Please read carefully. These Terms and Conditions of Use govern the issuance of security folios and QR codes through the «LITXIGNIA · Security folios» solution, as well as the public lookup of their authenticity. The issuing organization and its operators accept them by using the solution; whoever verifies a folio accepts them by looking it up. This English version is provided for reference only; in the event of any discrepancy, the Spanish version shall prevail.
01Parties and acceptance
1.1. LEGAL IN TECH, S. de R.L. de C.V. («LEGAL IN TECH») owns the technology solution «LITXIGNIA · Security folios», which assigns each document a unique folio, a QR code and a double digital fingerprint, records its issuance, validation, anchoring and, where applicable, voiding, and allows third parties to verify its authenticity (the «Solution»). AMERICA LEGAL BUFETE, S.C. («AMERICA LEGAL®») provides the professional services related to it.
1.2. Acceptance is given by electronic means in accordance with the Federal Civil Code and articles 89 to 94 of the Commercial Code, and is recorded in the log.
02Definitions
- Issuer: the organization that generates folios for the documents it signs or issues.
- Operator: the person authorized by the Issuer to generate, validate or anchor folios.
- Folio: the unique identifier assigned to a document in its final version, with its QR code.
- Fingerprint: the result of applying the SHA-256 and SHA3-256 functions to the file; any change in the file produces a different fingerprint.
- Anchoring: the recording of the fingerprint of the signed or final version of a document.
- Verifier: any person who looks up a folio or compares a file against its fingerprint.
03What LITXIGNIA evidences
3.1. A successful verification evidences that the folio was issued by the Issuer shown in the lookup, on the recorded date, and, when a file is compared, that such file is bit-for-bit identical to the anchored document.
3.2. LITXIGNIA does not evidence the truthfulness of the document's content, the capacity or authority of whoever signs it, or the validity of the legal act it contains. Nor does it replace the advanced electronic signature, notarial attestation or the data message preservation certificate under NOM-151-SCFI-2016; it is an additional layer of authenticity that may coexist with them.
3.3. A printed document keeps its folio and QR, but fingerprint comparison is only possible with the original electronic file.
04Issuance, validation and anchoring
4.1. The Issuer is responsible for assigning folios only to its own documents or to documents it is authorized to issue, and for the truthfulness of the data entered (signatory, recipient, subject matter and exhibits).
4.2. Each folio records who generated it and who validated it. The Issuer must anchor the signed or final version; until it does so, the lookup will indicate it.
4.3. Folios are chained through successive seals, so that the alteration of a previous record is detectable.
05Voiding and replacement
The Issuer may request the voiding or replacement of a folio stating the reason. The request and its resolution are kept in the log and the public lookup will show the folio as VOIDED or REPLACED, with the reference to the folio that replaces it. No folio is deleted.
06Public verification
6.1. Looking up a folio is free of charge and does not require an account. The Verifier undertakes to use it only to verify the authenticity of documents it legitimately has before it.
6.2. It is prohibited to look up folios in bulk or in an automated manner, to attempt to infer third-party folios or to use the lookup information for purposes other than verification.
07Comparison requests
Whoever requires a formal comparison, a certificate or a clarification regarding a folio must submit a request and evidence their identity, standing and legal interest. The Issuer and LEGAL IN TECH may deny the request when these elements are not evidenced or when the information is confidential.
08Obligations of the Issuer and its operators
- Safeguard their credentials and signing keys; answer for the folios generated with them.
- Not generate folios for forged, altered or third-party documents.
- Address the comparison requests that correspond to them.
- Immediately inform LEGAL IN TECH of any unauthorized use.
09Evidentiary value
Folios, fingerprints and logs are data messages under the Commercial Code. Their evidentiary weight will be assessed based on the reliability of the method by which they were generated and kept. LEGAL IN TECH does not guarantee the outcome of any proceeding.
10Intellectual property
The Solution, its code, design, folio format and databases are works protected by the Federal Copyright Law and the Federal Law for the Protection of Industrial Property. The names LEGAL IN TECH and LITXIGNIA, as well as their logo, seal and GA icon, are distinctive signs of LEGAL IN TECH, S. de R.L. de C.V., and AMERICA LEGAL® is a trademark of its owner. These Terms do not grant any license for their use. Reproducing the folio format or the QR on documents not issued with the Solution is prohibited.
11Liability
11.1. LEGAL IN TECH is liable for the correct calculation of the fingerprints and the integrity of its records. It is not liable for the content of the documents, for folios generated with the Issuer's credentials or for decisions that third parties make based on a lookup.
11.2. Except in the case of willful misconduct or gross negligence, the total liability of LEGAL IN TECH toward the Issuer is limited to the amount paid in the twelve months prior to the event giving rise to it.
12Availability and retention
LEGAL IN TECH will endeavor to keep the public lookup continuously available. Records of folios, fingerprints and anchorings are kept for as long as their evidentiary value subsists, even after the service with the Issuer has ended, so that documents already issued remain verifiable.
13Amendments
LEGAL IN TECH may amend these Terms. Amendments will be published on this page with their update date and will not affect the verifiability of folios already issued.
14Governing law and jurisdiction
These Terms are governed by the federal laws of the United Mexican States. For their interpretation and enforcement, the parties submit to the competent courts of Mexico City and waive any other jurisdiction.
