Divorce After 20+ Years of Marriage in New Brunswick: Complete 2026 Guide

Divorce after 20 years of marriage in New Brunswick triggers special provisions under Canada's Spousal Support Advisory Guidelines (SSAG) that can result in indefinite support obligations. Under the federal Divorce Act, R.S.C. 1985, c. 3, s. 15.2, spouses in marriages lasting 20 years or more qualify for support durations ranging from 10 to 20 years at minimum, with many cases resulting in support without a specified end date. The filing fee for divorce in New Brunswick is $110, and the Court of King's Bench, Family Division processes uncontested cases in 4 to 8 weeks. Property division follows the Marital Property Act, RSNB 2012, c. 107, which mandates equal 50/50 division of marital assets accumulated during the relationship.

Key Facts: Long-Marriage Divorce in New Brunswick

Understanding Why Long Marriages Receive Special Treatment

Divorce after 20 years of marriage in New Brunswick receives distinct legal treatment because Canadian courts recognize that long-term spouses experience profound economic interdependence that cannot be easily unwound. Under the Spousal Support Advisory Guidelines developed by the federal Department of Justice, marriages of 20 years or longer generate support amounts calculated at 1.5% to 2% of the gross income difference per year of marriage, reaching the maximum formula range of 37.5% to 50% of the income differential. For a 25-year marriage where one spouse earns $120,000 and the other earns $40,000, the annual spousal support range would be $30,000 to $40,000 (37.5% to 50% of the $80,000 difference). This calculation reflects the Supreme Court of Canada's landmark decision in Moge v. Moge, which established that spousal support must compensate for economic sacrifices made during the marriage.

The rationale for these enhanced protections stems from the recognition that spouses in long marriages often make career sacrifices that become irreversible over time. A spouse who left the workforce at age 30 to raise children cannot realistically re-enter their profession at age 55 with the same earning capacity. New Brunswick courts applying the Divorce Act, R.S.C. 1985, c. 3, s. 15.2(6) consider four objectives: recognizing economic advantages and disadvantages from the marriage, apportioning child-care consequences, relieving economic hardship, and promoting self-sufficiency within a reasonable period. In traditional long marriages, self-sufficiency is often an unattainable objective, making ongoing support necessary to maintain a reasonable standard of living.

The Rule of 65: Indefinite Support Explained

The Rule of 65 provides that spousal support may continue indefinitely when the recipient spouse's age at separation plus the years of marriage equals or exceeds 65. Under this formula, a spouse who is 50 years old at separation after a 15-year marriage qualifies for indefinite support because 50 + 15 = 65. For couples divorcing after 20 or more years of marriage, the Rule of 65 applies automatically regardless of age, meaning a 45-year-old spouse separating after a 20-year marriage qualifies for indefinite support even though 45 + 20 = 65. The term "indefinite" under Canadian law means support without a specified end date at the time the order is made, not necessarily permanent support. Courts retain jurisdiction to review and modify indefinite support orders if circumstances change materially, such as retirement, remarriage, or significant income changes.

The Rule of 65 has one important exception: marriages lasting fewer than five years do not qualify even if the arithmetic formula is satisfied. A 62-year-old spouse separating after a 3-year marriage would reach the threshold (62 + 3 = 65) but would not qualify for indefinite support because the marriage was too short. For divorces after 20 years in New Brunswick, this exception is irrelevant since all such marriages far exceed the five-year minimum. The practical effect of the Rule of 65 is that spouses in long marriages should expect support obligations to continue until retirement, death, or another significant life event triggers a variation application under the Divorce Act, R.S.C. 1985, c. 3, s. 17.

Spousal Support Calculation for Long Marriages

Spousal support amounts in New Brunswick for marriages without dependent children follow the Without Child Support Formula under the SSAG. The formula calculates support as 1.5% to 2% of the gross income difference between spouses for each year of marriage, capped at 50% of the difference. For a 20-year marriage, support ranges from 30% (20 years × 1.5%) to 40% (20 years × 2%) of the gross income differential. For a 25-year marriage, the range increases to 37.5% to 50% of the income difference. The gross income ceiling for SSAG calculations is $350,000 annually, and no support is typically ordered when the payor earns below $20,000 per year.

When dependent children exist, New Brunswick courts apply the With Child Support Formula, which uses net disposable income rather than gross income. This formula allocates between 40% and 46% of the combined net disposable incomes to the lower-income spouse. The formula accounts for the payor's child support obligations, the recipient's child-related expenses, and available government benefits like the Canada Child Benefit. Because child support takes priority over spousal support under Canadian law, the With Child Support Formula often produces lower monthly spousal support amounts than the Without Child Support Formula, but the total family support (child plus spousal) typically exceeds what spousal support alone would be.

Property Division in Long-Marriage Divorces

New Brunswick's Marital Property Act, RSNB 2012, c. 107, s. 2 mandates equal division of marital property, establishing that each spouse is entitled to 50% of assets acquired during the marriage. Section 2 explicitly recognizes that child care, household management, and financial provision are joint responsibilities of equal importance. Unlike equitable distribution provinces where judges have discretion to divide property 60/40 or otherwise, New Brunswick follows a strict equal division model. Marital property includes the matrimonial home, vehicles, investments, pensions, household goods, and recreational assets used by the family during cohabitation.

Business assets receive special treatment under the Marital Property Act. Property owned by one spouse and used principally in carrying on a business is excluded from automatic equal division. This exclusion protects entrepreneurs who built businesses before or during the marriage, though the increase in business value during the marriage may still be divisible. The other spouse may have a constructive trust claim if they contributed to the business through unpaid labor or by freeing the business-owner spouse from domestic responsibilities. In long marriages of 20+ years, courts are more likely to find that both spouses contributed to wealth accumulation regardless of whose name appears on title documents.

Property division applications must be filed within 60 days of the divorce judgment under the Marital Property Act. This deadline is strict, and missing it can forfeit rights to claim property division through the court process. Spouses negotiating separation agreements should address property division before the divorce is finalized to avoid this limitation period. Unlike spousal support orders, which can be varied if circumstances change, property division is final once ordered by the court.

Pension Division and CPP Credit Splitting

Pension division in divorces after 20 years of marriage often involves substantial assets accumulated over decades of employment. Canada Pension Plan (CPP) credits earned during the marriage can be equally split between spouses through the federal credit splitting process. Either spouse can apply to Service Canada using Form ISP-1901 after divorce or separation. The split is mandatory in New Brunswick because the province has not enacted legislation allowing couples to opt out of CPP credit splitting, unlike Alberta, British Columbia, and Saskatchewan. Credits accumulated during the marriage are divided 50/50, and the division is permanent once processed.

Employer-sponsored pension plans governed by New Brunswick's Pension Benefits Act require a different process. The Act provides that separated common-law partners who lived together for at least two uninterrupted years may be entitled to a share of pension credits. For married spouses, there is no minimum cohabitation period. Pension values are typically determined by actuarial reports, which calculate the present value of future pension benefits. For defined benefit pensions common among government employees, teachers, and healthcare workers, actuarial reports cost between $300 and $1,500. The pension value is then included in the marital property calculation and divided according to the Marital Property Act's equal division principle.

Filing for Divorce in New Brunswick After 20+ Years

Filing for divorce in New Brunswick requires that at least one spouse has ordinarily resided in the province for one year immediately before commencing proceedings under the Divorce Act, R.S.C. 1985, c. 3, s. 3(1). The filing fee is $110, comprising $100 for the petition and $10 for the Clearance Certificate from the Central Registry of Divorce Proceedings. The Certificate of Divorce costs an additional $7 after the judgment becomes effective. Filing occurs at the Court of King's Bench, Family Division, with offices in Bathurst, Campbellton, Edmundston, Fredericton, Miramichi, Moncton, Saint John, and Woodstock.

For joint applications where both spouses agree on all terms, Form 72B (Joint Petition for Divorce) is used. For contested divorces or where one spouse is initiating the process, Form 72A (Petition for Divorce) is filed. After filing, the respondent has 30 days to respond if served within Canada, or 60 days if served outside Canada. In uncontested cases, the judge reviews the file without a hearing and issues the divorce judgment within 4 to 8 weeks of filing. The divorce judgment becomes effective 31 days later under the Divorce Act, R.S.C. 1985, c. 3, s. 12(1), during which either party may appeal.

Cost Breakdown: Uncontested vs. Contested Divorce

Divorce costs in New Brunswick vary dramatically based on whether the matter is contested. Uncontested divorces typically cost between $1,650 and $3,000 CAD, including court fees, legal document preparation, and basic legal advice. New Brunswick divorce attorneys charge a median hourly rate of $350 CAD. For uncontested divorces without parenting or support issues, some firms offer flat fees starting at approximately $1,200 plus HST. Uncontested cases involving parenting or support terms typically cost around $1,750 as a flat fee.

Contested divorces after 20 years of marriage frequently cost between $16,500 and $50,000 or more, particularly when pension valuations, business appraisals, or extensive parenting disputes are involved. Hidden costs include process server fees ($70 to $250), property appraisals for real estate ($300 to $2,000), business valuations ($5,000 to $20,000), actuarial reports for pension division ($300 to $1,500), and court transcript fees if motions are required. Fee waivers are available for recipients of Family Income Security Act benefits or legal aid, and may be granted when a solicitor certifies that remuneration for legal services will not be paid and payment of the fee would impose financial hardship.

As of March 2026, verify all fees with the Court of King's Bench clerk's office.

Parenting Arrangements in Long-Marriage Divorces

Divorce after 20+ years of marriage often involves adult or nearly adult children, but when minor children are present, New Brunswick courts apply the parenting provisions of the Divorce Act, R.S.C. 1985, c. 3, s. 16.1 as amended in 2021. The Act uses the terminology "parenting arrangements" rather than custody, "parenting time" rather than visitation, and "decision-making responsibility" rather than legal custody. These terminology changes reflect modern understanding that both parents typically remain actively involved in children's lives after separation.

The primary consideration in all parenting decisions is the best interests of the child under the Divorce Act, R.S.C. 1985, c. 3, s. 16(1). Factors include each parent's willingness to support the child's relationship with the other parent, the child's views and preferences considering their age and maturity, the child's cultural and linguistic heritage, and any history of family violence. In long marriages, courts often find that established parenting patterns during the marriage provide strong evidence of each parent's parenting capacity. A parent who was the primary caregiver for 20 years will typically continue in a similar role post-divorce unless circumstances warrant a different arrangement.

Three Types of Spousal Support Entitlement

Canadian law recognizes three distinct bases for spousal support entitlement: compensatory, non-compensatory, and contractual. Understanding which applies to your situation affects both the amount and duration of support. The Supreme Court of Canada established these categories in Moge v. Moge and Bracklow v. Bracklow, decisions that remain the foundation of Canadian spousal support law.

Compensatory support addresses economic sacrifices made during the marriage. When one spouse reduced their career involvement to manage the household or raise children while the other advanced professionally, compensatory support attempts to remedy that imbalance. In 20+ year marriages where one spouse stayed home to raise children and manage the household, compensatory claims are typically strong. The economic disadvantage from a 20-year career gap is usually permanent and substantial.

Non-compensatory support addresses economic hardship and interdependence that develops over time. Even when both spouses worked throughout the marriage, a 20-year relationship creates mutual dependency. The lower-income spouse becomes accustomed to a particular standard of living that they cannot maintain independently. Non-compensatory support seeks to alleviate this hardship without requiring proof of specific career sacrifices. In long marriages, non-compensatory claims often overlap with compensatory claims, strengthening the overall entitlement.

Contractual support arises from separation agreements or marriage contracts. Spouses who negotiated spousal support terms in a written agreement are bound by those terms unless the agreement is set aside by a court. The Supreme Court in Miglin v. Miglin held that courts should respect contractual arrangements but may intervene if the agreement is not in substantial compliance with the Divorce Act's objectives. In long marriages, agreements made early in the relationship may be reviewed if circumstances have changed substantially.
