A defendant seeking to vacate a default in answering or appearing pursuant to CPLR 5015(a)(1) must demonstrate a reasonable excuse for the default and a potentially meritorious defense to the action. The determination of what constitutes a reasonable excuse lies within the sound discretion of the Supreme Court. In determining whether there is a reasonable excuse, a court should consider all the relevant factors, including the extent of the delay, prejudice to the opposing party, whether the default was willful, and the strong public policy in favor of resolving cases on the merits.
Here, the defendant's excuse that he believed that the attorney representing him in separate litigation was addressing this action was unreasonable. Mere neglect is not a reasonable excuse. Likewise, his conclusory and unsubstantiated claim that he was hampered by the restrictions imposed in response to the COVID-19 pandemic does not amount to a reasonable excuse.
