Cohabitation Agreement

A Cohabitation agreement, keys and model of home.

1. What is a Cohabitation Agreement?

A Cohabitation Agreement is a legal contract that defines the rights and responsibilities

of a couple living together in a committed relationship without being married.

It can address matters such as:

Household expenses and shared finances

Property and asset ownership

Debt responsibilities

Spousal support if the relationship ends

This agreement is also known as:

Adult Interdependent Partner Agreement

Common-Law Partner Agreement

Living Together Agreement

A Cohabitation Agreement can also be part of broader estate planning and relationship

documentation.

2. Who Should Have a Cohabitation Agreement?

Any couple living together in a long-term relationship, especially without immediate plans to

marry, should consider a Cohabitation Agreement.

This is particularly important if your relationship may qualify as common law (also referred to as

a de facto relationship or domestic partnership), which can carry significant legal and financial

consequences. Such agreements provide clarity and protection in areas of property, support, and

inheritance.

3. Why Is a Cohabitation Agreement Important?

Having a Cohabitation Agreement is essential for protecting individual interests and minimizing

disputes. It can help you:

Prove the existence of a common-law relationship if required

Clarify financial responsibilities and property division. Establish terms for spousal support or rights

upon separation avoid lengthy and costly legal battles if the relationship ends

It also serves as evidence of your relationship status in situations involving taxation, benefits, and

inheritance rights.

4. How Is a Cohabitation Agreement Different from a Prenuptial Agreement?

Both documents deal with property and financial matters, but they differ in timing and purpose:

A Cohabitation Agreement is for unmarried couples living together.

A Prenuptial Agreement is created before marriage and comes into effect once the couple is legally

married.

5. How Do I Create a Cohabitation Agreement?

A Cohabitation Agreement should be tailored to your specific relationship and circumstances. It

should include:

a) General Information

Full names of both parties

Address and jurisdiction

Date of cohabitation or intended cohabitation

b) Expenses

Specify how household expenses will be handled

Options include splitting expenses equally, proportionally by income, or from a joint account

c) Assets

List separately owned assets to remain individual property

Identify jointly owned assets and determine how they will be divided upon separation

Asset division can be equal, based on contribution, or negotiated otherwise

d) Debts

Specify responsibility for individual and joint debts

This helps avoid disputes and protects one party from another’s prior liabilities

e) Children

If either party has children from a previous relationship or together, include provisions

acknowledging parental responsibilities

Legal rights regarding parenting will remain governed by applicable provincial or territorial law

f) Final Clauses

Consider whether to include terms about spousal support or inheritance rights

Common-law partners may have legal entitlements depending on how long they’ve cohabited

6. Are Cohabitation Agreements Legally Binding?

Yes, a Cohabitation Agreement is legally binding if it meets standard contract requirements:

Offer and acceptance: Both parties must agree to the terms and sign the agreement

Consideration: There must be mutual benefit from the arrangement

Mutual intent: Both parties must intend to create legal obligations

Legal purpose: The terms must not violate any laws or public policy

Capacity: Both parties must be of legal age and mental capacity

If contested, the burden of proving the agreement is invalid lies with the party challenging it.

7. Should the Agreement Be Notarized?

Notarization is not legally required in most Canadian provinces, but it is strongly recommended.

It helps:

Verify the authenticity of signatures

Confirm that both parties understood the agreement at the time of signing

Additional considerations:

Each party should obtain independent legal advice to ensure fairness

Two witnesses are required for each party’s signature

A lawyer can act as a witness and often as a notary

Including a certificate of independent legal advice strengthens the enforceability of the agreement.
