Delaware registered agent requirements, as written by the state (Delaware Secretary of State)
Every LLC must name a registered agent with an in-state street address.
The LLC itself, a Delaware resident, or a business entity formed in Delaware or authorized to do business there. (6 Del. C. § 18-104)
The address has to be a registered office in Delaware. An entity agent keeps a business office there that is generally open; an individual agent has to be generally present there. A virtual office or mail-forwarding service alone does not qualify.
