Consider accepting credit cards. The vast majority of my clients prefer to pay via credit card. LawPay is my credit card provider and I am very happy with them. LawPay takes a percentage of each charge and also charges a flat monthly fee. LawPay permits clients to pay via credit card into either a trust account or operating account. LawPay also complies with the strict California ethics rules pertaining to credit cards and trust accounts. (See State Bar Formal Opinion 2007-172, available at ethics.calbar.ca.gov/LinkClick.aspx?fileticket=ngt5WX-QswE%3D&tabid=838.)
Have clients provide credit card information up front as security in addition to, or in lieu of, a deposit. Include a clause in the fee agreement authorizing the attorney to charge the credit card only (1) if a payment is a certain number of days past due or (2) if the client otherwise consents.
