A prenuptial agreement (called a "marriage contract" in Yukon) must include specific clauses to be legally enforceable under Yukon's Family Property and Support Act, RSY 2002, c. 83. Under Section 61(1), the agreement must be in writing, signed by both parties, and witnessed by an independent third person. Approximately 50% of first marriages in Canada experience significant financial disagreements, and a properly drafted prenuptial agreement can prevent costly litigation that averages $15,000-$50,000 in contested divorce proceedings.
This guide covers every essential clause and requirement for what to include in a prenup in Yukon, from property division provisions to spousal support terms to financial disclosure requirements.

What Is a Marriage Contract in Yukon?
A marriage contract in Yukon is a legally binding agreement between two people entered into before their marriage, or during their marriage while cohabiting, that outlines their respective rights and obligations regarding property division, support obligations, and other financial matters upon marriage breakdown. Under the Family Property and Support Act, this type of domestic contract allows couples to contract out of the default 50/50 property division rules that would otherwise apply under Section 6 of the Act.
The Act defines "domestic contract" to include marriage contracts, separation agreements, and cohabitation agreements. Importantly, if parties enter into a cohabitation agreement and subsequently marry, Section 60(2) deems that agreement to become a marriage contract automatically, unless the agreement states otherwise.
Essential Clauses to Include in a Yukon Prenuptial Agreement
1. Complete Asset and Property Disclosure Schedule
Full financial disclosure forms the foundation of every enforceable Yukon prenuptial agreement, and failure to disclose material assets can render the entire agreement unenforceable in court. Yukon courts have repeatedly held that both parties must provide complete lists of all assets, debts, income sources, and financial interests at the time of signing. The disclosure schedule should itemize real estate holdings with current market values, bank accounts and investments, business interests with valuations, vehicles and valuable personal property, retirement accounts (RRSPs, pension plans), and all outstanding debts and liabilities.
A typical disclosure schedule should include:
- Real property addresses, legal descriptions, and fair market values
- Bank account numbers and current balances
- Investment portfolio statements
- Business ownership percentages and valuations
- Vehicle make, model, year, and value
- Outstanding mortgage balances, credit card debts, and loans
- Pension plan statements and RRSP values
2. Pre-Marital Property Protection Clauses
Yukon's default property division rules under Section 6 of the Family Property and Support Act grant each spouse equal entitlement to 50% of family assets upon marriage breakdown, regardless of who purchased the property or whose name appears on title. A prenuptial agreement can specify that pre-marital assets remain the separate property of the spouse who brought them into the marriage. Without this clause, property owned before marriage could become subject to division if it becomes "ordinarily used or enjoyed by the family" during the marriage.
Effective pre-marital property clauses should:
- List each asset with acquisition date and value at marriage
- Specify whether appreciation during marriage is shared or separate
- Address how commingled assets will be treated
- Define procedures for tracing original contributions
3. Business Interest Protection Provisions
Business owners should include comprehensive provisions protecting their ownership interests, which typically represent 60-80% of an entrepreneur's net worth. The prenuptial agreement should clearly state that one spouse's business remains separate property and define how any increase in value during the marriage will be treated. Under Yukon law, business assets can become family assets subject to division if they are used for family purposes, making explicit protection essential.
Key business protection elements include:
- Clear statement of business ownership and percentage
- Valuation methodology for potential future disputes
- Treatment of business income used for family expenses
- Restrictions on the other spouse's involvement in business decisions
- Buy-out provisions if division becomes necessary
4. Spousal Support Terms and Conditions
Yukon prenuptial agreements can include spousal support provisions, but courts retain discretion to override terms that would cause undue hardship or injustice under Section 43 of the Family Property and Support Act. Approximately 70% of contested divorce cases involve spousal support disputes, making clear prenuptial terms valuable. However, spousal support waivers that leave one spouse destitute or dependent on public assistance are unlikely to be enforced.
Enforceable spousal support clauses typically address:
- Whether support is waived, limited, or guaranteed
- Duration and amount formulas (e.g., $X per year of marriage)
- Circumstances triggering modification (job loss, disability, caregiving)
- Review mechanisms for long marriages (10+ years)
- Acknowledgment that unconscionable terms may be set aside
5. Property Division Framework
Without a prenuptial agreement, Section 6 of the Family Property and Support Act entitles each spouse to an equal 50% share of family assets. A marriage contract allows couples to agree on different division terms, such as keeping certain categories of property separate or agreeing to a percentage split other than 50/50. The agreement should specify exactly how various asset categories will be divided upon marriage breakdown.
| Asset Category | Default (No Prenup) | Common Prenup Terms |
|---|---|---|
| Family Home | 50/50 division | Ownership to purchaser, equity split varies |
| Pre-marital Assets | Included in family assets | Remain with original owner |
| Inheritances | May be included* | Protected as separate property |
| Gifts | May be included* | Protected as separate property |
| Pension/RRSP | 50/50 division | Various formulas possible |
| Business Interests | Subject to division | Protected as separate property |
*Under Section 13(e), gifts and inheritances are factors courts consider when determining if equal division would be inequitable.
6. Debt Responsibility Allocation
Clear debt allocation clauses protect each spouse from responsibility for the other's pre-existing or separate debts. The prenuptial agreement should list all current debts each party is bringing into the marriage and specify who remains responsible for those obligations. For debts incurred during marriage, the agreement can establish whether they are joint responsibilities or assigned to the spouse who incurred them.
Debt clauses should address:
- Pre-marital debts (student loans, credit cards, mortgages)
- Debts incurred during marriage (joint vs. individual)
- Business debts and liabilities
- Indemnification provisions protecting each spouse
- Credit card and line of credit responsibility
7. Inheritance and Gift Protection
Inheritances and gifts received during marriage can become family assets subject to division under Yukon's default rules, particularly if deposited into joint accounts or used to improve joint property. A prenuptial agreement can establish that inheritances and gifts remain the separate property of the receiving spouse, protecting family wealth passed down through generations.
Protection clauses should specify:
- Inheritances remain separate property regardless of timing
- Gifts from family members remain separate property
- Procedures for keeping inherited/gifted assets separate
- Treatment of income generated by separate property
- Appreciation on separate property during marriage
8. Matrimonial Home Provisions
The family home receives special treatment under Canadian family law, and certain rights cannot be waived in a prenuptial agreement. While ownership of the matrimonial home can be addressed, possession rights and rights relating to sale or encumbrance typically cannot be waived. In Yukon, under Part 2 of the Family Property and Support Act, provisions limiting a spouse's rights to the family home are void.
Valid matrimonial home clauses can address:
- Which spouse owns the property
- How equity will be divided upon separation
- Buyout procedures and timelines
- Responsibility for mortgage, taxes, and maintenance
Clauses that courts will NOT enforce:
- Removing a spouse's right to occupy the home
- Allowing sale without spouse's consent
- Waiving right to notice of sale or mortgage
9. Life Insurance and Beneficiary Designations
Prenuptial agreements often require spouses to maintain life insurance policies with each other as beneficiaries, particularly when one spouse is waiving property rights or support claims. These provisions ensure financial protection for the surviving spouse despite the prenuptial waivers. Typical requirements include minimum coverage amounts ($250,000-$1,000,000) that may decrease over time.
Life insurance provisions should include:
- Minimum coverage amounts required
- Named beneficiary requirements
- Proof of coverage exchange schedule
- Consequences of policy lapse or reduction
- Adjustment mechanisms based on dependents or assets
10. Sunset and Review Clauses
Many Yukon prenuptial agreements include sunset clauses that cause certain provisions to expire after a specified marriage duration (commonly 10-15 years) or trigger mandatory review periods. These provisions acknowledge that circumstances change over long marriages and can make prenuptial agreements more fair and thus more likely to be enforced.
Common sunset provisions include:
- Full expiration after X years of marriage
- Partial expiration of specific clauses
- Mandatory review and renegotiation triggers
- Modification procedures requiring written amendment
- Birth of children as a review trigger
Formal Requirements for a Valid Yukon Prenuptial Agreement
Yukon's Family Property and Support Act, Section 61(1) establishes mandatory formal requirements that must be satisfied for a domestic contract to affect rights under the Act. A prenuptial agreement that fails to meet these requirements will not be enforceable.
Mandatory Requirements Under Section 61
- Written Document: The agreement must be in writing; oral agreements are unenforceable
- Both Parties Sign: Each party must personally sign the agreement
- Independent Witness: An independent third person must witness both signatures
- Voluntary Execution: Both parties must enter the agreement freely without coercion
- Full Disclosure: Material financial information must be exchanged
Strongly Recommended (Though Not Legally Required)
- Independent Legal Advice: Each party should consult their own lawyer
- Certificates of Independent Legal Advice: Lawyers certify they explained the agreement
- Reasonable Time to Review: Signing should not occur under time pressure
- Fairness at Execution and Enforcement: Unconscionable terms may be set aside
Grounds for Setting Aside a Yukon Prenuptial Agreement
Under Section 43 of the Family Property and Support Act, courts have authority to set aside domestic contracts in specific circumstances. Understanding these grounds helps parties create agreements more likely to withstand legal challenge.
Statutory Grounds for Setting Aside
| Ground | Description | Prevention Strategy |
|---|---|---|
| Lack of Disclosure | Material assets or debts not disclosed | Complete financial schedules with documentation |
| Lack of Understanding | Party did not understand nature/consequences | Independent legal advice certificates |
| Coercion/Duress | Agreement obtained through pressure | Sign well before wedding (60+ days recommended) |
| Unconscionability | Terms grossly unfair at signing or enforcement | Balanced terms, sunset clauses |
| Failure of Formalities | Not written, signed, or witnessed properly | Follow Section 61 requirements exactly |
Judicial Discretion to Override
Even when a prenuptial agreement meets all formal requirements, courts retain discretion to decline enforcement of specific provisions in the interest of fairness. Under the Act, if a court is satisfied that a person secured agreement through undue influence, it may decline to give effect to those provisions. Spousal support waivers that would leave one spouse destitute are particularly vulnerable to judicial override.
What Cannot Be Included in a Yukon Prenuptial Agreement
Certain matters are outside the scope of what to include in a prenup in Yukon because they are either unenforceable or void under the law.
Unenforceable Provisions
-
Parenting Arrangements for Children: Decisions about parenting time and decision-making responsibility must be made according to the best interests of the child at the time of separation, not predetermined in a prenuptial agreement
-
Child Support Waivers: Child support is the right of the child, not the parent, and cannot be waived or limited by parental agreement
-
Family Home Possession Rights: Under Part 2 of the Family Property and Support Act, provisions limiting a spouse's rights under that Part (relating to the family home) are void
-
Lifestyle Clauses: Provisions penalizing infidelity, requiring specific behaviors, or addressing intimate matters are generally unenforceable
-
Illegal Terms: Any provision requiring illegal conduct is void
Timing Considerations for Yukon Prenuptial Agreements
The timing of when a prenuptial agreement is signed significantly impacts its enforceability. Agreements signed under time pressure shortly before a wedding are more vulnerable to challenge on grounds of duress or lack of informed consent.
Recommended Timeline
| Timeframe | Action |
|---|---|
| 6+ months before wedding | Begin initial discussions |
| 4-5 months before | Each party retains independent lawyer |
| 3-4 months before | Exchange financial disclosures |
| 2-3 months before | Draft agreement and negotiate terms |
| 60+ days before | Both parties sign with witness |
| After signing | Store original safely, provide copies to lawyers |
Cost of Prenuptial Agreements in Yukon
The cost of preparing a prenuptial agreement in Yukon varies based on complexity and whether both parties use lawyers. Legal fees in Yukon typically range from $300-$500 per hour for family law practitioners.
Typical Cost Ranges
| Complexity Level | Estimated Cost Range |
|---|---|
| Simple (minimal assets, standard terms) | $1,500 - $3,000 total |
| Moderate (some assets, customized terms) | $3,000 - $6,000 total |
| Complex (business interests, significant assets) | $6,000 - $15,000+ total |
These costs include legal fees for both parties obtaining independent legal advice. Attempting to save money by sharing a lawyer or foregoing legal advice increases the risk of the agreement being set aside later, potentially costing far more in litigation expenses.
Common Mistakes to Avoid in Yukon Prenuptial Agreements
Approximately 30% of prenuptial agreements face legal challenges during divorce proceedings, often due to preventable drafting errors or procedural failures.
Critical Errors That Undermine Enforceability
- Incomplete Financial Disclosure: Omitting assets or undervaluing property
- No Independent Legal Advice: Both parties using one lawyer or no lawyer
- Signing Too Close to Wedding: Creating appearance of pressure or duress
- Unconscionable Terms: One-sided agreements that shock the conscience
- Missing Witness Signature: Failing to have an independent witness
- Attempting to Waive Parenting Rights: Including child-related provisions
- No Sunset or Review Provisions: Failing to account for changing circumstances
- Oral Side Agreements: Making verbal promises that contradict written terms
Frequently Asked Questions About Yukon Prenuptial Agreements
Is a prenuptial agreement legally binding in Yukon?
A prenuptial agreement is legally binding in Yukon when it complies with Section 61(1) of the Family Property and Support Act, which requires the agreement be in writing, signed by both parties, and witnessed by an independent third person. Courts will generally enforce properly executed agreements unless grounds exist to set them aside under Section 43, such as lack of disclosure, unconscionability, or coercion. Approximately 85% of properly drafted prenuptial agreements are upheld when challenged.
Can a prenup waive spousal support in Yukon?
Yukon prenuptial agreements can include spousal support waivers, but courts retain discretion to override these provisions if enforcement would cause undue hardship or injustice. A complete spousal support waiver signed by someone with significant earning capacity is more likely to be enforced than one signed by a spouse who gave up career opportunities for the marriage. Courts consider circumstances at both signing and enforcement when evaluating support waivers.
Do both parties need lawyers for a Yukon prenuptial agreement?
While Section 61 does not legally mandate independent legal advice, having each party consult their own lawyer significantly strengthens enforceability. When one party later claims they did not understand the agreement, certificates of independent legal advice provide powerful evidence that both parties entered the agreement with full knowledge of its implications. Legal fees of $1,500-$3,000 per party are a worthwhile investment compared to $15,000-$50,000 in potential litigation costs.
How far in advance should we sign a prenup before our wedding?
Signing a prenuptial agreement at least 60 days before the wedding date is strongly recommended, with 90+ days being preferable for complex agreements. Agreements signed days or weeks before a wedding are vulnerable to challenge on grounds that time pressure constituted duress. One Yukon court observed that presenting an agreement the night before a wedding, with deposits already paid and guests arriving, creates inherent coercion regardless of the other party's subjective feelings.
Can a prenup protect my business in Yukon?
A properly drafted prenuptial agreement can protect business ownership interests from division as family property, which is particularly important since business assets can represent 60-80% of an entrepreneur's net worth. The agreement should clearly identify the business, establish its pre-marital value, and specify how growth during marriage will be treated. Without protection, a business could become subject to 50/50 division under Section 6 of the Family Property and Support Act if it is used for family purposes.
What happens to a Yukon prenup if we have children?
The birth of children does not automatically invalidate a Yukon prenuptial agreement, but child-related provisions in the agreement are unenforceable. Parenting arrangements and child support must be determined at the time of separation based on the best interests of the child, not according to prenuptial terms. Many agreements include sunset clauses that trigger review or modification upon birth of children, acknowledging that family circumstances have fundamentally changed.
Can we modify our prenup after marriage in Yukon?
Yes, married couples can modify their prenuptial agreement at any time by executing an amending agreement that meets the same formal requirements as the original under Section 61. Both parties must sign the amendment in writing with an independent witness. Amendments commonly occur when circumstances change significantly, such as inheritance receipt, business sale, career changes, or the birth of children. The amended terms supersede the original provisions on the same subjects.
Does a Yukon prenup cover common-law relationships?
A cohabitation agreement serves the same function for common-law couples as a prenuptial agreement does for married couples, and if common-law partners later marry, their cohabitation agreement automatically becomes a marriage contract under Section 60(2) unless the agreement states otherwise. Common-law couples in Yukon face different default property rules than married spouses, making cohabitation agreements especially important since common-law partners do not have automatic equal property division rights.
How long does a Yukon prenup last?
A Yukon prenuptial agreement remains in effect until the marriage ends through divorce or death, unless the agreement contains sunset clauses specifying expiration or modification triggers. Many agreements include provisions that expire after 10-15 years of marriage or that require renegotiation when certain events occur (childbirth, significant inheritance, retirement). Without sunset provisions, the original terms continue to govern indefinitely.
What makes a prenup unconscionable in Yukon?
A prenuptial agreement is unconscionable when its terms are so grossly unfair that they "shock the conscience" of the court, either at the time of signing or at the time of enforcement. Courts consider factors including the disparity in bargaining power, whether one party was vulnerable or unsophisticated, whether independent legal advice was obtained, and whether the terms leave one spouse destitute while the other retains substantial wealth. Agreements that waive all rights for one party while preserving all rights for the other are likely to be deemed unconscionable.
Conclusion: Creating an Enforceable Yukon Prenuptial Agreement
Understanding what to include in a prenup in Yukon requires attention to both substantive terms and procedural formalities. The Family Property and Support Act provides a clear framework: written agreement, both parties signed, independent witness, full financial disclosure, and fair terms. Couples who invest in proper legal advice and allow adequate time for negotiation create agreements that protect their interests while withstanding potential legal challenges.
The prenup clauses covered in this prenuptial agreement checklist represent current best practices for Yukon marriage contracts: comprehensive asset disclosure, clear property division terms, reasonable spousal support provisions, business protection, debt allocation, and appropriate sunset clauses. By addressing what can a prenup cover thoroughly and avoiding unenforceable provisions, Yukon couples can enter marriage with financial clarity and protection.
