# Legale.io – E-Signature validity, trust model & compliance

## **1. Overview**

Legale.io provides an end-to-end electronic signature solution designed to ensure **legal validity, identity assurance, document integrity, and full auditability**, aligned with international standards and enterprise compliance requirements.

The platform does not rely solely on a visual signature. Instead, it builds a **complete evidentiary framework** that supports enforceability in legal and regulatory contexts.

## **2. Legal validity framework**

Legale.io’s signature model is based on four core legal principles:

- **Authentication:** The identity of the signer is verified using multiple mechanisms.
- **Integrity:** Signed documents are cryptographically protected against modification.
- **Non-repudiation:** Evidence ensures the signer cannot deny participation.
- **Traceability:** Full audit logs are maintained across the document lifecycle.

This approach aligns with global frameworks such as:

- **eIDAS (EU Regulation)**
- **Electronic signature laws in LATAM (e.g., Ley 19.799 in Chile)**
- International best practices for digital evidence

## **3. Digital certificate & trust infrastructure**

Legale.io uses digital certificates with the following characteristics:

- Issued by a **European Union accredited Certification Authority**
- Included in the **European Union Trusted Lists (EUTL)**
- Certificate is issued to **Legale Sign LLC (legal entity)**

This implies:

- The issuing authority has performed **formal validation of the organization**
- The certificate operates under a **recognized trust framework**
- Legal representatives of the company are responsible for its usage

This trust model ensures compatibility with **globally recognized digital trust standards**.

## **4. Signature process (End-to-end flow)**

### **4.1 User binding**

- A **unique, non-transferable link** is sent to the signer’s email
- The user accesses and interacts directly with the document
- This establishes a strong link between identity and action

### **4.2 Document generation**

- Documents are dynamically generated (Smart Documents)
- Based on user-provided data
- Timestamped and stored with full metadata

### **4.3 Signature execution**

- Signatures are **embedded directly into the PDF**
- Each signature creates:
  - A unique signature record
  - Cryptographic validation
  - Signer identification

### **4.4 Identity verification**

Depending on configuration, Legale.io supports:

- Video-based identity verification
- ID document validation
- Email-based identity binding
- Evidence capture (including audiovisual)

### **4.5 Audit trail & logging**

The system records:

- Document delivery timestamp
- Access and viewing events
- Signature timestamps
- User identity per action

All logs are **immutable and auditable**.

### **4.6 Independent verification**

Each document includes a **unique GUID**, allowing:

- Independent validation of authenticity
- Full audit trail access
- Document verification without platform dependency

## **5. Document integrity controls**

- Documents are protected using **cryptographic hashing**
- Any post-signature modification invalidates the signature
- Validation tools (e.g., Adobe Acrobat) confirm:
  - No changes after signing
  - Valid certificate chain
  - Trusted timestamp

## **6. Evidence package (Available to clients)**

For every signed document, Legale.io provides:

- Signed PDF document
- Digital signature certificate
- Full audit trail (timestamps, actions, users)
- Identity verification evidence (if enabled)
- Signature event logs
- GUID-based verification access

This constitutes a **complete digital evidence file**, suitable for legal, compliance, and audit purposes.

## **7. Compliance & security alignment**

Legale.io aligns with enterprise security and compliance frameworks:

### **Information Security**

- ISO 27001-aligned controls (managed via Drata)
- Continuous security monitoring (e.g., vulnerability management, ethical hacking)
- Secure cloud infrastructure (Microsoft Azure)

### **Access & identity**

- SSO via Azure Entra ID (OIDC + PKCE)
- Role-based access control (RBAC)

### **Data protection**

- Encryption in transit (TLS 1.2+)
- Encryption at rest
- Secure audit logging

### **Audit & monitoring**

- Full traceability of all document actions
- Centralized logging and monitoring
- Exportable audit evidence

## **8. Why Legale.io E-Signatures are legally enforceable**

Legale.io ensures enforceability because it can demonstrate:

| Requirement | How Legale.io Solves It |
| --- | --- |
| Who signed | Identity verification + user binding |
| What was signed | Immutable PDF + hash validation |
| When it was signed | Timestamped audit logs |
| How it was signed | Digital certificate + full traceability |

---

## **9. Key takeaway for enterprise clients**

Legale.io does not only capture a signature.

It generates a **complete, verifiable, and auditable legal evidence package**, ensuring that every document can withstand:

- Legal disputes
- Regulatory audits
- Internal compliance reviews

## **10. Optional supporting evidence**

Available upon request:

- ISO 27001 documentation / Trust Center (Drata)
- Penetration testing reports
- Security policies
- Architecture diagrams
- API documentation ([https://doc.legale.io/docs/v1/overview](https://doc.legale.io/docs/v1/overview))

## **11. Executive summary**

Legale.io provides legally enforceable electronic signatures by combining:

- EU-accredited digital certificates (EUTL)
- Strong identity verification mechanisms
- Immutable document integrity controls
- Full audit trail and traceability
