Most write-downs are not caused by lawyers billing too much. They are caused by lawyers describing real work badly. The hours were worked and the client would have approved them happily, but the line said "attention to file," and someone in a claims office cut it in half.
Try it before you read on
Run the live agent on a fictional sample matter: pick a case, pick a task, and watch it produce a case brief, a deadline timeline, or a drafted response.
This is not just style. Model Rule 1.5 makes reasonableness the test for every fee, and its factors (time and labor required, difficulty, skill, results obtained) can only be applied to a task a reader can identify. An entry that hides the task hides the analysis, which is why judges on fee petitions and insurance-defense bill reviewers flag the same lines.
Legal billing entry examples, weak and rewritten
These are illustrative examples written for this article, not entries from real matters. Read the middle column the way an adjuster reads it: with no knowledge of your file.
| Category | Weak entry | Stronger rewrite | What changed |
|---|---|---|---|
| Legal research | Legal research. 2.4 | Researched Ninth Circuit authority on tolling of the two-year limitations period for latent injury claims, for use in opposition to motion to dismiss. 2.4 | Names the issue, the jurisdiction, and the filing it feeds |
| Drafting | Work on motion. 3.0 | Drafted argument sections II and III of motion for summary judgment on the negligent hiring count, incorporating deposition testimony of site supervisor. 3.0 | Which motion, which sections, which source material |
| Telephone call | Call with opposing counsel. 0.4 | Telephone conference with opposing counsel (J. Alvarez) to negotiate extension of expert disclosure deadline and scope of supplemental production. 0.4 | Names the other lawyer and what was actually negotiated |
| Court appearance | Court. 4.5 | Appeared and argued defendant's motion to compel further responses to Requests for Production 12 to 19 before Judge Hartman; granted in part. 2.1 | Hearing, relief sought, judge, outcome; travel split out |
| Travel | (buried inside the 4.5 above) | Travel to and from Superior Court for hearing on motion to compel (billed at 50 percent per client guidelines). 2.4 | Rated per the guidelines instead of hidden in the appearance |
| Document review | Review documents. 6.0 | Reviewed and coded 412 pages of plaintiff's employment and payroll records (PLTF 001102 to 001514) for responsiveness and privilege ahead of the Rule 30(b)(6) deposition. 3.2 | Volume, Bates range, purpose, and a real unit of work |
| Deposition prep | Prepare for depo. 5.0 | Prepared outline and exhibit set for deposition of plaintiff's treating physician, cross-referencing medical records against the Rule 26 expert disclosure. 2.8 | Names the deponent and the work product created |
| Client communication | Email to client. 0.3 | Drafted status report to client summarizing the court's ruling on the motion to dismiss and recommending mediation before the close of fact discovery. 0.3 | Shows advice given, not just a message sent |
| Incoming mail | Review correspondence. 0.2 | Reviewed plaintiff's supplemental Rule 26 disclosure identifying a second economic expert; calendared 30-day rebuttal deadline. 0.2 | Identifies the document and the consequence it created |
| File management | Attention to file. 1.0 | Reviewed newly produced maintenance logs and updated case chronology and witness list in advance of mediation. 0.6 | Replaces a phrase that means nothing with the real task |
Several rewrites carry lower time values, deliberately. A precise entry is often a smaller entry, because splitting a block forces honest pricing on each piece. The trade is that precise entries survive review and collect near face value.
Block billing, and why reviewers cut it on sight
Block billing stacks several tasks under one time value: "Research tolling issue; draft opposition; call with client; review discovery responses. 6.0." Nothing there is untrue, but no reader can test any part of it. If a reviewer thinks the client call should have been twelve minutes, the only thing available to reduce is the whole block. Many client guidelines ban the practice, and courts on fee petitions routinely apply percentage cuts to block-billed time.
The fix is mechanical. Whenever you are about to write a semicolon or an "and" between two verbs, break the line. That six-hour block becomes four entries, each defensible alone. Ninety extra seconds of typing removes the most common ground for reduction on your invoice.
The phrases that get entries rejected
Some phrases are flags in themselves, whatever the work behind them was. "Attention to file." "Review file." "Work on case." "Miscellaneous." "Prepare for hearing," with no hearing named. Each describes a category rather than an act, and a category cannot be assessed for reasonableness.
Replace the category with the object. "Review file" becomes "reviewed defendant's amended responses to Interrogatories 4 to 9." Keep a short approved verb list (analyzed, argued, calendared, compiled, deposed, drafted, negotiated, prepared, researched, reviewed, revised) and require every entry to open with one and to name something concrete: a document, a person, a deadline, a Bates range. Do not overcorrect. Long narratives read as padding, and privileged strategy does not belong on a page a carrier and possibly a fee-shifting opponent will read.
UTBMS codes and LEDES billing, if you have never seen them
Eventually a carrier or corporate client tells you invoices must arrive in LEDES format with UTBMS codes. UTBMS, the Uniform Task Based Management System, is a set of billing codes developed in the 1990s by a working group involving the American Bar Association, the Association of Corporate Counsel, and PricewaterhouseCoopers, so clients could compare legal spend across firms. Separate code sets exist for litigation, intellectual property, counseling, bankruptcy, and project work.
In the litigation set, task codes run L100 (case assessment and development), L200 (pre-trial pleadings and motions), L300 (discovery), L400 (trial preparation and trial), and L500 (appeal), with subcodes such as L330 for depositions and L450 for hearing attendance. Activity codes beginning with A describe the kind of work: A101 plan and prepare for, A103 draft or revise, A104 review or analyze. E codes cover expenses. One entry therefore carries a task code, an activity code, a time value, and a narrative. LEDES, the Legal Electronic Data Exchange Standard, adopted by a consortium of firms, clients, and vendors in 1998, is simply the file format that delivers all of it to the client's e-billing system.
Two warnings. Coding mismatches get invoices rejected outright rather than reduced, and a rejected invoice can sit for a full cycle before anyone notices. And codes do not rescue a bad narrative: a correctly coded "review documents" still gets cut. Confirm your system exports LEDES natively before accepting the engagement, and weigh that against the numbers in our breakdown of what legal case management software actually costs.
Increments, rounding, and writing it down the same day
Most US firms bill in tenths of an hour, six minutes to the tenth, because the arithmetic is clean. Quarter hours read badly to a sophisticated client: a two-minute call at 0.25 invites a fight you do not need. Rounding up to your minimum increment is accepted practice. Billing time you did not work is not.
Which brings up the honest point about contemporaneous entry. An entry written Friday for Tuesday's work is worse in both directions. It is less accurate, because you no longer recall the twenty minutes spent on the amended scheduling order. And it is less defensible, because a narrative written from memory is generic by necessity: you write "reviewed correspondence" precisely because you cannot remember which correspondence. Reconstruction is where vague entries come from. Write the line when you close the document. When billing a deadline calculation, our court deadline calculator gives you the rule and the date together, which is a useful thing to have in the file anyway.
Getting eight people to write the same way
The gap between firms is rarely talent. It is habit. One associate writing careful entries cannot save an invoice where three other timekeepers wrote "attention to file," because the client reads the invoice, not the timekeeper.
A one-page billing policy does most of the work: approved verbs, banned phrases, one task per entry, a named document or person in every line, travel billed separately, entries in by end of day. Give it to every new hire, and past a handful of people it is worth the hour it takes to put the standard into a short onboarding course everyone actually completes instead of relying on a PDF nobody opens. Then read a sample of entries aloud in a partner meeting once a month. Nothing corrects billing habits faster.
Common questions about legal billing descriptions
What should a legal billing entry include?
Four things: the timekeeper, a past-tense action verb, the specific object of the action (a named document, person, deadline, or hearing), and the purpose the work served. Add the date and a time value in your firm's increment. If a client guideline applies, add the task and activity codes it requires.
What is block billing and why is it bad?
Block billing groups several tasks under one time value, such as "research, draft motion, call client. 6.0." It is bad because no reviewer can judge whether any single task was reasonable, so the whole block becomes the unit of dispute. Client guidelines often ban it and courts commonly discount it.
How detailed should attorney time entries be?
Detailed enough that a reader with no knowledge of the file understands what was bought, usually one to two lines and roughly fifteen to thirty words. Longer entries start to read as padding and risk disclosing strategy to an auditor or a fee-shifting opponent. Specificity matters far more than length.
What are UTBMS codes?
UTBMS is a standardized set of legal billing codes created by an ABA, ACC, and PricewaterhouseCoopers working group so clients can compare legal spend. Each entry gets a task code identifying the phase of work, for example L300 for discovery, and an activity code identifying the kind of work, for example A103, draft or revise.
Why do lawyers bill in six-minute increments?
Because six minutes is one tenth of an hour, so time converts to fees with a single multiplication and totals reconcile cleanly. Tenths are also fine-grained enough to look fair to clients. Quarter-hour increments still exist but draw more disputes, since a short call bills as fifteen minutes.
Can a client refuse to pay for vague billing entries?
In practice, yes. Corporate clients and insurance carriers write reduction rights into their billing guidelines and apply them at invoice review. Beyond contract, Model Rule 1.5 requires fees to be reasonable, and a fee nobody can evaluate is difficult to defend in a fee dispute or a fee petition.
Where a case agent fits into this
Descriptions go vague because the record of the work lives in memory and drains out within a day. Caseagent works inside the case file: it reads incoming filings, drafts, and tracks the deadlines those filings create, so a record of what was done and why already exists at billing time. Any generated entry is still a draft. The responsible attorney reads it, confirms the time value is honest, and owns the narrative before a client sees it.
Caseagent is not a billing or trust accounting system. For that part of the stack, start with our overview of legal billing software for law firms, or the wider category in legal practice management software.
The best billing record is the work itself
Caseagent is an AI agent that lives inside the matter: it reads new filings, researches with citations, drafts documents, and tracks every deadline it finds. That leaves a contemporaneous record of what happened on the file, which is what a good billing narrative is made of. Pre-launch, early access for US firms, attorney review required.
