In order to vacate a default in opposing a motion pursuant to CPLR 5015(a)(1), the moving party is required to demonstrate a reasonable excuse for the default and a potentially meritorious opposition to the motion. The determination of what constitutes a reasonable excuse lies within the sound discretion of the Supreme Court. Ignorance of the law, failure to retain an attorney, and confusion about the date of a conference do not constitute reasonable excuses.
