    Use this when the user wants to add or correct a fact in a draft that prepare_legal_notice created in this conversation (a forgotten duration, another date, a misspelt name): send its draftId and editToken, the formality and only the fields to change; the others stay as they are. Send decisionDate and effectiveDate together, and each officer with its type. Returns the new notice text and what the form still requires; the link already given keeps opening the draft, until the same expiry. Do not use for a draft the user has already saved on legalone.fr (it is then theirs, and is changed on the form), nor to start another notice: use prepare_legal_notice. Same privacy rules as prepare_legal_notice.

  • prepare_legal_noticechangeddescription, input schema
    before

    Use this when the user wants LegalOne to prepare their legal notice for an existing company (registered office transfer, change of manager or president, name, corporate purpose, share capital, duration, early dissolution, liquidation closure): creates a draft on legalone.fr from the SIREN and the facts the user gave, and returns the notice text, what is left to complete and a link, valid 7 days, that opens the pre-filled form. The user reviews, completes and pays on legalone.fr; nothing is published or paid here. Do not use for a company creation, and do not send home addresses, birth dates or contact details: they are completed on legalone.fr.

    Use this when the user wants LegalOne to prepare their legal notice: a change to an existing company (registered office transfer, change of manager or president, name, corporate purpose, share capital, duration, early dissolution, liquidation closure), from its SIREN and the facts of the decision; or the creation of a company (SAS, SASU, SARL, EURL, SCI and the other forms of which_legal_notice), from its articles of association, without SIREN. Creates a draft on legalone.fr and returns the notice text, what is left to complete and a link, valid 7 days, that opens the pre-filled form. `missing` lists what the form still requires: the draft is complete only when it is empty; otherwise tell the user what to add on the form (for instance the company's duration, from the articles of association, when the notice prints it). Each call creates a new draft: gather all the facts first; to add or correct a fact afterwards, call update_legal_notice_draft with the draftId and editToken returned here, rather than calling again. The user reviews, completes and pays on legalone.fr; nothing is published or paid here. Do not use for a sole trader, and do not send birth dates, nationalities or contact details. Home addresses are sent only for the officers of a company being created, as its notice publishes them; for a change, they are completed on legalone.fr.

  • get_companychangedtitle, description, annotations

    Use this when you know a company's SIREN and the user wants its official identity, or wants to pre-fill a business customer's onboarding form: name, active or ceased, legal form code, NAF code, creation date, head office, establishments, share capital and current officers (name and role only), with sources and update date. Do not use for financial statements, beneficial owners, contact details or people searches, or as a regulatory identity check (KYC); that data is not provided.

Tools (12)

get_bodacc_noticeread-onlyUse this when you have a BODACC notice identifier (for example from list_bodacc_notices) and need its detailed content. Personal details such as birth dates and home addresses are never included. Do not use to look for notices without an identifier.
get_companyread-onlyUse this when you know a company's SIREN and the user wants its identity, or wants to pre-fill a business customer's onboarding form: name, active or ceased, legal form code, NAF code, creation date, head office, establishments, share capital and current officers (name and role only), with sources and update date. Do not use for financial statements, beneficial owners, contact details or people searches, or as a regulatory identity check (KYC); that data is not provided.
get_establishmentread-onlyUse this when the user gives a SIRET (14 digits) and wants that establishment's address, activity code, status and whether it is the head office. Do not use to find all establishments of a company; get_company lists them.
get_legal_notice_priceread-onlyUse this when the user asks how much a legal notice (annonce légale) costs for a formality in a French department: returns the exact regulated price excluding and including VAT, set by ministerial order and identical in every authorised newspaper of that department. Notices priced by the character need their text for an exact amount; without it the rate per character is returned. Do not use to compare newspapers or providers: the price is set by law and is the same everywhere.
get_next_stepsread-onlyUse this when the user has published, or is about to publish, a legal notice and asks what comes next: the filing on the one-stop shop for business formalities (guichet unique, INPI), deadlines, what the court registry does (BODACC) and the documents to prepare for that formality. Do not use as a substitute for the official checklist shown by the one-stop shop when filing.
list_bodacc_noticesread-onlyUse this when the user asks what was officially published about a company (registration, changes, sale of business, insolvency proceedings, removal) and you know its SIREN: returns the latest BODACC notices, newest first, with links to the official text. Do not use to search notices by person, court decision type or region.
list_company_documentsread-onlyUse this when the user wants to know which deeds or annual-accounts filings a company has registered (title and dates), with a link to download them from the INPI. Do not use to read financial figures; the documents themselves are not returned.
prepare_legal_noticeUse this when the user wants LegalOne to prepare their legal notice: a change to an existing company (registered office transfer, change of manager or president, name, corporate purpose, share capital, duration, early dissolution, liquidation closure), from its SIREN and the facts of the decision; or the creation of a company (SAS, SASU, SARL, EURL, SCI and the other forms of which_legal_notice), from its articles of association, without SIREN. Creates a draft on legalone.fr and returns the notice text, what is left to complete and a link, valid 7 days, that opens the pre-filled form. `missing` lists what the form still requires: the draft is complete only when it is empty; otherwise tell the user what to add on the form (for instance the company's duration, from the articles of association, when the notice prints it). Each call creates a new draft: gather all the facts first; to add or correct a fact afterwards, call update_legal_notice_draft with the draftId and editToken returned here, rather than calling again. The user reviews, completes and pays on legalone.fr; nothing is published or paid here. Do not use for a sole trader, and do not send birth dates, nationalities or contact details. Home addresses are sent only for the officers of a company being created, as its notice publishes them; for a change, they are completed on legalone.fr.
search_addressesread-onlyUse this when the user gives a French postal address, complete or partial, and wants it checked, completed, normalized or geolocated: returns the best Base Adresse Nationale matches with house number, street, postcode, city, INSEE municipality code, coordinates and a match score, plus whether the best match is reliable. Do not use for addresses outside France, for finding who lives or works at an address, or for listing the companies at an address.
search_companiesread-onlyUse this when the user names a French company (or gives a SIREN or SIRET) and you need to identify it: returns up to 20 matches with name, SIREN, status, legal form code, NAF code and head-office city. Name matching is a prefix match on the official name. Do not use for people, officers or shareholders, and do not use it to list companies by sector or area.
update_legal_notice_draftUse this when the user wants to add or correct a fact in a draft that prepare_legal_notice created in this conversation (a forgotten duration, another date, a misspelt name): send its draftId and editToken, the formality and only the fields to change; the others stay as they are. Send decisionDate and effectiveDate together, and each officer with its type. Returns the new notice text and what the form still requires; the link already given keeps opening the draft, until the same expiry. Do not use for a draft the user has already saved on legalone.fr (it is then theirs, and is changed on the form), nor to start another notice: use prepare_legal_notice. Same privacy rules as prepare_legal_notice.
which_legal_noticeread-onlyUse this when a French company or its adviser describes a corporate event (creation, registered office transfer within or outside the department, change of manager or president, name, corporate purpose, share capital, legal form, duration, dissolution, liquidation closure, sale of a business…) and needs to know which legal notices are mandatory, how many, in which department, on what legal basis and at what price. The answer comes from a fixed table of rules; when it needs one more fact, it returns a question instead of a guess. Do not use for court-ordered insolvency notices or for legal advice on whether to take the decision.
