The short answer
At most midsize and large law firms, the COO or executive director and the CIO or IT director typically run a technology evaluation, knowledge and innovation leaders champion it, and a partner committee approves larger commitments. At small firms the owning lawyer decides. Clean finds law firms and legal teams with a real reason to buy what you sell and names who decides.
At most midsize and large law firms, the COO or executive director and the CIO or IT director typically run the evaluation, knowledge and innovation leaders champion the tool, and the managing partner or a partner committee approves larger commitments. At solo and small firms there is no committee: the lawyer who owns the firm decides.
That is the typical shape, not a rule. No source we found sets a standard approval path or a dollar line above which partners must sign. The clearest description we found is an example from the executive director of the Association of Legal Administrators (ALA), in an article dated June 18, 2026: partners should be consulted on a change in billing software, while an administrator runs procurement, testing and implementation.
The table maps each role; the sections below define them. For the end-to-end process, read how to sell software to law firms; the legal tech hub maps the rest of the section.
Who does what in a law firm technology decision. Role definitions marked ALA come from its 2018 benchmark job descriptions; everything else is typical, not measured, and varies by firm.
| Role | What it owns | What it needs to see from a seller | How it usually enters the deal |
|---|---|---|---|
| Managing partner and partner committee | Firm strategy, larger commitments and the firm's AI rules | Cost, client confidentiality risk, partner adoption, client expectations | At approval; earlier for firm-wide or AI tools |
| COO or executive director | The business side; reports to the managing partner or a committee (ALA) | Rollout plan, total cost with training, a case for the committee | Sponsors or runs the evaluation |
| CIO or IT director | Technology systems; reviews new products and systems (ALA) | Security, single sign-on, data retention, integrations | Security and technical review |
| Chief knowledge or innovation officer | AI, knowledge and how work product gets made | Real work product, a measured pilot, AI policy fit | Finds and champions the product |
| Practice group leader and practice area administrator | The group's strategic plan (ALA) | Effort saved on real matters, no added client risk | Champions practice tools, runs group pilots |
| Finance director | Financial, time, billing and collection systems (ALA) | Pricing model, billing effects, budget fit | When billing systems are touched |
| Privacy or security | Keeping confidential information secure (ALA privacy role) | Security documents, breach notice terms | The vendor security review |
Firm size decides which of these people you meet at all. In the ABA's 2024 Legal Technology Survey data, 97% of solo practitioners and 90% of lawyers at small firms (2 to 9 attorneys) said they make their own tech decisions. Firms of 100 or more attorneys look different: 50% employ dedicated IT staff or chief information officers.
The newer roles are growing. ILTA's 2026 Technology Survey (508 responding firms, published September 14, 2026) says "many firms anticipate additional headcount needs across IT, innovation, security, training, knowledge management, and data science." That is a direction, not a count of hires.
Which roles you will typically meet, and who signs, by size. This is our reading of how firms commonly work, not a measured figure:
The law firm COO, often titled executive director or principal administrator, runs the business side of the firm so the lawyers can practice. The ALA's 2018 description says the role "assists in developing organizational and business goals including participation in meetings of the firm's governing body," "generally directs a supervisory staff responsible for carrying out the firm's day-to-day operations," and reports to the managing partner or the management, executive or policy committee. If the person is a lawyer, they are "not primarily involved in the practice of law."
For a seller, the COO usually owns the decision without owning the final signature (typical). Because the role directs day-to-day operations, the COO sees the whole cost of a change: the contract, the rollout, the training hours, and which team carries the work.
What the COO needs to see: a rollout plan with named owners on both sides, total cost including training time, contract terms the firm can accept, and a one-page case the COO can take into the committee meeting. Write it for them; it is the document that travels.
For larger commitments, typically yes, though rarely alone. At midsize and large firms the managing partner usually works with a partner committee, often called the executive or management committee, and the COO reports to that group (ALA). Smaller purchases are often settled by the COO or IT director within an agreed budget (typical). Each firm draws that line itself, so ask what goes to committee.
Firm management also owns the AI rules. ABA Formal Opinion 512 (July 29, 2024) says "managerial lawyers must establish clear policies regarding the law firm's permissible use of GAI." In ILTA's 2026 survey, 57% of responding firms under 50 lawyers had a formal generative AI policy in place, against 98% at 350 to 699 lawyers and 91% at over 700. This is context, not legal advice: read the opinion's own text, and check anything you rely on with your own counsel.
What the committee needs to see: cost, risk to client confidentiality, whether partners will use the tool, and what clients expect. On that point, in the Thomson Reuters Institute's Future of Professionals 2026 legal report (a single global survey, data gathered March to April 2026), 77% of clients called AI-enabled quality improvements from their firms very important or essential.
The CIO or IT director owns the systems your product has to live next to. The ALA's 2018 description calls the IT director "a senior-level position with overall responsibility for planning, managing and directing the technology and communications systems of the organization," one that "directs planning, budgeting, reviews new products and systems." That makes IT the gatekeeper for security review, integration and rollout (typical), even when an innovation leader found you first.
Clients push security work here. In ABA survey data for 2023, 50% of respondents at firms of over 100 lawyers said a client or potential client had asked the firm to complete a security questionnaire. That questionnaire usually lands with IT, and IT passes its own questions on to you (typical); the law firm vendor security review guide covers what to have ready.
What IT needs to see: single sign-on and admin controls, data retention and deletion terms, where data is hosted, how the product connects to the document, email and time and billing systems already in place, and a support model. The law firm technology guide covers what firms run and when they replace it.
Law firm knowledge management and legal innovation leaders usually champion new tools rather than sign for them (typical): AI drafting and research tools, knowledge and precedent systems, and anything that changes how lawyers produce work product. These roles are missing from the ALA's 2018 benchmark job descriptions excerpt, while ILTA's 2026 survey lists innovation and knowledge management among the areas where firms anticipate more headcount.
Spending is moving toward their remit. At the Thomson Reuters Institute's panel firms (184 firms in its January 2026 State of the US Legal Market report), spending on technology grew 9.7% and on knowledge management tools 10.5% in 2025. Those are panel firms, not all US firms.
AI tools usually pass through their hands (typical), and larger firms put more gates in front of AI. In ILTA's 2026 survey, the share of responding firms allowing only vetted or firm-approved AI apps went from 39% under 50 lawyers to 79% at 350 to 699, and required training before use went from 11% under 50 lawyers to 72% at over 700. What they need to see: the tool on the firm's real work product, a pilot with an agreed success measure, a training plan, and answers to the AI policy. Selling AI to law firms covers the ethics questions they bring.
Practice group leaders bring the use case. They are often the strongest champions for practice-specific products (typical). Beside them, the ALA's practice area administrator "coordinates the efforts of a practice group team and oversees the group's strategic plan," which makes that person a natural owner of a group pilot (typical).
Finance owns the billing side. The ALA's 2018 description has the finance director overseeing "all aspects of the firm's financial, time, billing and collection systems," so anything touching time capture or billing goes through that desk. The privacy role, where a firm has one, is charged with "making sure that confidential information is secure from unauthorized users and data breaches."
Staff count too. In the ABA's 2024 survey budgeting data, 39.2% of respondents rated staff feedback "very influential" on technology purchasing decisions, so the people who will use your product belong in the pilot.
A law firm decision has several owners, so one champion is rarely enough (typical). Multithreading here means a direct line to each role in the table: the innovation leader who found you, the IT director who runs the security review, the COO who carries the rollout, and the partner who will speak for it in committee. See also the buying committee.
Three habits help. Ask the person running the evaluation who approves and what that group needs to see. Give each role its own short document. And re-map when the firm changes: a merger, a new office, a new CIO or innovation leader, or a new client demand on AI or security are common reasons firms buy, and each can change who decides. The legal tech buying signals guide goes through each one. Warm introductions shows who in your network can open a door.
Clean finds law firms and legal teams with a real reason to buy what you sell, shows the evidence behind each one and names who decides. Every prospect is backed by real-world records, and Clean keeps the source behind every reason so each one can be checked; anything Clean cannot confirm stays marked unknown. Clean is not a list vendor or a contact database, and does not send messages for you.

A law firm COO, often titled executive director, runs the business side of the firm. The Association of Legal Administrators' 2018 benchmark description says the role helps set organizational and business goals, takes part in meetings of the firm's governing body, directs day-to-day operations staff and reports to the managing partner or a management, executive or policy committee. On technology, the COO typically sponsors the evaluation.
It depends on firm size. In ABA survey data for 2024, 97% of solo practitioners and 90% of small-firm lawyers made their own tech decisions. At most midsize and large firms, the COO or executive director and the CIO or IT director typically run the evaluation, knowledge and innovation leaders champion the tool, and the managing partner or a partner committee approves larger commitments. The exact path varies by firm.
Typically, tools that change how lawyers produce work: AI drafting and research tools and knowledge and precedent systems. Innovation leaders usually champion and test rather than sign. In ILTA's 2026 survey, the share of responding firms allowing only vetted or firm-approved AI apps went from 39% under 50 lawyers to 79% at 350 to 699 lawyers, so expect a vetting step, a pilot and training.
For larger commitments at midsize and large firms, typically yes, usually together with a partner committee often called the executive or management committee. Smaller purchases are often settled by the COO or IT director within an agreed budget (typical). No source gives a standard threshold, so ask the person running the evaluation what goes to the committee.
A law firm CIO or IT director plans, manages and directs the firm's technology and communications systems. The ALA's 2018 benchmark description says the role directs planning and budgeting and reviews new products and systems. For a seller, the CIO usually gates security review and integration. In ABA survey data for 2024, 50% of firms with 100 or more attorneys employed dedicated IT staff or CIOs.
