The way to dispute attorney fees

I will give you what you need to know and need to do to  dispute attorney fees,  i believe that will be very useful for you:
First, You start by chatting with your lawyer and explaining your concerns. See if you can work something out. If you cannot, the next step varies based on your fee agreement and where you are located. In some states there is a mandatory fee dispute program and you will be required to use that. In other states there is an optional fee dispute program, and you can choose to try to use that. If your fee agreement spells out the dispute process, you need to begin by following that. Assuming none of these are available or they have not worked (and they are not the final step in your state or under your agreement) you can sue.

Keep in mind, losing is not a basis to dispute fees. Attorneys are entitled to their fees unless those fees are objectively unreasonable based on the work performed or you can show some sort of problem such as fraud related to the fees, double billing, something along those lines.

 Additionally, The first step is to have a chat with the partner or senior lawyer in charge of your account. Explain why you think the fees are too high, or undeserved, or not as promised, the services were not rendered properly, or you cannot afford them. If you want to work with them going forward it helps if you're open to a productive outcome, like paying a lower amount immediately and agreeing on how to avoid any misunderstandings in the future.

If that doesn't work, you should look carefully at any engagement agreement, and exchange of emails or other messages to see what you and they agreed to, and if there's any procedure specified there for resolving fee disputes. Depending on which state (or country, if outside the US) you are in, the bar rules require lawyers to submit to a fee arbitration process on demand of the client, so consider that dispute process. Alternately, unless your engagement agreement requires arbitration you can go to court over the fees, but that's usually a last resort. If the lawyer is being truly unreasonable you can file a complaint with the state bar, or tell them you are going to unless you work out a fee arrangement.
