Separation Agreement in New Brunswick: What It Must Include to Hold Up in Court

A separation agreement is the fastest way to settle property, debts, and support without a trial in New Brunswick. But a poorly drafted one can be thrown out by the Court of King's Bench — and there is no second chance if you miss the strict 60-day property-division deadline after your divorce becomes final.

Here is exactly what your agreement needs to address and the legal requirements that make it enforceable.

How Property Division Works Without an Agreement

New Brunswick follows strict equal division under the Marital Property Act (RSNB 2012, c. 107). Every family asset — the matrimonial home, bank accounts, vehicles, RRSPs, pensions, and household goods — is split 50/50 by default, regardless of whose name is on the title.

A separation agreement lets spouses override that default. You can agree to an unequal split, allow one person to keep the home, or structure pension transfers differently — as long as both sides sign voluntarily with full knowledge of what they are giving up.

Without a written agreement, the court applies the statutory 50/50 presumption and divides everything for you. That process takes 6 to 24 months and costs $11,000 to $43,000 or more in legal fees for contested cases.

Three Requirements the Court Checks Before Enforcing Your Agreement

Under Section 43 of the Marital Property Act, the Court of King's Bench can set aside a domestic contract if any of these conditions are missing:

Full Financial Disclosure. Both spouses must exchange complete, sworn financial information before signing. In practice, this means each side should complete a Form 72J (Financial Statement) with three years of CRA Notices of Assessment, current pay stubs, bank statements, pension valuations, and property appraisals.

No Duress or Coercion. The agreement must be signed voluntarily. If one spouse pressured the other — threats of withholding access to children, ultimatums about the matrimonial home, or signing under extreme emotional distress — the court can void it entirely.

Independent Legal Advice (ILA). Each spouse must get separate legal advice from their own lawyer. The lawyer reviews the agreement, explains what rights the client is waiving, and signs a certificate confirming they provided this advice. Without ILA certificates, the agreement is vulnerable to challenge.

What a New Brunswick Separation Agreement Must Cover

A comprehensive separation agreement for financial division addresses these categories:

Marital Property Inventory. List every family asset with its fair market value as of the separation date — the house, vehicles, bank accounts, RRSPs, TFSAs, pensions, and household contents. New Brunswick uses the separation date as the valuation date, so all assets and debts are frozen at that point.

The Matrimonial Home. Specify who keeps it (with a buyout of the other's 50% equity), whether it will be sold, or if both parties will maintain joint ownership temporarily. If one spouse is buying out the other, include a refinancing deadline so both names come off the mortgage.

Pension Division. Address CPP credit splitting (mandatory in New Brunswick — you cannot waive it), provincial pensions administered by Vestcor, and any federal pensions. For Vestcor pensions, the non-member spouse receives up to 50% of the marital portion transferred to a Locked-in Retirement Account (LIRA).

Debt Allocation. List every joint and individual debt incurred during the marriage. Under the Marital Property Act, marital debts are shared equally. Your agreement should specify who pays which debt and include a hold-harmless clause — because creditors are not bound by your agreement and can still pursue either spouse on a joint account.

Spousal Support. If one spouse earns significantly more, address whether periodic monthly support (tax-deductible for the payer) or a lump-sum buyout (non-deductible, non-taxable) makes more sense. Courts apply the federal Spousal Support Advisory Guidelines (SSAG) when assessing adequacy.

Beneficiary Updates. A divorce does not automatically revoke beneficiary designations under New Brunswick's Insurance Act. Your agreement should require both parties to update beneficiaries on life insurance, RRSPs, TFSAs, and pensions within a set number of days after signing.

The 60-Day Deadline You Cannot Miss

Under Section 3(2) of the Marital Property Act, you must file an application for property division within 60 days after your divorce judgment takes effect. If you have not resolved everything through a separation agreement before that window closes, and you have not filed a separate court application, you permanently lose the right to claim equal division.

This is why most family lawyers in New Brunswick recommend finalizing and signing the separation agreement before or alongside filing the divorce petition — not after.

When a Separation Agreement Alone Is Not Enough

A separation agreement handles property and support, but it does not grant a divorce. You still need to file a Petition for Divorce (Form 72A for sole, Form 72B for joint) with the Family Division of the Court of King's Bench. Filing costs $110 total — $100 for the petition and $10 for the Ottawa Clearance Certificate.

For complex situations — business ownership, multiple properties, suspected hidden assets, or significant pension accumulations — working with both a mediator and independent lawyers protects both sides. Private mediation in New Brunswick runs $150 to $300 per hour, but a mediated agreement typically costs $2,000 to $4,000 total, far less than litigation.
