If you are engaged as an Insurance Broker operating in Maryland, you are required by the Maryland Insurance Administration to file a Maryland Insurance Broker Bond as a condition of licensure.
Bonds Express offers a Maryland Insurance Broker Bond with a 99% approval rate

A surety bond protects the party requesting the bond, the Obligee, against any financial losses as a result of poor financial decisions, damages, unethical decisions, or a failure to follow state and local laws on the part of you, the Principal. The Maryland Insurance Broker Bond holds you accountable for your business decisions. 

By possessing a Maryland Insurance Broker Bond, you are telling your Obligee that you can be trusted as a Principal and that you stand behind your business decisions.
