Verbs to underline
Draft, prepare, and review describe work done inside the office. Record, transfer, retitle, and submit describe work in the outside world, and their absence is informative.
Your quote says flat fee. Here is what still gets billed separately
The Residuary Clause
Hourly conversion triggers
Most engagement letters reserve the right to bill hourly once the file leaves the assumed profile. Out-of-state real property, a closely held business, or a third round of edits are common triggers.
Three funding arrangements
The firm may prepare only a deed and hand you instructions, handle custodian contact for an added fee, or exclude funding entirely. All three exist and only one is stated in your letter.
A line-by-line read of the estate planning engagement letter: what the package price covers, where hourly work begins, and who is actually responsible for funding the trust.
The engagement letter is the only document in an estate plan that describes the transaction rather than the estate, and it is usually the one signed fastest. It arrives after a consultation that went well, it quotes a number that sounded fair in the room, and it gets returned the same afternoon. The number is real. What it covers is narrower than most people assume, and the gap between the quoted package and a plan that actually controls assets is where the second invoice lives. Read the scope paragraph twice before the retainer clears.
The scope paragraph names documents, not outcomes
Most flat-fee scopes are written as a list of instruments: a revocable trust, a pour-over will, a durable financial power of attorney, a health care directive, a HIPAA authorization, and sometimes a certification of trust. That list is a drafting deliverable. It is not a statement that your house will be in the trust, that your brokerage account will retitle, or that your bank will accept the power of attorney on the first try. A careful reader looks for verbs. Draft, prepare, and review describe office work. Record, transfer, retitle, and submit describe work on the outside world, and those verbs are frequently absent.
Flat fee, hourly, and the sentence that converts one into the other
A flat fee prices a predictable file: two clients, one marriage, adult children, no business interest, no prior trust to unwind. The engagement letter almost always contains a clause reserving the right to bill hourly for matters outside that assumption, and the trigger conditions are worth underlining. Common triggers include a second round of substantive changes after the draft review, a beneficiary with special needs, real property in another state, a closely held company requiring an assignment of membership interest, and any estate tax planning that touches the federal return the IRS is responsible for administering. Hourly is not a penalty. It is the honest price of an unpredictable file, and knowing the trigger in advance lets you decide whether to bring the complication forward or leave it out.
Funding is the expensive half, and it has an owner
A revocable trust does nothing until assets are retitled into it, and the engagement letter should say plainly who performs that work. Three arrangements are common. The firm prepares a new deed for the residence and hands you written instructions for everything else. The firm prepares the deed and also contacts custodians, banks, and transfer agents on your behalf, usually at an additional flat fee or hourly. Or funding is excluded entirely, with a sentence to that effect buried near the end. Ask which one you are buying. An unfunded trust is a drafted plan, not a finished one, and the distinction shows up only in probate court years later.
Costs that are never part of anyone's fee
Third-party charges pass through regardless of how the legal work is priced. County recording fees for a deed vary by jurisdiction and page count, some states add a document transfer tax or require a preliminary change of ownership report, and a few counties still want an original wet-ink signature delivered by mail. Notary fees, courier charges, and the cost of a certified copy are small individually and add up across a full funding cycle. If the property carries a mortgage, check whether the loan documents contain a due-on-sale clause and confirm the transfer to your own revocable trust falls within the standard federal exception. Title insurance treatment is worth one direct question to the attorney before the deed is signed.
What finished actually looks like
Drafted means the documents exist. Finished means they were executed correctly under your state's rules for witnesses and notarization, the deed was recorded and the stamped copy returned, account custodians confirmed the retitling in writing, beneficiary designations on retirement accounts and life insurance were updated to match the plan, and the successor trustee and agent know where the originals are kept. A closing letter from the firm typically marks the end of the engagement, which means later questions bill as new matters. Ask for a funding checklist you can work through and return, marked with what remains open.
The most useful thing a careful reader can do is convert the engagement letter into a short list of open items before signing it: who records the deed, who calls the custodians, what triggers hourly billing, and what event closes the file. Those four answers turn a quoted price into a schedule of work.
