The Legal Services Retainer Agreement is a contract between the attorney (or law firm) and the client (or corporation) for the legal representation before governmental agencies and it provides identity to the client. Attorneys fees can be fixed, hourly, sometimes with or without a retainer, or they can be contingent upon whether the case is won or lost. Also to be taken into consideration should be out of pocket expenses such as filing fees, court disbursements, photocopy costs, telephone expenses, postage, travel, storage, office supplies, and miscellaneous expenses.
There is no legal requirement that a lawyer charge a client a set fee or a percentage of money recovered in a case, even though most will claim (33&1/3%). You, the client, have the right to talk with your attorney about the proposed fee and to bargain about the rate or percentage as in any other contract. If you do not reach an agreement, you may talk with other attorneys and be sure to get everything in writing.
