This is a very difficult question, and the answer will vary depending upon the exact circumstances. Nevertheless, you should understand that you have no legal obligation to do so, and in many cases it will not be to your advantage. It is also possible to negotiate the nature of the extension, both as to length and scope.
Thank you for your good work in resolving my innocent spouse case. I will be forever grateful!
It is a pleasure to send you this check...knowing I have friends like you who are there to help!
Words can not express my appreciation. YOU DID IT!!!! I have dealt with and paid multiple people to resolve my tax problems, however you were the only one who was successful...
Your assistance is greatly appreciated and beyond the call of the average attorney who would not take the time. I will consult with you and refer whomever I can to you, whenever possible.
