Later‑in‑life relationships can be a beautiful new chapter. Many people form new partnerships after divorce, separation, or the death of a spouse, often with established careers, adult children, and carefully planned retirement savings. For these couples, living together can be deeply meaningful, but it also raises important legal and financial questions.
This is where cohabitation agreements come in. Understanding what is a cohabitation agreement, the purpose of a cohabitation agreement, and how it applies to older couples can help partners protect what they have built while creating clarity and peace of mind for the future.
This article explains cohabitation agreements for older couples from a Canadian law perspective only, with practical guidance on how to get a cohabitation agreement, whether cohabitation agreements are legally enforceable, and when professional advice can help.
Understanding Cohabitation Agreements
What Is A Cohabitation Agreement?
So, what is a cohabitation agreement?
In Canada, a cohabitation agreement is a written contract between two people who live together in a marriage‑like relationship but are not legally married. Provincial family law legislation allows unmarried partners to enter into domestic contracts that set out their rights and responsibilities during the relationship and if it ends.
A cohabitation agreement typically addresses issues such as property ownership, financial responsibilities, debt, and spousal support. It can also include terms about what happens if the relationship ends due to separation or death.
For older couples, understanding what is a cohabitation agreement is especially important because many partners enter the relationship with significant assets and existing family obligations.
What Is The Purpose of a Cohabitation Agreement?
The purpose of a cohabitation agreement is to provide clarity and certainty. It allows couples to decide for themselves how finances and property will be handled, rather than relying on default legal rules that may not reflect their intentions.
For older couples, the purpose of a cohabitation agreement often includes:
- Protecting assets accumulated before the relationship
- Ensuring inheritances intended for children are protected
- Preserving retirement savings and pensions
- Managing financial responsibilities fairly
- Reducing the risk of conflict if the relationship ends
At its core, the purpose of a cohabitation agreement is not to plan for failure, but to support informed, respectful decision‑making.
Cohabitation Vs Marriage
Cohabitation and marriage are treated differently under Canadian law.
Married spouses are subject to statutory property equalization regimes in many provinces. Unmarried partners can be subject to the same regimes in many provinces, but in some provinces, they’re not. In provinces where statutory regimes do not apply to unmarried couples, property ownership for cohabiting couples is often determined by title, trust claims, or contract law.

This distinction is crucial for older couples. Without a cohabitation agreement, estate and retirement planning can be significantly impacted if the relationship doesn’t work out. These risks are a key reason many older couples explore how to get a cohabitation agreement.
Why Older Couples Should Consider Cohabitation Agreements
Protecting Assets and Retirement Savings
Older couples often enter relationships with homes, investments, pensions, and registered savings plans accumulated over decades.
A cohabitation agreement can clearly define what remains separate property and how any jointly acquired assets will be treated. This is one of the most common reasons older couples consider how to make a cohabitation agreement.
Without an agreement, disputes over ownership or contribution can arise, particularly when one partner moves into the other’s home. It can also create tension with adult children who may be reliant on future inheritances.
Managing Inheritance and Blended Family Concerns
Many older couples have adult children from previous relationships. Balancing the needs of a new partner with existing estate plans can be challenging.
A cohabitation agreement can work alongside a will to clarify expectations around inheritance and prevent unintended outcomes. It helps ensure that assets intended for children or grandchildren are protected while still providing fairness between partners.
Clarifying Financial Responsibilities
Daily expenses, travel, housing costs, and caregiving responsibilities can look very different later in life.
A cohabitation agreement can outline how expenses will be shared, whether one partner will financially support the other, and how major decisions will be handled. This clarity is often central to the purpose of a cohabitation agreement for older couples.
Planning for Health, Illness, or Incapacity
Health considerations become more significant with age. While a cohabitation agreement cannot replace powers of attorney or advance directives, it can clarify financial expectations during periods of illness or incapacity. We suggest considering your estate planning needs and your cohabitation agreement in concert.
How To Get a Cohabitation Agreement for Older Couples
Many couples wonder how to get a cohabitation agreement and whether the process is complicated.
In Canada, the general steps include:
- Having open conversations about finances, assets, and expectations
- Making full financial disclosure
- Deciding how property, support, and expenses will be handled
- Reducing the agreement to writing (we can help with that!)
- Ensuring both partners sign voluntarily
Understanding how to get a cohabitation agreement early can prevent misunderstandings later.
What Should a Cohabitation Agreement for Older Couples Include?
A well‑drafted agreement reflects the realities of later‑in‑life relationships.
Property and Asset Ownership
The agreement should clearly identify assets each partner brings into the relationship and how they will be treated. This may include homes, cottages, pensions, and investments.
Financial Contributions and Responsibilities
Older couples often have different income levels or retirement timelines. A cohabitation agreement can address how expenses will be shared and whether financial support will be provided.
Plans for Separation or Death
The agreement can set out what happens if the relationship ends, including spousal support arrangements or property division. It can also reference coordination with estate planning documents.
