Is an electronic signature valid?

Yes. Electronic signatures satisfy the ESIGN Act and UETA tests when intent, consent, attribution, and retention are present (see 15 U.S.C. §7001 and UETA). Retain an audit trail showing signer intent and capability to access the record.

Do I need a notary for the fee letter?

Usually no. Notarization is not required for routine fee letters unless a state rule, court, or specific transaction (e.g., deed, power of attorney) demands it. Use RON where permitted for remote notarization.

What if the client disputes a charge?

Follow the dispute resolution steps in the letter and your state bar fee dispute procedures. Retain all time entries, communications, and the executed fee letter to support your billing position.

Can the fee letter be amended?

Yes. Amendments should be in writing, signed by both parties, and reference the original letter and matter ID to avoid confusion about effective dates and changed terms.

How long must I keep the executed letter?

Retain for the life of the matter plus applicable retention periods. Federal guidance: keep tax-related records for at least 3 years (IRC §6501(a)); HIPAA-related records for 6 years (45 CFR §164.530(j)).

How should I store electronic copies?

Use secure, access-controlled storage with encrypted transport and at-rest encryption (TLS and AES-256). Ensure exportable audit logs are retained for evidentiary needs.

What this letter is and when it’s used

A Letter Regarding Attorney-Client Fee Contract is a formal written communication used to confirm, explain, or modify the fee arrangement between an attorney and a client. It typically summarizes the agreed billing method (hourly, flat, contingency, retainer), payment terms, scope of services, and any contingencies such as additional costs or termination conditions. The letter creates a clear record that both parties can rely on for billing, ethical compliance, and dispute avoidance, and it may be attached to or incorporated into the underlying engagement agreement.

Why a clear fee letter matters to both parties

A concise fee letter reduces misunderstandings about billing, supports informed consent under ethical rules, and documents expectations for dispute resolution, retainer handling, and termination. It benefits attorneys by establishing enforceable payment terms and benefits clients by providing transparency on costs and responsibilities.

Who prepares and who receives this letter

Use the letter to create a contemporaneous record that supports billing, compliance, and any future accounting or audit requests.

Individual clients who retain counsel for discrete matters such as family law, estate planning, or litigation
Corporate clients or in-house counsels managing outside counsel engagements and budgets
Third-party payors or insurers when fee arrangements are conditional on reimbursement or assignment

Signed parties and authorities

Client — Individual

A named natural person or authorized representative who agreed to retain counsel. The text should identify capacity (e.g., trustee, guardian) and include contact and billing details. Signature by an agent requires proof of authority.

Attorney / Firm

The responsible attorney or an authorized billing officer signs for the firm. Include firm name, bar number where relevant, billing contact, and any escrow or trust account instructions for retainer handling.

Core elements to include in the fee letter

A professionally drafted fee letter organizes the agreement so each key topic is explicit and easy to reference for billing, client questions, and potential audits.

Scope of Services

Describe discrete tasks or matter scope; avoid open-ended phrases. Specify deliverables, excluded matters, and whether additional work requires separate authorization or a new engagement.

Billing Method

State hourly rates by attorney or role, flat fees, contingency percentages, or blended rates; explain how rate changes will be handled and provide examples of time increments.

Retainer and Trust Handling

Specify retainer amount, whether it is refundable, how it will be applied to invoices, and trust accounting procedures consistent with state bar rules.

Expenses and Disbursements

List reimbursable costs (filing fees, expert witness fees, courier, deposition transcripts) and whether they are advanced by the firm or billed as incurred.

Payment Terms

Set invoice frequency, due dates, interest or late fee policy, and accepted payment methods. State consequences for nonpayment, including engagement suspension or withdrawal.

Dispute Resolution

Note any fee arbitration clauses, governing law, and contact point for contesting charges; reference client’s right under state fee dispute procedures where applicable.

Practical tips for clear, enforceable fee letters

Adopt these drafting and administrative practices to reduce disputes and support ethical compliance while minimizing administrative overhead.

Use plain, specific language

Avoid legalese that obscures billing mechanics; set out concrete examples of billed activities and how time will be recorded.

Document client consent to electronic delivery

For consumer-facing matters, include ESIGN consumer disclosure and confirm the client can access electronic records per 15 U.S.C. §7001(c).

Maintain an auditable trail

Capture timestamps, signer identity, and communication history so invoices and retainer accounting are defensible in audits or disputes.

Review periodically for consistency

Update templates when rates, state rules, or firm policies change to ensure new letters reflect current practice.
