Address for where to send a Death Certificate?

Sorry for the late reply, and please accept our sincerest condolences on your loss. 

In terms of the account itself, once an account is moved over to the estate of, it'd be immediately cancelled in our system. If you want to keep the service active, it'd need to be moved under a different name for the time being until you decide what to ultimately do with it (move it, cancel it, etc.)

So the best course of action may be to keep it open and pay for it until you're ready to cancel/move it to a different account. There's no immediate decision on this that needs to be made either. We know how hard it is to deal with estate matters among everything else going on.
