My partner had a divorce
petition served at his mother's house. His ex simply
stated somewhere on the petition that she didn't know his current
whereabouts, but that his mother lived at X address.
Don't
know what happens if he then doesn't return the
acknowledgement of service, but at least
it's a start???
Oh the other thing is that if your husband happy
with going ahead with a divorce, but just doesn't want to give you his home
address, if he appoints legal representation, I think you can give the law
firm's address as the address for service.
Of course, you'll
want to check all of these suggestions with somebody legal. Hopefully one
of the lawyers on here will be able to give you an answer from a legal
perspective, rather than just a bit of personal experience...
