I will be starting with a new firm shortly and the start date is firm.  I know I'll be filling out my U-4 with the new company on the first day.  The problem is that my current company will owe me some sizable commissions on life/annuity business and I believe I need to be "employed" at the time the policies get issued/paid.  My guess is that they will cross by 2-3 days at most.  The new job only handles investments and I will not be doing ANY insurance work.  Also, the existing company lets you go the day you give them a 2-week notice.

A few questions:

Am I legally responsible for resigning from the old firm prior to starting with the new firm?  I won't be conducting any business during this 2-3 day overlap.   How soon after I sign the U-4 with the new firm does the old firm get notice? Does anyone have any other input/recommendations that I haven't addressed?

The commission is enough to make this gray area something I need to address, otherwise I would just walk.  Thanks in advance for your help!!
