A retainer agreement is a written contract between a client and a lawyer that spells out what work the lawyer will do, how the lawyer will be paid, and what each side is responsible for.

In everyday use, it is the roadmap for the attorney-client relationship. It may cover an hourly fee, a flat fee, or a contingency fee, where the lawyer gets paid only if money is recovered. In an injury case, the agreement often explains the percentage the lawyer takes from a settlement or verdict, whether case costs are deducted before or after that fee is calculated, and who pays for records, filing fees, experts, or medical liens. It can also say whether the lawyer handles settlement only or will file a lawsuit if the claim does not resolve.

For an injury claim, the fine print matters because it directly affects how much of the final payout the injured person actually receives. A client who signs without checking the fee percentage, expense language, or termination terms can be surprised when deductions are taken from the recovery.

In Arkansas, contingent fee agreements must be in writing under Arkansas Rule of Professional Conduct 1.5(c). That written agreement must state how the fee is figured and what expenses will be deducted. In a state where many claims start with an insurance settlement demand, that paperwork can shape the entire claim from the first offer to the final check.
