Signing documents from a smartphone may feel informal — but with the right tools, it’s just as legally valid and secure as signing on paper. Yousign ensures that every signature made on mobile meets the highest standards for legal compliance and data protection.

Yousign’s mobile signatures comply with the eIDAS regulation (EU Regulation No. 910/2014), which defines the legal framework for electronic signatures in all EU Member States.

This means that:

• Mobile electronic signatures are legally recognised across the EU and UK
• Contracts signed on mobile with Yousign carry the same legal weight as those signed on desktop
• Advanced Electronic Signatures (AES) used via Yousign include identity verification, integrity protection, and non-repudiation

You can sign business agreements, HR documents, sales contracts, and more from your phone — all with full legal certainty.

Yousign applies the same strict security protocols to mobile signatures as it does on desktop:

• End-to-end encryption of documents and personal data
• Two-factor authentication (2FA) for secure signer identification
• Tamper-proof audit trail recording every action taken during the signing process
• Time-stamped certificates to prove the signature date and time

Every signed document includes:

• A detailed audit trail (who signed, when, and how)
• A certificate of completion with metadata
• Proof that the document has not been altered after signing

These records make Yousign’s mobile e-signatures legally admissible in court and suitable for regulated industries.

Whether you're signing from your office or your phone, Yousign ensures that your documents are protected, traceable, and fully compliant with European law.

To get the most out of electronic signatures on mobile — and to ensure every signed document is secure, valid, and compliant — it's essential to follow a few best practices. These steps apply whether you're managing internal approvals, client contracts, or sensitive business documents.

Not all documents require the same level of signature. Before signing:

• Identify whether the document needs a Simple, Advanced, or Qualified Electronic Signature
• Ensure the electronic signature is acceptable for the document type under local or EU law
• For regulated documents (e.g. in legal, financial, or public sectors), use a compliant platform like Yousign

When in doubt, opt for an Advanced Electronic Signature (AES) for strong legal protection.

Avoid free or unverified apps that lack security and compliance guarantees. Instead:

• Use a platform that is certified under the eIDAS regulation
• Ensure the app or mobile browser solution offers features like identity verification, encryption, and audit trails
• Rely on a Qualified Trust Service Provider for high-value or cross-border transactions

Yousign is fully compliant and suitable for business and legal use across Europe.

Make sure all employees and collaborators:

• Know how to access and use the electronic signature tool on their smartphones
• Understand when and how to use signatures in a secure and compliant way
• Avoid sharing credentials or using personal email addresses for official documents

A short onboarding session can drastically reduce user errors and legal risks.

For legal protection and operational efficiency:

• Store signed documents in a secure, searchable archive
• Use a cloud-based platform like Yousign that offers document tracking and retrieval
• Set internal policies for retention periods, especially for HR or contractual documents

With Yousign, all signed documents are stored automatically with full access control and legal evidence.
