A couple in Calgary who wants a prenuptial agreement often starts with a search, not a referral, and the search turns up lawyers, notaries, mediators, and online templates all claiming to help. Alberta law names exactly who can make a prenuptial agreement enforceable, and getting that wrong is how an agreement falls apart years later when a partner tries to rely on it.
Here is in detail who handles a prenuptial agreement in Calgary, and why each professional's role matters.
Family lawyers handle prenuptial agreements in Calgary. Each partner's independent legal advice is central to meeting Alberta's enforceability requirements under the Family Property Act, and that advice has to come from their own lawyer.
Notaries, mediators, and financial professionals can support parts of the process, but only a licensed lawyer can give the legal advice a court weighs when it reviews the agreement.
A family lawyer prepares and advises on a prenuptial agreement, known under Alberta's Family Property Act as a family property agreement. For adult interdependent partners, the equivalent document is a cohabitation agreement.
Either way, the document sets out how the couple will handle property and support if the relationship ends, and it needs to hold up if a court reviews it later.
One partner's lawyer drafts the first version in most cases. The other partner takes that draft to a separate lawyer for independent legal advice. Both lawyers need to be licensed with the Law Society of Alberta, which regulates who can practise family law in the province.
A notary public in Alberta, appointed under the province's Notaries and Commissioners Act, can:
However, a notary who isn't also a licensed lawyer cannot:
Signing in front of a notary satisfies the witness requirement. It does not satisfy the legal advice requirement.
| Professional | Role | Required or Optional |
| Family lawyer (each partner's own) | Drafts, reviews, and advises on the agreement; provides independent legal advice | Required for enforceability |
| Notary public or commissioner for oaths | Witnesses signatures, certifies copies | Optional; a lawyer's office can usually handle this instead |
| Mediator | Helps the couple negotiate terms before lawyers finalize the document | Optional |
| Accountant or business valuator | Values a business, pension, or other complex asset for disclosure | Situational, needed when complex assets are involved |
| Financial planner | Helps a partner understand their financial picture before signing | Optional |
No. A lawyer who advises both partners on the same agreement creates a conflict of interest and undermines the independent legal advice Alberta courts require.
Each partner needs a separate lawyer with no connection to the other side of the negotiation.
Not specifically. Alberta law requires the agreement to be:
That witness doesn't have to be a notary.
Many family lawyers handle the signing and witnessing directly in their own office as part of finalizing the agreement.
A mediator can help a couple work out the terms of their agreement, especially when the partners disagree on details but want to avoid an adversarial process.
A mediator isn't a substitute for a lawyer's advice.
Once the couple settles on terms, each partner still needs their own lawyer to:
An online template skips the two elements Alberta courts look for most:
A partner who signs a template agreement without a lawyer's review has little to point to later if the other partner claims they didn't understand what they signed.
Courts have set aside agreements for exactly this reason, and a template offers no protection against that outcome.
Each partner gathers their financial information, sometimes with an accountant's help for a business or investment portfolio.
The couple works out terms directly or with a mediator's help.
One partner's family lawyer drafts the agreement.
The other partner's separate lawyer reviews the draft and advises them on its effect.
Both partners sign in front of a witness, often at one of the lawyers' offices.
Look for a Calgary family lawyer who drafts family property agreements as a regular part of their practice, not one who handles a prenup only when a client happens to ask.

A licensed family lawyer handles the drafting, review, and legal advice for a prenuptial agreement. Alberta requires each partner to have their own lawyer for the agreement to be enforceable.
No. A notary public can witness the signing and certify documents, but drafting the agreement and advising on its legal effect requires a licensed lawyer.
You need your own lawyer. One lawyer advising both partners creates a conflict of interest and undermines the independent legal advice Alberta courts expect to see.
A mediator can help negotiate the terms, but a lawyer still needs to draft the document and provide each partner with independent legal advice before signing.
A paralegal can support a lawyer's file, but the legal advice and final review need to come from a licensed lawyer, not a paralegal acting alone.
A template skips the financial disclosure and independent legal advice steps Alberta courts expect. An agreement built this way carries a real risk of being set aside if it's ever challenged.
Any independent witness can sign, though many couples sign at their lawyer's office, where a lawyer or a staff commissioner for oaths handles it as part of finalizing the document.
Not always. A financial advisor or accountant becomes useful when a partner owns a business, holds significant investments, or needs help valuing an asset for disclosure.
Costs depend on the complexity of the couple's assets and how much negotiation the agreement requires. Ask a lawyer for a flat fee or a clear range during your first consultation.
A prenuptial agreement only holds up if the right professionals handle each part of the process, starting with a lawyer who provides independent legal advice before you sign.
