Protect Business Assets with a Prenuptial Agreement

Need To Know

In Canada, even if you started your business before getting married, any growth in its value during the marriage could be divided if you divorce—unless you have a prenup that says otherwise. A prenuptial agreement lets you clearly define your business as separate property, protect future income, and safeguard assets like shares, intellectual property, and retirement accounts tied to your company. It’s the smartest way to ensure your hard work stays yours and avoid costly disputes later, all while strengthening your relationship through honest financial planning.

Whether you’re launching a new venture or growing a business you’ve poured years into, protecting your business assets is key – especially when marriage is on the horizon. Many entrepreneurs don’t realize that their company could be at risk during a divorce, even if it was started before the marriage.

The good news? A prenuptial agreement can provide clarity and protection for your business and your future.


Why Protect Business Assets Before Marriage?

What Are Premarital Property and Business Assets?

In Canada, premarital property refers to assets you owned before getting married. This includes:

  • A business you started or invested in before marriage
  • Real estate, savings, or investments in your name
  • Intellectual property or shares

While some provinces exclude the value of premarital property from equal division during divorce, any increase in value during the marriage may be shared – unless you have a prenup in place that says otherwise.

If your business grows during your marriage – or if your partner contributes financially or otherwise – it may become subject to division in the event of a divorce. A prenup helps you define boundaries from the start.


How Can a Pre-Marriage Agreement Help?

A pre-marriage property agreement – commonly known as a prenup – lets couples decide in advance how assets, including business interests, will be treated during the marriage and in the event of a separation.

For business owners, a prenup can:

  • Clarify that your business is separate property
  • Exclude future increases in value from division
  • Protect company shares or intellectual property
  • Prevent your partner from claiming part ownership or control


This isn’t about anticipating failure. It’s about planning wisely – just like you would with an insurance policy or shareholder agreement.


Key Benefits of a Prenup for Business Owners

Protecting Business Ownership with a Prenup

Without a prenup, your spouse could:

  • Claim a share of your business if its value increased during the marriage
  • Seek a payout that affects your company’s cash flow
  • Challenge ownership of assets or equity you thought were yours alone

A prenuptial agreement can state clearly that your business ownership remains separate, including how any future growth or dividends will be treated.

This helps ensure that personal issues don’t impact your professional life or the people you employ and serve through your business.

Keeping Finances Separate to Safeguard Assets

If you’ve built your business using personal savings, loans, or family support, a prenup can protect those efforts by keeping your finances separate. This can include:

  • Business accounts and revenue
  • Real estate owned through your company
  • Retirement accounts connected to the business
  • Personal loans or guarantees made for the business

By keeping finances separate and documenting them clearly, you reduce the risk of conflict or claims down the line.


Including Future Assets in Your Prenuptial Agreement

Can a Prenup Include Assets Acquired After Marriage?

Yes. Many people think a prenup only protects what you already own – but you can also address future assets.

For example, your prenup can include:

  • Future business income or expansion
  • Royalties or intellectual property you haven’t created yet
  • Inheritances or large financial gifts
  • Real estate or investments acquired during the marriage

If you’re asking, “Can a prenup include future assets?” – the answer is absolutely, as long as the agreement is drafted clearly and with full disclosure.

Protecting Retirement Accounts and House Equity

A prenup can also protect:

  • Retirement savings connected to your business (like RRSPs or pensions)
  • Home equity in a property you owned before marriage or purchased using business funds

Without a prenup, the increase in your home’s value – or contributions that you make during the marriage – may be subject to division, even if you were the sole owner on paper.


Steps to Protect Your Assets Before Marriage

Do You Have to Get a Prenup Before Marriage?

A prenup isn’t mandatory, but it’s strongly recommended. Prenups are designed to be signed before the wedding. If you’re already married, you can create a postnuptial agreement, which offers the same protection.

Whether you’re drafting a prenup or postnup, the key is to start the conversation early. The more time you have to create the agreement thoughtfully – and without pressure – the better it will hold up legally.

With platforms like Jointly, you can walk through the process step-by-step, on your schedule and without the high costs of traditional legal services.

Ensuring Full Financial Disclosure for Enforceability

For a prenup to be valid and enforceable in Canada, both partners must:

  • Disclose their finances fully (including business assets, income, and debt)
  • Understand the agreement (no legal jargon or confusion)
  • Sign voluntarily, without pressure or coercion

Without these elements, the agreement could be challenged in court. That’s why Jointly is designed to walk you through each step, making sure both partners are fully informed and confident before signing.


Protect Your Business and Your Relationship

You’ve worked hard to build your business. Don’t leave its future up to chance. A prenuptial agreement gives you the power to:

  • Define your ownership clearly
  • Protect your business from potential disruption
  • Strengthen your relationship with open, honest financial planning

At Jointly, we make it easy for Canadian entrepreneurs and their partners to create custom agreements that reflect their values and goals – without expensive legal fees.
