How Legal Billing Adjustments Are Identified, Documented, and Defended
KEY TAKEAWAYS
Two-stage attorney review — An independent QC review by a second attorney catches inconsistencies and ensures proportionality before anything reaches the law firm
Grounded in policy — Every adjustment traces directly back to the client's Outside Counsel Guidelines
Judgment where judgment is required — Issues like adequacy of description, reasonableness of time, and staffing appropriateness require attorneys with subject-matter expertise
Peer-level firm engagement — When a law firm appeals, the Law Firm Relations Team of former AmLaw and equity partner attorneys engages as equals
Transparency from the start — Firms that receive clear guidelines before review begins are less likely to dispute adjustments after the fact
Compliance improvement over time — The best review processes don't just reduce invoices; they change billing behavior
When a legal invoice undergoes third-party bill review, what happens when adjustments are identified? For corporate legal teams managing significant outside counsel spend, the review itself is generally well understood, but the steps that follow, from documenting legal billing adjustments to communicating them to the law firm and resolving disputes, are less widely known. These downstream steps are often what determine whether adjustments hold or collapse under scrutiny.
To walk through this process, we spoke with LegalBillReview.com's Director of Outside Counsel Spend Analysis, Julia Principe Lane. Julia and her team serve as the final checkpoint before any reviewed invoice is returned to a law firm. Their role is to ensure every adjustment is accurate, clearly documented, and defensible so that if a credit memo is sent to outside counsel, it can withstand the firm's review and any subsequent appeal.
In this Q&A, Julia walks through the resolution process, including how adjustments are communicated, what happens when a law firm pushes back, and why quality control is essential to maintaining trust on both sides of the billing relationship.
What Role Does Quality Control Play in Legal Bill Review?
Q: What is the role of a quality control team in the legal bill review process?
A: Quality control adds a final layer of scrutiny before anything reaches the law firm. After a Legal Analyst completes the initial review of an invoice, our QC team, consisting of a second, independent attorney, steps in to confirm that every adjustment is accurate, consistent, and fully supported. That means checking each adjustment against the client's Outside Counsel Guidelines (OCGs), ensuring the reasoning is clearly explained, and verifying the adjustment is proportional to the identified issue. We also account for any known exceptions or special handling instructions the client has communicated. Essentially, nothing is sent to a law firm without this independent second-stage confirmation.
Q: What does the team verify before a reviewed invoice is sent back to a law firm?
A: We verify three things before a credit memo goes out:
The client's billing guidelines have been applied correctly.
Each adjustment reflects the type and severity of the issue.
The explanation provided to the law firm is clear enough for them to understand exactly why the adjustment was made and where it's grounded in the client's policy.
If anything is incomplete or needs refinement, we make those changes before it's sent. The goal is to deliver a final product that the law firm can review without confusion or ambiguity.
How Are Legal Billing Adjustments Communicated to Law Firms?
Q: What is a credit memo, and how is it used to communicate adjustments to a law firm?
A: A credit memo is the document we send to a law firm that outlines every adjustment made during the review. It includes key information at the line-item level:
What the compliance issue is
How the entry falls outside the client's guidelines
A reference to the specific guideline provision
The adjustment amount.
The firm receives a complete picture of the review findings alongside their original billing. From there, the firm can accept the adjustments by signing the credit memo, which triggers payment, or they can appeal specific findings.
Q: How are legal billing adjustments tied to a client's OCGs?
A: The client's guidelines are the foundation for everything. They define the rules around what's billable, what's not, and how specific issues should be handled. Some guidelines are very prescriptive. For example, certain clients specify that block billing should result in a 20%, 25%, or even 50% reduction. Others take a broader approach, simply stating that block-billed entries won't be paid. The same goes for vague time entries. Some policies allow partial adjustments based on severity, while others require full rejection. Our team applies adjustments that are driven by policy and proportional to the issue, which is what makes them defensible.
How Does Quality Control Ensure Billing Adjustments Are Fair and Defensible?
Q: How does the quality control team ensure that billing adjustments are fair and defensible before they reach the law firm?
A: Quality Control reviews each individual adjustment against the requirements of the client's OCGs and also reviews the billing holistically to ensure that any subjective adjustments are proportionate to the deficiency.
INSIGHT: A client's OCGs may require that time entries for document reviewing must describe the types of documents reviewed and indicate the volume of information reviewed. If a timekeeper enters "Reviewed Documents" for 3 hours, the entry is non-compliant because it neither describes the nature of the documents nor the quantity of information reviewed, so a billing adjustment is required with a judgment call for the amount. Here, we see the timekeeper did work, and will give partial credit for the work performed, so a percentage of the charge will be adjusted to account for the non-compliance with the OCGs.
Q: What are some of the most common types of legal billing adjustments that surface during a review?
A: We see all kinds of adjustments to legal invoices, but some of the most common include:
Administrative or Clerical Work Billed as Legal Time — Tasks that should be treated as overhead, not billed to the client.
Block Billing — Combining more than one task into a single entry without setting forth separately the amount of time it took to complete each task.
Duplicative Work or Effort — Either among multiple timekeepers or within entries submitted by a single timekeeper.
Vague or Inadequately Described Work — Either the specific task performed is not articulated, or the amount of time spent on a task is not properly supported by the billing description as required by the OCGs.
Excessive Internal Conferences — When firm meetings go beyond what's reasonable for the matter.
Overstaffing — Usually, when multiple timekeepers bill for attending an event, where one attendee would have sufficed.
Non-Compensable Travel Costs — Charges that fall outside the client's travel policy.
Client-Specific Guideline Violations — Unique rules that vary from client to client.
Some of these, like block billing, travel costs, and clerical charges, can be identified against clear, binary policy language. Others, such as adequacy of description, reasonableness of time, and staffing appropriateness, require the reviewing attorney to assess context and apply proportional judgment. That distinction is important when evaluating what a bill review process is actually equipped to catch.
INSIGHT: A particular client does not allow law firms to bill for preparing research memos without a specific request from the in-house attorney. When entries for this type of work appear without a reference to prior approval, it requires a judgment call to evaluate the context of the engagement before applying an adjustment.
What Happens When a Law Firm Disputes a Legal Billing Adjustment?
Q: What happens when a law firm disputes a legal billing adjustment?
A: During the onboarding process, law firms are provided with the information and tools needed to appeal adjustments they consider erroneous or unjustified. Once an appeal has been submitted, our Law Firm Relations Team, consisting of former AmLaw and equity partner attorneys who handle firm-facing engagement, works directly with the billing partner at the firm to resolve any disputed entries. When a law firm receives a call from this team, they are speaking with a peer who has practiced at the same level and understands the realities of law firm billing.
INSIGHT: We recently reviewed an airfare expense totaling over $2,500 for a single round-trip ticket. The client's guidelines limit air travel to economy class, so our team verified actual costs for that route and date and determined the charge significantly exceeded the policy limit. The firm appealed, so our Law Firm Relations Team walked them through the analysis, explained the policy basis, and noted that the firm could request a guideline exception from the client in advance if a similar situation arises in the future. The firm understood the basis for the adjustment and accepted the result.
Q: How does the bill review process protect the client's interests and maintain a professional relationship with outside counsel?
A: It starts with the client's Outside Counsel Guidelines. These are the foundation for the entire review, and they're provided to law firms before any review takes place. That's important because it means the rules are transparent from the beginning. Clients invest significant time and effort in drafting guidelines that reflect their priorities around efficiency and cost management, while also recognizing the importance of their law firm relationships. Those guidelines are the basis for every adjustment we make.
Beyond that, we stay in regular communication with both sides. Clients provide ongoing feedback that we incorporate into the review process. And law firms share context, such as previously approved exceptions or case-specific circumstances, that helps prevent unnecessary disputes.
What Should Corporate Legal Teams Know About the Adjustment and Appeals Process?
Q: What should corporate legal teams know about how their invoices are handled during the quality control stage?
A: They should know that Quality Control is dedicated to providing a clear, thoughtful, and fair analysis of law firm billing. While we do adjust bills that contain impermissible or excessive charges, we also strive to help law firms become compliant with the OCGs so their bills don't need adjustment in the future.
INSIGHT: One law firm habitually billed a client for overnight shipping charges, despite the client's OCGs explicitly stating the firm couldn't use overnight or rush shipping without getting permission first. After months of having these charges adjusted by LegalBillReview.com, the firm continued to note the costs on its invoices, but stopped billing for them because the review process changed the firm's behavior without requiring a confrontation.
Every entry on every invoice receives individual attention a second time during the quality control stage. The team takes extra care to apply the client’s rules in a way that reduces waste without unfairly penalizing firms that are doing quality work. The final product gives law firms a clear rationale for each adjustment and enough information to bring their billing into compliance going forward.
Q: What should in-house legal teams know about how LegalBillReview.com handles the adjustment and appeals process?
A: In-house teams should know that LBR employs U.S.-licensed attorneys with practical experience in the relevant areas of law to perform the billing analysis. Every review goes through two stages: an initial analysis by a Legal Analyst, followed by an independent quality control review by a second attorney, who evaluates the adjustments themselves, the severity of each issue, and the language used to describe the findings.
The goal at every stage is to produce work that is clear, neutral, guided by the client's policies, and fair to the law firm. If a firm disagrees with an adjustment, our Law Firm Relations Team carefully reviews the objection, considers any additional context, and works toward a resolution that serves the client's interests without being unfair to the firm.
Q: For companies considering a third-party legal bill review partner for the first time, what should they understand about the adjustment resolution process?
A: The process works best when expectations are set clearly from the start. That means having well-drafted Outside Counsel Guidelines, communicating those guidelines to your firms, and trusting your bill review partner to manage the day-to-day conversations around adjustments.
Most clients come to a bill review partner to solve more than one problem — reducing unnecessary charges, enforcing billing compliance, and lifting the administrative burden of reviewing and negotiating adjustments internally. The more space given to the professionals handling that process, the more effective the results tend to be.
At LegalBillReview.com, our team of U.S.-licensed attorneys and former AmLaw partners works directly with law firm partners to advance the client's interests while maintaining fairness to the firm. That balance is central to everything we do.
