Different divorce lawyers require different retainer deposits for their services. Retainer deposits are money that is placed into a client trust account (called an IOLTA), and when the attorney earns those funds he or she can place them into their own business account. The retainer deposit may or may not cover the entire cost of a case. Be careful of an attorney that requires a very low retainer deposit – if the deposit seems low to you, your instincts are probably right. Look for an honest, straightforward discussion about the overall cost of your case.
