Ask the Home Insurance Expert
How can I found which insurance company insures my house if I have no papers or records?
This is something one really needs to keep track of. There's no way to find out who insures your house if you don't know, except to wait for the next premium bill and see who it's from.
Do you have an insurance agent? He would know.
If not, your best bet is to try to remember who you wrote your last insurance check to.
