Grounds, Deadlines, and Legal Strategy: When Can You Challenge a Will in Ontario?
If you are considering when —or if— you can challenge a will in Ontario, it is important to understand that not every disagreement leads to a successful claim. Ontario courts respect testamentary freedom, but they will intervene where a will does not reflect the true intentions of the deceased or fails to meet legal requirements.
Not every disappointed family member has standing to bring a will challenge.
In practice, Ontario courts will only entertain claims from people who can show a genuine financial interest in the estate. This usually includes beneficiaries under the current will, beneficiaries under a previous will, spouses, dependants, and sometimes creditors. Adult children who were financially independent are often surprised to learn that they do not automatically have standing unless other legal grounds exist.
This is one of the first issues an estate litigation lawyer assesses—because without standing, the court will not hear the case, no matter how unfair the situation may feel.
