Formal Opinion 158.
(1975)
Interest May be Charged by Attorneys On Delinquent Accounts

The CPR Committee holds that a lawyer may properly charge interest on delinquent accounts in accordance with the law of the State of Washington, currently R.C.W. 19.52.020.

The CPR Committee is also of the opinion that a lawyer may properly charge his client up to the legal rate of interest on the client’s delinquent account, providing the client is first advised that the lawyer intends to charge a higher rate of interest on the client’s account when the same is delinquent for longer than a stated period of time and provided that the client agrees to be liable for the payment of such higher rate of interest.
