Did you have a question?
Talk to the lawyer him/herself, not the front desk clerk or billing person.
What does your representation agreement with this attorney say regarding fees--in particular if a court filing is required? The rates you mention are not outside the bandwidth of acceptability.
Many states have a Fee Dispute Resolution process set--see if your state does if you believe the fees excessive.
FWIW, the time to question fees is maximized if its executed before a representation agreement is signed--your rights diminish significantly, but not altogether, after signing.
NOT LEGAL ADVICE. FOR EDUCATION AND INFORMATION ONLY. Mr. Rafter is licensed to practice before the state and federal courts in Virginia. There is no implied or actual attorney-client relationship arising from this education exchange. You should speak with an attorney licensed in your state, to whom you have provided all the facts before you take steps that may impact your legal rights. Mr. Rafter is under no obligation to answer subsequent emails or phone calls related to this matter.
I think that you should meet face-to-face with your attorney to discuss this matter. You should not be speaking only with his assistant. This all may be misunderstanding. Remember that a problem with hiring another lawyer is that you will incur additional legal expense. You should also determine if your state has a method of resolving attorney fee disputes. I am not a Kansas lawyer and did not offer this as legal at advice.
Have you signed the final accounting settlement which this amount of $10,000 less?
This answer is predicated on the facts provided in which the lawyer cannot confirm or verify. I do not represent you as we do not have an attorney-client relationship.
