Benefits, Ethics, and Implementation Guidance for Ohio Law Firms

Lawyers can make billing more predictable by using evergreen retainers, which maintain a consistent trust balance and reduce accounts receivable.

This piece is part of a series discussing fee agreements and billing practices. In prior articles, we covered fee types, retainers, alternative fee models, fee agreement upgrades, and how to ethically apply funds associated with one matter to a different matter. This week we address in greater depth the benefits and practical implementation of evergreen retainers. 

A Proactive Approach to Billing

While lawyers consider alternative approaches, hourly billing remains the most dominant form of law firm billing.[1] In an hourly billing practice, attorneys must be vigilant when addressing retainer replenishments, trial retainers, and anticipated fees relative to the status of the matter. Billing challenges arise when billing expectations and account balances are misaligned – invoices are outstanding, multiple follow-ups are required, and receivables begin to age. This creates uncertainty for the firm and discomfort for the client.

Evergreen retainers take a different approach. By maintaining a client trust balance that is replenished as work is performed, firms reduce accounts receivable, create a more predictable billing process, and avoid high retainer replenishment demands.

The result is improved cash flow and a more stable relationship between lawyer and client.

How Evergreen Retainers Work

An evergreen retainer is a stable advance fee deposit held in trust and applied to legal expenses. The client agrees to maintain a minimum trust account balance and as fees are earned and billed, the retainer is replenished.

For example, a client maintains a $5,000 retainer. If $1,500 is earned and transferred at month’s end, the client replenishes the trust account by $1,500 to restore the agreed balance.

A variation is a recurring contribution approach, where the client makes regular payments to maintain the trust balance, up to a defined maximum. For example, a client may begin representation with a $1,500 retainer and agree to make $250 biweekly payments, with the trust balance not to exceed $5,000.

In all situations, in accordance with Ohio Professional Conduct R. 1.15, funds remain in the trust account until earned and are transferred to the operating account as work is completed. The structure is straightforward, but the consistency it creates is significant.

Benefits for the Lawyer–Client Relationship

Evergreen retainers reduce some of the most common sources of friction in legal practice: unexpected payment demands, unpaid balances, and inadequate retainer balances.

For clients, the arrangement provides predictability and avoids large, unexpected bills. For lawyers, it reduces the need to follow up on outstanding balances or address accounts in arrears.

Keeping accounts current allows both parties to focus on the work, not the status of payment.

Ethical Alignment

Evergreen and recurring contribution retainers align with Ohio’s Rules of Professional Conduct when structured properly.

Advance fees must be held in trust and remain client property until earned under Rule 1.15. Rule 1.5 requires that the fee structure be communicated in a manner the client can understand. For recurring contributions, this includes clearly explaining the timing, amount, and maximum balance of payments.

If a firm processes recurring payments, the client’s informed consent is essential. The engagement agreement should specify the client’s authorization for those payments, the method by which they will be processed, and the client’s right to modify or terminate the arrangement. And don’t forget – if recurring payments are made via credit card, specify how credit card fees will be handled. Transparency around how and when funds are earned, applied, and replenished is critical.

When expectations are clearly defined and consistently followed, both traditional evergreen retainers and recurring contribution models support ethical compliance and sound financial management.

Sample Engagement Language

The following are examples of how evergreen retainer arrangements may be described in a representation agreement:

Option 1 – Evergreen (Minimum Balance) Retainer

Client agrees to provide an advance fee deposit of $___, which will be held in the firm’s trust account and applied to fees and expenses as they are earned. Client agrees to maintain a minimum balance of $___ in the trust account. The firm will bill for services on a monthly basis and will transfer earned fees from the trust account to the operating account.

If the trust account balance falls below the agreed minimum, Client agrees to replenish the account within ___ days of notice. Any unearned funds will be returned to Client at the conclusion of the representation.

Option 2 – Recurring Contribution Variation

Client agrees to provide an initial advance fee deposit of $___, to be held in the firm’s trust account and applied to fees and expenses as they are earned. Client further authorizes the firm to process recurring payments of $____ on a [weekly/biweekly/monthly] basis to replenish the trust account, up to a maximum balance of $____.

Client understands that all funds will remain in the trust account until earned and that the firm will bill regularly and transfer earned fees accordingly. Client may modify or terminate the recurring payment authorization upon written notice to the firm. Any unearned funds will be returned to Client at the conclusion of the representation.

Best Practices Strengthen Your Practice

Evergreen retainers and recurring contribution models offer a practical way to reduce accounts receivable, improve predictability, and stabilize the billing relationship between lawyer and client.

Effective implementation depends on clarity and consistency. Firms should define the structure of the retainer (including minimum balances, replenishment timing, or recurring payment terms) and communicate those expectations at the outset of representation. Regular billing and prompt application of earned fees help ensure both the firm and the client understand the status of the account at all times.

For recurring contribution models, clear client authorization and an understanding of the client’s right to modify or terminate payments are essential. Firms should ensure that payment processes are transparent and consistently applied.

These approaches work best when they are treated not as exceptions, but as standard practice. When accounts remain current, lawyers avoid the need to follow up on unpaid invoices, and clients benefit from predictable, manageable payments. The result is a more stable and professional financial relationship.

Sound billing practices do more than improve cash flow: they reinforce trust.
