The Cost of Poorly Written Legal Briefs

Something might be eating at your realization rates. Am Law 100 firms averaged 80.93% realization in 2023, their lowest in at least five years, according to survey data reported by The American Lawyer. A firm that bills $200 million at 81% realization collects $162 million and writes off or writes down $38 million.

Client discounts and pricing pressure explain part of the problem. But a surprising share starts with the first draft of a brief.

Poor writing hides in four places

Only one of these costs shows up on a standard billing report, and even that one carries the wrong label.

1. Partner rewrite time. When a partner rebuilds an associate's draft instead of reviewing it, the hours are often absorbed, not billed. The Thomson Reuters Institute puts this silent write-down at about 76 hours and almost $47,000 in lost fees per partner each year.
2. Write-downs with the wrong label. A client who has seen three versions of a brief won't pay for all three. It’s a writing problem, but the write-down gets coded as client sensitivity or pricing pressure.
3. Fixed-fee margin. On a fixed fee, every extra review cycle comes straight out of margin. If a brief was priced for two review cycles and takes four, the firm does half the work for free, and the billing report won’t show that rework was the reason.
4. Client trust. Clients rarely cite writing as the reason they leave a firm. But drafts that need a follow-up call can strain a relationship.

AI makes weak drafts harder to spot

Generative AI can produce polished prose in seconds, giving briefs a solid structure and a confident tone. It’s hard for reviewers to see through the polish to the content that lies below.

A draft can look careful and still hide gaps, citation errors, and arguments that don't advance the case's legal theory. More than 2,000 AI hallucination cases have been documented as of October 2026.

One quick check cuts through the polish. After reading the first page of a brief, a judge should be able to answer three questions: What is the party asking the court to do? Why should the court do it? What does the court need to decide to get there? A brief that can't answer all three usually comes back for another round of revisions, and that cycle generates no revenue.

Code your write-downs for 30 days

You don't need new software to see this cost. One change to how your billing system codes write-downs will show it.

For the next 30 days, whenever a partner writes down time, record the reason: client sensitivity, budget constraints, rework, scope change, or an unusable first draft.

After 30 days, you'll have a directional measure of rework at your firm. After a quarter, you'll see patterns. Over time, you'll have data your management committee can act on.
