Are Prenuptial Agreements Enforceable In Alberta?

Need To Know

Prenups are enforceable in Alberta if both parties make full disclosure of their financial situations, both parties enter the agreement willingly, the terms are fair and reasonable, the agreement is signed and witnessed, and both parties get independent legal advice.

As couples in Alberta increasingly turn to prenuptial agreements to clarify financial expectations before marriage, one critical question arises: Are prenuptial agreements enforceable in Alberta? The answer is yes, but only if certain legal requirements are met.

In this comprehensive guide, we’ll walk you through what a prenup is, how it works, and how to ensure that yours is enforceable under Alberta family law.


What Is A Prenuptial Agreement In Alberta?

A prenuptial agreement, commonly known as a prenup, is a written contract made between two people before they get married. In Alberta, these agreements are legally referred to as “domestic agreements” under the Family Property Act.

Prenups allow couples to decide in advance how they’ll handle property division, debt, and spousal support during their relationship and in the event of separation, divorce, or death. They give partners greater control over their financial futures and provide clarity and peace of mind.


How Does A Prenuptial Agreement Work?

Wondering how a prenuptial agreement works? A prenup works by setting out the couple’s financial rights and obligations before marriage. It can:

  • Protect assets acquired before the relationship
  • Define how property will be divided if the relationship ends
  • Outline whether spousal support will be paid
  • Address the treatment of family businesses, pensions, or inheritances

Prenups cannot deal with parenting arrangements or child support, as these must be based on the child’s best interests at the time of separation.

The agreement must be in writing, signed, witnessed, and it should meet specific legal standards to be enforceable in Alberta.


Is A Prenuptial Agreement Legally Binding In Alberta?

Yes, a prenuptial agreement is legally binding in Alberta as long as it meets certain criteria. Courts in ABgenerally respect and enforce agreements that are made fairly and in accordance with the Family Property Act.

However, not all prenups are automatically enforceable. A court can set aside an agreement if it finds issues such as unfairness, lack of disclosure, or coercion. That’s why it’s critical to draft the agreement carefully and with proper legal support.


How Alberta’s Prenup Laws Differ from Other Provinces

While all provinces have laws that allow couples to enter into prenuptial agreements, Alberta’s family law has some unique features:

  • Automatic property sharing rules: In AB, each spouse is generally entitled to half of family property and is responsible for half of family debt, regardless of who paid for it. A prenup lets couples opt out of this default regime.
  • Family Property Act: AB’s Family Property Act governs prenuptial agreements and gives courts discretion to set aside parts of an agreement if they’re found to be significantly unfair.
  • Common-law inclusion: AB’s laws treat many common-law couples the same as married couples when it comes to property division, so prenups are relevant even if you don’t plan to legally marry.
  • Independent legal advice is required: In order for your prenup to be enforceable, both partners have to review the agreement with their own lawyers to ensure that they fully understand and agree to its terms.

Understanding these laws is essential when drafting a prenup that’s enforceable in Alberta.


Legal Requirements For A Valid Prenup In Alberta

To ensure your prenup is enforceable in AB, it must meet these key legal requirements:

Full Financial Disclosure

Both parties must fully disclose their financial situation, including income, debts, assets, and liabilities. Hiding or misrepresenting information can result in your prenup being declared invalid and unenforceable.

Voluntary Consent (No Duress or Coercion)

The agreement must be entered into freely and voluntarily. If one party was pressured into signing or didn’t have enough time to review the agreement, a court may find that they signed under duress. Presenting someone with a prenup days before the wedding is not a good plan.  Start the conversation early.

Fair and Reasonable Terms

Courts in Alberta will assess whether a prenup is significantly unfair at the time it is being enforced. Unconscionable or one-sided terms could be struck down, especially if circumstances have changed significantly since the agreement was signed.

Proper Signing and Witnessing

The prenup must be:

  • In writing (verbal agreements are hard to prove in court)
  • Signed by both parties
  • Witnessed properly (by a competent adult who is not a party to the agreement)

Independent Legal Advice

Each person should get independent legal advice before signing. This ensures that both parties understand their rights and the implications of the agreement. Independent legal advice is strictly required in Alberta, and it’s one of the strongest protections against future challenges. We’ve included a certificate of independent legal advice form as part of every Jointly agreement that you can take to a lawyer in your area to have completed.


When Can A Prenup Be Challenged In Alberta?

A prenup can be challenged and potentially set aside in AB if:

  • There was a lack of financial disclosure
  • One or both parties didn’t receive legal advice
  • The agreement was signed under pressure or threat
  • The terms are significantly unfair
  • Circumstances have changed, and the agreement now results in undue hardship

If any of these conditions apply, a court may declare the prenup invalid or modify its terms.

That’s why it’s crucial to ensure your agreement is well-drafted and revisited if your circumstances change, like having children, moving provinces, or changing careers.


Tips for Making a Prenup Enforceable in Alberta

Here’s how to create a prenup that’s enforceable and stands the test of time:

  • Start early: Avoid last-minute agreements that can be seen as coercive.
  • Be transparent: Lay out all financial information openly. We have created a free financial disclosure worksheet to help you through this so you can get started today.
  • Use clear language: Avoid legalese. Clarity helps both partners understand the agreement and avoids confusion later.  We’ll take care of this for you if you use Jointly to make your agreement.
  • Keep it fair: Avoid extreme or punitive clauses.
  • Include a review clause: Agree to revisit the agreement periodically or when major life events occur. We’ve included a review form with every Jointly agreement.
  • Get independent legal advice: This is strictly required in order for your agreement to be enforceable..  We have included a certificate of independent legal advice form with every Jointly agreement that you can take to a lawyer in your area.
