Closing letters can serve as the official endpoint of the attorney-client relationship. They tell the client that their matter is resolved or that ongoing representation is no longer necessary, and they recap essential information about final steps, documents, and responsibilities.

To write a closing letter to clients that is clear and empathetic isn’t just a formality. It helps clients feel acknowledged, ensures everyone has the same understanding of what’s been done, and reduces confusion if they return with questions later. Further, it helps to ensure that the attorney-client relationship is seen as positive, which can lead to referrals down the line, which is great for your law firm’s continued success! The letter can also satisfy ethical or regulatory obligations, such as confirming that you’re no longer acting as the client’s attorney and that all client documents have been kept in their place.

As a rule, it’s best not to follow a sample closing letter or closing letter template to the tee. Instead, let’s go through some important considerations so that you can learn how to write a closing letter to clients that covers the right points and maintains a professional tone. Keep reading to learn more!

Clarify the Purpose of the Closing Letter

Your first step is identifying what you want the closing letter to achieve. Is the matter fully settled, with no loose ends left? Did the client decide to switch lawyers or end representation for some reason? Maybe you’re closing the file because all deadlines have passed and no further action is needed. The reason for writing the letter shapes how you approach the content and what tone you use.

Think about the circumstances. If you’re writing because the case concluded successfully, the letter might include a celebratory note and express gratitude. If you’re withdrawing as counsel because of nonpayment or some conflict, the tone might be more direct. Always consider the client’s perspective. Even if you had a challenging relationship, they probably appreciate a polite, factual statement. Effective closing letters help clients feel acknowledged, ensure everyone has the same understanding of what’s been done, and reduce confusion if they return with questions later. A well-structured closing letter clarifies that you respect the client’s time and that you’re committed to wrapping things up on a good note (where possible).

Decide on Timing

The timing of a closing letter often depends on when the case truly ends. If a settlement is reached, you might wait until the settlement funds clear and any final tasks (like distributing checks) are done. If you finalize a contract or legal document, you can send the letter soon after. Leaving a large gap between finishing the work and sending the letter risks confusion about whether you’re still on the case. Also, some ethical rules require you to inform the client promptly if you’re withdrawing representation or if a specific representation period has concluded. Ensure that the client is informed about when they can expect to receive their final bill and the timeframe available for payment.

If you realize you should have sent a closing letter months ago, it’s still better to send one late than never. A delayed letter can still remind the client that no further action is needed on your end and that the matter is closed. If you’re letting them know you no longer represent them for any future issues, it’s even more important to be clear about that status, so they don’t assume you’re still their lawyer for new problems.

Determine Format and Delivery Method

In many situations, a letter on firm letterhead, sent by standard mail, is standard practice. Some lawyers also email a copy for the client’s convenience. Physical letters can feel more official, especially for older or more traditional clients. That said, email might be the best option if the client typically communicates that way. You could do both: send the physical letter to maintain formality and email a scanned version so the client can read it right away.

Ensure that the letter does not include any personal financial information to maintain confidentiality and adhere to professional standards.

Keep the format professional. A typical setup includes your firm’s address, date, client’s name and address, a subject line referencing the matter, and the main body. End with a polite sign-off, and consider referencing any enclosures (like final invoices or important documents). If your bar rules require specific disclaimers, consider adding them. Even if no disclaimers are required, you might add a line stating that this letter serves as confirmation that no further representation is provided unless you and the client sign a new agreement.

Start With a Polite Greeting

A friendly but respectful greeting helps set the tone. You might say “Dear [Client Name],” as you would in a standard business letter. There’s no need for elaborate introductions, but a brief acknowledgment, such as “I hope this finds you doing well,” can maintain a cordial feel.

If you had a challenging relationship or parted ways under tense conditions, keeping the greeting neutral is still appropriate. Avoid letting any frustration seep into the opening lines. The goal is to remain courteous and professional, reinforcing that you manage your client relationships with care—even in circumstances where the attorney-client bond is ending. Concluding the letter on a positive note can enhance client satisfaction and foster future referrals.

Reference the Completed Matter or Relationship

Early in the letter, identify the specific legal matter or case number you handled. If you worked on multiple issues, clarify which matter you’re closing out. This helps the client quickly understand what the letter pertains to, especially if they have other ongoing business with your firm. For instance, if you represented them in a personal injury claim that recently settled, you might write:

“In reference to your car accident claim arising from the incident on [Date], I am writing to confirm that all matters related to this claim are now concluded.”

If you’re withdrawing from representation or the client decided to end the relationship, state that fact plainly. Let them know any effective date of the withdrawal or that the formal representation period concludes on the date specified in the letter.

Summarize Work Done and Results

A short recap of the work your law firm performed helps the client see what was accomplished and ensures there’s no confusion about tasks left undone. You don’t have to list every detail or replicate your invoices. Instead, offer a concise overview, such as:

• “We investigated the accident, filed suit against the responsible driver, and successfully negotiated a settlement.”
• “We drafted and finalized the contract you needed for your new business venture, including revisions to meet compliance standards.”

Even if the matter didn’t end with the result the client hoped for (like losing a case in court), mention that the final steps were taken to close out the proceeding. The aim is to confirm your role is complete.

Note Any Outstanding Tasks or Returning Original Client Documents

Sometimes clients have a final invoice to pay, or maybe you need them to sign a release form to finalize a settlement. If the representation is finishing and a minor follow-up item lingers, highlight it:

• “Enclosed please find a release you must sign for the insurance company to issue your settlement check.”
• “We have one final invoice attached; payment is due within 30 days.”

Consider including a feedback request to gather client insights and improve future service offerings.

If all bills are paid, state that the account is fully settled and that no further payment is required. This reassurance can help them relax and avoid future confusion. If your local rules require you to return original documents (like wills or property deeds) or store them for a certain period, mention that process. Maybe you keep documents in storage for five years, or you’re returning the entire file to the client’s home address. By addressing these logistics in the letter, you minimize back-and-forth communications later.

Mention the Issue of Future Representation

If you’re definitely done and won’t be automatically representing them on any new matters, clarify that the specific attorney-client relationship has concluded. Clients sometimes assume their lawyer is still “on call,” especially if they get more letters or calls about a related problem. Words like “Our representation on this matter is now concluded, and no additional services will be provided without a separate agreement” can prevent confusion. If the relationship ended on good terms and you’re open to working with them again, you can say:

“If you need legal help in the future or have additional questions, we’d be happy to discuss representing you under a new engagement. Please contact our office at any time if something comes up.”

In cases where you’re withdrawing (perhaps they haven’t paid or you have a conflict of interest), your wording might be more final. Let them know they should hire new counsel if they want further assistance or if any deadlines remain. If there’s a statute of limitations or upcoming court date, mention that so they understand the urgency.

Address Partial Fault or Liability Issues (for Personal Injury Matters)

If this closing letter concerns a personal injury case that ended, it might be relevant to mention any partial fault or liability determinations that arose. Often, clients only vaguely recall how comparative negligence or partial fault might affect future claims. If they received a settlement or verdict that accounted for some percentage of fault, you could remind them:

“Please remember that the settlement reflects the finding that you were 10% responsible for the accident, in line with this state’s comparative fault rules. That percentage impacted the final settlement figure we reached with the insurance company.”

Though not always necessary, acknowledging the fault allocation can help them see why the final result might have been lower than they expected or why certain negotiations played out as they did. It closes the loop on how partial fault impacted their case outcome.

Handling Clients Who Are Dissatisfied and Requesting Client Feedback

Sometimes the client is disappointed with the outcome of your representation letter. The closing letter remains important in these cases—maybe even more so. You can acknowledge that you appreciate their patience or involvement, and confirm the steps you took to close out the matter. If you’re returning unused retainer funds or original documents, mention that plainly. You don’t have to defend the entire case in this letter, but you do want to document that your representation is finished and that they can find new counsel if needed.

In cases where you suspect the client might file a complaint or malpractice claim, consult your jurisdiction’s rules. You usually still send a closing letter, but you might avoid certain admissions or statements that create legal risk. Focus on factual, neutral phrasing. If you must withdraw because of a conflict or problem, mention that the situation prevents you from further representation, referencing any relevant rule or your retainer agreement.

Consider Cultural or Language Needs

If your client primarily speaks Spanish or another language, a closing letter in their preferred language can show courtesy and help them fully grasp the content. Some attorneys provide an English version along with the translated letter. This can reduce the chance of misunderstandings and let you demonstrate that you’re respecting their cultural context. Remember that nuance matters—use a native translator or a staff member fluent in the language rather than relying solely on machine translation.

Confirm That No Further Action Is Required

Clients sometimes think the lawyer might do something else behind the scenes, but representation letters should clearly state that no further actions are pending. If your tasks are done, say so directly:

“No further actions by this firm are pending, and we consider the representation for your car accident claim closed. Should any additional issues arise in the future, you can reach out to us or another attorney, as our active engagement on this matter has ended.”

When you remove any ambiguity about the next steps, you reduce random calls six months down the line asking if you followed up on something. If you do have a small leftover action, highlight it as urgent or optional so the client knows the timeline.

Provide Contact Info for Any Future Needs

If you remain open to representing them in a different matter or if they might have an unrelated legal question later, give them your updated contact details. State that a new agreement or retainer would be needed for fresh matters. This courtesy helps maintain a relationship in good standing, possibly leading to referrals or future business. Consider including a feedback questionnaire to gather client insights and improve future service offerings. If, on the other hand, the relationship ended badly or you do not wish to represent them again, it’s still polite to write a closing letter to clients that includes basic office contact info or a note telling them to seek independent legal counsel if something new arises. Professional courtesy can preserve your reputation even in difficult endings.

Archiving and File Retention

Your bar or jurisdiction usually has guidelines on how long you must retain client files after closing a case. When you write a closing letter to clients, you can mention that you’ll keep a digital or physical copy of relevant files for a certain number of years, after which they might be destroyed unless the client requests otherwise. If you need to store certain records for future reference, let the client know. This approach clarifies that the client can still request documents down the road, within reason, and before any scheduled destruction date. Good archiving practices let you respond quickly to new inquiries or legal questions without rummaging through disorganized storage.

Finalizing and Sending the Letter

Once you’ve drafted your text, read it over to ensure it’s coherent, free of overly technical jargon, and that it states the main points concisely: the matter is closed, the reason why, any final steps or documents, and a note about future representation. Double-check any references to rules or disclaimers. If the tone feels too stiff or too casual, adjust it to match your usual firm style and the nature of your relationship with this particular client. Then print on firm letterhead or prepare a well-formatted PDF if you’re sending it electronically. Keep a copy in the client’s file or within your practice management system. Confirm they received it and that there’s no misunderstanding about the end of your legal services.
