He continuously asks for an additional $5,000. It feels as if they are not documenting what they are doing but instead it seems as though he is working on what he feels has been reasonable for each $5000.
The attorney should provide an itemized bill, whether you request it or not. Your attorney may very well be working very hard on your case and documenting everything accordingly. Most times, clients don't see what goes on behind the scenes when attorneys work on a case and attorneys may spend several hours that they don't even bill for when working on a case.
That being said, if you are having problems with your attorney, you can reach out to CAAP.

Generally a lawyer needs to provide an explanation for the bill he wants his client to be paid. Some states require the fee agreement to be in writing and address issues like the one you raise about providing itemized bills.
What you owe your lawyer will typically depend on what your agreement with the lawyer was. If you have it in writing, it should spell out how your bill will be determined and how you will be billed. If it is oral, it will be more difficult to determine what is appropriate.
There is likely a service at the attorney's bar association that can help you with questions about attorney's fees. And if you have a complaint about his performance the bar association can point you in the direction of where to make that complaint.
There is no law requiring an itemized bill but it is good practice. Whether you are entitled to one depends on your agreement. Regardless, if you request one and your attorney fails or refuses to provide one, you are free to find one who will.
If you are unhappy with the service you are receiving, perhaps you should consider discharging your present attorney and hiring new counsel. There are many attorneys in your area who have posted a profile here on and who would welcome the opportunity to assist you. However, you must reach out to them (contact info available on each attorney’s profile) as attorneys are not allowed to directly solicit your business. All the best!
