Ontario Estate Disputes Guide: Wills, Executors and Inheritance Questions

If you disagree with a will or have concerns about how an estate is being managed, first identify the specific issue. A challenge to a will, a request to interpret its wording and a concern about estate accounts can involve different legal questions.

Can a Will Be Challenged in Ontario?

Yes, but disappointment with an inheritance is not by itself a complete legal basis for a challenge. Issues may include the will-maker’s capacity, undue influence, fraud or the requirements for making a valid will. Your interest in the estate, the evidence and the remedy you seek need to be assessed. Source: CLEO’s Steps to Justice.

What Is Undue Influence in a Will Dispute?

Undue influence concerns pressure that affects the making of a will. A change in beneficiaries can prompt questions, but the change alone does not establish that someone was improperly pressured. Relevant circumstances and evidence about what happened when the will was made require careful review. Read CLEO’s explanation of pressure and will challenges.

What If the Wording of a Will Is Unclear?

An interpretation issue is different from saying that the entire will is invalid. Where wording is unclear or there is disagreement about how the estate trustee reads it, legal advice can help determine whether clarification or a court interpretation is needed. Source: Steps to Justice.

What Can I Do If an Executor Is Not Providing Information?

Identify the documents or explanation you are seeking and keep a record of requests and responses. Your relationship to the estate matters when assessing what information you are entitled to receive. Ontario’s court procedures include a passing of accounts, which is a formal review of estate accounts; it is not automatically the right first step in every disagreement. Source: Ontario estate court forms.

Is There One Deadline for Every Estate Claim?

No. Different claims can have different deadlines and triggering events. Do not assume that the date of death, the date you saw a will or the date probate was granted starts the same deadline for every issue. Tell your lawyer about all relevant dates and any planned distribution.

For example, dependant-support applications have a specific limitation provision in section 61 of the Succession Law Reform Act, with an exception concerning undistributed estate property. That provision is not a universal deadline for all will challenges. Source: Succession Law Reform Act, sections 58–61.

Can an Estate Dispute Be Resolved Without a Trial?

A trial is not the only possible route. Depending on the dispute, the parties may explore negotiation, mediation or a settlement. Whether an agreement is appropriate depends on the evidence, the people involved and any approval requirements. Ask your lawyer to explain the available process, likely steps and costs for your case.

Who Pays the Legal Fees in an Estate Dispute?

Do not assume that the estate will pay everyone’s legal fees. Discuss your retainer, the cost of each proposed step and potential exposure to another party’s costs before proceeding. The outcome of a costs decision depends on the case and the court’s discretion. Source: Rules of Civil Procedure, Rule 57.

What Evidence Should I Prepare for a Consultation?

Gather documents already available to you: wills and codicils, estate correspondence, relevant court papers and financial records. Make a dated timeline and separate what you personally observed from what someone else told you. Preserve originals and ask how to share copies securely. Do not access another person’s private accounts without authority.

How Does Estate Litigation Differ From Estate Planning?

Estate planning prepares documents and arrangements for the future. Estate litigation deals with a disagreement involving an estate. If you need to prepare a will or powers of attorney, read our Ontario wills and estates guide. If a dispute has already arisen, explore our estate litigation services.
