I have come home to an emptied house....What next?

[Awoken]

Should I change the locks to the house?

Uh, did you read the earlier posts?

I don't think you should change the locks, at least until you see a lawyer.

It sounds like you are in a panic and want to take some kind of action, and take it now. (I'm guessing of course!)

If you have to do something, then do something just for yourself, something that has nothing to do with your wife and the situation.
