if they separate. This gives both peace of mind.
Courts in BC prefer agreements that are balanced. If one partner is unfairly disadvantaged, a judge could set it aside. That’s why professional legal advice is so important.
Final Thoughts
So, what is a cohabitation agreement when one person owns the house? It’s a legal document that clearly sets out ownership and financial responsibilities, protecting both partners from costly disputes.
Without one, the non-owner may be able to claim a share of the home after two years of living together, leading to uncertainty and conflict. With one, both parties know exactly where they stand.
Takeaway: A cohabitation agreement is not just about protecting the homeowner. It’s about fairness, clarity, and avoiding future disputes. If one partner owns the house, having this agreement in place is essential.
