How does a beneficiary file a formal objection to an estate trustee's accounts in Ontario court?

A beneficiary who disagrees with an estate trustee's accounts doesn't just write a letter of complaint — they file a formal notice of objection with the Superior Court, responding to the specific accounting the trustee has put before the court. The objection should identify exactly which entries are being challenged and why, whether that's a disputed expense, a questioned investment decision, or the compensation the trustee is claiming for their work.

Once an objection is filed, the matter generally proceeds toward a hearing where the trustee has to justify the challenged items with supporting records, and the objecting beneficiary gets the chance to make their case. This is different from simply refusing to sign an informal release — filing a proper objection preserves the beneficiary's position and puts the disputed items squarely in front of the court rather than leaving them unresolved.

Because vague or scattershot objections tend to go nowhere and can even expose the objecting beneficiary to a costs award if found unreasonable, it's worth being specific and evidence-based from the outset. Getting a lawyer to review the accounts before filing can help identify which items are genuinely worth challenging.
