A legal billing description explains the work performed for a client matter. It should be clear enough for billing review and client understanding, while avoiding unnecessary detail that could create confidentiality concerns.
This guide gives law firms a reusable structure for writing stronger billing descriptions.
Legal Billing Description Formula
Use this basic formula:
[Action verb] + [work product or task] + [subject matter] + [purpose or next step]
For example:
Reviewed revised purchase agreement regarding indemnity and termination provisions for partner comments.
The description does not need to tell the whole story. It should give enough context to show what work was done and why it belonged to the matter.

Copyable Billing Description Template
Use the following template when drafting or reviewing legal time entries.
Component | Prompt | Example |
Action | What did you do? | Reviewed, drafted, analyzed, revised, prepared, researched |
Work product | What item did you work on? | Agreement, memo, pleading, email, discovery response |
Subject | What issue or topic was involved? | Indemnity, damages, privilege, venue, settlement terms |
Purpose | Why did the work matter? | For client call, filing, negotiation, partner review, strategy discussion |
Duration | How much time was spent? | 0.3, 0.6, 1.2 |
Code | Is a task/activity code required? | L120, A103, client-specific code |
A practical sentence structure:
[Action] [work product/task] regarding [issue/topic] for [matter purpose].
Examples
Weak Description | Stronger Description |
Worked on agreement. | Reviewed draft services agreement regarding limitation of liability and renewal provisions. |
Email. | Prepared client email summarizing discovery deadline and requested document production. |
Research. | Researched enforceability of non-compete clause under applicable state law. |
Call with client. | Conference with client regarding settlement options and next procedural steps. |
Draft memo. | Drafted memorandum analyzing jurisdictional issues for motion strategy. |
Attention to file. | Reviewed matter correspondence and updated case strategy notes for upcoming status conference. |
The stronger descriptions are still short. The improvement comes from naming the action, subject, and purpose.

Description Starters
Use these action verbs to avoid vague wording:
Reviewed
Drafted
Revised
Prepared
Analyzed
Researched
Conferenced
Summarized
Organized
Compared
Updated
Evaluated
Avoid generic phrases such as:
Worked on matter
Attention to file
Handled documents
Review emails
Miscellaneous work
Followed up
A vague phrase may be fast to type, but it often creates more work during billing review.
Confidentiality-Aware Billing Descriptions
Legal billing descriptions should be useful without revealing more than necessary. Many firms avoid including sensitive legal advice, unnecessary client secrets, settlement strategy, privileged communications, or overly specific factual allegations in invoice descriptions.
A safer pattern is to describe the category and purpose of the work, not every confidential detail.
Risky Direction | Better Direction |
Includes detailed privileged advice | Names the type of legal issue at a high level |
Describes confidential settlement strategy | States that settlement issues or negotiation materials were reviewed |
Includes sensitive personal facts | Uses neutral matter-related language |
Copies internal strategy notes into invoice text | Keeps internal notes separate from billable descriptions |
This guide is for educational purposes only. Billing description standards vary by jurisdiction, client guideline, court requirement, and firm policy.
Billing Codes and Descriptions
Some legal invoices require billing codes, such as UTBMS task, activity, or expense codes. In those matters, a good description still matters.
The code tells the billing category. The description explains the actual work.
Code Role | Description Role |
Classifies the type of work | Explains what was done |
Supports eBilling rules | Supports client understanding |
Helps reporting and review | Reduces vague invoice narratives |
Often standardized | Usually matter-specific |
Review Checklist
Before submitting a legal billing description, check:
Is the correct client and matter selected?
Does the description identify the work performed?
Is the subject clear enough?
Is the duration reasonable for the task?
Is the required billing code included?
Is confidential detail limited to what is necessary?
Would the client understand why this work was performed?
