The cost of a prenup (marriage contract) in Ontario depends on the complexity of each spouse’s finances, how much negotiation is needed, and whether the lawyer bills hourly or offers a flat fee.

Typical price range

• A lawyer-drafted marriage contract for a couple with straightforward finances commonly costs about $2,500 to $5,000 in legal fees.
• Many Ontario family law firms offer flat-fee packages, often in the range of roughly $1,500 to $3,000 per person, covering an initial consultation, drafting, one round of revisions, and the signing meeting.
• Couples with complex assets, such as a business, multiple properties, or international assets, can expect fees from $5,000 up to $10,000 or more.

Independent legal advice (ILA) costs

Each spouse typically needs a separate lawyer to provide independent legal advice (ILA), since one lawyer cannot represent both sides due to the conflict of interest involved. ILA commonly adds a $1000 to $3000 per spouse, on top of the drafting fee.

An agreement signed without proper financial disclosure or without each party obtaining ILA can be at greater risk to a later challenge under the Family Law Act. If a court sets the agreement aside, the couple could face additional legal costs through litigation trying to resolve any underlying property and support issues.
