Protect Your Rights When Living Together
A cohabitation agreement is a legal contract that outlines the rights and responsibilities of unmarried couples who live together. It allows partners to set clear expectations regarding finances, property, and support if the relationship ends.
Many couples sign a cohabitation agreement before moving in together, while others create one after they have already begun living together. When properly prepared and signed, a cohabitation agreement can help prevent disputes and provide certainty if a separation occurs.
In Ontario, cohabitation agreements are recognized as domestic contracts under the Family Law Act. When drafted properly and based on full financial disclosure, they can be legally enforceable..
There is no legal requirement for couples in Ontario to have a cohabitation agreement. However, many couples choose to create one to protect their financial interests and clarify expectations.
A common misconception is that living together creates the same legal rights as marriage. In Ontario, this is not the case.
For example:
- Common-law partners do not automatically share property
- There is no automatic equal division of assets upon separation
- If one partner owns the home, the other does not automatically gain an ownership interest
Because of these differences, a cohabitation agreement can help couples define their financial rights and responsibilities in advance.
What Issues Can a Cohabitation Agreement Address?
A well-drafted agreement can address a wide range of financial and property matters.
Property
A cohabitation agreement can clarify how property will be owned and divided if the relationship ends. This may include:
- Property brought into the relationship by each partner
- Ownership of property acquired during the relationship
- Whether the value of a home will be shared if it increases
- How jointly owned property will be divided
- Whether living in a partner’s home creates any ownership interest
For example, if one partner moves into a home owned by the other, the agreement can clarify whether the non-owner gains any interest in the property.
Financial Responsibilities
A strong cohabitation agreement also outlines how financial responsibilities will be managed during the relationship. This can include:
- Who will pay household expenses
- How rent, mortgage payments, and utilities will be shared
- How savings contributions will be handled
- Responsibility for debts incurred during the relationship
Proper agreements typically include full financial disclosure and independent legal advice for each partner, which helps strengthen enforceability.
Spousal Support
Cohabitation agreements may also address spousal support in the event of separation. The agreement can:
- Set whether support will be paid
- Limit the duration of support
- Define conditions for payment
Courts may still review support provisions in limited circumstances, particularly if enforcing the agreement would be significantly unfair.
Children
A cohabitation agreement cannot waive child support. Under Ontario law, child support is the right of the child. Courts will not enforce provisions that attempt to remove that right. Similarly, parenting arrangements are determined based on the best interests of the child at the time of separation, not in advance through a cohabitation agreement. However, agreements may address whether a party will be financial responsible for child support for the other’s children from a prior relationship in the event of a separation.
Legal Requirements for Cohabitation
Agreements in Ontario
To be valid under Ontario law, a cohabitation agreement must:
For a Valid Agreement
- Be in writing
- Be signed by both parties
- Be witnessed
- Be based on full and honest financial disclosure
If significant assets, debts, or income are not disclosed, a court may set aside the agreement.
Grounds for Invalidity
A court may also invalidate a cohabitation agreement if there was:
- Pressure or duress when signing
- Lack of understanding of the agreement
- Significant unfairness at the time it was made
- Failure to disclose major financial information
Because of these risks, it is important that agreements are carefully prepared.
Estate Planning & Timing
Cohabitation Agreements & Estate Planning
Many couples assume that “common-law” status automatically gives them inheritance rights. In Ontario, this is not the case.
If a partner dies without a will, a common-law partner does not automatically inherit under Ontario’s intestacy laws.
For this reason, cohabitation agreements are often prepared alongside:
- Wills
- Beneficiary designations
- Estate planning documents
Planning ahead can help ensure your partner is protected and your wishes are respected.
When Should a Cohabitation Agreement Be Signed?
Some couples sign a cohabitation agreement before moving in together, while others create one later in the relationship.
Ideally, the agreement should be discussed and finalized before cohabitation begins. However, it can be entered into at any time during the relationship.
If circumstances change, the agreement can also be amended or replaced with a new written agreement signed and witnessed by both partners.

In some cases, courts may provide remedies such as unjust enrichment or constructive trusts, but these claims can be complex and uncertain. A cohabitation agreement can help avoid disputes.

In Ontario, common-law partners may qualify as spouses for support after three years of cohabitation, or sooner if they have a child together and the relationship is of some permanence.
Yes. Certain issues cannot be determined in advance through a cohabitation agreement. Child support cannot be waived or removed, and parenting time and decision-making responsibilities cannot be predetermined in a way that overrides the child’s best interests. However, most financial and property matters can be addressed if the agreement is fair and properly prepared.
A court may set aside a cohabitation agreement if there was:
- Lack of full financial disclosure
- Pressure, duress, or unfair influence
- A failure to understand the agreement
- Improper signing or witnessing

Proper legal guidance can help avoid these issues.

Online templates often do not reflect Ontario family law or the specific circumstances of your relationship. You do not know what you do not know. Online templates can be a good starting point for discussion however agreements that are poorly drafted or not properly executed may be unenforceable. At the very least each partner should receive independent legal advice prior to signing any agreement.
The cost depends on the complexity of the agreement, including factors such as home ownership, business interests, and spousal support provisions. Many straightforward agreements fall within a predictable range. Our office can provide a clear quote after a brief consultation.
Simple agreements may be completed in a few weeks once financial disclosure has been exchanged. More complex matters may take longer. We provide a clear timeline at the beginning of the process.
Independent legal advice means that each partner consults their own lawyer before signing the agreement. The lawyer reviews the terms, explains the legal consequences, and ensures the client understands their rights and obligations. This step significantly strengthens the enforceability of the agreement.
Yes. A cohabitation agreement can be amended or revoked through another written agreement signed by both partners and properly witnessed. Updated financial disclosure and legal advice are recommended when making changes.
If you marry each other, Ontario law generally treats your cohabitation agreement as a marriage contract. Your cohabitation agreement can also explicitly state that the cohabitation agreement becomes a marriage contract in the event of a possible marriage in the future. However, many couples choose to review and update the agreement at the time of marriage.
Yes. The agreement can include provisions relating to property on death and intentions for beneficiary designations. However, it is also important to update your will and beneficiary designations. If a common-law partner dies without a will, the surviving partner does not automatically inherit under Ontario intestacy rules.
Ontario law does not strictly require a lawyer to create a cohabitation agreement. However, having a lawyer draft or review the agreement is strongly recommended. Each partner should obtain independent legal advice before signing. This helps ensure both parties understand the terms and significantly improves the likelihood that the agreement will be enforced if it is later challenged in court.
If common-law partners separate without a cohabitation agreement, property disputes can become complicated. Unlike married couples, common-law partners in Ontario do not have an automatic right to equal division of property. Instead, disputes may be resolved through claims such as unjust enrichment or constructive trust, which can involve complex legal arguments and significant legal costs. A cohabitation agreement can provide clarity and help prevent these disputes.
Ontario courts generally enforce cohabitation agreements if they were properly prepared and meet the legal requirements under the Family Law Act. When reviewing an agreement, courts typically consider whether both partners provided full financial disclosure, the agreement was signed voluntarily, each party understood the terms, and the agreement was properly signed and witnessed. If these requirements are met and the agreement is not significantly unfair, courts will often uphold its terms.
Yes. A cohabitation agreement can include provisions that protect a family business, professional practice, or other business interests. For example, the agreement may clarify that the business remains the property of one partner, that the other partner will not claim an ownership interest, and how business income will be treated during the relationship. This can be particularly important for entrepreneurs, professionals, and family-owned businesses.
Yes. One of the most common purposes of a cohabitation agreement is to protect property that one partner owned before the relationship began. The agreement can clearly identify pre-existing assets such as real estate, investments, savings, and businesses. It can also specify whether any increase in value of those assets will be shared or remain the property of the original owner.
Full financial disclosure means that both partners provide accurate information about their income, assets, and debts before signing the agreement. This may include property ownership, bank accounts and investments, pensions and retirement accounts, and outstanding loans or credit card debt. Failure to disclose significant financial information is one of the most common reasons a court may set aside a cohabitation agreement.
