If you’ve researched prenups at all, you’ve seen the phrase “independent legal advice” (ILA) repeated constantly. It comes up in every article, every lawyer’s recommendation, every enforceability checklist. But what exactly is it, and do you actually need it?
The short answer: it’s not legally required in Ontario, but it’s the single most important step you can take to protect your agreement from being challenged later.
What Is Independent Legal Advice?
Independent legal advice means that each partner consults with their own lawyer, independently of the other partner, before signing the marriage contract. Each lawyer reviews the agreement, explains what the client is agreeing to and giving up, and provides a certificate confirming that the client understood the terms.
The word “independent” is critical. Both partners cannot use the same lawyer. Each person needs their own advisor who is looking out exclusively for their interests. This ensures that neither party can later claim they didn’t understand the agreement or that they signed under pressure.
Why ILA Matters for Enforceability
Ontario’s Family Law Act does not require ILA for a marriage contract to be technically valid. The statutory requirements are simple: the agreement must be in writing, signed by both parties, and witnessed. But courts consider much more than statutory minimums when deciding whether to enforce an agreement. The presence or absence of ILA is one of the most significant factors in that analysis. In the landmark Miglin v. Miglin decision, the Supreme Court of Canada emphasized the importance of the negotiation process, including whether parties had legal advice.

What Happens During an ILA Consultation
A typical ILA consultation takes 30 to 60 minutes. The lawyer will review the draft agreement, explain each clause in plain language, identify any provisions that may be unfavourable to the client, discuss whether the terms are fair and reasonable, explain the rights the client is waiving, and answer any questions. The lawyer then provides a certificate of independent legal advice, which is attached to the signed agreement.
The cost of an ILA consultation in Ontario typically ranges from $300 to $800 per partner. Some lawyers offer flat-fee ILA packages specifically for prenup reviews. It’s a modest investment relative to the cost of the wedding, and relative to the cost of litigating an unenforceable prenup.
When ILA Is Especially Important
While ILA is always recommended, it’s especially critical in certain situations: when there’s a significant power imbalance between partners (financial, educational, or professional); when one partner is giving up substantial rights, such as waiving spousal support; when the agreement involves complex provisions like business valuations or international assets; when one partner is a newcomer to Canada and may not be familiar with Canadian law; and when the agreement was created without a lawyer’s involvement (for example, using an online platform or template).
In all of these scenarios, ILA isn’t just a good idea. It’s essential insurance against future challenges.
Can I Skip ILA If I Used an Online Platform?
Using a reputable online platform significantly reduces the risk of errors, but it doesn’t replace ILA. The platform ensures the agreement is properly structured and province-compliant. ILA ensures each partner personally understands what they’re signing. These are complementary protections, not substitutes. Many couples use a hybrid approach: build the agreement on a platform, then have each partner consult a lawyer for ILA before signing.

Finding a Lawyer for ILA
You don’t need the most expensive family lawyer in the city for ILA. You need a competent family law practitioner who can review the agreement, explain the terms, and provide a certificate. Many lawyers offer flat-fee ILA packages specifically for prenup reviews, which keeps costs predictable.
If one partner is a newcomer to Canada, consider finding a lawyer who speaks their language or has experience with cross-cultural family law. Language comprehension is a factor courts consider when evaluating whether a party truly understood the agreement.
What If My Partner Refuses to Get ILA?
You can’t force your partner to get independent legal advice, but you can strongly encourage it, and you should document that you did. If your partner declines ILA, have them sign a written acknowledgement confirming they were informed of their right to seek legal advice, were given adequate time and opportunity to do so, and chose not to.
This acknowledgement doesn’t guarantee enforceability, but it significantly strengthens the agreement by demonstrating that the decision to forgo ILA was voluntary and informed. Without this documentation, a partner who skipped ILA may later claim they didn’t know they had the option.
Keep in mind that the more one-sided the agreement, the more important ILA becomes. A court reviewing a highly favourable agreement where one party didn’t have legal advice is much more likely to intervene.
