When Sorry is Not Good Enough: Crucial Lessons from the Ontario Court of Appeal in Henderson v. Wang, 2025 ONCA 335

Estate litigation can be complex, and challenging a will is often an emotionally charged and demanding process. When a court decision doesn't go your way, the option of an appeal offers a second chance, but only if conducted meticulously and within strict legal parameters.  A recent decision from the Ontario Court of Appeal, Henderson v. Wang, 2025 ONCA 335, serves as a crucial reminder of the importance of following court procedures, communicating clearly, and having a meritorious appeal.  Henderson underscores why parties seeking an appeal must adhere to every rule, or risk having their matter dismissed.

In Henderson, the applicant/appellant, Susan Henderson, challenged the validity of her late mother’s 2018 Will. Susan was not named as a beneficiary in the 2018 Will, whereas she was a beneficiary in an earlier 2009 Will.  Susan alleged suspicious circumstances, a lack of testamentary capacity, and undue influence.  Susan’s application challenging the 2018 Will was dismissed by the judge hearing the application.  Susan then attempted to appeal the dismissal of her application.  Her initial notice of appeal was filed but not served by the March 20, 2025, deadline. The notice of appeal was rejected by the court on March 27, 2025, because of "various deficiencies, including that no proof of service had been provided".  Susan now needed an extension of time to proceed with her appeal. Susan’s motion for an extension of time was heard by the Ontario Court of Appeal.  Unfortunately for Susan, the Ontario Court of Appeal dismissed her appeal, resulting in her application being dismissed entirely.

The Ontario Court of Appeal applied a four-factor test when addressing Susan’s appeal:
  1. Intention to appeal: Did the party demonstrate an intent to appeal within the initial timeframe?
  2. Length of and explanation for delay: How long was the delay, and what caused it?
  3. Prejudice to the responding party: Will the other side be negatively impacted by the delay?
  4. Merits of the proposed appeal: Does the appeal have a reasonable chance of success?

The Ontario Court of Appeal held that the "justice of the case weighs against" granting the extension (and dismissing the appeal) for the following reasons:
  1. Unconvincing Explanation for Delay: While the Court accepted that Susan had a timely intention to appeal, her explanation for the delay in serving and filing the notice was problematic. She claimed she was "mistakenly advised by the court office" to wait for a court file number before serving. However, the Court firmly stated that Rule 61.04(1) of the Rules of Civil Procedure plainly requires an appeal to be commenced by "serving a notice of appeal…within 30 days," and Rule 61.04(4) requires filing with proof of service within 10 days after service. The Court emphasized that there is "no provision" for serving after a file number is assigned. Furthermore, her own evidence was inconsistent, as her timeline did not mention such advice, and she later characterized instructions as "unclear or incomplete" rather than incorrect.
  2. Lack of Meritorious Appeal: Perhaps the most decisive factor, the Court found the proposed appeal had "so little merit" that it had "no chance of success". Susan "pointed to no error of law" and primarily challenged the application judge’s "careful and thorough findings of fact and credibility". The lower court had found no suspicious circumstances, that Ruth Henderson had the necessary testamentary capacity, and that she made her Will without undue influence. The appeal raised no "arguable error" with these conclusions.
  3. Prejudice and Unreasonable Conduct: Despite the initial delay being relatively short, the Court highlighted Susan’s "actions in unreasonably delaying the filing...and then mischaracterizing and blaming the court office and the responding party and counsel". The decision noted a "long history of procedural misconduct" and a "pattern of delay". Critically, the Court stressed that "estate matters are expected to be administered promptly and efficiently". Almost six years had passed since Ruth Henderson's death, and the estate administration was incomplete. The estate trustee and beneficiaries were "entitled to finality" and "should not be required to expend further time and expense responding to a meritless appeal that only serves to deplete the estate".

Important Lessons Learned for Estate Litigants from Henderson

This decision offers invaluable insights for anyone involved in estate litigation, particularly those considering an appeal:
  1. Strict Adherence to Rules of Civil Procedure is Paramount: Do not assume or rely on informal advice over the clear, written rules. It is your responsibility to understand and strictly follow deadlines and requirements for serving and filing documents. Missing deadlines or failing to provide proof of service can be fatal to your appeal.
  2. Provide Credible and Consistent Explanations for Delay: If you need an extension, your explanation for delay must be believable and consistent across all your evidence. Inconsistent narratives or blaming others without clear justification will undermine your credibility.
  3. Your Appeal Must Have Substantive Merit: An appeal is not a chance to simply re-litigate facts. You must identify an "arguable error of law" or a palpable and overriding error of fact made by the lower court. If your appeal has "so little merit" that it has "no chance of success," it will likely be dismissed, even at the extension stage.
  4. Your Conduct Matters: A pattern of "unreasonable conduct," delay, or procedural misconduct can significantly prejudice your case and negatively impact the court’s willingness to grant discretionary relief like extensions. Courts are focused on the integrity of the justice process.
  5. Estate Matters Demand Promptness and Finality: Courts emphasize the need for estates to be administered "promptly and efficiently". Protracted litigation, especially if caused by a party's unreasonable actions, is viewed negatively as it depletes estate resources and denies beneficiaries finality.
Not only did Susan lose her appeal and have her application dismissed, but she was also ordered to pay the legal fees of the responding party.  In addition, Susan incurred her own legal fees.
