UTBMS codes explained: tasks, activities and costs

UTBMS codes classify legal services and expenses on electronic invoices, including LEDES files. UTBMS means Uniform Task-Based Management System: task codes identify the work's purpose, activity codes describe what happened and expense codes classify costs. Corporate clients and insurers use these categories to analyse legal spend, with requirements set by each client.

UTBMS codes give clients a shared billing vocabulary

UTBMS gives clients a consistent way to compare work across outside firms. Its official history traces the project to the mid-1990s, involving the American Bar Association, the Association of Corporate Counsel and PricewaterhouseCoopers. Codes let receiving systems group entries and test invoices against client requirements.

The LEDES Oversight Committee develops and updates code sets and hosts the central directory at UTBMS.com. The independent coding group merged with the committee in 2007, although other organisations also create standards. Firms should therefore confirm the issuing body and version their client uses. Some clients require phases rather than detailed tasks.

When one entry covers several tasks, billing staff have to decide how to divide its duration. Sixminute records the working day through automatic time capture and writes one entry per task, ready for review.

Task and activity codes describe different parts of an entry

A task code identifies the work category, while an activity code identifies the action performed. The ABA task codes include L120 Analysis/Strategy, L210 Pleadings and L250 Other Written Motions and Submissions.

For example, a fictional 0.8-hour entry could read: “Draft motion to stay proceedings pending arbitration.” It combines L250 with A103 Draft/revise. The task identifies the motion category; the activity identifies drafting. A106 Communicate (with client) would describe a different action.

A summary-judgment motion belongs under L240 Dispositive Motions, so the task code changes even when the drafting activity stays the same.

An associated copying charge belongs on a separate expense line, using E101 Copying. The official LEDES sample distinguishes fee and expense lines. A time entry narrative explains the work within its category. Separating tasks also avoids the coding ambiguity of block billing, where several tasks share one duration.

Different code sets cover different kinds of matter

The appropriate code set depends on the matter and the client's instructions. The official UTBMS directory provides the full UTBMS codes list by type and issuing body.

• Litigation: L-codes for legal billing cover work from case assessment through pre-trial pleadings, motions and discovery to trial and appeal. The litigation code set has phases L100-L500, with more detailed tasks beneath them.
• Advice and transactions: the counseling code set uses C-codes for general advice. The project code set uses P-codes for transactions and other projects; the bankruptcy code set uses B-codes.
• Specialist matters: separate sets cover workers' compensation, patents and trademarks. eDiscovery codes supplement litigation codes, using L600-L690 phases.

For detailed litigation definitions, consult the UTBMS litigation code list. A phase groups work broadly; a task identifies a narrower category. Familiar codes use a letter plus three digits, but the 2023 patent prosecution schema uses numeric codes.

LEDES carries the codes in an electronic invoice

LEDES, the Legal Electronic Data Exchange Standard, specifies invoice file structures. What firms sometimes call “LEDES codes” are the billing categories carried inside those files. UTBMS supplies the vocabulary.

The main types of LEDES include:

• LEDES 1998B: pipe-delimited text with 24 fields, including separate task, activity and expense fields. The committee describes it as the most widely used US legal e-billing standard.
• LEDES 1998BI: the international text format, with additional tax and currency information shown in its sample invoice.
• LEDES XML 2.x: the 2.0, 2.1 and 2.2 families support more complex billing requirements. The older LEDES 2000 is no longer supported.

The LEDES 1998B field guide explains the simpler format in detail. Current XML releases include 2.1.5 and 2.2.2, both revised in April 2026. Confirm the client's accepted LEDES format before configuring an invoice submission.

Clients use the codes to review spending and budgets

Corporate legal departments and insurers request codes to make outside-counsel spending easier to analyse and control. The UTBMS history identifies both groups as drivers of the original project. For insurance defence firms, the insurer's instructions determine the coding expected on a matter.

Requirements vary: some clients require detailed tasks, while others accept phases or omit activity codes. Thomson Reuters says Legal Tracker accepts LEDES invoices and checks billing compliance, with reports for reviewing spending.

A firm should read the client's outside counsel billing guidelines alongside the code definitions. A valid code identifies a category; the client's agreement determines whether the work is payable and which spending limits apply. Grouping fees by phase also helps the client compare spending with its budget.

How Sixminute prepares the work behind each coded entry

Sixminute records the lawyer's whole working day and writes one entry per task, matched to its client and matter, with duration and a client-ready narrative. It covers every computer application, phone calls through its mobile app and meetings through Outlook and Google Calendar.

Sixminute's Computer Event Reconstruction (CER) reconstructs the working day across every computer application, with no integrations to set up. Work in a court portal is covered alongside work in a document, so the lawyer can review both in one timesheet.

Setup takes about 5 minutes. Sixminute takes no screenshots and logs no keystrokes, and filtering happens on the device. Firm data is encrypted with the firm's own key and hosted in the EU.

Entries stay private to the lawyer until released into the firm's existing system. Lawyers using Sixminute spend about 6 minutes a day reviewing and releasing their timesheet. That gives billing staff task-level records and clear narratives from which to select the client's required codes.

Confirm the client's coding instructions before billing

The firm should agree the code set and invoice format before recording work on a new matter. The official UTBMS guidance directs firms to clients for their classification requirements. Record that decision in the matter's billing setup.

1. Obtain the approved task codes, activity codes and LEDES version, including any client variations.
2. Check the UTBMS activity codes: original ABA activity codes run A101-A111; the 2013 revision extends through A128, adding travel and eDiscovery activities.
3. Confirm whether the client's expense-code list uses E101-E124 or the revised X-codes.
4. Record each task daily and check its narrative against the chosen code. Use the firm's time-entry writing guidance to make descriptions specific enough for billing staff and the client to understand the work.
