Best Legal Research for Solo Practitioners: Nine Tools Priced From 25 to 499 a Month

The best legal research for a solo practitioner is usually two tools, not one: a citator for the filings that need it, and a cheaper search tool for finding cases. For a litigator in one federal circuit that means Westlaw Advantage at a published 256.75 dollars a month. For everyone else, a focused search tool at 25 to 100 dollars a month plus whatever your bar dues already include will cover most of the work. The right answer depends on how often you file, not on which brand is best.

This page is for a US solo attorney who is about to spend money on research and wants to know which seat to buy. We read every published price below from the vendor's own page in September 2026, and we mark anything we could not read ourselves as reported. Informational research, not legal advice.

Best legal research for solo practitioners at a glance

The per year column is our arithmetic on the published monthly and annual figures. For Westlaw it spans a three year term at 18 percent off down to a one year term at list, and we lay out every term on our Westlaw solo practitioner pricing page.

How much should a solo practitioner spend on legal research?

Most solos can do serious research for 300 to 1,200 dollars a year, and the ones who genuinely need Westlaw should expect about 2,500 to 4,800 on top. The test is filings, not practice area: if you file briefs or dispositive motions every week, a citator is worth paying for. If you file a few times a quarter, it mostly is not.

Put a number on it before you buy. Count the filings from the last three months that needed a citation check, multiply by four to get a year, then divide the yearly price by that number. At 3,081 dollars a year, a solo filing twice a month pays about 128 dollars per filing for Westlaw. A solo filing twenty times a month pays about 13. Both are buying the same product; only one of them is getting a bargain.

The picks, by the kind of solo practice you run

Litigator in one federal circuit: Westlaw Advantage, single circuit

If you are in court every week, pay for KeyCite. It is the check judges and malpractice carriers expect, and the single circuit plan is the cheapest published way to get it: from 256.75 dollars a month, sold online to firms of 1 to 10 attorneys and to new customers only. A three year term brings it to about 210.54 a month by our arithmetic, but that is a 7,579 dollar commitment, which is a lot to sign in your first year of practice.

Solo who mainly needs to find the right case: focused search

Most research time goes into finding the on-point decision, not validating it. That part does not need a 3,000 dollar seat. Our own tool, Cases, costs 29 dollars a month: you ask a question in plain English and read the US federal and state decisions it returns, with citations you can open. We do not have a citator and we say so. Pair it with library or bar access to a citator for the filings that need one.

Solo who wants AI research and a citator on a budget: midpage

midpage publishes 100 dollars a month, or 80 billed annually, with a two week trial and no card. It includes an AI citator that labels treatment as negative, caution or neutral and quotes its reasoning, plus agentic PACER access. It scored 75 in the Vals legal research benchmark, above the lawyer baseline. It is not KeyCite, but it is the closest published thing to it at under a third of the price, and we set the two side by side on midpage vs Westlaw.

Bar member: check what your dues already pay for

Fastcase states that it partners with over 80 national, state and county bar associations to provide research as a member benefit. What each bar funds varies a lot, which is why two solos in different states describe Fastcase so differently. Log in once before you buy anything; it may cover your statutory and basic case law needs on its own. Fastcase is now part of vLex and Clio, and our Fastcase bar benefit page tracks where the login and pricing pages went.

Personal injury solo with medical records: Paxton

Paxton publishes 499 dollars a month or 2,999 a year, which is half off for annual billing. The price is built around medical chronologies and billing summaries, not research. For a plaintiff solo who spends days building timelines from record sets, that can pay for itself. For anyone else it is a research tool at twice the price of Westlaw. Details on our Paxton AI pricing page.

Solo already running the practice in Clio: Clio Work

Clio Work puts vLex's Vincent AI inside Clio, reported at 199 dollars per user a month. The appeal is that research sits next to your matters. The problem for a buyer is that neither Clio nor vLex publishes the figure, so you are budgeting from reports. We explain what is knowable on Clio Work pricing.

Solo who drafts long briefs: Clearbrief

Clearbrief Solo is published at 300 dollars per user a month. It is a writing tool: select a sentence in Word and it finds the support in your own record, inserts the cite, and flags citations that do not resolve. It is not a research database, so it complements a search tool rather than replacing one.

Is Westlaw or Lexis better for a solo practitioner?

For a solo, Westlaw is easier to buy because it is the only one of the two with a published price. Content and citators are comparable: KeyCite and Shepard's do the same job. Lexis+ with Protégé has no rate card and is reported at about 128 to 494 dollars a month, so the practical move is to get a written Lexis quote at the same term and jurisdiction scope and compare it line for line with the Westlaw configurator total.

One point in Lexis's favor that is easy to miss: it sells Shepard's with the same weight Westlaw puts on KeyCite, and some solos simply read faster in one interface than the other. Use the trials. Westlaw Advantage has run seven days; Lexis+ with Protégé publishes two.

What do solo attorneys use for legal research?

Most US solos use a mix: a bar association benefit for everyday lookups, a paid tool for the work that matters, and a public library or law school terminal for the occasional citator check. That pattern is old. Fastcase was founded in 1999 as a low-cost alternative to Westlaw and LexisNexis and was sold largely through bar associations rather than to firms directly.

The gap is getting smaller. Several tools now publish prices under 100 dollars a month and offer an AI layer, a citator substitute, or both. What they do not offer is the depth of the Westlaw and Lexis editorial layer, the headnotes and Key Numbers built over decades. Whether that depth is worth 2,500 dollars a year is the real decision.

What a solo should not pay for

Do not buy anything on the strength of an old roundup. At least one page ranking for this search still recommends Casetext at 89 dollars a month. Casetext shut down on 1 April 2025 after Thomson Reuters bought it, and every casetext.com URL now returns HTTP 410, which means gone. We covered what replaced it in our best Casetext replacement guide.

Be careful with all states coverage too. The step from one circuit to all states plus federal on Westlaw costs 143 dollars a month at list, about 1,716 a year. If you only need other states' law for a survey once or twice a year, it can cost less to hire a freelance contract attorney for that project than to pay for coverage you open twice. And do not sign a three year term in your first year of practice to save 18 percent.

A setup that works for most solos

For a general civil litigation solo filing a few times a month, this is a sensible budget:

• Your bar benefit for statutes, rules and quick lookups (included in dues).
• A focused case law search tool for finding authority (about 350 to 1,200 a year, depending on whether you want an AI citator).
• Westlaw Advantage on one circuit only if your filing count justifies it (about 2,500 to 3,100 a year).

Whatever you buy, you still read every case before you cite it. Under ABA Formal Opinion 512 the verification duty stays with the lawyer, and the sanctions decisions of the last two years punished filings nobody read rather than the choice of tool. A search tool that gets you to the right decision fast is only half the job; opening the opinion is the other half.
