What Cannot Be Included in a Prenuptial Agreement Under Prince Edward Island Law?

7 Jun 2026 7 min read No comments Marriage Contracts & Prenups Prince Edward Island
⚠️

Under Prince Edward Island law, a prenuptial agreement cannot legally determine parenting time, decision-making responsibility, or child support for your future children. The Supreme Court of Prince Edward Island will always prioritize the best interests of the child. Drafting an agreement that ignores these rules can render your contract invalid.

Planning a wedding in beautiful locations like Charlottetown, Summerside, or Stratford is an incredibly exciting milestone. However, before walking down the aisle, many Canadian couples wisely choose to safeguard their financial futures. A marriage contract, commonly known as a prenuptial agreement, is a vital legal document that allows partners to decide exactly how they will divide their property and handle spousal support if the relationship ends. While these contracts are excellent for protecting assets and providing peace of mind, it is critical to understand what cannot be included in a prenuptial agreement under Prince Edward Island law .

Including forbidden clauses can have disastrous consequences. If a judge discovers that your agreement violates basic family law principles or public policy, they may strike down the offending clauses or even invalidate the entire document. The family law system in Canada strictly protects vulnerable individuals, particularly children, meaning you cannot lock in certain life decisions before they happen. If you want to ensure your contract holds up in the Supreme Court of Prince Edward Island, it is highly recommended to seek guidance from a local lawyer in our directory 📝.

What Cannot Be Included in a Prenuptial Agreement Under Prince Edward Island Law?

When you draft a marriage contract in PEI, the provincial Family Law Act sets very clear boundaries on what can be legally enforced. You have the freedom to organize your financial affairs, but you cannot contract out of fundamental human rights or child protection laws. Here are the primary elements you must leave out of your agreement.

1. Parenting Time and Decision-Making Responsibility

Under updated Canadian family laws, courts no longer use the outdated terms “custody” and “access.” Today, we refer to these concepts as “parenting time” and “decision-making responsibility.” You absolutely cannot use a prenup to dictate who will live with the children or how major parenting decisions will be made in the event of a separation 👪. A judge in Prince Edward Island will always make these determinations based on the “best interests of the child” at the exact time of the separation, completely ignoring any prior contract you signed.

2. Child Support Obligations

In Canada, child support is considered the absolute legal right of the child, not a bargaining chip for the parents. Therefore, you cannot include any clause that attempts to waive, limit, or cap child support payments for future or existing children. The amount of child support is strictly determined by the Federal Child Support Guidelines. The Canada Revenue Agency (CRA) and the local courts will firmly reject any private arrangement that attempts to bypass these mandatory financial protections .

3. Unconscionable Spousal Support Waivers

Couples are generally allowed to agree on the terms of spousal support in a marriage contract. For example, you might agree to waive it entirely or cap it at a certain amount. However, if a clause leaves one spouse in a state of severe financial hardship or forces them to rely on provincial welfare programs, the court may refuse to enforce it. The Supreme Court of Prince Edward Island has the authority to overturn spousal support waivers that are deemed “unconscionable” or deeply unfair at the time of the divorce.

4. Clauses Regulating Personal Behaviour

Some couples try to include “lifestyle clauses” in their prenups. These might dictate how often a partner must exercise, impose financial penalties for gaining weight, or set strict rules about social media usage. Under Prince Edward Island law, these types of clauses are generally unenforceable. Canadian courts view marriage contracts as financial and property planning tools, not mechanisms to control a spouse’s personal behaviour or lifestyle choices 🚫.

5. Complete Forfeiture of Matrimonial Home Rights

The family residence, known as the matrimonial home, holds a very special, protected status under the PEI Family Law Act. You cannot write a simple clause that gives one spouse the immediate right to evict the other upon separation. Both legally married spouses have an equal right to possess and live in the family home, regardless of whose name is actually on the property deed. Restricting these rights requires careful, specific legal drafting that complies with provincial statutes.

Step-by-Step Guide to Drafting a Valid Prenup in Prince Edward Island

Whether you live in a bustling centre like Charlottetown or a quieter rural community, the process for creating a legally binding marriage contract remains the same. Following a structured process ensures that both partners are protected and the agreement is legally sound.

Step 1: Discussing Your Goals and Financial Realities

The first step is having an open and honest conversation with your partner about your financial expectations. You need to gather all relevant documents, including recent tax returns, CRA notices of assessment, bank statements, and property appraisals. Full financial disclosure is mandatory in Canada; hiding assets or downplaying debts can cause a judge to throw out the entire agreement later .

Step 2: Removing Unenforceable Elements

Once you have a general idea of what you want, you must filter out anything that cannot be legally enforced. Review the rules about what cannot be included in a prenuptial agreement under Prince Edward Island law, ensuring there are no mentions of future child support, parenting time, or illegal conditions.

Step 3: Seeking Independent Legal Advice (ILA)

This is arguably the most critical step in the entire process. Both you and your partner must hire separate, independent lawyers. One lawyer cannot represent both of you. Your respective lawyers will review the drafted contract, explain exactly how it impacts your rights under PEI law, and ensure that neither party is signing under duress or pressure 👮‍⚕️.

Step 4: Finalizing and Signing the Contract

After both lawyers are fully satisfied that the document is fair and compliant with the law, you will sign the contract in the presence of witnesses. Your lawyers will then sign a Certificate of Independent Legal Advice. This certificate acts as powerful proof that you fully understood the contract and signed it voluntarily.

How Much Does it Cost in Prince Edward Island?

Drafting a marriage contract involves upfront legal fees, but it is almost always less expensive than a drawn-out court battle during a divorce. Keep in mind that both partners will need to pay their own lawyer. Here is an overview of the typical costs you can expect in CAD:

ServiceEstimated Cost (CAD)
Basic Drafting (One Lawyer)$1,500 – $2,500
Review and ILA (Second Lawyer)$500 – $1,200
Complex Assets (Businesses, Trusts)$3,000 – $6,000+
Court Filing Fees (If litigated later)Varies, but initial filings often start around $100+

How Long Does the Process Take?

A properly drafted prenuptial agreement in PEI usually takes about 4 to 8 weeks from start to finish. This timeline provides enough space for full financial disclosure, the drafting of the initial document, and for both partners to meet privately with their lawyers. It is highly recommended to finalize your agreement at least three to four months before your wedding date ⌛. Signing a prenup the night before the wedding can easily lead to claims of duress, which might invalidate the contract entirely.

Frequently Asked Questions (FAQ)

Can we protect an inheritance in a PEI marriage contract?

Yes. Protecting family inheritances and gifts is one of the most common reasons couples sign a marriage contract. You can clearly stipulate that any money or property inherited during the marriage remains the sole property of the receiver and will not be divided upon separation.

Do we absolutely need two different lawyers?

Yes, obtaining Independent Legal Advice (ILA) requires two separate lawyers from different law firms. If you share a lawyer, or if one person does not get legal advice, the Supreme Court of Prince Edward Island may heavily scrutinize or invalidate the agreement because it is impossible to prove the unrepresented spouse fully understood their rights.

Can a prenuptial agreement include rules for pet ownership?

Generally, yes. In Canadian law, pets are legally considered property. Unlike children, you can include clauses that dictate who gets to keep the family dog or cat if the relationship ends. However, courts are increasingly viewing pets as more than just basic property, so drafting this carefully is essential.

What happens if we move outside of Prince Edward Island?

Marriage contracts are generally portable across Canada. However, family laws differ between provinces (for example, Quebec uses the Civil Code). If you move to another province, it is highly recommended to have a local lawyer review your contract to ensure it complies with the new jurisdiction’s laws.

Can we update the marriage contract after we are married?

Yes. If your financial situation changes significantly, or if you simply want to alter the terms, you and your spouse can sign an addendum or draft a completely new agreement. Both parties must agree to the changes in writing, and you should both seek independent legal advice again.
