Prenuptial agreements carry an unfair reputation as unromantic or distrustful. In practice, they're a planning tool — one that Alberta's Family Property Act explicitly allows couples to use to opt out of the default property division rules, provided they follow the right process.
What a Prenuptial Agreement Can Address
- How property owned before the marriage will be treated if the marriage ends
- How future property and debt acquired during the marriage will be divided
- Whether spousal support will be waived, limited, or calculated differently than the default framework
- Treatment of a business, inheritance, or specific asset either spouse wants to protect
Prenuptial agreements generally cannot pre-determine parenting arrangements or child support, since those remain subject to the best interests of the child at the time they're decided.
Why "Fairness at Signing" Matters So Much
Alberta courts can set aside a prenuptial agreement — in whole or in part — if it wasn't fair and reasonable at the time it was signed, or if there wasn't proper financial disclosure. This is why simply downloading a template and signing it rarely provides the protection people expect.
What Makes a Prenuptial Agreement Enforceable
- Independent legal advice for each party from their own separate lawyer
- Full and honest financial disclosure from both parties before signing
- Reasonable timing — signing under time pressure right before the wedding can be used to challenge the agreement later
- Terms that were not unconscionable or grossly unfair at the time of signing
Who Should Seriously Consider One
- Anyone entering a marriage with significantly more assets, debt, or income than their partner
- Business owners who want to protect the business from being treated as family property
- People who've been through a previous divorce and want more certainty the second time
Frequently asked questions
Can a prenuptial agreement be changed after marriage?
Yes — couples can enter into a new or amended agreement at any point, provided the same requirements (independent legal advice, disclosure, fairness) are met.
Does a prenuptial agreement expire after a certain number of years of marriage?
Not automatically under Alberta law, but courts do consider whether an agreement has become unfair due to changed circumstances over a long marriage.
Is a handwritten agreement between spouses enforceable?
It's very unlikely to hold up without independent legal advice for both parties and proper financial disclosure — informal agreements carry significant legal risk.
