An infidelity clause prenup in Prince Edward Island is generally unenforceable because Canada operates under a no-fault divorce system established by the Divorce Act, R.S.C. 1985, c. 3. Under this federal framework, courts will not impose financial penalties for marital misconduct such as adultery. While couples can include cheating prenup penalty provisions in their marriage contracts, PEI courts following the precedent set by LeVan v. LeVan (2008 ONCA 388) consistently refuse to enforce clauses that punish personal behavior rather than address legitimate financial matters.

What Is an Infidelity Clause in a Prince Edward Island Prenuptial Agreement?
An infidelity clause in a PEI prenuptial agreement is a contractual provision that imposes financial consequences on a spouse who commits adultery during the marriage. These adultery clause prenuptial provisions typically specify penalty payments ranging from $50,000 to $500,000 or more, forfeiture of property rights, or increased spousal support obligations if infidelity is proven. Under Prince Edward Island's Family Law Act, RSPEI 1988, c F-2.1, marriage contracts (prenuptial agreements) are authorized under Section 51, which permits couples to agree on their respective rights and obligations regarding property division and spousal support. However, the Act does not authorize provisions designed to punish personal misconduct.
The legal distinction between enforceable and unenforceable prenup provisions centers on whether the clause addresses legitimate economic interests or attempts to regulate personal behavior. Prince Edward Island courts, following established Canadian jurisprudence, consistently hold that marriage contracts should deal with financial consequences of marriage breakdown, not attempts to control moral conduct during the relationship. According to a 2024 Ipsos Canada report, 15% of married or engaged Canadians now have a marriage contract, up from 8% in 2017, yet the vast majority of these agreements focus on property division rather than lifestyle clauses.
Why Cheating Prenup Penalty Clauses Are Unenforceable in PEI
Prince Edward Island courts refuse to enforce prenup cheating payout provisions because Canada's entire divorce framework operates on a no-fault basis, making adultery irrelevant to financial outcomes. The Divorce Act, R.S.C. 1985, c. 3, s. 8 establishes that the sole ground for divorce is breakdown of the marriage, which can be proven by one year of separation, adultery, or cruelty. However, critically, the Act does not permit courts to consider marital misconduct when dividing property or determining support amounts. This means that even when adultery is proven as grounds for divorce, it has zero impact on the financial settlement.
The landmark case LeVan v. LeVan (2008 ONCA 388) established binding precedent across Canadian common law provinces including Prince Edward Island. In this case, a prenuptial agreement included a clause requiring Mr. LeVan to pay a substantial sum to Mrs. LeVan if he committed adultery. When Mrs. LeVan discovered infidelity and sought to enforce this provision, the Ontario Court of Appeal struck down the clause as contrary to public policy. The court reasoned that imposing financial penalties for personal misconduct was punitive rather than compensatory and did not align with matrimonial law principles. This decision has been judicially considered 17 times and remains binding law.
Additionally, Section 55 of the PEI Family Law Act explicitly states that provisions in domestic contracts dependent upon a party remaining chaste are unenforceable. While this section does not affect clauses contingent upon remarriage or cohabitation with a new partner, it directly prohibits what amounts to fidelity requirements in marriage contracts.
Legal Requirements for Valid Marriage Contracts in Prince Edward Island
A marriage contract in Prince Edward Island must meet specific formal requirements under the Family Law Act to be enforceable in any capacity. Understanding these requirements helps couples create agreements that courts will uphold for legitimate financial matters, even if lifestyle clause prenup provisions would be severed.
To be valid, a PEI marriage contract must be:
- In writing (oral agreements are not enforceable)
- Signed by both parties
- Witnessed by at least one person
- Entered into voluntarily without duress or coercion
- Made with full financial disclosure from both parties
- Fair and not unconscionable at the time of enforcement
The financial disclosure requirement is particularly critical. In LeVan v. LeVan, the trial court set aside the entire marriage contract primarily because the husband had breached his statutory obligation to provide adequate financial disclosure. The wife received an equalization payment of $5.3 million after the agreement was invalidated. Courts consistently hold that full and frank disclosure is a foundation stone of every domestic contract.
While not explicitly mandated by statute, obtaining independent legal advice is strongly recommended. The absence of independent legal advice may influence a court's decision regarding the fairness and enforceability of the agreement. PEI courts retain discretion to set aside a marriage contract if a party did not understand the nature or consequences of the agreement.
What Marriage Contracts Can and Cannot Include Under PEI Law
Under Section 51 of the PEI Family Law Act, marriage contracts can address specific financial matters while certain subjects are expressly prohibited or practically unenforceable.
Permitted Subjects in PEI Prenuptial Agreements
- Ownership or division of property (pre-marital, marital, business, real estate)
- Spousal support obligations including amount, duration, or waiver
- Debt division and financial management responsibilities
- Rights upon death of a spouse
- Estate planning provisions
- Business succession arrangements
Prohibited or Unenforceable Subjects
- Parenting time, decision-making responsibility, or contact with children (explicitly prohibited under Section 51(1)(c))
- Chastity clauses or fidelity requirements (unenforceable under Section 55)
- Infidelity penalty clauses (contrary to public policy)
- Lifestyle clauses regulating personal behavior (generally unenforceable)
- Provisions that are unconscionable or grossly unfair
The prohibition on parenting arrangements is absolute. Section 51(1)(c) of the Family Law Act explicitly prevents agreements from addressing parenting time, decision-making responsibility, or contact with children. These matters are always subject to court determination based on the best interests of the child under the Children's Law Act and the federal Divorce Act.
Alternatives to Infidelity Clauses That PEI Courts May Enforce
While direct infidelity clause prenup provisions are unenforceable in Prince Edward Island, couples seeking financial protection can draft alternative provisions that address legitimate economic concerns without attempting to penalize personal conduct.
Tiered Support Provisions Based on Marriage Length
Couples can agree that spousal support obligations increase with the length of the marriage. For example, a provision stating that spousal support will equal 1.5% of the payor's income for each year of marriage, up to a maximum of 15 years, addresses legitimate financial reliance without referencing conduct. This approach acknowledges that longer marriages create greater financial interdependence.
Sunset Clauses with Automatic Adjustments
Sunset clauses allow prenuptial agreements to expire after a set number of years or automatically update based on changes in income or net worth. A clause providing that property division provisions expire after 15 years of marriage, at which point standard equitable division applies, may be enforceable because it addresses economic realities rather than behavior.
Enhanced Property Protection for Pre-Marital Assets
Rather than penalizing infidelity, couples can protect pre-marital assets through clear exclusion provisions. A clause stating that any property owned before marriage, plus all appreciation, remains the separate property of the original owner addresses asset protection without behavioral conditions.
Lump Sum Provisions Without Behavioral Conditions
Agreements can provide for specific lump sum payments upon divorce without conditioning those payments on conduct. For example, providing that the lower-earning spouse shall receive $200,000 upon divorce after 10 years of marriage is more likely enforceable than conditioning the same payment on proving fidelity.
How Courts Evaluate Prenuptial Agreement Fairness in PEI
Prince Edward Island courts apply a multi-factor analysis when determining whether to enforce marriage contract provisions. Even properly executed agreements may be varied or set aside if circumstances at enforcement make application unjust.
Factors Courts Consider
- Whether both parties had independent legal advice
- Completeness of financial disclosure
- Whether either party was under duress or undue influence
- Understanding of the agreement's nature and consequences
- Fairness of the agreement at the time of signing
- Changes in circumstances since signing
- Whether provisions create unconscionable results
Courts distinguish between agreements that are merely unfavorable and those that are unconscionable. An agreement that results in one spouse receiving less than they would under statutory default rules is not automatically invalid. However, an agreement that leaves one spouse destitute while the other retains substantial wealth may be set aside as unconscionable.
The timing of signing also matters. Agreements signed under time pressure immediately before marriage receive greater scrutiny than those negotiated months in advance with adequate opportunity for reflection and negotiation.
The Impact of the 2021 Divorce Act Amendments on PEI Prenuptial Agreements
The Divorce Act amendments that came into force on March 1, 2021, marked the first substantive changes to federal family laws in more than 20 years and have implications for prenuptial agreements in Prince Edward Island. These amendments reinforced Canada's no-fault divorce framework while modernizing terminology and procedures.
Key changes include replacing the terms custody and access with decision-making responsibility and parenting time. This terminological shift reflects the understanding that children benefit from ongoing relationships with both parents and that parenting arrangements should focus on the child's needs rather than parental rights.
The 2021 amendments also introduced comprehensive family violence provisions. Courts now consider not just physical violence but patterns of coercive control, financial abuse, threats, and psychological harm when making parenting orders. These provisions may affect how courts evaluate prenuptial agreements that were signed in contexts involving power imbalances or controlling behavior.
The amendments established clear relocation procedures requiring 60 days written notice before a parent with parenting time or decision-making responsibility can relocate, with the other parent having 30 days to object. While prenuptial agreements cannot override these statutory requirements, couples should be aware that any provisions attempting to pre-determine relocation outcomes would be unenforceable.
Proving Infidelity: Practical Challenges Even If Clauses Were Enforceable
Even hypothetically, enforcing an adultery clause prenuptial agreement would present substantial evidentiary challenges. Understanding these difficulties illustrates why such provisions are impractical regardless of their legal status.
Definition Ambiguities
Prenuptial agreements attempting to define infidelity must grapple with questions of what constitutes cheating. Does emotional infidelity count? What about online relationships without physical contact? Kissing? Different couples may have different understandings, and proving violation requires clear definitions that often fail to capture complex human behavior.
Burden of Proof Issues
The accusing spouse bears the burden of proving infidelity by a balance of probabilities. This typically requires evidence beyond suspicion, such as:
- Direct witness testimony
- Electronic communications (text messages, emails)
- Financial records showing unexplained expenditures
- Photographs or video evidence
- Private investigator reports
Gathering such evidence often involves significant expense and may raise privacy concerns or even criminal liability for unauthorized surveillance.
Timing and Duration Questions
Questions arise about when alleged infidelity occurred, whether it was ongoing or a single incident, and whether the marriage had already broken down before the conduct occurred. A single act of infidelity years before separation presents different considerations than an ongoing affair discovered recently.
Cohabitation Agreements and Common Law Relationships in PEI
Prince Edward Island's Family Law Act treats common law relationships differently than marriages for certain purposes, which affects how agreements between unmarried couples are treated.
Under Section 52 of the PEI Family Law Act, cohabitation agreements allow unmarried couples to define their rights and obligations. For property division purposes, the Act uses a narrow definition of spouse that only covers legally married persons. However, for spousal support, the definition expands to include couples who have lived together in a conjugal relationship for at least three years, or who are living together and are natural or adoptive parents of a child.
If parties to a cohabitation agreement subsequently marry, the agreement is typically deemed to be a marriage contract. This transformation means that any infidelity clauses in the original cohabitation agreement would become subject to the same enforceability limitations as those in prenuptial agreements.
The same principles regarding infidelity clause prenup unenforceability apply to cohabitation agreements. Courts will not enforce provisions that impose financial penalties for moral misconduct regardless of the parties' marital status.
Steps to Create an Enforceable Marriage Contract in Prince Edward Island
Couples who want to create a marriage contract that will withstand court scrutiny should follow these steps, focusing on legitimate financial protections rather than unenforceable lifestyle clauses.
Step 1: Complete Full Financial Disclosure
Both parties must provide comprehensive disclosure of all assets, debts, income sources, and financial expectations. This includes:
- Bank account statements
- Investment portfolio valuations
- Real estate appraisals
- Business valuations
- Pension statements
- Tax returns (typically 3 years)
- Disclosure of any expected inheritances
Step 2: Obtain Independent Legal Advice
Each party should retain their own lawyer to review the agreement and explain its implications. The lawyers should provide certificates of independent legal advice confirming that their client understood the agreement's nature and consequences.
Step 3: Allow Adequate Time for Consideration
Agreements signed immediately before marriage receive heightened scrutiny. Ideally, the agreement should be substantially negotiated and signed several months before the wedding to demonstrate that neither party was under time pressure.
Step 4: Focus on Enforceable Provisions
Concentrate on property division, spousal support, and other financial matters that courts will enforce. Avoid provisions attempting to regulate behavior, impose penalties for conduct, or predetermine parenting arrangements.
Step 5: Include Severability Clauses
Include provisions stating that if any clause is found unenforceable, the remainder of the agreement remains valid. This protects the enforceable portions if a court strikes down specific provisions.
Step 6: Plan for Review and Updates
Include provisions for periodic review, such as every five years or upon major life events (birth of children, significant income changes). This demonstrates ongoing fairness and mutual consideration.
Cost Considerations for Prenuptial Agreements in Prince Edward Island
Creating a properly drafted marriage contract in PEI involves various costs that couples should budget for when planning their agreement.
| Cost Category | Estimated Range |
|---|---|
| Simple prenup (lawyer drafted) | $1,500 - $3,000 |
| Complex prenup (significant assets) | $5,000 - $15,000 |
| Independent legal advice (per party) | $500 - $1,500 |
| Business valuation (if required) | $2,500 - $10,000 |
| Real estate appraisal | $350 - $500 |
| Financial disclosure preparation | $500 - $2,000 |
The total cost for a comprehensive marriage contract with proper legal advice typically ranges from $4,000 to $20,000 depending on complexity. While this represents a significant investment, it is substantially less than the cost of contested divorce litigation, which can easily exceed $50,000 to $100,000 in complex cases.
The divorce filing fee in PEI is $100 as of March 2026, though couples should verify current fees with the Supreme Court of Prince Edward Island clerk's office. An uncontested divorce typically takes three to six months to complete, while contested divorces can extend for one to three years or longer.
Frequently Asked Questions
Can I include an infidelity clause in my Prince Edward Island prenup?
You can technically include an infidelity clause prenup provision in a PEI marriage contract, but courts will almost certainly refuse to enforce it. Under Canada's no-fault divorce system, financial penalties for adultery are considered contrary to public policy. The LeVan v. LeVan (2008 ONCA 388) decision established that such clauses are punitive rather than compensatory and do not align with matrimonial law principles. Courts will typically sever unenforceable clauses while preserving the rest of the agreement.
What happens if my spouse cheats and we have a prenup with an adultery clause?
If your spouse commits adultery and your prenup contains a cheating prenup penalty clause, PEI courts will not enforce that specific provision. Adultery can serve as grounds for divorce under the Divorce Act, R.S.C. 1985, c. 3, s. 8(2)(b), allowing you to divorce immediately without the one-year separation requirement. However, proving adultery will not entitle you to additional property or support beyond what the law otherwise provides. The court will apply the enforceable portions of your prenup and standard legal principles to unaddressed matters.
Are lifestyle clauses enforceable in Prince Edward Island prenuptial agreements?
No, lifestyle clause prenup provisions regulating personal behavior such as weight maintenance, social media usage, frequency of intimacy, or household responsibilities are generally unenforceable in PEI. Courts focus on financial matters and will not enforce clauses attempting to control personal conduct. Including such clauses does not typically invalidate the entire agreement, but those specific provisions will be disregarded. Focus your agreement on property division, spousal support, and legitimate financial concerns.
How does PEI's no-fault divorce affect prenuptial agreements?
PEI follows Canada's federal no-fault divorce framework under the Divorce Act, R.S.C. 1985, c. 3. This means 94.78% of divorces proceed based on one year of separation rather than proving fault. Because marital misconduct is irrelevant to property division and support calculations, provisions attempting to penalize misconduct conflict with this framework. Valid prenuptial agreements address the financial consequences of marriage breakdown without conditioning outcomes on either party's behavior.
Can a prenup in PEI waive spousal support entirely?
A prenup can include provisions waiving spousal support, but PEI courts retain discretion to disregard such waivers if enforcement would be unconscionable or create unfair results. Courts may override support waivers when one spouse has become economically disadvantaged through the marriage, when circumstances have changed significantly since signing, or when enforcement would leave one party destitute. The more unequal the parties' financial positions at separation, the more likely courts will modify or disregard support waivers.
What is the difference between a prenup and a cohabitation agreement in PEI?
A prenup (marriage contract) is made between people who are married or intend to marry, while a cohabitation agreement is made between unmarried partners living together. Both are governed by the PEI Family Law Act and must meet the same formal requirements. If cohabiting partners later marry, their cohabitation agreement typically becomes a marriage contract automatically. The same restrictions on infidelity clauses and parenting arrangements apply to both types of agreements.
How can I protect myself financially without an infidelity clause?
Protect yourself through enforceable provisions that address legitimate financial concerns. Consider enhanced property protection for pre-marital assets, tiered spousal support based on marriage duration, clear provisions for business interests, and lump sum payments upon divorce without behavioral conditions. Focus on documenting separate property, establishing clear boundaries between marital and non-marital assets, and creating fair arrangements that courts will enforce regardless of marital conduct.
Does Prince Edward Island recognize prenups from other provinces or countries?
PEI courts generally recognize marriage contracts validly executed in other jurisdictions, applying conflict of laws principles. However, any provisions that would be unenforceable under PEI law may still be disregarded when the parties divorce in PEI. Couples moving to PEI from other jurisdictions should have their agreements reviewed by a local family lawyer to understand how PEI courts might interpret specific provisions. Infidelity clauses would be unenforceable regardless of where the agreement was signed.
What makes a prenup unconscionable and therefore unenforceable in PEI?
A prenup becomes unconscionable when its terms are so unfair that enforcement would shock the conscience of the court. Factors include extreme disparity between parties' positions, exploitation of vulnerability or lack of understanding, absence of independent legal advice, failure to disclose significant assets, and results that leave one party destitute while the other retains substantial wealth. Even properly executed agreements may be set aside if circumstances at enforcement make application grossly unjust.
Can I modify or update my prenup after marriage in Prince Edward Island?
Yes, married couples can modify their marriage contract through a written amendment meeting the same formal requirements as the original agreement (written, signed, witnessed). Many couples include review provisions requiring periodic reassessment every five years or upon major life events. Modifications should address changed circumstances such as children, significant income changes, or asset acquisitions. Both parties should obtain fresh independent legal advice when making substantial modifications to ensure continued enforceability.
