Several financial and legal websites offer sample letters to stop a debt collection agency, including RocketLawyer.com and TateEsq.com. These letters illustrate the process of writing a letter to instruct the collection agency to stop contacting the debtor due to one reason or another.
Rocket Lawyer displays a sample of a cease and desist letter sent to a collection agency. The reason behind the letter is to complain about harassment from the collection agency. Tate Law provides a sample of a stop collection letter in which the debtor has already had debt discharged in bankruptcy. All the samples follow the same format, starting with addresses, a reference and a body containing the reason for stopping the collection agency.
