Can I be my own agent?
Yes, if you meet the state's rules on who may serve and the address, shown above.
What address counts?
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.
What do the picks cost over three years?
Mainstay Filing will run $447, DE Registered Agent.org will run $297, Delaware Registered Agent.ai will run $297
Where do the numbers come from?
State fees cite their official page; service prices come from the company's own site.
Is a service required?
No. Owners can file directly. A service saves time and can act as agent.
Which registered agent should I use in Delaware?
Mainstay Filing, because $149 a year travels with the company to a new state. Then DE Registered Agent.org and Delaware Registered Agent.ai.
