By Antonio G. Jimenez, Esq. | Florida Bar No. 21022 | Covering New Brunswick divorce law
New Brunswick residents cannot directly collect a Canadian ex-spouse's Social Security because Social Security is a United States program. The Canadian equivalent is the Canada Pension Plan (CPP) credit split under CPP Act § 55.1, which equalizes pension credits from any marriage lasting 12 or more consecutive months. If an ex-spouse worked in the United States, divorced New Brunswickers may also claim US Social Security benefits under the 1984 Canada-US Social Security Agreement, provided the marriage lasted at least 10 years.

Social Security vs CPP: What Actually Applies in New Brunswick
United States Social Security benefits are administered by the US Social Security Administration and are not available to Canadian-only workers. In New Brunswick, the functional equivalent is the Canada Pension Plan, which divides contributions made during a marriage under CPP Act § 55.1. Approximately 96 percent of Canadian workers contribute to CPP, and the 2026 maximum retirement benefit is $1,433.00 per month at age 65.
The legal distinction matters because the two systems use different rules. CPP credit splitting is mandatory upon application and cannot be waived by a standard domestic contract in New Brunswick without explicit statutory language. US Social Security ex-spouse benefits, by contrast, require a 10-year marriage, are capped at 50 percent of the worker's primary insurance amount, and are payable only if the claimant is at least 62 years old and currently unmarried. A New Brunswick resident whose former spouse worked in both countries may potentially claim from both systems under separate rules.
The 1984 Canada-US Agreement on Social Security, in force since August 1, 1984, allows individuals to combine credits from both countries to qualify for benefits they otherwise could not receive alone. This is called totalization. Under totalization, a New Brunswicker with only 6 years of US work can still qualify for US Social Security if their combined Canadian and US coverage meets the 40-quarter threshold.
CPP Credit Splitting After Divorce in New Brunswick
CPP credit splitting divides all pensionable earnings recorded during the years the spouses lived together, with each spouse receiving 50 percent of the combined credits. Under CPP Act § 55.1(1)(a), credit splitting is mandatory for divorced formally married couples once Service Canada receives the required documentation. The process is called Division of Unadjusted Pensionable Earnings, or DUPE, and it is free to apply for.
To qualify, the marriage must have lasted at least 12 consecutive months, and the spouses must have lived separately for at least 12 consecutive months before the divorce. The application form is ISP1901, available at Service Canada offices and online. New Brunswick claimants typically submit a certified copy of the divorce judgment along with both parties' Social Insurance Numbers. Processing takes an average of 16 weeks.
A credit split can substantially change retirement income. Example: if Spouse A contributed at the CPP maximum for 20 years during the marriage while Spouse B stayed home, after DUPE each spouse receives credits equal to 10 years of maximum contributions from that period. For a stay-at-home parent who divorces after a 25-year marriage, this split can increase monthly CPP benefits by $400 to $700 at retirement. The split is permanent and cannot be reversed once approved.
New Brunswick is one of only three provinces where spouses cannot contract out of CPP credit splitting through a separation agreement unless the agreement specifically meets the strict requirements in CPP Act § 55.2. Even then, the federal Minister must approve any waiver. Most New Brunswick separation agreements therefore assume the split will proceed.
The Canada-US Social Security Agreement Explained
The Canada-US Agreement on Social Security, signed March 11, 1981, and effective August 1, 1984, allows New Brunswick residents to claim US benefits based on a former spouse's US work history. Under Article V of the Agreement, a divorced spouse who was married for at least 10 years may receive up to 50 percent of the ex-spouse's primary insurance amount, subject to US eligibility rules. The Agreement does not increase benefits but fills coverage gaps.
The US Social Security Administration requires 40 quarters (10 years) of covered US earnings for a worker to be fully insured. If a worker has fewer than 40 quarters, totalization under the Agreement counts CPP contributions toward the 40-quarter requirement. Each Canadian year of CPP contribution generally counts as 4 US quarters for qualification purposes, though the actual benefit amount is calculated only on actual US earnings. This means a former spouse with just 6 years of US work and 15 years of CPP contributions can qualify.
To claim ex-spouse Social Security benefits from New Brunswick, the applicant must be at least 62 years old, currently unmarried, and the ex-spouse must be entitled to Social Security retirement or disability benefits. The divorce must be final. Benefits are paid in US dollars and may be subject to a Windfall Elimination Provision that reduces the amount if the claimant also receives CPP. The 2026 average ex-spouse benefit is approximately $912.00 USD per month.
The 10-Year Marriage Rule for US Social Security Benefits
The ex spouse social security divorce rule requires a marriage lasting at least 10 years before the divorce was finalized for a former spouse to claim derivative benefits on the worker's record. This rule is set by 42 U.S.C. § 402(b) and applies identically to New Brunswick residents claiming through the 1984 Canada-US Agreement. A marriage of 9 years and 11 months does not qualify, regardless of circumstances.
The 10-year clock runs from the date of legal marriage to the date the divorce decree becomes final, which in New Brunswick is 31 days after the divorce judgment is signed under Divorce Act § 12. Separation periods count toward the 10 years as long as the parties remained legally married. Many New Brunswick family lawyers advise clients close to the 10-year mark to delay finalizing the divorce until the threshold is met, because the lifetime value of an ex-spouse benefit can exceed $200,000 USD.
For divorced spouse benefits (as opposed to survivor benefits), the claimant must also have been divorced for at least 2 years before filing if the ex-spouse has not yet started collecting. This 2-year waiting period is waived if the ex-spouse is already receiving benefits. Claiming divorced spouse benefits does not reduce the worker's own benefit or affect a current spouse's entitlement, which is why these benefits are often called silent benefits.
How to Apply for CPP Credit Split in New Brunswick
The CPP credit split application process in New Brunswick takes approximately 16 weeks and requires five documents submitted to Service Canada. There is no fee to apply, and either spouse may initiate the request at any time after the divorce is final. The divorced spouse benefits divorced claimants receive can substantially exceed the cost of the divorce itself when calculated over a 20-year retirement.
Step-by-step application:
- Obtain Form ISP1901 (Application for Division of Unadjusted Pensionable Earnings) from servicecanada.gc.ca or a Service Canada office in Fredericton, Moncton, or Saint John.
- Gather a certified copy of the divorce judgment issued by the Court of King's Bench of New Brunswick, Family Division.
- Provide both spouses' Social Insurance Numbers, dates of birth, and the exact dates of marriage and separation.
- Include proof of the date of cohabitation beginning and ending, typically through a sworn statement or separation agreement.
- Mail the completed package to Service Canada, PO Box 818, Station Main, Winnipeg, MB R3C 2N4, or submit in person at any Service Canada Centre.
Service Canada processes approximately 18,000 DUPE applications annually across Canada. New Brunswick accounts for roughly 2.1 percent of applications, or about 380 per year. Rejection rates are low (under 6 percent) and almost always stem from documentation gaps rather than eligibility issues. Once approved, the split is recorded permanently in both spouses' CPP statements of contributions.
How Divorce Affects Other Retirement Assets in New Brunswick
Under the Marital Property Act § 2, New Brunswick treats private pensions, RRSPs, and workplace retirement plans as marital property subject to equal division upon divorce. The default rule is 50/50 division of the value accrued during the marriage, regardless of whose name is on the account. This is separate from CPP credit splitting and applies to all other retirement assets.
RRSPs can be transferred between spouses on a tax-deferred basis using Canada Revenue Agency Form T2220 (Transfer from an RRSP or RRIF on Breakdown of Marriage). Defined benefit pension plans are divided under the rules of the Pension Benefits Act, R.S.N.B. 1987, c. P-5.1, which typically requires an actuarial valuation and either immediate lump-sum transfer or deferred division at retirement. Locked-in retirement accounts (LIRAs) remain locked after division and can only be accessed under the same conditions as before.
The Marital Property Act defines the valuation date as the date of separation in most cases, meaning post-separation contributions to retirement accounts generally belong to the contributing spouse alone. Short-term marriages (under 5 years) may receive unequal division under Marital Property Act § 7 if the court finds equal division would be inequitable. New Brunswick courts granted unequal division in approximately 8 percent of contested cases in 2024.
Filing for Divorce in New Brunswick: Costs and Requirements
A New Brunswick divorce requires one spouse to have been ordinarily resident in the province for at least 12 months before filing, under Divorce Act § 3(1). The application is filed with the Court of King's Bench, Family Division, using Form 72A (Application for Divorce). The filing fee is approximately $120 CAD as of April 2026. Verify with your local clerk.
Additional costs include a $20 court registry fee for issuing the divorce certificate, a $35 fee for certified copies of the judgment, and approximately $40 for service of documents through a process server. An uncontested divorce in New Brunswick typically costs $1,200 to $2,500 in total legal fees if using a lawyer, while a do-it-yourself uncontested divorce can be completed for under $300. Contested divorces average $15,000 to $45,000 per spouse.
New Brunswick recognizes one ground for divorce under Divorce Act § 8: marriage breakdown. Breakdown is established by 12 months of separation, adultery, or physical/mental cruelty. Over 94 percent of New Brunswick divorces proceed on the 12-month separation ground. Parenting arrangements, including decision-making responsibility and parenting time, are governed by the 2021 amendments to the Divorce Act, which replaced the terms custody and access throughout federal family law.
After the judgment is granted, there is a mandatory 31-day waiting period before the divorce becomes final and a certificate of divorce can be issued. This waiting period exists to allow appeals. Only after the certificate issues can either party remarry or apply for a CPP credit split. The average New Brunswick uncontested divorce takes 4 to 6 months from filing to certificate.
