BOR letter (broker of record)
A broker of record (BOR) letter is a document signed by the insured that names a new agent or broker as their representative with a carrier. Once the carrier accepts it, the new agency takes over servicing the account and, in most cases, the commission. The policy itself does not change.
How the process works
The insured signs a letter, typically on their own letterhead, naming the new broker of record for specific policies or carriers. The new agency delivers it to the carrier. Most carriers then apply a waiting period before the change takes effect, during which the incumbent agent is notified and the insured can rescind by signing a counter letter. The exact rules and timelines vary by carrier.
That rescind window exists for a reason. BOR fights are common, and carriers want proof the insured actually intends to move before they reroute commission.
Why it matters to agencies
A BOR is how commercial accounts change agencies without changing carriers. There is no remarketing, no new applications, no new underwriting. Same policy, same carrier, new agent. That makes it the fastest way to win an account, and the most painful way to lose one, because the revenue leaves while the coverage stays put.
The defense against losing accounts to BOR letters is unglamorous: responsive service and a documented record of the work you do. Accounts rarely sign a BOR for an agency they hear from all year.
Common questions
Can a BOR letter be reversed?
During the carrier's waiting period, yes. The insured can rescind by signing a letter reinstating the incumbent agent. After the change takes effect, the account belongs to the new broker and moving it back requires a new BOR letter.
Does a BOR letter change the client's coverage?
No. The carrier, policy, terms, and premium all stay the same. Only the servicing agent and the commission routing change.
