If your upline denies your release request, you will need to contact the carriers you are contracted with to see their policies. Most will make you wait six months to get released without the approval of your upline. During this time, you may not be able to write new business, depending on the carrier’s policies.
Email the carrier a Notice of Intent that clearly states your intent to switch your upline. Include all pertinent information, including the names of both FMOs, your name, your agent number, and whether downline agents are included. See if the carrier has a standard form to use.
