Texas Ethics Opinion No. 577, issued in March 2007 and published in the October 2007 Texas Bar Journal, addresses when and how a law firm can charge a client more for an attorney’s services than it pays the attorney. The opinion notes that Texas Disciplinary Rule of Professional Conduct 1.04(f) governs the division of fees between “lawyers who are not in the same firm.” When a firm or lawyer charges its client more than it pays a lawyer outside the firm, the opinion considers this a division of fees subject to Rule 1.04(f).
