Can You Change a Will After It’s Signed in Ontario?

13 Apr Can You Change a Will After It’s Signed in Ontario?

Many people assume once a will is signed, it’s final. In reality, Ontario law allows individuals to update or revise their will as their circumstances change. Keeping your will up to date is essential to ensuring your wishes remain clear, valid, and enforceable under current law.

A Will Isn’t Set in Stone

Under Ontario law, a signed will can be changed at any time, as long as the person making the will (the “testator”) has the legal capacity to do so. Life evolves – and your estate plan should evolve with it. 

However, changes must be made using proper legal methods. Informal edits, handwritten notes, or crossing things out may not be legally valid and can create confusion or disputes later.

Key Legal Updates You Should Know

Ontario has seen important changes to its estate laws in recent years directly affecting wills:

• Marriage no longer revokes a will: As of January 1, 2022, getting married does not automatically cancel an existing will.
• Separated spouses: As of January 1, 2025, separated spouses may now be treated similarly to divorced spouses in certain inheritance situations, meaning they could lose entitlement under a will.
• Divorce still impacts gifts: Divorce continues to revoke gifts and executor appointments related to a former spouse, but it does not invalidate the entire will.

These updates make it more important than ever to regularly review your will, especially after relationship changes.

Common Life Events Triggering Updates

Even with the newer laws, major life events still require careful review of your estate plan:

• Marriage or remarriage
• Separation or divorce
• Birth of adoption of children
• Significant financial changes (property, business ownership, inheritance)

Failing to update your will after these milestones can lead to unintended beneficiaries or outdated instructions remaining in place.

How to Legally Change a Will in Ontario

There are two proper ways to update a will:

1. Create a new will: This is often the best option if multiple changes are needed or if your circumstances have significantly changed.
2. Use a codicil: A codicil is a formal amendment to your existing will and must be signed and witnessed with the same legal requirements as the original document.

If these legal formalities are not followed, the changes may be invalid.

Why Informal Changes Can Cause Problems

It may seem simple to make quick edits to your will, but doing so improperly can create serious legal issues. Courts may ignore handwritten changes or unclear instructions, adn this can lead to disputes among family members.

Why Legal Advice Matters

Given the recent legal changes in Ontario, working with an estate lawyer is more important than ever. Professional guidance ensures that:

• Your will complies with current laws
• Your wishes are clearly documented and enforceable
• Risks of disputes or litigation are minimized
• Updates reflect both your personal circumstances and legal realities.
