Retainer Agreement Intake: What Every Engagement Letter Needs Before You Sign It

Three months into a breach-of-contract case, your client calls to say she never agreed to hourly billing. She thought the fee was a flat $5,000. You pull up the retainer agreement and find a paragraph that says "hourly rate of $350 per hour, with an initial retainer deposit of $5,000." She read "$5,000" and stopped reading. Now you have a fee dispute layered on top of the case you were hired to handle, and your malpractice carrier is about to get a phone call.

This is not a hypothetical. Fee disputes are one of the most common complaints filed against attorneys with state disciplinary authorities, and the overwhelming majority of them trace back to the same root cause: a retainer agreement that was drafted without capturing enough information at intake. The lawyer assumed the client understood the billing arrangement. The client assumed something different. Nobody documented the conversation where they thought they agreed.

A retainer agreement intake form is not a substitute for the engagement letter itself. It is the document that gathers every piece of information you need to draft a retainer that is clear, complete, and enforceable — one that protects both you and the client from the ambiguity that breeds disputes. Every practice area needs one. Whether you handle commercial litigation, family law, personal injury, immigration, estate planning, or criminal defense, the retainer is where the attorney-client relationship is defined in writing. Getting it wrong is not a billing problem. It is an ethics problem.

Who is the client? The question that sounds simple until it isn't.

Before you write a single word about fees, you need to establish exactly who you represent. This sounds obvious. It is not. A husband walks in to discuss a business dispute involving his wife's LLC. A corporate officer wants you to handle a contract matter but the contract is between two affiliates. A family member calls about a parent's estate but three siblings have competing interests in the outcome. If your retainer names the wrong party — or fails to specify — you may end up in a situation where the person paying your bills is not the person you owe duties to, and the person you owe duties to does not know they are your client.

Your intake should capture:

• Individual vs. entity — are you representing the person sitting in front of you, their business, or both? If the client is an entity, what type (corporation, LLC, partnership, sole proprietorship)? Record the full legal name of the entity, state of formation, and principal place of business.
• Authorized contact — if the client is an entity, who within the organization has authority to direct the engagement, receive privileged communications, and approve settlements or strategic decisions? Get a name, title, phone number, and email. This person is your point of contact for the duration of the matter.
• Additional authorized contacts — does the client want a co-counsel, in-house counsel, spouse, business partner, or accountant copied on correspondence? List them. Specify what they are authorized to receive — billing statements, case updates, privileged communications, or all of the above.
• Company name (if applicable) — even when the client is an individual, there may be a business entity connected to the matter. Capture it at intake so the retainer reflects the actual relationship.

Failing to define the client precisely has real consequences. If your retainer says "Client: John Smith" but you are actually representing Smith Enterprises LLC, any privilege claim may be challenged, your conflict check was run against the wrong name, and your malpractice policy may not cover the entity's claims. Document it right the first time.

Scope of representation: the fence that prevents scope creep

Scope creep is the silent killer of law firm profitability. A client hires you to review a lease. Then they ask you to negotiate it. Then they want you to handle a dispute with the landlord. Then they assume you are their general counsel. None of this was in the retainer. You did the work because you did not want to lose the client, and now you have billed 40 hours that the client considers outside the engagement they agreed to.

Your intake form should force you to define the scope of representation with enough specificity that both parties know where the engagement begins and ends:

• Matter description — a plain-language description of the legal matter you are being retained to handle. "Breach of contract claim against ABC Corp arising from the July 2025 supply agreement" is a scope. "Legal services" is not.
• Practice area — identify the area of law. This matters for conflict checks, for staffing, and for determining whether the matter is within your competence under the Rules of Professional Conduct.
• Included services — what specifically does this engagement cover? Drafting and filing a complaint, discovery, depositions, trial, appeal? Or just a demand letter and settlement negotiation? List what is in.
• Excluded services — equally important. If the retainer covers litigation but not appeals, say so. If it covers the contract dispute but not the related tax consequences, say so. The exclusions section is where you prevent the scope creep that destroys margins and creates grievances.
• Milestone or phase-based engagement — some matters are better structured in phases. Phase one: investigation and demand letter. Phase two: filing suit (subject to a separate engagement or fee agreement). Capture whether the client has agreed to a phased approach.

Fee structure: the part that generates the most complaints

The fee arrangement is not something you figure out after the consultation and then put in the retainer. It is something you discuss at intake, confirm the client understands, and document before anyone signs anything. State rules of professional conduct in virtually every jurisdiction require that fee agreements be clear and communicated to the client. Many jurisdictions require them in writing. All of them require that the client understand what they are agreeing to.

Your intake should capture the specific fee arrangement, and it should capture the client's acknowledgment that they understand it:

• Hourly billing — hourly rate for each attorney and paralegal who will work on the matter. Billing increment (tenths of an hour, quarter-hour, or some other unit). Whether rates are subject to annual adjustment, and if so, when and by how much. Whether the client will be billed for travel time, and at what rate.
• Flat fee — the total flat fee for the defined scope of work. Whether the flat fee is earned upon receipt or earned as work is performed (this distinction has trust account implications in many jurisdictions). What happens if the matter resolves early or if additional work becomes necessary beyond the flat-fee scope.
• Contingency fee — the percentage. Whether the percentage applies to gross recovery or net recovery (after costs). Whether the percentage changes depending on the stage at which the matter resolves (pre-suit, post-filing, post-discovery, trial, appeal). What costs the client remains responsible for regardless of outcome. Contingency fee arrangements have specific disclosure requirements in most jurisdictions — your intake should flag the matter as contingency so the retainer includes the required disclosures.
• Hybrid arrangements — reduced hourly rate plus a smaller contingency percentage. Monthly retainer fee for ongoing availability plus hourly billing for active matters. Flat fee for the transactional work plus hourly for any disputes that arise. Capture the structure precisely.
• Fee caps or estimates — has the client asked for a fee cap or a not-to-exceed amount? Have you provided an estimate? Document both, and be explicit about whether the cap is binding or the estimate is just a projection.

Retainer deposit and trust account handling

The word "retainer" is used loosely by clients and attorneys alike, and the ambiguity gets people in trouble. An advance payment retainer (money deposited into the trust account and drawn against as fees are earned) is not the same as a general retainer (a fee paid for the lawyer's availability, earned upon receipt). Your intake needs to determine which one you are dealing with and document the terms clearly.

• Retainer deposit amount — how much is the client depositing? Is this a required minimum before work begins?
• Trust account vs. operating account — where does the deposit go initially? Under the ethics rules of every U.S. jurisdiction, advance payment retainers must be held in the attorney's IOLTA or trust account until earned. Money that is earned upon receipt — a true general retainer — can go directly to the operating account, but only if the retainer explicitly says so and the client consents.
• Draw-down terms — how and when will funds be transferred from trust to operating? Upon issuance of a monthly invoice? Upon completion of each task? Your intake should capture the agreed-upon trigger.
• Replenishment obligation — does the client agree to replenish the retainer when it falls below a specified threshold? What is that threshold? What happens if the client does not replenish — can you suspend work, withdraw from the representation, or both?
• Refund of unused funds — at the conclusion of the matter, any unearned funds in trust must be returned to the client. This is not optional. Your retainer should say so, and your intake should confirm that the client understands this.

Trust account mishandling is the number-one cause of attorney discipline in the United States. It is not close. Getting the trust account terms right at intake is not a billing preference — it is a license-preservation measure.

Billing frequency and expense reimbursement

Billing practices that seem obvious to attorneys are frequently opaque to clients. Your intake should nail down:

• Billing cycle — monthly, quarterly, upon completion, or upon reaching milestones? Most firms bill monthly, but some transactional matters or flat-fee arrangements use a different schedule.
• Payment terms — net 15, net 30, due upon receipt? What is the consequence of late payment — interest charges, suspension of work, withdrawal from the case?
• Costs and expenses — what costs will be passed through to the client? Filing fees, service of process fees, deposition transcripts, expert witness fees, travel expenses, copying and postage, electronic research charges, court reporter fees. List the categories. Specify whether costs are advanced from the trust account or billed separately. In contingency cases, specify whether costs are deducted from the recovery before or after the contingency percentage is calculated.
• Third-party vendors — will the client be billed directly by expert witnesses, court reporters, or other vendors? Or will the firm advance those costs and seek reimbursement?

Conflict check information

You cannot draft a retainer agreement until you have cleared conflicts, and you cannot clear conflicts without the right information. Your intake should capture everything the conflicts database needs:

• Opposing parties — full legal names of all adverse parties (individuals and entities). Include known aliases, DBAs, and affiliated companies.
• Related parties — co-defendants, co-plaintiffs, insurers, guarantors, lenders, landlords, business partners, and any other parties with a material interest in the outcome.
• Witnesses and key individuals — names of known witnesses, experts, mediators, or arbitrators who may be involved. A conflict with a key witness can be just as disqualifying as a conflict with a party.
• Prior counsel — has the client been represented by another attorney in this matter? If so, why did that relationship end? This is relevant both for conflict-checking and for identifying potential issues with the file transfer.
• Referral source — who referred the client? This matters for business development tracking, but it also matters for conflicts. If the referral source is a party to the dispute or has interests adverse to the client, you need to know that before you sign the retainer.

Communication preferences and expectations

More client dissatisfaction comes from communication failures than from bad legal outcomes. A client who loses a motion but was kept informed along the way is far less likely to file a grievance than a client who wins the case but never heard from their lawyer for three months. Your intake should establish communication expectations from the start:

• Preferred contact method — phone, email, text, secure portal, regular mail? Some clients want weekly email updates. Others want a phone call only when something significant happens. Document the preference.
• Frequency of updates — how often does the client expect to hear from you? Weekly, biweekly, monthly, or only when there is a development? Setting this expectation at intake prevents the "I haven't heard from my lawyer in two months" complaint.
• Emergency contact — is there someone other than the client who should be contacted in an emergency? Particularly relevant in criminal defense, immigration (where detention is possible), and family law (where safety concerns exist).
• Confidentiality concerns — is there a reason the client does not want mail sent to their home address or calls made to their work number? In family law and employment matters, this comes up frequently. Capture it at intake so the first letter you send does not end up in the wrong hands.

File retention and document handling

Most attorneys do not think about file retention until the matter is over and the client wants their file back. By then, you are reconstructing the policy from memory and hoping your retainer said something about it. Your intake should address file handling up front:

• File retention period — how long will you retain the client's file after the matter concludes? Most jurisdictions require a minimum period (often five to seven years), but your firm may have a different policy. State the period.
• File return vs. destruction — at the end of the retention period, will the file be returned to the client or destroyed? If destroyed, by what method (shredding, secure digital deletion)?
• Original documents — will the firm retain original documents during the engagement? What is the process for returning originals at the conclusion of the matter?
• Electronic records — in the age of cloud storage and digital case management, where are the client's documents stored? What happens to electronic copies at the end of the retention period?

Termination provisions: how the relationship ends

No attorney likes to think about termination at the beginning of an engagement, but this is exactly when you need to think about it. A retainer that does not address termination leaves both sides exposed when things go sideways — and things go sideways more often than anyone in the profession likes to admit.

• Client's right to terminate — the client can fire you at any time, in any jurisdiction. That is not negotiable. What is negotiable is the financial consequence: does the client owe fees for work already performed? Is there a kill fee? Are costs advanced from trust recoverable?
• Attorney's right to withdraw — under what circumstances can you withdraw from the representation? Non-payment of fees, failure to cooperate, fundamental disagreement about case strategy, the client engaging in fraud? Your intake should capture the firm's standard withdrawal triggers so the retainer includes them.
• Court approval — in litigation matters, withdrawal requires leave of court. Your intake should note whether this matter is or will be in litigation, because the termination provisions need to account for the possibility that the court denies a motion to withdraw.
• Transition obligations — upon termination, what happens to the file? Who is responsible for finding successor counsel? Will you cooperate with the transition? Is there a fee for file preparation and transfer? Address this at intake and document it in the retainer so there is no ambiguity when the relationship ends.

Why the retainer intake is universal

Unlike a commercial litigation intake or a family law intake, which are designed for specific case types, the retainer agreement intake applies to every matter in every practice area. A personal injury case needs the same fee-structure clarity as a corporate transaction. A criminal defense retainer raises the same trust account issues as an estate plan. An immigration matter requires the same conflict check protocol as a partnership dispute.

The retainer is the one document that defines the attorney-client relationship itself — not the substance of the case, but the terms under which you will handle it. And the intake form that feeds the retainer is the one document that every law firm needs regardless of size, practice area, or client base.

What separates a retainer that protects you from a retainer that exposes you is the quality of information you collect before drafting it. A retainer agreement intake form that walks through each of these categories — client identity, scope, fee structure, trust account terms, billing, conflicts, communication, file retention, and termination — ensures that nothing falls through the cracks. The alternative is drafting from assumptions, and assumptions are what fee disputes are made of.
