Yes, for the most part. As soon as you file a bankruptcy petition, Section 362 of the United States Bankruptcy Code prohibits creditors from taking most actions to collect a pre-petition debt. This is called the Automatic Stay, and prohibits most calls from creditors. If you hire my office, I will allow you to give the creditor my office phone number, and you can then instruct creditors that you are represented and they need to call your attorney.
