In order to vacate a default in appearing at a conference, the defaulting party must demonstrate both a reasonable excuse for the default and a potentially meritorious cause of action. The determination of whether an excuse is reasonable lies within the sound discretion of the trial court. The court may accept law office failure as a reasonable excuse where the claim is supported by a detailed and credible explanation of the default. However, law office failure should not be excused where the default results not from an isolated, inadvertent mistake, but from repeated neglect, or where allegations of law office failure are vague, conclusory, and unsubstantiated.
