You could, but it probably won’t help the situation.
When you’re overwhelmed with debt, it’s common to get creditor calls, a lot of creditor calls.  Calls from creditors are miserable.  Like most people, you just want the calls to stop. 
Unfortunately, telling your creditors that you are planning to declare bankruptcy is unlikely to do the trick and unlikely to make creditor calls stop. The creditors can and will continue to call.  If you retain our Arizona bankruptcy attorney, our attorney and staff will take all of your creditor calls and make it so you won’t have to talk to your creditors any longer.
