If someone has handed you a document called a BOR letter and asked you to sign it, this is what you are actually signing.
What an AOR or BOR letter is
An agent of record letter, or broker of record letter, is a short signed statement from you to your insurance carrier naming who represents you on a policy. You write it, you sign it, and the carrier acts on it. It usually identifies your business, the carrier, the policy involved, and the agent or agency you are designating, with an effective date.
The two names describe the same instrument. Carriers use both, and some use only one. The older distinction is that an agent of record tends to describe a captive agent tied to a single carrier, and a broker of record tends to describe an independent broker who can place your coverage across many. For the purposes of what the document does, treat them as the same thing.
What it changes, and what it does not
This is where most of the confusion lives, so it is worth being blunt about it.
The letter changes who represents you. It does not change your insurance. Your coverage stays the same. Your limits stay the same. Your carrier stays the same. Your premium stays the same. The policy that was in force the day before is the policy in force the day after.
What moves is the servicing relationship and the commission attached to it. That commission is already inside your premium and is being paid to someone right now. When a carrier recognizes a new agent of record, it redirects that payment. The carrier’s total outlay does not change, which is why signing a letter does not cost you anything directly.
How the process actually runs
You sign the letter and it goes to the carrier. The carrier then notifies your existing agent and applies a waiting period, commonly around 5 to 10 business days, before the change takes effect.
That waiting period exists for your protection, even though it can feel like a delay. It gives the incumbent agent a chance to contact you and confirm you meant to sign. People do sign these without understanding them, and the window is what catches that. Your current agent can also waive the waiting period, which sometimes moves things along faster when everyone is in agreement.
If you sign a second letter later, the most recent one governs. Nothing is permanent, though each change restarts the clock.
When a BOR letter is the right tool
It fits one situation cleanly: you are satisfied with the policy and not satisfied with the service.
That happens more than people expect. The coverage is correct, the price is competitive, the carrier is solid, and the problem is that nobody returns calls, certificates take a week, or the person who understood your business left the agency. A BOR letter solves exactly that. It moves the account to an advisor who will service it, without disturbing coverage that is already working.
It also solves the blocked-market problem. If several agents approach the same carrier about your account, the underwriter does not know who speaks for you and may decline to quote anyone. The letter establishes who has standing.
When it is the wrong tool
If your problem is the coverage or the price, a BOR letter by itself does not fix it. It moves the advisor and leaves the policy exactly where it was. What you want in that case is a genuine market review, which may or may not follow a BOR.
Be most careful about one specific framing. If you are asked to sign a BOR letter so an agent can quote your business, ask what the letter actually does before signing. An agent generally does not need one to approach markets that are open to them. A BOR letter is for taking over a policy you already have, not for producing a quote. That is not always explained, and the person signing usually thinks they authorized a price check.
How we handle it
We receive these letters, so we will be straight about our own incentive here. We would rather you understand the document than sign it quickly.
When a BOR makes sense, we say so and we handle the letter and the waiting period. When it does not, we say that too. If what you actually need is a market review, that is a different conversation and it does not have to start with moving your account. And if you are on the other side of it, having signed something you did not fully understand, a later letter puts it back.
Questions to ask before you sign
Ask what specifically changes when you sign, and get the answer in terms of coverage, premium, and representation separately. Ask whether this is a quote request or a transfer of an in-force policy, and do not accept a blurred answer. Ask which policies the letter covers, because it can be one or all of them. Ask what the waiting period is and when it takes effect. Ask what happens to your relationship with your current agent during that window.
If the answers are vague, that is your answer. A BOR letter is a simple document, and anyone asking you to sign one should be able to explain it plainly.
