If your principal is alleging that you are in repudiatory breach, it is not obliged to give you any notice of termination.  If your principal is not alleging repudiatory breach, the notice required to be given will be dependent on the length of the agency.  For any agency which has lasted for three years or more, you must be given three months’ notice of the termination of your agency.  If the agency has lasted for two years then you should be given two months’ notice and one year, one months’ notice etc.  However, if you have a written agency agreement in place which provides that you should be given a longer notice period than three months’, it is likely that this longer period would apply.
