Doubling down on LaSalle v. Vogel (2019) 36 Cal.App.5th 127, this decision holds that plaintiff’s counsel owes an ethical and legal obligation to notify the defendant’s counsel (if known) of the defendant’s failure to timely respond to the complaint and plaintiff’s intention to seek a default.  Here, plaintiff not only didn’t notify defendant’s counsel, but also arranged to serve the complaint and the notice of entry of default on an ordinary employee after 5 pm on the Friday before Thanksgiving–a manner calculated to minimize the chance of actual notice.  In addition, plaintiff would suffer no prejudice from setting aside the default, and defendant acted with reasonable promptness in seeking relief from default.  For each of those reasons, the trial court abused its discretion in failing to grant relief from default and the ensuing default judgment.
