Legal software for lawyers in Argentina in 2026
Which four jurisdictions Custodio Legal watches by CUIJ, which are out of scope and why, and what the AI does with that as its input.
Custodio Legal operates in seven countries today, each behind its own plugin — what a plugin declares it supports is the only thing the platform promises there. In Argentina, what's sold is the AI: the daily CUIJ check is the input, not the product itself, and this page states precisely how far that input reaches.
What Custodio watches in Argentina
- Four jurisdictions, not twenty-four. The local courts of the City of Buenos Aires, Catamarca, Mendoza and Salta, all over the iurix system (
iol-api). Saying it this way, and not "Argentina," is the same honesty this product already requires in every other country. - The CUIJ's two written forms. Long in CABA and Catamarca, short in Mendoza and Salta — Custodio keeps whichever form belongs to each jurisdiction, never padded or trimmed.
- The Ley 27.399 calendar. The two judicial recesses, the holiday-transfer rule, and the distance increase of articles 155 through 158 of the CPCCN.
- The Ley 25.326 deadline, with both its units at once: ten calendar days for access, five business days for the rest.
- The BCRA's reference rate, as an informative figure under the USD price — never the billing currency.
- AI over your own documents. It answers with the source document cited for each answer, summarizes the ruling, states where the case stands, and drafts a filing in Word.
What is still out of scope
- Twenty of Argentina's twenty-four jurisdictions, including the federal Judiciary (Poder Judicial de la Nación) and the Province of Buenos Aires. Neither has a promised date.
- The Boletín Oficial and the Supreme Court's case law. It's not that nobody tried: the BORA's own
robots.txtforbids the edicts, notices and bankruptcy routes, and the CSJN's forbids its own search — it's the source's decision, and honoring it is part of operating in good faith. - Name search outside CABA. Catamarca, Mendoza and Salta expose the case by CUIJ but not a public party-name search.
- A verified bar roll. Bar membership is compulsory in Argentina, but no bar association publishes a roll Custodio can read today.
How it costs against local monitors
Argentine monitors that only connect PJN, MEV and EJE charge between USD 7.2 and 22.8 a month. Custodio, and Argentine legal AI in general at published prices, runs between USD 23 and 81 a month — it's a different category of product, and the price gap is the gap between a notice and a drafted answer over your own case file.
How to try it before deciding
- Create the free account, no card, and add a real case from one of the four covered jurisdictions, with its full CUIJ.
- Wait for the first automatic check and see whether it brought back anything from the case's history, not only what happens from now on.
- Upload a document from the file and ask the system something specific — the answer has to cite which document it came from.
- Compare the published price against how many open cases you carry today: the free plan includes 15 open matters.
Frequently asked questions about legal software in Argentina
Which Argentine jurisdictions does Custodio watch?
Four of twenty-four: the local courts of the City of Buenos Aires, Catamarca, Mendoza and Salta, over the iurix system. The federal Judiciary (Poder Judicial de la Nación) and the Province of Buenos Aires are out of scope, with no date promised for either.
Does Custodio watch the Boletín Oficial or the Supreme Court's case law?
No. The BORA's own robots.txt explicitly forbids the three routes of its Second Section, and the CSJN's forbids its case-law search — it's the source's own decision, not a technical gap on Custodio's side.
Can I search an Argentine case by a party's name?
Only in the City of Buenos Aires, one of the four jurisdictions Custodio reaches. Catamarca, Mendoza and Salta expose the case by CUIJ but not a public name search.
