Legal Question in Family Law in California

Without knowing more than one instance it is difficult to determine. The totality of the circumstances needs to be considered but generally if you're represented by counsel the court should not proceed without them.

Although they could default you for the hearing so the court may have been willing to proceed with you instead of simply ignoring you. There are so many factors to consider. There is nothing to require the court must wait to proceed until the attorney or party arrives although they usually do as a courtesy.

The big issue right now is damage control. That means you need to either articulate what the result of the hearing was, or determine whether something adverse to your position has happened as a result of your attorney's failure to appear and the court going forward with the case in your attorney's absence. Your post is devoid of any information as to what was the result, and whether it adversely affected you legally.
