Before a law firm begins working for you, it will almost always ask you to sign an engagement letter. Many clients treat this document as boilerplate — a formality to be acknowledged and filed away without careful review. This is a mistake. The engagement letter is a contract between you and your law firm, and it governs the most fundamental aspects of the relationship: what the firm will and will not do for you, what you will pay and how, who owns the relationship, what happens if you disagree, and how the engagement can be ended.
Taking fifteen minutes to read and understand an engagement letter before you sign it is one of the most practical and cost-effective things a new business client can do. The following is a guide to what engagement letters typically contain, what to look for, what red flags to watch for, and what is reasonable to push back on.
What an Engagement Letter Is and Why Firms Use Them
An engagement letter serves several functions simultaneously. From the law firm’s perspective, it defines the scope of the representation so that the firm cannot later be held responsible for legal matters it was not asked to handle. It establishes the fee arrangement and payment terms. It discloses potential conflicts of interest and, where applicable, obtains the client’s informed consent to proceed. And it satisfies the ethical requirements imposed on attorneys by state bar rules, which in most jurisdictions require attorneys to communicate the basis of their fees to clients, preferably in writing.
From the client’s perspective, the engagement letter is an opportunity to confirm your understanding of what the firm has been hired to do, what you will pay, and what protections you have if the relationship does not go as expected. It is also your best opportunity — before work has begun and the relationship has any inertia — to negotiate terms you find objectionable.
Scope of Work: What the Firm Is and Is Not Being Hired to Do
The scope of work provision is the most important section of the engagement letter, and it is frequently the most ambiguous. The scope defines the specific matter or matters for which the firm is being retained, and it determines the outer limits of the firm’s representation. Work that falls outside the defined scope is generally not the firm’s responsibility unless separately agreed.
Read the scope provision carefully and compare it to your understanding of what you asked the firm to do. If you hired the firm to help you form a new entity and review your founder agreements, the scope should reflect that. If it says only “general corporate matters” without further specification, the scope may be either too broad (creating uncertainty about billing) or too narrow (excluding specific things you need done).
Pay particular attention to what the engagement letter says the firm is not doing. Many engagement letters include explicit exclusions — statements that the representation does not include tax advice, regulatory compliance in specific jurisdictions, litigation, intellectual property registration, or other specific matters. These exclusions are not sinister, but you need to know about them so you understand that you will need to engage separate counsel for those areas or ask this firm to expand the scope.
If the scope is ambiguous, ask for clarification in writing before you sign. A follow-up email confirming your shared understanding of what the engagement covers is a reasonable step that can prevent significant misunderstandings later.
Billing Rates, Fee Structures, and Payment Terms
The engagement letter should specify clearly how the firm intends to bill for its services. This includes the hourly rates for each attorney and paraprofessional who may work on your matters, or — in the case of a flat fee arrangement — the agreed-upon price and what it covers. If the firm uses blended rates, the letter should describe how those rates are calculated.
Pay attention to whether the letter specifies that rates are subject to change, and if so, how often and with how much notice. Annual rate increases are common at law firms. The engagement letter may reserve the right to increase rates, sometimes with only 30 days’ notice. If you are entering an ongoing relationship rather than a one-time engagement, you may want to negotiate a rate lock for a defined period or require more advance notice of rate increases.
The billing provisions should also specify how frequently invoices are sent (monthly is standard), when payment is due (typically net 30), and what happens if you do not pay on time. Some engagement letters include provisions for interest on overdue balances or the right to stop work for non-payment. These provisions are generally enforceable, so understand them before you sign.
If the firm requires a retainer deposit, the engagement letter should describe the amount, how it will be held, how it will be drawn against as work is performed, and what happens to any unused balance at the conclusion of the engagement. Confirm that the retainer is held in a client trust account, as ethical rules require.
Who Does the Work
The engagement letter may or may not address who specifically will handle your matters. If it does not, you should ask before you sign. The letter may identify a lead attorney or relationship partner but be silent about who will actually perform the work. As discussed in the context of choosing a law firm, the quality of the actual attorney handling your day-to-day work is enormously important, and this is the time to confirm those expectations.
Ask whether the engagement letter can be amended to identify the primary working attorney and to require the firm to notify you before reassigning your work to a different attorney without your consent. Firms are not always willing to agree to this, but it is a reasonable request, and a firm that takes client service seriously will generally be willing to at least discuss it.
Conflict of Interest Disclosures and Conflict Waivers
Law firms are required to check for conflicts of interest before agreeing to represent a new client. If the firm has identified a potential conflict — for example, because it represents another company in your industry, a person who has had dealings with you, or a company that might in some future transaction be adverse to you — the engagement letter will typically include a conflict disclosure and ask you to waive the conflict.
A conflict waiver is a significant document that requires careful attention. Before signing a conflict waiver, you should understand exactly what conflict is being disclosed, why the firm believes it is a conflict or potential conflict, and what the implications are for your representation. Specifically: will the attorneys representing you have access to confidential information about the other client, and vice versa? Has the firm erected information barriers (sometimes called ethical screens or Chinese walls) to prevent cross-contamination of confidential information?
You are not required to sign a conflict waiver. If a conflict makes you uncomfortable or seems like it could genuinely compromise the quality of advice you receive, you should either decline to sign and seek different counsel, or negotiate additional protections before you agree. The fact that a firm asks you to sign a conflict waiver does not necessarily mean the conflict is disqualifying — many conflict situations are genuinely manageable with appropriate safeguards — but it does mean you should evaluate the situation carefully rather than treating the waiver as a formality.
Confidentiality and Document Retention
Most engagement letters include a provision noting that the firm’s confidentiality obligations to you are governed by the applicable state bar’s rules of professional conduct. This is standard and appropriate. Some letters go further and describe the firm’s specific policies on document retention — how long the firm will keep your files after the engagement concludes and what it will do with them after the retention period expires.
If the letter includes a document retention provision, note how long files will be kept and whether you will receive notice before they are destroyed. For matters involving ongoing contractual relationships, intellectual property, or other matters with long-term relevance, you want to ensure that you have your own copies of all important documents. Do not rely solely on your law firm to be the repository of record for your legal files.
Dispute Resolution Provisions
Many engagement letters include provisions specifying how disputes between you and the firm will be resolved if they arise. The most common arrangements are: internal review procedures (you escalate complaints to a senior partner or managing partner before pursuing other remedies), binding arbitration (disputes are resolved by a private arbitrator rather than in court), or fee dispute resolution through the relevant state bar association.
Arbitration provisions in engagement letters deserve careful consideration. Arbitration can be faster and less expensive than litigation for resolving fee disputes, but it typically limits your right to pursue claims in court, may restrict discovery, and may require you to arbitrate in a location or before an arbitration provider that is more convenient for the firm than for you. If an engagement letter includes a mandatory arbitration provision, ask about the rules that will govern the arbitration and who pays the arbitration costs.
Some states limit the enforceability of certain provisions in attorney engagement letters as a matter of public policy, so the specific protections available to you will vary depending on your jurisdiction.
Termination Provisions
The engagement letter should describe how the relationship can be ended — by either party. You generally have the right to terminate your relationship with your attorney at any time, for any reason or no reason, subject to paying for work already completed. The attorney’s right to withdraw from the representation is more constrained: attorneys can generally withdraw only for good cause and in a manner that does not prejudice the client’s interests, subject to court approval in pending litigation matters.
The engagement letter may specify that upon termination, any unpaid balance becomes immediately due, and that the firm may retain your files until the balance is paid (known as a retaining lien). This is a legitimate provision, but it is worth knowing about in advance so you understand the practical constraints on terminating the relationship if a billing dispute arises.
What to Push Back On
Not every provision in an engagement letter is negotiable, but some are. Billing rates are often more negotiable than they appear, particularly if you are committing to an ongoing relationship or anticipate significant volume. Annual rate increases can sometimes be capped or delayed by negotiation. The scope of work can almost always be made more specific if you ask.
Mandatory arbitration clauses can sometimes be removed or modified if you express concern about them, particularly if you are bringing meaningful business to the firm. Conflict waivers can sometimes be limited to specific matters rather than granted broadly for any future conflict involving related parties.
The key is to engage with the document before you sign it rather than after. A law firm that takes offense at a client asking thoughtful questions about their engagement letter is sending you information about the kind of relationship it expects. A firm that welcomes the dialogue and addresses your concerns directly is demonstrating the kind of professional relationship worth entering.
