Fees are not uniform.  They reflect the circumstances of the matter under consideration: complexity, time commitment, number of parties, potential for impact on other obligations, amount involved, and other relevant circumstances of the parties, counsel, and the matter.   For Mediations:  Fees are usually a set daily session rate, per party.  An approximate median guideline number is $2,500.  This daily session rate also compensates for conference rooms, food service at the mediation sessions, and, most importantly, for preparation time and follow-up, which, for my approach to mediation, are usually considerable time investments.   For Arbitrations:  Good working guideline median numbers are $450 per hour for work before and after the hearing and a daily hearing rate of $4,000.   Fixed Fee Arrangements:  Can often be attractive to the parties and workable.   Expenses:  When the matter calls for work outside Houston, travel and lodging expenses will be allocated pro-rata and charged to the parties.
