Probate Engagement Letter: What to Include and Why

The first call with a family went well. The consultation went better. They want to move forward. What happens next is the probate engagement letter — and for many estate firms it is the least-examined document in the whole practice: a template written years ago, lightly edited for each matter, signed and filed. That is a missed opportunity. A well-built probate engagement letter does more than satisfy the fee-communication rules. It tells the family exactly who you represent, what you will and will not do, how they will be billed, and what the next several months will look like. Done well, it prevents the misunderstandings that turn a routine estate into a fee dispute or a grievance.

This guide walks through what a probate engagement letter should cover, where probate matters differ from ordinary retentions, and how to deliver the letter to a family that is still grieving. It is general practice guidance, not ethics advice: professional-conduct rules, fee rules, and court-approval requirements vary by state, so check your own jurisdiction’s rules and ethics opinions before changing your template.

What a probate engagement letter actually does

An engagement letter is the written record of the attorney-client relationship: who the client is, what the lawyer has agreed to do, and on what terms. ABA Model Rule 1.5(b) asks lawyers to communicate the scope of the representation and the basis of the fee and expenses, preferably in writing, before or within a reasonable time after starting the work. Many states go further and require a written fee agreement in some or all matters. Even where it is optional, putting it in writing is the norm in estate work, and for good reason.

Probate creates more room for confusion than most retentions. The person who signs the letter is acting in a representative capacity. Other family members expect information and often assume the lawyer works for them too. The fee is usually paid from estate assets rather than the client’s own pocket, and it may be reviewed by a court or questioned by beneficiaries. The matter can run for many months and expand in directions nobody expected at the first meeting. The probate engagement letter is where each of those points gets settled before it becomes a problem.

Identify the client: usually the personal representative

The single most important sentence in a probate engagement letter is the one that names the client. In most jurisdictions, the lawyer retained to help administer an estate represents the personal representative — the executor or administrator — in that fiduciary capacity. The lawyer does not represent the beneficiaries individually, and the estate itself is generally not treated as the client. ABA Formal Opinion 94-380 and the ACTEC Commentaries on the Model Rules both discuss this framework. A minority of states approach the question differently, which is another reason to confirm your own jurisdiction’s position and state it plainly in the letter.

Spell out the consequences in language a non-lawyer will understand:

• Who the client is. Name the individual and the capacity (“you, in your capacity as personal representative of the Estate of…”).
• Who the client is not. State that you do not represent the beneficiaries, heirs, or creditors, and that they may wish to consult their own counsel.
• The dual-role problem. When the personal representative is also a beneficiary — the common case of an adult child serving as executor — explain that your representation covers the fiduciary role. Their personal interests as a beneficiary may diverge from their duties to the other beneficiaries, and on those questions they may need separate advice.
• Communication with family. Explain what you can and cannot share with siblings and other relatives, and that information they share with you is not confidential in the way a client’s is.

Families rarely understand this distinction on their own. A sibling who calls the firm expecting to be treated as a client, and is told otherwise for the first time three months in, is a sibling who now distrusts the process. Saying it up front, in writing and kindly, prevents that.

Define the scope of the probate work

Probate matters grow. A straightforward administration turns up a parcel of real estate in another state, a creditor claim that needs to be contested, or a relative who threatens to challenge the will. If the engagement letter does not draw the boundaries of the work, the family will reasonably assume all of it is included.

A clear scope section usually lists what is included — for example, preparing and filing the petition to open the estate, obtaining letters, required notices to heirs and creditors, the inventory, accountings, and the steps needed to close the estate — and then lists, just as clearly, what is not included unless separately agreed. Common exclusions to consider:

• Will contests and other contested litigation
• Ancillary administration for property located in another state
• The decedent’s final individual income tax return, fiduciary income tax returns, and any estate tax return
• Sale of real property, beyond what the administration itself requires
• Representation of the personal representative in a personal capacity, or of any beneficiary
• Trust administration for a related trust

Model Rule 1.2(c) permits limiting the scope of a representation when the limitation is reasonable and the client gives informed consent. The letter is where that consent is documented. Add a sentence explaining how additional work will be handled — a short supplemental letter or written amendment — so expanding the engagement later is routine rather than awkward.

It also helps to set realistic expectations about time. Families often expect probate to take weeks. Depending on the state, the court, creditor-claim periods, and the complexity of the assets, even an uncontested administration commonly runs many months and sometimes longer. We cover the stages families move through in Probate Timelines: When Families Need an Attorney Most.

Fees, costs, and who pays

The fee section is where probate engagement letters most often fall short, because probate fees work differently from fees in most other practice areas.

State the fee basis precisely. Probate firms use several structures: hourly billing, flat fees for defined stages, and — in a handful of states, California among them — statutory compensation schedules or presumptively reasonable fee schedules for ordinary services. Whatever the model, describe it so a family member could estimate a bill: the rates for each timekeeper, what a flat fee covers and what triggers additional charges, or how a statutory fee is calculated and when extraordinary services require separate court approval.

Explain court review where it applies. In many jurisdictions, attorney fees paid from estate assets may be subject to court approval, or open to objection by beneficiaries. If that is true in your state, say so. Families take comfort in knowing there is a check on the fee, and it heads off the suspicion that the lawyer is simply paying themselves from the estate.

Separate fees from costs. Filing fees, publication of the notice to creditors, certified copies, appraisals, and bond premiums are real expenses that families do not anticipate. List the typical categories and how they will be paid.

Address who actually pays. Fees for administering the estate are generally an expense of administration paid from estate assets, but early in the matter the estate may not yet have accessible funds. If a family member advances a retainer, Model Rule 1.8(f) applies to third-party payment: the client must give informed consent, the payer cannot direct the lawyer’s professional judgment, and client confidences remain protected. Say in the letter whether and how the payer will be reimbursed from the estate.

Handle advance deposits correctly. An advance fee deposit is generally held in the firm’s trust account until it is earned, under Model Rule 1.15 and your state’s trust-account rules. Describe how the deposit will be applied and what happens to any unearned balance.

Co-executors, family members, and conflicts

The conflict check comes before the engagement letter, not after. Run it on the decedent, the proposed personal representative, every known beneficiary and heir, and any obvious creditor or claimant before you agree to take the matter. Probate conflicts are easy to miss because the firm may have represented a sibling in an unrelated matter years ago.

When two or more people will serve together as co-personal representatives and you will represent them jointly, the engagement letter should address that joint representation directly. Under Model Rule 1.7, joint representation requires that the lawyer reasonably believe they can represent each client competently and diligently, and where a conflict exists, that each client give informed consent, confirmed in writing. The letter should explain that information shared by one co-fiduciary generally will not be kept confidential from the other, and what will happen if they come to disagree — often that the firm may have to withdraw from representing one or both of them.

Sibling co-executors are common, and so are sibling disagreements. A paragraph written while everyone is still getting along is far easier to rely on than a conversation held after they have stopped speaking to each other.

Delivering the letter to a grieving family

Everything above can be legally correct and still land badly. The family receiving a probate engagement letter may have buried a parent days earlier. A twelve-page document full of defined terms, handed across the desk with a pen, reads as cold — even when the attorney meant nothing of the kind.

A few practices make the same letter feel considerate:

• Lead with a plain-language summary. A one-page cover note in ordinary English — who we represent, what we will do, how billing works, what happens next — ahead of the formal terms. Families read the summary; the terms protect everyone.
• Walk through it together. Review the key sections in the meeting or on a short call rather than sending it cold. Invite questions about the client-identification and fee sections in particular.
• Give them time. Unless a deadline genuinely requires immediate action, let the family take the letter home. Pressure to sign on the spot is exactly what a grieving client remembers.
• Make signing easy. Electronic signature, with a copy returned immediately, removes a printer-and-scanner errand from a family that already has too many.
• Attach a short duties summary. Many firms include a separate letter explaining the personal representative’s fiduciary duties — to inventory assets, keep estate funds separate, act impartially among beneficiaries, and keep records. It is a service to the client and documents that you advised them.

The tone you set on the first call should carry through to this document. We wrote about that first conversation in The First Probate Call: What to Say to a Grieving Family, and about the whole path from first contact to signed retention in From Death Notice to Intake: How Modern Estate Firms Handle New Leads.

Speed matters here too. The gap between “we’d like to hire you” and a signed letter is where families drift — a relative recommends someone else, or the urgency fades and nothing happens for weeks. A ready template and same-day delivery keep the matter moving, as we discuss in Speed to Lead in Probate.

Ending the engagement in writing

An engagement letter has a counterpart that many firms skip: the closing letter, sometimes called a disengagement letter. When the estate closes, a short letter confirming that the representation has ended, summarizing what was done, noting anything the family still needs to handle (a final tax filing, for example), and explaining the firm’s file-retention policy does several jobs at once.

It makes clear that the firm is not monitoring future deadlines on the family’s behalf. It gives the relationship a gracious ending. And it is a natural moment to offer help with the estate planning many families realize they need after going through probate — a conversation worth having only after the estate work is complete and the family is ready.

Do the same at the other end of the funnel. When a family consults with you and decides not to retain the firm, a brief non-engagement letter confirming that you have not been retained, and noting that deadlines may apply to their matter, protects both sides. Keep any such letter accurate and neutral; the rules on solicitation and communications still apply, and they vary by state, as we cover in Probate Marketing Compliance: Attorney Advertising Rules by State.

The conclusion

A probate engagement letter is not paperwork to rush through on the way to the real work. It is where the firm tells the family, in writing, who it represents, what it will do, what it will cost, and how the matter will end. Firms that treat it as a client-service document rather than a liability form tend to have fewer fee questions, fewer confused relatives, and fewer surprises when the scope grows.

The practical steps are simple: run the conflict check first, name the client and the capacity, list what is and is not included, describe the fee and cost model precisely, address joint representation and third-party payment, lead with a plain-language summary, and close the matter with a letter of its own. Review your template against your state’s rules once a year, and the letter will keep doing its job long after the first meeting is forgotten.
