Prenups for Everyone: What the Super-Rich Can Teach Ontario Couples About Smart Planning

Written by Russell Alexander ria@russellalexander.com / (905) 655-6335

Prenuptial agreements are often associated with the ultra-wealthy—those with empires to protect, sprawling estates, and complicated family trees. But a recent Wall Street Journal article reveals that these agreements aren’t just about safeguarding yachts and private equity stakes. They’re about setting expectations, avoiding future disputes, and protecting what matters—no matter your income level.

At Russell Alexander Collaborative Family Lawyers, we believe that what works for billionaires can work just as well for everyday Ontarians.

What We Can Learn from the Wealthy

The WSJ article outlines how wealthy couples now approach prenuptial agreements not only to protect vast fortunes, but also to address seemingly small—and sometimes petty—details. Some include clauses about social media posts, household chores, or vacation destinations. Others anticipate future inheritances, stepchildren, or business interests.

The key takeaway? It’s not about being rich—it’s about being clear.

Why Ontario Couples Should Consider a Prenup

  1. Clarity Avoids Conflict: A well-drafted prenup ensures both partners understand what happens financially if the relationship ends. This avoids bitter disputes during separation or divorce.
  2. Protecting Pre-Marital Assets: If you own a business, expect a future inheritance, or have children from a previous relationship, a prenup can help preserve those interests.
  3. Customized for Your Life: Prenups in Ontario can address spousal support, division of property, and financial obligations—provided both parties receive independent legal advice and full financial disclosure.
  4. Not Just for the Wealthy: Anyone with assets, debt, or children from a prior relationship can benefit from a prenuptial agreement. It’s about protecting the life you’ve built and the one you’re planning.

Key Considerations Under Ontario Law

In Ontario, prenuptial agreements (called marriage contracts under the Family Law Act) are enforceable if:

  1. Both parties entered the agreement voluntarily
  2. Each party received independent legal advice
  3. Financial disclosure was complete and honest
  4. The terms are not unconscionable at the time of enforcement

The super-rich may have more zeros at stake, but the principles behind their prenuptial agreements apply across the board. Whether you’re entering your first marriage, blending families, or remarrying later in life, a prenup provides a foundation of trust and transparency.

At Russell Alexander Collaborative Family Lawyers, we help couples in Ontario design prenuptial agreements that are fair, enforceable, and built to last. Planning ahead doesn’t mean planning for divorce—it means planning with respect.
