A prenup business owner Yukon strategy works by excluding your company from the default 50/50 split of family assets under the Family Property and Support Act § 6. A valid marriage contract costs $1,500 to $5,000 to draft, requires written form, signatures, witnessing, full financial disclosure, and independent legal advice for each spouse.
Yukon is one of Canada's few jurisdictions where common-law partners face automatic property division after two years of cohabitation, so an entrepreneurial prenup or cohabitation agreement protects your business whether you marry or simply live together. Without one, the increase in your business value during the relationship is presumptively divisible.

How Yukon Divides a Business Without a Prenup
Without a marriage contract, Yukon law presumes equal division of family assets when a marriage breaks down. Under Family Property and Support Act § 6, each spouse is entitled to an equal share of family assets regardless of whose name holds title. For a business owner, this means the increase in your company's value during the marriage is presumptively split 50/50, even if your spouse never worked in the business.
The Act defines family assets as property ordinarily used or enjoyed by both spouses or their children for shelter, transportation, household, educational, recreational, social, or aesthetic purposes. A pure business interest may fall outside this definition, but Yukon courts can still capture business growth through equitable adjustment provisions or by characterizing assets as family property. The court may depart from equal division under Family Property and Support Act § 13 and § 14, weighing factors like marriage duration and pre-marriage acquisition. Relying on judicial discretion is far riskier than a written agreement, which is precisely why an LLC prenup or corporate marriage contract matters for entrepreneurs.
What a Marriage Contract Can Exclude
A Yukon marriage contract can exclude your business from family assets entirely, removing it from the default 50/50 division. The statutory mechanism is the definition of family assets, which expressly excludes property that spouses agree by marriage contract is not to be included. This is the single most reliable way to protect business prenup interests in the territory, far stronger than hoping a court exercises discretion under sections 13 and 14.
Under the Act, a marriage contract is an agreement between two persons entered into before marriage, or during marriage while cohabiting, addressing their respective rights and obligations including ownership in or division of property. A well-drafted entrepreneurial prenup typically excludes the business entity itself, retained earnings, future appreciation in value, shares or partnership interests, and intellectual property. It can also waive or cap spousal support claims tied to business income. The agreement controls because Family Property and Support Act § 2 gives valid domestic contracts priority over the statutory default rules, so long as the agreement is valid and binding.
Requirements for a Valid Business Prenup in Yukon
For a Yukon marriage contract to bind, it must be in writing, signed by both parties, and witnessed under Family Property and Support Act § 61. Beyond these statutory formalities, four practical requirements determine enforceability: full financial disclosure, independent legal advice for each spouse, voluntary execution without duress, and substantive fairness. Courts apply roughly the same standard to a cohabitation agreement that later converts to a marriage contract.
The core formal and practical requirements break down as follows:
- Written form, signed by both parties, and witnessed (Family Property and Support Act § 61)
- Full financial disclosure, including a business valuation at the date of signing
- Separate independent legal advice from two different lawyers
- Voluntary signing without pressure, ideally weeks before the wedding
- No predetermined parenting arrangements or waived child support
Financial disclosure is the most common pressure point for business owners. The classic challenge involves an undisclosed business interest or concealed income. A business valuation prenup that attaches a formal valuation at execution dramatically reduces the risk a court later sets the agreement aside for inadequate disclosure.
How Canadian Courts Evaluate Business Prenups
Canadian courts enforce a properly executed business prenup even when the outcome later feels unfair to one spouse. The governing authorities are Hartshorne v. Hartshorne, 2004 SCC 22, and Miglin v. Miglin, 2003 SCC 24, decisions of the Supreme Court of Canada that apply in Yukon. In Hartshorne, the husband entered marriage with $1.6 million in assets and the wife with none; the Court upheld their separate-property agreement even though the wife's own lawyer had called it grossly unfair.
The analysis proceeds in two stages. First, courts examine the circumstances at formation: was there duress, undue influence, lack of disclosure, or absence of independent legal advice? Second, courts ask whether circumstances changed so dramatically that enforcement is now unfair. Where the parties contemplated the changed circumstances at signing, the burden to prove unfairness is heavier. For business owners, this means a prenup anticipating business growth is more defensible than a silent one. Rick v. Brandsema, 2009 SCC 10, adds that deliberately defective financial disclosure is the strongest ground for setting an agreement aside, reinforcing why a documented valuation protects your LLC prenup.
Cost of a Business Prenup Versus Litigation
A Yukon business prenup costs $1,500 to $5,000 to draft, compared with $15,000 to $50,000 for contested property litigation. For a business owner, the agreement functions as inexpensive insurance: a $3,000 contract can protect a company worth hundreds of thousands or millions of dollars from a divisible-asset claim. Complex agreements involving formal business valuations or international assets cost more and can take three to six months to finalize.
| Item | Typical Cost (2026) |
|---|---|
| Standard marriage contract | $1,500-$5,000 per couple |
| Independent legal advice (per spouse) | Often included or $500-$1,500 |
| Formal business valuation | $2,000-$10,000+ depending on complexity |
| Contested property litigation | $15,000-$50,000 |
| Divorce filing fee (Supreme Court of Yukon) | $190 ($180 + $10 Central Registry) |
These figures are estimates as of June 2026. Verify professional fees directly with a Yukon family law lawyer and the court filing fee with your local clerk. The cost asymmetry is the central case for an entrepreneurial prenup: a few thousand dollars now avoids tens of thousands in legal fees and the risk of forced business sale or buyout later.
Common-Law Business Owners and Cohabitation Agreements
Yukon extends automatic property division to common-law couples after two years of cohabitation, or earlier if they share a child, making a cohabitation agreement essential for unmarried entrepreneurs. Under Family Property and Support Act § 60, two cohabiting persons may agree on their respective rights and obligations during cohabitation or on ceasing to cohabit, including how a business is treated.
A strategically important feature is conversion. Under Family Property and Support Act § 60(2), if cohabiting parties who signed a cohabitation agreement subsequently marry, the agreement is deemed to be a marriage contract unless it states otherwise. This means a single document drafted during cohabitation can protect business prenup interests continuously through both the common-law and married phases of a relationship. The same validity rules apply: written form, signatures, witnessing, disclosure, and independent legal advice. Yukon also removed, in a 2021 amendment, the prior time limit for common-law spouses to apply for spousal support, increasing the value of addressing support obligations expressly in your cohabitation agreement.
Filing and Court Logistics in Yukon
Divorce in Yukon is filed exclusively at the Supreme Court of Yukon in Whitehorse, the only court with jurisdiction to grant a divorce in the territory. The filing fee is $180 plus a $10 Central Registry fee, totaling $190 as of June 2026. At least one spouse must have been ordinarily resident in Yukon for 12 months before commencing the proceeding under Divorce Act, R.S.C. 1985, c. 3, s. 3(1).
The primary document is the Statement of Claim (Family Law – Divorce), Form 91A under Supreme Court Rule 63. The Registry sits at the Law Courts Building, 2134 Second Avenue, Whitehorse, and accepts cash, debit in person, cheque, money order, Visa, or MasterCard. A marriage contract excluding your business does not get filed with the court at the time of signing; it operates privately and is produced only if property division becomes contested. Self-represented filers should budget roughly $190 to $400 total, including process server fees of $100 to $200. The Family Law Information Centre offers free procedural help. Always verify the current filing fee with the Supreme Court of Yukon Registry, as fees change.
