Does a certified letter delivered to Mr. and Mrs. Whom Ever Indiana Law mean both parties have been notified?

Answer 1

If someone in your household signed for it then you have constructively received it. I wouldn't spend too much of my time on trying to get the case tossed out for insufficent service unless you know the statute of limitation will expire before they can refile.

Answer 2

In some states, service on a spouse is considered service on both, but many states have held that if you are serving someone with process (that is, a summons and complaint) then you must serve each separately by certified or registered mail (restricted delivery). I can't say for Indiana specifically. The safe way is to ask the court clerk or check the Indiana rules of civil procedure.

Answer 3

It depends on who signs for it. If one of those people sign for it, that person has been served. You would need to mail items to both for both to be served AND both parties would have to sign for them.

Answer 4

Yup
