If you’re planning to get married, you may be wondering whether you should create a prenup — and whether you can do it yourselves. Many couples search for a DIY prenup, download a prenup agreement template, or ask whether they really need a lawyer for a prenup.
This article explores what is a prenup agreement, what is the purpose of a prenup, why couples consider a DIY prenup, and the real legal risks involved under Canadian law. The goal is not to discourage proactive planning, but to help you make an informed decision about whether a DIY prenup agreement is right for you.
A prenup agreement (also called a marriage contract in many provinces) is a written contract created before marriage that sets out how property, finances, and support will be handled during the marriage and if the marriage ends.
Understanding what is a prenup agreement is the first step. In Canada, prenups are recognized across all provinces and territories, although the specific rules about property division and spousal support vary by jurisdiction.
A prenup agreement can override certain default legal rules that would otherwise apply to married spouses. Without one, provincial legislation determines how property is divided and whether spousal support is payable.
So, what is the purpose of a prenup?
The purpose of a prenup agreement is clarity and predictability. It allows couples to make intentional decisions about their financial future instead of relying on default legal frameworks that may not reflect their values or circumstances.
Common goals include:
For many couples, the purpose of a prenup is not about planning for divorce. It is about planning responsibly and transparently.
A DIY prenup generally means drafting your own agreement without traditional full-service lawyers managing the process from start to finish.
Couples who pursue a DIY prenup often:
The level of guidance varies widely. Some templates are bare-bones documents with fill-in blanks. Others provide structured questionnaires. The quality and reliability differ significantly.
There are practical reasons couples consider a DIY prenup.
Cost is often the biggest factor. People frequently ask how much does a prenup agreement cost, and traditional legal services can range from several thousand dollars per person depending on complexity and negotiation.
Accessibility also plays a role. Some couples prefer to work through issues privately and at their own pace. Others may live in areas with limited access to family lawyers.
Finally, many couples believe their situation is straightforward. If there are no children, limited assets, or aligned financial views, a DIY prenup can feel like a reasonable solution.
There are real advantages to a DIY prenup — especially compared to having no agreement at all.
A DIY prenup can:
For some couples, the conversation itself is one of the most valuable parts of the process. Working through financial disclosure and expectations can strengthen communication before marriage.
While a DIY prenup may seem straightforward, they also carry significant legal risks. This is where many couples run into problems.
One of the most common questions is whether a DIY prenup is legally binding. The answer is: it can be — but only if it meets legal requirements.
Across Canada, enforceability generally depends on:
If these conditions are not met, a court may set aside part or all of the agreement.
Common problems in DIY prenups include:
A signed document alone does not guarantee protection. False confidence is one of the biggest risks of relying solely on a generic prenup agreement template.
Unlike a purely DIY prenuptial agreement or a generic prenuptial agreement template, Jointly was built by lawyers with deep experience in Canadian family law. The platform has been reviewed by lawyers in every province and is customized to reflect province-specific legal requirements, rather than relying on one-size-fits-all language. While a DIY agreement often depends on guesswork and copied clauses, Jointly guides couples through the issues that actually matter under their provincial law and helps them create an agreement that reflects their real circumstances. The result is greater reliability, clearer expectations, and a level of customization that standard templates simply cannot offer, while still being far more accessible than traditional legal services.
There are situations where a DIY prenup agreement carries higher risk.
You should think carefully before drafting your own agreement if:
In these cases, professional guidance is strongly recommended. The cost of fixing a flawed prenup later can far exceed the cost of doing it properly at the outset.
Many couples ask whether they can start with a prenup agreement template and then obtain legal advice.In practice, this is a common and reasonable approach.
A template or guided online process can help you organize your thoughts and identify issues to discuss. Legal advice can then be used to review the agreement, flag risks, and ensure it aligns with Canadian law. Independent legal advice isn’t required in all provinces, but it is recommended if you have the resources to do so.
This also addresses the common question: do you need a lawyer for a prenup? While not always strictly required, independent legal advice significantly increases the likelihood that your prenup will be enforceable.
Jointly guides couples through building a prenuptial agreement step by step using plain-language questions designed by family lawyers. Instead of relying on a generic prenuptial agreement template, the platform helps you identify the issues that actually matter under your provincial law, based on your finances and your relationship.
Jointly was built by lawyers, reviewed by lawyers in every province, and customized to reflect province-specific legal requirements. As you build your agreement, you are guided through structured financial disclosure and thoughtful decision-making around property, expenses, and support.
This approach keeps the affordability and accessibility people look for in a DIY option, while offering far greater reliability and customization than a template or blank document.
To improve the likelihood that your DIY prenup will hold up in court:
The most important takeaway is that having a conversation and creating some form of agreement is almost always better than doing nothing. The key is making sure that the agreement you create is reliable and based on the law in your province – a free template pulled from an illegitimate source, based on the law in another jurisdiction is unlikely to have the effect you want it to.
Jointly reduces that risk by combining lawyer-built structure with province-specific customization. If you are ready to create a thoughtful, reliable prenup agreement, you can start building your agreement today at jointly.ca.
The cost of a prenup agreement in Canada varies widely. A traditional lawyer-drafted prenup can range from $2,000 to $5,000 or more per couple depending on complexity and negotiation. Online options and guided platforms are typically more affordable while still providing structured support.
Yes, you can make a prenup without a lawyer. However, professional legal advice is strongly recommended to improve enforceability and ensure the agreement complies with provincial law.
A DIY prenup can be legally binding if it meets legal requirements such as full disclosure, voluntary consent, and compliance with family law legislation. Agreements that fail to meet these standards may be challenged in court.
To strengthen enforceability, start early, exchange complete financial disclosure, document your process, ensure clarity in drafting, and seek independent legal advice if possible. Using a province-specific, lawyer-built platform can also significantly reduce risk.
