In Ontario, a will can be contested if there are valid legal grounds such as lack of capacity, undue influence, fraud, or failure to comply with legal formalities. Contesting a will is a complex process, but it is an important way to ensure fairness, protect your inheritance, and uphold the true intentions of the deceased.
⚠️ Red Flags: When to Consider Contesting a Will
Be alert to these common warning signs that may justify challenging a will:
❌ The deceased was pressured or manipulated into signing the will
❌ The will leaves out close family members without explanation
❌ The testator was suffering from cognitive decline or incapacity
❌ Multiple, conflicting versions of the will exist
❌ Suspicious last-minute changes that benefit one person disproportionately
💡 Next step: Preserve all copies of the will, gather supporting documents, and consult with an estate litigation lawyer immediately.
📜 Grounds for Contesting a Will in Ontario
Ontario law recognizes several legal grounds on which a will may be challenged:
- Lack of Testamentary Capacity – The testator did not have the mental capacity to understand what they were signing.
- Undue Influence – The testator was coerced, pressured, or manipulated into changing their will.
- Lack of Proper Formalities – The will does not meet the legal requirements under the Succession Law Reform Act (e.g., improper witnessing).
- Fraud or Forgery – The will was altered, falsified, or not genuinely signed by the testator.
- Dependants’ Relief Claims – Certain dependants may contest if they were not adequately provided for under the will.
📌 A will contest must be filed within strict timelines, making early legal action essential.
🛠️ Legal Actions You Can Take
If you believe a will is invalid or unfair, you may be able to:
- File a court application to challenge the validity of the will
