Couples researching a prenuptial agreement in Calgary want a number before they book a consultation, and most law firm websites don't give one. Part of the reason is real: cost depends on assets, complexity, and how much negotiation the terms need.
Here are the approximate planning ranges based on typical Calgary family law billing patterns, so you can walk into a consultation with realistic expectations instead of a blank guess.
A straightforward prenuptial agreement in Calgary, covering both partners' separate legal fees, falls in the range of roughly $2,000 to $4,000. Add a business, multiple properties, or a high-net-worth estate, and the combined cost can run $8,000 to $15,000 or more. These are general planning ranges, not a quote; your actual cost depends on your lawyer's rate and your specific situation.
A few factors drive the price up or down more than anything else:
| Situation | Typical Total Cost | What Affects the Cost |
| Simple prenuptial agreement with similar assets and no business interests | $2,000–$4,000 | Limited financial disclosure, minimal negotiation, and straightforward drafting |
| Agreement involving real estate, investments, or moderate negotiation | $4,000–$8,000 | More detailed financial disclosure, customized terms, and multiple revisions |
| Complex estate with business ownership, multiple properties, or significant wealth | $8,000–$15,000+ | Extensive disclosure, complex asset protection, and longer drafting and review process |
| Business or professional practice valuation (if required) | $3,000–$10,000+ (in addition to legal fees) | Covers the cost of an independent accountant or business valuator rather than legal services |
These planning ranges are based on typical fee structures at Calgary family law firms and publicly available market information for domestic contracts, not a survey of any specific firm's rates.
Actual fees vary by lawyer, complexity, and how much negotiation the agreement needs. Ask any lawyer you're considering, including firms like THEBIL Family Law, for a written quote or range based on your actual situation.
Alberta's independent legal advice requirement means each partner needs their own lawyer, separate from the other partner's. That's why the cost ranges above cover both sides combined rather than a single fee. A couple sometimes assumes one lawyer can draft the agreement for both partners at a lower combined cost, but a single lawyer representing both sides creates a conflict of interest and may increase the risk that the agreement faces greater scrutiny if it's later challenged.
Family lawyers in Calgary bill domestic contracts one of two ways:
Ask which billing method a lawyer uses before you commit, and get the flat fee or hourly estimate in writing.
Included in a family lawyer's fee, in most cases:
A separate cost on top of legal fees, in most cases:
Not automatically. A higher fee often reflects a lawyer's experience with domestic contracts or the complexity of your file, not a guarantee the agreement will hold up better than a less expensive one.
Price matters less than whether the lawyer treats disclosure and independent legal advice as core parts of the file, not steps to rush through. A cheap agreement missing those elements can cost far more later if it gets challenged.
THEBIL Family Law provides a cost estimate based on a couple's actual assets and situation during the first consultation, rather than a generic number that doesn't reflect what the file involves. Every firm's pricing structure is different, so ask for a written estimate before you proceed with any lawyer you're considering.
A straightforward agreement runs roughly $2,000 to $4,000 combined for both partners' legal fees, as a planning range. Complex situations involving a business or significant assets can run $8,000 to $15,000 or more. Ask a lawyer for a specific quote based on your situation.
Yes. Each partner needs independent legal advice from their own lawyer, so the total cost includes both sides' fees, not one shared fee.
A flat fee gives more cost certainty and works well for straightforward agreements. Hourly billing tends to fit complex files better, since the actual time needed is harder to predict upfront.
Yes. A business adds a separate valuation cost on top of legal fees, along with more complex disclosure and drafting to address how the business gets treated in the agreement.
Many Calgary family lawyers, including THEBIL Family Law, offer an initial consultation to discuss your situation before quoting a fee. Ask when you book whether the first meeting comes at a cost.
Starting early, keeping the couple's assets and terms straightforward, and choosing a lawyer who offers a flat fee for uncomplicated files. Skipping independent legal advice or relying on a template may reduce upfront costs, but it raises the risk that the agreement gets challenged later.
Not directly, but a compressed timeline can push a lawyer toward more billable hours to finish disclosure and drafting on a tight schedule, and it raises the risk that a court later treats the rushed timing as evidence of pressure.
The main additional costs are a business valuation, real estate appraisal, or accounting advice, none of which are part of a family lawyer's legal fee. Ask upfront what your quote covers so nothing comes as a surprise.
For a couple with a business, children from a previous relationship, or a real gap in assets, the cost tends to be smaller than what it would cost to litigate the same property and support questions from scratch during a future separation.
The ranges above are a starting point, not a quote. THEBIL Family Law reviews your actual situation during a consultation and provides a cost estimate based on your assets, your timeline, and what your agreement needs to cover.
