Usually legal action against a person or business involves serving them with registered mail. What exactly is considered an acceptable address of service? I understand that if a legal proceeding has already started and if the person or business moves to a new address without updating their information with the court/plaintiff, their old address is still considered their address of service (in short, they don't escape by not providing a new address). Also, it's not illegal for someone to lie.
For example, if Joe tells Bob he will pay him $500 for some work. Joe tells Bob his address but lies about it. If Bob does the work and Joe doesn't pay him, can Joe fill in court against Bob using the provide (false) address and the court would still consider Joe to have been served?
Basically I'm asking, does a party need to be reasonably certain an address for a defendant is in fact their address and not just a lie?
