A prenuptial agreement (marriage contract) in New Brunswick typically costs between $1,500 and $5,000 per spouse for legal drafting and independent legal advice, with complex agreements involving business interests or significant assets reaching $10,000 or more per party. Under Marital Property Act, RSNB 2012, c. 107, s. 35, a valid marriage contract must be in writing, signed by both parties, and witnessed. Because each spouse should retain separate counsel to satisfy the independent legal advice requirement under s. 41, the total prenup cost in New Brunswick for a couple typically ranges from $3,000 to $10,000 combined.

What Determines Prenup Cost in New Brunswick
The prenup cost in New Brunswick depends on four primary factors: the complexity of each spouse's financial situation, the hourly rate of the family lawyer, whether contested terms require negotiation, and whether both parties obtain independent legal advice. A straightforward agreement covering a modest home and basic savings typically costs $1,500 to $3,000 per spouse, while agreements addressing business valuations, real estate portfolios, or professional practices cost $5,000 to $10,000 or more per spouse. New Brunswick family lawyers charge between $250 and $600 per hour as of 2026, with most prenuptial agreements requiring 6 to 20 hours of legal work depending on negotiation complexity.
The number of assets requiring valuation directly impacts cost. Each additional property, business interest, or investment account adds approximately $500 to $1,500 in legal time for proper drafting. Couples who arrive at their lawyer's office with a preliminary written agreement on key terms can reduce billable hours by 20% to 30%, bringing the total prenup cost in New Brunswick toward the lower end of the range.
Prenup Lawyer Fees in New Brunswick: Detailed Breakdown
New Brunswick prenup lawyer fees range from $1,500 for a simple agreement to $10,000 or more for complex high-net-worth contracts, with most couples paying between $3,000 and $6,000 total for both parties combined. These fees cover the initial consultation ($250 to $500), financial disclosure review, drafting, negotiation, revision, and execution of the final agreement. Under Marital Property Act, s. 41, courts may set aside provisions of a marriage contract when a spouse did not receive independent legal advice and enforcement would be inequitable, making the investment in separate lawyers essential to long-term enforceability.
| Service | Estimated Cost (CAD) |
|---|---|
| Initial consultation (1 hour) | $250 to $500 |
| Simple prenup (few assets, no disputes) | $1,500 to $3,000 per spouse |
| Moderate prenup (multiple assets, negotiation) | $3,000 to $5,000 per spouse |
| Complex prenup (business, high net worth) | $5,000 to $10,000+ per spouse |
| Independent legal advice review only | $500 to $1,500 |
| Financial disclosure preparation | $500 to $2,000 |
| Revisions and amendments | $200 to $500 per round |
New Brunswick does not regulate prenup lawyer fees through a statutory tariff for private retainers. Lawyers set their own rates based on experience, location, and specialization. Moncton, Saint John, and Fredericton firms tend to charge $300 to $500 per hour for senior family law practitioners, while lawyers in smaller communities may charge $250 to $350 per hour. The Law Society of New Brunswick maintains a lawyer search tool at lawsociety-barreau.nb.ca for locating qualified family law practitioners in any judicial district.
Online Prenup Services: Cheap Prenup Options and Their Risks
Online prenup services advertise prices between $99 and $599 for template-based marriage contracts, but these agreements carry significant enforceability risks under New Brunswick law. The Marital Property Act, s. 35 requires that all marriage contracts be in writing, signed by both parties, and witnessed. While an online prenup can meet these formal requirements, the absence of independent legal advice creates a vulnerability under s. 41, which allows courts to disregard contract provisions when a spouse lacked independent counsel and enforcement would be inequitable.
A cheap prenup from an online service may save $2,000 to $4,000 upfront, but the cost of litigating an unenforceable agreement during divorce proceedings can reach $15,000 to $50,000 or more in legal fees. New Brunswick courts apply the two-part test from Miglin v. Miglin (2003 SCC 24): first, whether the agreement was negotiated fairly with proper disclosure and without duress; second, whether the agreement still substantially complies with the objectives of Divorce Act, s. 15.2 at the time of the court application. Online prenup templates rarely account for New Brunswick-specific statutory provisions, property division rules, or the interplay between provincial and federal legislation.
| Factor | Lawyer-Drafted Prenup | Online Prenup |
|---|---|---|
| Cost | $1,500 to $10,000+ per spouse | $99 to $599 total |
| Independent legal advice | Included | Not included |
| Financial disclosure guidance | Included | Self-directed |
| NB-specific statutory compliance | Yes | Often generic |
| Enforceability under s. 41 | Strong | Vulnerable |
| Customization | Full | Template-limited |
| Litigation risk if challenged | Low | High |
| Estimated cost if set aside | N/A | $15,000 to $50,000+ |
Couples considering a cheap prenup alternative should weigh the upfront savings against the long-term risk. A prenuptial agreement cost of $3,000 to $6,000 total is a fraction of the potential litigation expense if an online agreement is challenged during divorce proceedings in the Court of King's Bench, Family Division.
Legal Requirements for a Valid Prenup in New Brunswick
A valid prenuptial agreement in New Brunswick must satisfy three formal requirements under Marital Property Act, s. 35: the contract must be in writing, signed by both parties, and witnessed by at least one witness. New Brunswick does not require notarization, court filing, or registration of marriage contracts. The agreement takes effect upon execution and remains enforceable unless successfully challenged under s. 41 or s. 38.
Beyond the formal requirements, New Brunswick courts evaluate enforceability based on several practical factors drawn from case law and the Miglin v. Miglin (2003 SCC 24) framework. Full financial disclosure by both parties is essential because non-disclosure creates grounds for setting aside the agreement. The agreement must be signed voluntarily, without coercion or undue influence. Courts also consider the timing of execution, with agreements signed weeks or months before the wedding carrying more weight than those signed the night before. Each party obtaining independent legal advice from separate lawyers is the single most important enforceability factor, as the absence of independent counsel triggers the court's discretion under s. 41 to disregard inequitable provisions.
What a Prenup Can and Cannot Cover in New Brunswick
A marriage contract under Marital Property Act, s. 35 allows spouses to agree on their rights and obligations during the marriage, upon separation, upon annulment, upon dissolution, or upon death. New Brunswick prenups commonly address property division, spousal support, debt allocation, inheritance protection, and business interest treatment. However, the Divorce Act, R.S.C. 1985, c. 3 and the Marital Property Act, s. 38 impose important limitations on what a prenup can validly cover.
Parenting arrangements and child support cannot be conclusively determined by a prenuptial agreement. Under Marital Property Act, s. 38(1), courts may disregard any domestic contract provision regarding parenting time or decision-making responsibility where it is in the best interests of the child to do so. Similarly, the Federal Child Support Guidelines established under Divorce Act, s. 15.1 override any prenuptial agreement that attempts to limit or waive child support obligations. Courts retain full jurisdiction over parenting arrangements under Divorce Act, s. 16, regardless of what the parties agreed to before marriage.
Spousal support provisions in a prenup are enforceable but subject to judicial review. Under the Miglin v. Miglin test, a court may override a prenuptial spousal support waiver if the agreement no longer reflects the objectives of Divorce Act, s. 15.2, which include recognizing the economic advantages or disadvantages arising from the marriage and its breakdown.
How to Reduce Prenuptial Agreement Cost in New Brunswick
Couples can reduce the total prenuptial agreement cost by 25% to 40% through preparation and strategic use of legal resources. The most effective cost-reduction strategy is completing a detailed financial inventory before the first lawyer appointment, including lists of all assets, debts, income sources, and expected inheritances. Lawyers spend 30% to 40% of billable hours on financial disclosure review, so arriving with organized documentation saves $500 to $2,000 in legal fees per spouse.
Additional strategies to lower prenup cost in New Brunswick include negotiating key terms with your partner before engaging lawyers, requesting flat-fee quotes instead of hourly billing, using a single drafting lawyer with the other spouse obtaining independent legal advice review only ($500 to $1,500), and scheduling the process 3 to 6 months before the wedding to avoid rush fees. Some New Brunswick family lawyers offer unbundled legal services where they review a client-drafted agreement rather than drafting from scratch, reducing fees to $800 to $2,000 per party.

New Brunswick Marital Property Rules Without a Prenup
Without a prenuptial agreement, New Brunswick divides marital property under the equitable distribution framework established by the Marital Property Act, RSNB 2012, c. 107. Under s. 2, marital property includes all property acquired by either spouse during the marriage, with certain exceptions for gifts, inheritances, and pre-marital assets. The default rule under s. 3 provides for equal division of marital property, but the court may order an unequal division under s. 7 if equal division would be inequitable considering factors such as the length of the marriage, the contribution of each spouse, and the economic circumstances of each spouse at the time of division.
The marital home receives special treatment under the Marital Property Act. Regardless of whose name is on the title, both spouses have equal rights to possession of the marital home during the marriage. Upon separation, the court may order the sale of the home and division of proceeds, transfer of title to one spouse with a compensating payment to the other, or exclusive possession to one spouse for a specified period. A prenuptial agreement allows couples to establish different rules for property division, potentially saving $10,000 to $50,000 or more in litigation costs if the marriage ends.
Spousal Support Considerations in New Brunswick Prenups
New Brunswick courts evaluate spousal support provisions in prenuptial agreements using the Miglin v. Miglin (2003 SCC 24) two-stage test, which examines both the fairness of the negotiation process and the ongoing compliance with the objectives of Divorce Act, s. 15.2. A prenup that completely waives spousal support is more likely to be set aside than one that establishes a reasonable formula, particularly in long marriages where one spouse has sacrificed career opportunities. The Spousal Support Advisory Guidelines, while not binding legislation, provide a framework that New Brunswick courts frequently reference when evaluating whether a prenuptial spousal support provision remains fair.
Under the Advisory Guidelines, spousal support in New Brunswick typically ranges from 1.5% to 2% of the difference in spousal incomes for each year of marriage, paid for a duration equal to 0.5 to 1 year for each year of marriage. For a 10-year marriage with a $50,000 income difference, this produces monthly support of $625 to $833 for 5 to 10 years. A prenuptial agreement that departs significantly from these ranges without justification faces a higher risk of judicial override. Including a review clause that allows the parties to revisit spousal support terms every 5 years or upon a material change in circumstances strengthens enforceability.
The Independent Legal Advice Requirement
Independent legal advice is the single most important factor in prenup enforceability under New Brunswick law. Marital Property Act, s. 41 establishes a two-part test: the court may disregard a domestic contract provision if (1) the challenging spouse entered the contract without receiving legal advice from a lawyer independent of the other spouse's legal advisor, and (2) enforcement would be inequitable in all the circumstances. While s. 41 requires both conditions to be met, the absence of independent legal advice creates a significant vulnerability that opposing counsel will exploit during any challenge.
The cost of independent legal advice review ranges from $500 to $1,500 per spouse in New Brunswick. This fee covers a separate lawyer reviewing the draft agreement, explaining its legal implications, confirming that the client understands what rights they are waiving, and signing a certificate of independent legal advice. This certificate becomes a critical piece of evidence if the agreement is later challenged. Spending $500 to $1,500 on independent legal advice protects an agreement worth potentially hundreds of thousands of dollars in property protection.
