More boxes to open

Can I be my own agent?

Yes, if you meet the state's rules on who may serve and on the address, both shown above.

What address does an agent need?

The address has to be a street address in New Mexico. P.O. boxes are not accepted.

What do the picks cost over three years?

NM Registered Agent.org stacks up to $297, Mainstay Filing stacks up to $447, New Mexico Registered Agent.co stacks up to $297

What do these numbers rest on?

The state-side figures were taken from New Mexico's own publications, and the service prices from the price page each company posts. Dates for both appear on this page.

Do I have to use a service?

No. Owners can file with the state directly. A service saves time and can act as agent, but nothing makes you hire one.

Who tops the stack in New Mexico?

NM Registered Agent.org, because its service puts a street address on file for $99 a year. Then Mainstay Filing and New Mexico Registered Agent.co.
