When you hire an attorney, one of the first things they may ask for is a retainer. Many people pay one without fully understanding what it is, how it works, or what happens to unused funds. This guide explains attorney retainers clearly so you can make an informed decision.

What Is a Retainer Fee?

A retainer is an upfront payment you make to an attorney before they begin working on your matter. Think of it as a deposit that the attorney holds in a client trust account and draws from as they bill hours to your case.

The retainer itself is not the attorney’s fee. It is a fund that gets used up as work is performed. As the attorney works on your case, they apply their hourly rate against the retainer balance. When the balance runs low, they may ask you to replenish it.

Types of Retainers

Classic (Evergreen) Retainer

The most common type. You pay an upfront deposit, the attorney draws from it as they work, and you replenish it when it runs low. At the end of the matter, any unused balance is refunded to you.

Flat Fee Retainer

For defined, predictable tasks (drafting a will, forming an LLC, an uncontested divorce), some attorneys charge a flat fee upfront. Unlike the classic retainer, this amount is typically non-refundable once work begins because the scope is fixed.

General Retainer

Less common in consumer legal matters, a general retainer pays to reserve the attorney’s availability for a period of time, regardless of how much work is actually done. This is more typical in ongoing business relationships.

What Happens to Unused Retainer Funds?

Under attorney ethics rules in most states, retainer funds must be held in a client trust account (IOLTA account) separate from the attorney’s own funds. When the matter concludes, any unused balance must be returned to you. Ask about this upfront and confirm it is in your fee agreement.

Is a Retainer Required?

Not always. Many attorneys offer:

  • Flat fee arrangements with no retainer
  • Contingency fee arrangements where you pay nothing upfront (common in personal injury)
  • Payment plans for certain matters

If a retainer is required, the amount varies widely depending on the complexity of the matter and the attorney’s hourly rate. Always ask what the retainer covers and when you will receive your first bill.

Questions to Ask About a Retainer Before You Pay

  • What is your hourly rate, and who else will bill time on my matter?
  • Will the retainer be held in a client trust account?
  • How often will I receive invoices?
  • What happens to unused funds when the matter is resolved?
  • What triggers a replenishment request, and how much notice will I get?
  • Is there a flat fee alternative for my type of matter?
