How much does a cohabitation agreement cost to have drafted in Ontario?
The cost varies depending on the complexity of the couple's financial situation, whether both parties negotiate or simply sign what one party's lawyer prepares, and the billing model of the lawyers involved. As a general guide in Ontario, straightforward cohabitation agreements where both parties' finances are uncomplicated and they largely agree on terms commonly range from a few hundred to a few thousand dollars in total legal fees — but more complex situations (business interests, multiple properties, competing support positions) can cost more.
Both parties should engage their own lawyers. Each lawyer charges separately. The total cost of the agreement is the sum of both lawyers' fees. Some lawyers offer flat-fee domestic contract services for less complex agreements, which can make costs more predictable.
The comparison point is important: the cost of a properly drafted cohabitation agreement is almost always far less than the cost of litigating a property dispute or support claim at separation without one. Family litigation in Ontario can be very expensive and take years. A cohabitation agreement is a one-time investment in clarity.
If cost is a concern, discuss the scope with your lawyer upfront to understand what level of complexity you are paying for. Legal Aid Ontario generally does not cover domestic contracts, but some community legal clinics can assist lower-income individuals with simpler matters.
