This question cannot be answered with any certainty since often lawyers fees vary based on experience, fee type, and services contracted for. If interested please contact me direct to discuss specifics of your matter to better estimate costs if you were to retain services of our firm.
If the matter is highly contested, an experienced lawyer would likely ask for about $8000 advanced fee. My office will work with clients however, and despite my level of experience, I usually ask for 1/2 of that. the total cost will depend on what happens in your case.
