More couples in Alberta are choosing to live together without getting married. While cohabitation is increasingly common, many partners don’t realize that legal rights and obligations can still arise from these relationships.
A cohabitation agreement can help clarify financial expectations, protect assets, and prevent disputes if the relationship ends. In this post, we explain what cohabitation agreements are, how they work in Alberta, and why working with a family lawyer is important.
What Is a Cohabitation Agreement?
A cohabitation agreement is a written contract between two people who live together in a committed relationship but are not married. It outlines how certain legal and financial matters will be handled during the relationship and if the relationship ends.
These agreements often address property ownership, responsibility for debts, financial support between partners, and how assets will be divided upon separation. In Alberta, cohabitation agreements are commonly used by couples who are living together or planning to move in together but want to clarify expectations in advance.
Like a prenuptial agreement for married couples, a cohabitation agreement helps partners define their rights and responsibilities early—before disputes arise.
Who Should Consider a Cohabitation Agreement?
Many couples assume cohabitation agreements are only for wealthy individuals, but they can benefit a wide range of people.
You may want to consider a cohabitation agreement if:
- One partner owns property before the relationship begins
- One partner has significantly more assets or debt
- You plan to purchase property together
- One partner owns a business
- You want clarity around financial responsibilities
- You want to avoid uncertainty if the relationship ends
More Canadians are living together without marriage, and these relationships can still carry legal implications. In Alberta, once a relationship qualifies as an adult interdependent relationship, partners may have legal rights similar to married spouses in certain circumstances.
A cohabitation agreement can help define expectations before those rights arise.
What Is an Adult Interdependent Relationship in Alberta?
In Alberta, the legal term often used instead of “common-law relationship” is an adult interdependent relationship.
Under the Adult Interdependent Relationships Act, two people may be considered adult interdependent partners if they:
- Live together in a relationship of interdependence for at least three years,
- Live together in a relationship of some permanence and have a child together, or
- Sign an adult interdependent partner agreement.
A relationship of interdependence generally means the partners share their lives, are emotionally committed to one another, and function as an economic and domestic unit.
Courts may look at several factors when determining whether such a relationship exists, including:
- How finances are shared
- Living arrangements and household responsibilities
- Whether the couple presents themselves as partners
- The degree of mutual support and commitment
If a relationship qualifies as an adult interdependent relationship, partners may have rights related to property division and financial support under Alberta family law.
How to Deal with Property in a Cohabitation Agreement
One of the main purposes of a cohabitation agreement is to clarify how property will be treated during the relationship and if it ends.
A well-drafted agreement can set out what each partner brought into the relationship, how jointly purchased property will be handled, whether increases in value will be shared, and how debts will be divided. It can also address what happens to the family home if the relationship ends.
Without an agreement, disputes over property can become complex and may require court involvement. Since 2020, Alberta law provides rules for dividing property between adult interdependent partners, similar to those that apply to married spouses.
A cohabitation agreement allows couples to create their own plan for property division instead of relying solely on the default rules under the law.
What’s Covered by a Cohabitation Agreement?
Cohabitation agreements can address many financial and legal matters related to living together.
Common provisions include:
- Property ownership and division
- Debt responsibility
- Financial contributions to shared expenses
- Spousal or partner support
- Management of jointly owned assets
However, certain matters—particularly parenting arrangements and child support—cannot be permanently predetermined in an agreement. Courts will always prioritize the best interests of the child when making decisions about children.
Because each relationship is unique, agreements are typically tailored to reflect the couple’s specific financial situation and goals.
What Makes a Cohabitation Agreement Enforceable in Alberta?
For a cohabitation agreement to be legally enforceable in Alberta, it must meet specific legal requirements.
Generally, the agreement must:
- Be in writing
- Be signed by both parties
- Include independent legal advice for each party
- Include a certificate from each lawyer confirming the advice provided
These requirements help ensure that both individuals understand the agreement and enter into it voluntarily.
Courts may also consider whether:
- Each party provided full financial disclosure
- The agreement was entered into without pressure or coercion
- The terms were clear and reasonable
Failing to meet these requirements can make an agreement more vulnerable to being challenged in court.
The Value of Working With a Family Lawyer
While templates and online resources exist, cohabitation agreements are legal contracts with significant long-term consequences.
Working with a family lawyer helps ensure the agreement complies with Alberta law and reflects your specific situation. A lawyer can guide you through proper financial disclosure, explain your rights and obligations, and help structure terms that are fair and enforceable.
Legal advice is also a key part of making the agreement valid. Without it, there is a greater risk that the agreement could be challenged in the future. A lawyer can also help identify issues that may not be immediately obvious, such as how to address business interests, future property changes, or unexpected life events.
Final Thoughts
Moving in together is an exciting step in any relationship, but it can also have important legal and financial implications.
A cohabitation agreement allows couples to proactively define their rights, protect their assets, and avoid unnecessary disputes in the future. By clearly outlining expectations early, partners can move forward with greater certainty and peace of mind.
If you’re considering living with a partner or want to protect your interests in an existing relationship, speaking with an experienced family lawyer can help you understand your options and create an agreement that works for both of you.
