Price & Payment Information
The most common inquiry of clients is how much their case will cost. The only true answer to this question is that it depends on the facts of the case: Every client and legal matter is unique. The price in a particular case depends upon the scope and complexity of the legal work to be done, which must be assessed in an initial consultation with the attorney.
  • Initial 30 Minute Consultation By Phone or Video = $75
  • Initial 60 Minute Office Consultation = $175

The initial consultation fee is credited towards subsequent legal services (making it free for those who move ahead with legal services). The modest fee is charged to prevent abuse of the attorney's valuable time by individuals who are not seriously considering paying for legal services but just want free legal advice. Free general legal information, including answers to frequently asked questions, is provided in the online legal guides below.

Payment of legal bills can currently be made by bank wire transfer, a check drawn on a client’s U.S. bank account, or by major credit card (Visa, Mastercard, American Express and Discover).
