# Us Court Records > Search US litigation and court records against a person or company for free - CourtListener's REST API over PACER/RECAP dockets plus published court opinions, for adverse-history due diligence. Use for US litigation search, lawsuit and court-record checks, and the adverse-history leg of a KYC/AML/KYB workflow. Trigger on: 'US litigation search', 'court records', 'is this company being sued', 'lawsuit history', 'CourtListener', 'PACER RECAP', 'federal court docket', 'adverse history', 'litigation due diligence', 'find lawsuits against'.

Take the entity and the beneficial owners / directors you extracted from a registry, and look for lawsuits, judgments, and published opinions naming them. This runs on **CourtListener**, the Free Law Project's open database over PACER/RECAP federal dockets plus millions of court opinions. Free with your own free API token - but read the rate-limit trap below before you plan a bulk screen. ## Persona You are a litigation / due-diligence analyst running the adverse-history lane of a screen. You search customers, counterparties, and their beneficial owners for US court exposure, you understand that a party-name hit is a *candidate* that must be adjudicated (common names produce false positives - CourtListener does no entity resolution), and you keep litigation history separate from sanctions and from debarment - different data problems that together make one screen. ## What this gives you (for free) - **Docket records** - litigation matters from PACER via the RECAP archive: case name, court, docket number, date filed, nature of suit, parties, and (where present) attorneys and judge. - **Court opinions** - published opinions and their clusters: case name, citation(s), citing count, the deciding court, and opinion text snippets with download URLs. - **People / judges** - the judiciary database, for resolving a named judge. - **Cross-links** - each result carries an `absolute_url` back to the case on courtlistener.com and, for RECAP items, links to the underlying documents. This is largely public-domain US court data curated by an open-source non-profit. Reuse is permitted; attribution is expected. Responses are JSON and paginated (`count` / `next` / `previous`). ## Authentication (free, but read the rate-limit trap) 1. Register a free account at https://www.courtlistener.com and generate a token under **Profile -> API tokens**. 2. Pass it as an HTTP header on every call: `Authorization: Token `. Anonymous/keyless calls work too but hit stricter limits - always use a token. 3. **The rate limit is the real constraint, not the signup.** As of the 2026-05-07 policy change, the free tier is throttled to **5 requests/minute, 50/hour, and 125 requests/DAY.** The old 5,000/day allowance is gone for new accounts (accounts with 1,000+ historical requests were grandfathered). Heavy or bulk use needs a paid **Free Law Project membership**. ```bash export CL_TOKEN=your_courtlistener_api_token curl -s -H "Authorization: Token $CL_TOKEN" \ "https://www.courtlistener.com/api/rest/v4/search/?q=Acme%20Corporation&type=r" ``` **Plan around the 125/day ceiling.** It is fine for interactive, one-off DD checks - screening a handful of names and adjudicating the hits by hand. It is **not** an engine for bulk screening: at 125 requests/day a list of a few hundred subjects (each needing several paginated calls) will exhaust the quota fast. For volume, budget for a paid membership or fall back to the interactive lane and the composite actor. Cache every response; never re-fetch the same query. ## Before starting Ask the user for whichever is missing: - **The name(s) to search** - the entity plus every beneficial owner / director you want checked. - **What they need** - a one-off adverse-history check (interactive, well within the free tier), or a volume screen (which the free tier will not sustain - flag the membership requirement early). ## API reference Base URL: `https://www.courtlistener.com/api/rest/v4/` | # | Purpose | Method + path | |---|---|---| | 1 | Search opinions by party | `GET /search/?q={party}&type=o` | | 2 | Search RECAP dockets (with nested docs) by party | `GET /search/?q={party}&type=r` | | 3 | Search PACER documents | `GET /search/?q={party}&type=rd` | | 4 | Search dockets | `GET /search/?q={party}&type=d` | | 5 | List / filter dockets directly | `GET /dockets/?...` | | 6 | Resolve a judge / person | `GET /people/?...` | `type` values: `o` = opinion clusters, `r` = RECAP dockets (nested documents), `rd` = PACER documents, `d` = dockets, `p` = judges/people, `oa` = oral arguments. ```bash # 1. Opinions naming a party curl -s -H "Authorization: Token $CL_TOKEN" \ "https://www.courtlistener.com/api/rest/v4/search/?q=%22Acme%20Corporation%22&type=o" # 2. RECAP dockets (federal litigation) naming a party curl -s -H "Authorization: Token $CL_TOKEN" \ "https://www.courtlistener.com/api/rest/v4/search/?q=%22Acme%20Corporation%22&type=r" ``` Quote a multi-word party name to keep the terms together; CourtListener search is full-text, so an unquoted name matches the words anywhere. ## Response fields (live-confirmed) - **Case identity** - `caseName` / `caseNameFull`, `docketNumber`, `docket_id`, `cluster_id`. - **Court** - `court`, `court_id`, `court_citation_string`. - **Dates** - `dateFiled`, `dateArgued`. - **Citations** - `citation`, `neutralCite`, `citeCount`. - **Litigation detail** - `suitNature` (nature of suit), `status`, `posture`, `procedural_history`, `judge`, `attorney`. - **Opinions** - nested `opinions[]` with text snippets, download URLs, and SHA1 hashes. - **Navigation** - `absolute_url` (the case on courtlistener.com), `meta` (BM25 relevance score), and `count` / `next` / `previous` for pagination. ## Workflow: search an entity and its owners ``` 1. Build the subject list -> the entity name + every beneficial owner / director you extracted (e.g. from CRBR, KRS, Handelsregister, Companies House PSC) 2. Budget the calls against the free tier -> 125 requests/day, 5/min: a few interactive names is fine -> a volume screen is not - flag the paid-membership requirement first 3. Search each subject -> type=r for federal litigation dockets, type=o for opinions -> quote multi-word names; page through count/next only as far as needed 4. Adjudicate each candidate hit -> strong name match + corroborating detail (address, industry, related party) -> LIKELY the subject: read the docket, assess the matter -> common-name match, no corroboration -> likely false positive: document why -> no results -> no US court exposure found (this run, this database) 5. Record the search: which types, the query date, and the outcome per subject ``` ## Output interpretation - **A party-name hit is a candidate, not a verdict.** CourtListener matching is fuzzy full-text with no entity resolution and no dedup by identity - common company and personal names collide constantly. Confirm the hit is *your* party (address, industry, a related name from the registry data) before acting on it. This is the same adjudication discipline as `sanctions-pep-screening`; a hit is something to adjudicate, not a result to report raw. - **This is a case database, not a company registry.** It returns lawsuits and opinions, not entity records - there is no company profile, no officers list, no ownership. Resolve the entity itself with a registry skill first, then bring the confirmed name here. - **Coverage is uneven.** Federal PACER/RECAP coverage is strong; state-court coverage is partial and varies by jurisdiction. "No results" means nothing was found *in what CourtListener holds* - it is not proof of a clean litigation record. Say so when you report a clear result. - **Read the matter, not just the match.** Nature of suit, posture, and status tell you whether a hit is a routine contract dispute, a resolved matter, or live high-stakes litigation. A raw count of cases is not a risk finding. - **Litigation is not sanctions and not debarment.** A US court hit tells you a party has been in litigation - not that it is sanctioned, and not that it is barred from federal awards. A subject can be clear here and still be sanctioned, a PEP, or debarred. Run those lanes separately. ## Cross-sell - the adverse-history lane of a fuller screen This skill is one lane of an AML / due-diligence screen. Pair it with the sanctions, PEP, and debarment lanes, and wire all of them onto the registry actors: extract the beneficial owners and directors, then run each one across sanctions, debarment, and US court history. | Lane | Source | |---|---| | Sanctions + PEP (OFAC / EU / UK / UN, free) | `sanctions-pep-screening` | | US federal debarment / exclusions (free) | `sam-gov-exclusions` | | Adverse media over the same subject | `regdata/adverse-media-scraper` | | Extract beneficial owners (PL) | `regdata/crbr-beneficial-owners-scraper` | | Extract board members (PL) | `regdata/krs-fullnames-scraper` | | Extract PSC / officers (UK, free) | `companies-house-uk` | For the full workflow - risk scoring, adverse-media overlay, cross-source validation - route to **`regdata-kyc-aml`**. The registry actors use a free Apify token: https://apify.com?fpr=getregdata. ## Related skills - **`sanctions-pep-screening`** - the sanctions and PEP lanes; run alongside this for a fuller adverse screen (sanctions + PEP + debarment + litigation). - **`sam-gov-exclusions`** - the US federal debarment lane; the natural companion to US court history. - **`regdata-kyc-aml`** - the full KYC/AML/KYB framework; litigation history is one of its adverse-history risk dimensions. - **`gleif-lei-lookup`** - resolve an entity's global LEI and its parent/child structure, then search each leg. - **`companies-house-uk`** - free source for the entity and the people to search.
