Thank you for your reply.
The Rules of Professional Conduct, which cover this type of thing, do not have a specific time limit, it simply says the attorney should act within a reasonable time. What is reasonable is going to be based on how busy his practice is and the nature of your issue that he is dealing with. Based on what you stated above 30-45 days would be a reasonable time for him to have at least sent out letters to the dealer and Wells Fargo and Warranty company to try to get the proper amount credited to you. The attorney is supposed to also communicate with you reasonably when they have information on your case.
If the attorney is doing neither, as you are approaching 45 days, you need to send the attorney a letter informing him that it has been more than 30 days since you asked him for assistance and as of this time he has not provided any information on action he has taken. In the letter you need to ask him to inform you on his actions and if he has taken none and is not able to do so to return any money you paid him immediately so you can go elsewhere.
At that point, if the attorney does not respond, you need to file a complaint to the state bar against him and you need to consider getting a new attorney involved to handle the matter and get your matter moving and seek a refund of any fees from the first attorney through the bar association fee dispute mediation
if the attorney does not voluntarily refund your money.
He should have had letters sent to everyone within at least 45 days though as that does not take long to get done, even though replies from each party may take more time than that and it is out of his control.
