Labor procedure runs on one consolidated code, not several — but that one code is 83 years old and was substantially rewritten in 2017. This page shows exactly which articles ground each process, the chapter-level mistakes a SINALEVI line-read caught, and the one thing we're still honestly unsure about.
Código de Trabajo Ley 2 (1943) — 725 articlesProcedural reform Ley 9343, in force since 25 Jul 2017 — merged into Ley 2, not separateSINALEVI_VERIFIEDnot yet ATTORNEY_VERIFIED
Quick background
Costa Rica's labor litigation system runs on a single statute: the Código de Trabajo, enacted as Ley N.º 2 in 1943 — one of the oldest active codes in the Costa Rican legal system. That number is misleading if read as "unchanged since 1943": how a labor case actually moves through a courtroom today was substantially rewritten by the Reforma Procesal Laboral, Ley N.º 9343, in force since July 25, 2017, which replaced a largely written procedure with an oral, hearing-driven model.
The detail that matters most for how our system is built: Ley 9343 is not a parallel code you'd cite separately. Unlike the civil, contencioso-administrativo, or familia branches — which ground against two, three, or four distinct statutes at once — labor is structurally simpler. Ley 9343's reforms were merged directly into the text of Ley 2 itself; SINALEVI publishes them as one 725-article document with the 2017 rewrite already baked into its numbering. One code to ground against, not several — even though that code is old and has been amended many times.
That structural simplicity didn't make the mapping easy. An 83-year-old, heavily amended code is exactly where an article number from an outdated summary — or a language model's general training — can point at the wrong provision, or a chapter renumbered out from under it.
LEY 2 + 9343
This page describes source grounding, not legal advice. It tells you what our system reads and how thoroughly it's been checked — including places our own earlier draft was wrong. It does not tell you how the law applies to your facts. Nothing here substitutes for review by a licensed Costa Rican abogado laboralista.
Source alignments, by process
Four procedural tracks are modeled, all drawn from Título Décimo (Jurisdicción Especial de Trabajo) plus the substantive articles each reaches back into. Every citation below is Código de Trabajo, art. X — there's only one code in play — but article numbers are precise because, as on our other branches, several were wrong before verification.
Proceso Ordinario Laboral
Título Décimo, Cap. VI — arts. 495–537, + Cap. XI arts. 583–586
SINALEVI_VERIFIED
The default track for a labor dispute — most wrongful-termination and unpaid-wages claims run through it. It follows the same oral, hearing-driven shape the 2017 reform gave Costa Rican procedure generally: a written demand, a short window to answer, one or two structured hearings, a judgment appealable on a tight clock.
The court's own duty to promote a conciliated settlement before trial
Contestación / oposición
497, 498, 500
The employer's answer
Sentencia anticipada
506–510
Early judgment on default, non-answer, or an improper claim
Audiencia — fase preliminar
512, 513, 517
Case management, conciliation attempt, framing disputed facts
Audiencia — fase complementaria / juicio
518, 519–522
Evidence and closing argument; separate session if complex
Sentencia
518 inc. 4, 528, 537
Oral/dispositive ruling and its deadlines
Recursos (apelación / casación)
583, 584, 586
Appeal and cassation
Correction — sentencia is not art. 466
An earlier draft assumed art. 466 governed dictado de sentencia. It doesn't — art. 466 covers días y horas hábiles, business days and hours for procedural acts, a housekeeping provision. The real sentencia provisions are art. 518, inciso 4 (the oral/dispositive ruling) and art. 537 (its deadlines).
Correction — the demand's requirements are not art. 462
An earlier draft treated art. 462 as listing what a labor complaint must contain. It governs firmas en actos escritos — signatures on written filings, a general formality provision. The real demand-requirements article, with its ten specific requisitos, is art. 495.
Correction — three SINALEVI-PENDING gaps closed
The contestación deadline, hearing structure, and appeal provisions were previously unconfirmed. Now closed: the answer deadline is a 10-day peremptory term (art. 497); the hearing runs in two phases — preliminar and complementaria/juicio — under arts. 512, 517, 518, 519–522; the appeal window is 3 days, cassation 10 days, under arts. 583, 584, 586.
Related substantive law: cross-cutting principles at arts. 420–422; carga de la prueba (arts. 478, 500, 35); causas justas de despido (art. 81) and consequences of dismissing without proving cause (art. 82).
Fuero Especial y Proceso Sumarísimo
Título Décimo, Cap. VII § II — arts. 540–547 + sustantivo 94, 363–367, 404
SINALEVI_VERIFIED
For workers in a legally protected status — pregnancy, union membership, whistleblower and anti-discrimination protections — where ordinary-track timelines are too slow to prevent irreversible harm. Deliberately fast: a filing can be moving within 24 hours.

A correction worth surfacing for its honesty, not its confidence
An earlier draft schema referred to a standalone article "94 ter" as the basis for the administrative pre-authorization step. Having now read the full consolidated text (SINALEVI v. 62/62), we can't confirm "94 ter" exists as a separate article — it may simply be embedded within art. 94 itself. We're flagging this as an open, LOW-confidence item and using art. 94 as the safe anchor until it's resolved, rather than rounding it off into false certainty. LOW
Related substantive law: fuero sindical stability (arts. 363, 367); the discrimination catalog (art. 404) — rated independently HIGH confidence, checked literally against SCIJ.
Ejecución de Sentencia Laboral
Título Décimo, Cap. X — arts. 571–577
Largest correction in this branch
What happens after a worker wins: converting a final judgment into an actual payment, or actual reinstatement, when the employer doesn't comply voluntarily.
Stage
Art.
Covers
Solicitud de ejecución de la sentencia firme

Liquidación y cobro de extremos condenados
571, 572
Calculating and collecting amounts owed; art. 572 sends asset-seizure mechanics into supletorio CPC — see below
Cumplimiento de la orden de reinstalación
573–577
8-day compliance window, notarial/MTSS certification, back pay, fines for refusal
Correction — the single largest fix in this branch
An earlier draft cited arts. 582–583 as the execution chapter. They are not. Those articles belong to an entirely different chapter — Capítulo XI, covering medios de impugnación raised mid-hearing and the taxative list of appealable orders, not enforcement at all. The actual execution chapter is Capítulo X, arts. 571–577 — reinstatement compliance, back-pay, and fines for refusal to reinstate. A full chapter's worth of provisions had been attributed to the wrong part of the code.
Related substantive law: art. 572's supletorio link to Código Procesal Civil enforcement mechanics — see the guardrail axes below; the reinstatement-refusal fine under art. 398.
Medidas Cautelares Laborales
Título Décimo, Cap. V § V — arts. 489–494
SINALEVI_VERIFIED
Provisional measures a worker can seek before or during a case — most importantly preventive embargo and arraigo — to keep an employer from becoming judgment-proof or leaving the country before a claim is resolved.
Stage
Art.
Covers
Solicitud de medida cautelar
489–493
Labor-specific cautionary measures, distinct from general civil ones
Resolución de la medida cautelar
491, 492, 493, 494
Embargo without bond; arraigo; provisional reinstatement as a cautionary measure
Control del plazo pre-procesal
491, 492
Demand must follow within 10 days (embargo) or 3 days (arraigo) — high-severity deadlines
Worth naming as a design point, not a correction
Art. 494 is deliberately tagged under both pipelines below. That isn't an oversight — it reflects the statute itself: when a court orders provisional reinstatement as a cautionary measure, art. 494 sends that order directly into the execution chapter's mechanics (arts. 571+). Rather than force a single article into one silo, our system supports tagging it under both, because the statute genuinely treats it as belonging to both.
→Art. 494 bridges medidas cautelares and ejecución directly — provisional reinstatement remits into the execution chapter.
→Art. 572 sends patrimonial enforcement in ejecución out of the Código de Trabajo entirely and into Código Procesal Civil mechanics.
→Arts. 420–422 and 428 — jurisdiction/competence, principio protector, pro operario, supletory application — sit upstream of and apply across all four tracks.
A distinctive feature: the guardrail axes
Beyond article-to-process mapping, the labor schema encodes something the civil and contencioso branches don't need in the same way: framing rules tied to specific articles that our retrieval system is required to respect, not just informed by.
carga_probatoria — arts. 478, 500, 35 — the non-negotiable one
Costa Rican labor procedure places the burden of proof asymmetrically by design: the worker has to prove they performed the work; the employer bears the burden of proving just cause for a dismissal and must produce its own personnel records to do so. This is the structural core of carga de la prueba in labor law — our system treats it as a hard rule, not a preference. Retrieval must never surface or rank content in a way that inverts that framing.
principio_protector — arts. 420, 422
The protective principle — that labor procedure exists to correct a structural imbalance between employer and worker — runs through the whole of Título Décimo and is tagged on the transversal principios chunks every one of the four pipelines draws from.
Labor procedure runs on unusually tight, high-stakes deadlines: 10 days to answer a complaint, 10 days to request preventive embargo, 3 days for arraigo, 3-day appeal windows (cassation at 10 days). Flagged for elevated deadline alerting rather than treated as routine dates.
suppletorio_cpc — arts. 428, 572
When enforcing a labor judgment moves into asset-seizure or liquidation mechanics, the Código de Trabajo doesn't repeat that machinery — it explicitly borrows it from the Código Procesal Civil. A complete answer about labor-judgment enforcement sometimes has to pull from both this branch's corpus and the civil branch's execution corpus — a concrete example of how our jurisdiction corpora interconnect rather than standing entirely apart.
How to verify this yourself
We'd rather an expert reader check our work than take it on faith. Everything above traces to the Sistema Nacional de Legislación Vigente (SINALEVI), published through Costa Rica's Procuraduría General de la República at pgrweb.go.cr/scij.
For the Código de Trabajo: full consolidated text under SCIJ normativa search, law number 2 (internal id nValor2=8045) — currently 725 articles, version stamped "62 de 62 del 04/11/2025." Ley 9343's own SCIJ ficha (nValor2=80985) is kept only as a historical/metadata anchor — its reforms are already inside the Ley 2 text above, so it isn't a separate ingest target.
What "verified" means here — at two grains
We use the same five-tier confidence vocabulary across every jurisdiction branch — HIGH / MEDIUM / LOW / SINALEVI_VERIFIED / ATTORNEY_VERIFIED — but on this branch it shows up at two different grains: an overall chunk-level tag on every statutory record (the metadata schema's worked example shows verification_confidence: "SINALEVI_VERIFIED"), and a separate, per-correction confidence rating in the internal drift-closure table.
HIGH
Most fixes described on this page — the art. 466/462 reassignments, the ejecución chapter fix, the contestación/audiencia/recursos closures.
MEDIUM
The fuero sumarísimo stages at arts. 544–547.
LOW
The "94 ter" question — the one item on this page we're explicitly not claiming to have resolved.

The mapping on this page has reached SINALEVI_VERIFIED for the corrected article ranges. It has not yet reached ATTORNEY_VERIFIED — a deliberate, separate gate before any corrected article number is used in a production citation, pending sign-off from a licensed Costa Rican labor attorney against a dedicated verification checklist, mirroring the civil branch's gate. If you're a practicing abogado laboralista and something here doesn't match your own reading of the consolidated text, we want to hear about it.
