You can fire your old lawyer and may not have to pay the full 1/3 fee, depending on the amount, quality of his or her work, and depending on how your old lawyer originally obtained your case.
If your old lawyer handled your case appropriately, and obtained your case appropriately, you will have to pay his or her 1/3 fee. In most instances, a difference in opinion about the value of your case is not a justification for firing your lawyer.
You are going to need a skilled attorney to evaluate this case. The vast majority of wrongful death cases are worth way more than 50k. But there may be issues with the case that would lower (or raise) the settlement amount.
It adds to the value of the case significantly, assuming the disability is related to the accident. Assuming you have a competent attorney who finds the right expert witnesses for your case, and develops the facts of the case appropriately, your husband's disability should be included as a large part of any settlement.
I'd be happy to discuss this with you in more detail if you want.
I would suggest you contact a Board Certified Personal Injury lawyer with experience winning 18-wheeler cases. Very important that you not only get a lawyer on your side but also that you get a lawyer with a history and reputation winning 18-wheeler cases.
Here are some resources you may want to look at that should be helpful to you:
You need a lawyer, and here's why: The insurance adjuster for the responsible party has no doubt already done whatever they can do to hurt any chance you have of recovering for your injuries.
Or, if the accident was your fault, then you probably need a comp lawyer to ensure you get the comp you are owed.
