Couples planning a wedding in Calgary want a written agreement before they sign a marriage licence when a business, an inheritance, or a second marriage is part of the picture. Alberta law recognizes these agreements, but only when a lawyer drafts them to meet specific legal requirements. Here is what a prenuptial agreement lawyer in Calgary needs to get right, and how to choose one for your situation.
The best prenuptial agreement lawyer in Calgary drafts agreements that meet Alberta's legal requirements: full financial disclosure, independent legal advice for each partner, and terms that hold up as fair at the time of signing. Look for a Calgary family lawyer who handles domestic contracts as a core part of their practice, not a generalist who drafts one every few years.
Alberta's Family Property Act calls a prenuptial agreement a "family property agreement." Couples who plan to marry use it to set their own rules for dividing property, instead of relying on the Act's default rules. Couples who live together without marrying, recognized in Alberta as adult interdependent partners under the Adult Interdependent Relationships Act, use a similar document called a cohabitation agreement.
Both documents can address:
A signed agreement doesn't guarantee a court will enforce it. Alberta courts look for several conditions before upholding a family property agreement:
A prenuptial agreement drafted without independent legal advice for each partner gives a court a real reason to set it aside.
The process follows a set order, and skipping a step is what creates grounds to challenge the agreement later:
Family law covers divorce, parenting, and property division as broad categories. Domestic contracts are a narrower skill: a lawyer needs to know the disclosure standard courts expect, how to document it, and how to draft support clauses that survive a Miglin analysis years later. Ask how many family property agreements or cohabitation agreements the lawyer has drafted in the past year.
Your prenuptial agreement lawyer represents you, not your partner. Your partner needs a separate lawyer for their own independent legal advice. A lawyer who offers to handle both sides for convenience is building an agreement that a court can unwind later.
Drafting a family property agreement costs less than contested litigation in most cases, but complexity still drives the price: business interests, multiple properties, or a tight wedding timeline all add work. A lawyer worth hiring quotes a flat fee or a clear range before starting.
If either partner owns a business, holds investments, or expects an inheritance, the lawyer needs to know how to document and value those assets inside the agreement. A lawyer without that background can miss a clause that matters later.
Every practising lawyer in the province holds an active licence with the Law Society of Alberta. Its public lawyer directory lets you confirm a lawyer's licence status before you commit.

A prenup sets terms for property and support between partners. It cannot decide matters that belong to a child, because a court reviews those matters based on the child's circumstances at the time the issue comes up, not on what the parents agreed to years earlier. A prenuptial agreement cannot:
A lawyer drafting your agreement should say so before you sign, not promise the document covers more ground than the law allows.
Start earlier than feels necessary. Alberta courts have set aside agreements signed within days of a wedding, treating the timing itself as evidence of pressure. Disclosure, negotiation, and independent legal advice for two people take real time.
Couples who start the conversation months before the wedding date give their lawyers room to draft an agreement that holds up, instead of a rushed one signed the week before the ceremony.
Yes, when they meet Alberta's requirements: independent legal advice for each partner, full financial disclosure, a written and signed document, and fair terms at the time of signing.
A prenuptial agreement applies to couples planning to marry. A cohabitation agreement covers the same ground for adult interdependent partners, Alberta's term for common-law couples. Both work the same way under Alberta property law.
Yes. Alberta courts expect each partner to receive independent legal advice from their own lawyer. An agreement drafted by one lawyer for both partners is far easier to challenge later.
Yes, but a spousal support waiver still faces court review if challenged. Canadian courts apply the Miglin test, which asks whether the waiver still reflects the couple's circumstances when enforcement comes up.
Costs depend on complexity. A straightforward agreement between two partners with modest assets costs less than one involving a business, multiple properties, or a tight timeline before the wedding. Ask a lawyer for a flat fee or a clear range during your first consultation.
Yes. Partners can amend or replace the agreement at any point, as long as the new version meets the same requirements: independent legal advice, disclosure, and a signed written document.
Without one, the Family Property Act's default rules govern property division if the relationship ends. A court decides the split based on those rules rather than terms the couple chose themselves.
Months before, not days before. Alberta courts have treated a rushed signature close to the wedding date as evidence of pressure, which weakens the agreement's enforceability.
Yes, if the agreement fails to meet the legal requirements, such as missing disclosure, missing independent legal advice, or unfair terms at the time of signing. An agreement drafted to meet these requirements from the start is far less likely to face a successful challenge.
An agreement signed too close to the wedding, without proper financial disclosure or independent legal advice, can cost far more to defend later than it would have cost to draft correctly from the start. THEBIL Family Law helps couples prepare legally sound prenuptial and cohabitation agreements that reflect their unique circumstances and comply with Alberta law.
