With the full implementation of Organic Law 1/2025 on the Efficiency of Justice, real estate agencies and owners can no longer go directly to court in cases of non-payment of rent, claims for damages to the property, return of the deposit, breach of contractual obligations or disagreements about repairs and maintenance.

The law requires attempting an ADR (Appropriate Means of Dispute Resolution) as a mandatory prerequisite to any civil lawsuit.

How can this procedure be completed quickly, cheaply, and with full legal guarantees before a judge?

The answer lies in certified electronic communication and digital signatures, an area where XolidoSign Professionalis establishing itself as the indispensable strategic ally.

1. Certified Electronic Communication with Absolute Traceability

When a real estate agency sends a MASC agreement proposal or a Binding Offer through our platform, it's not just sending a regular email. XolidoSign automatically generates an Evidence Report with complete traceability of the communication.

• Identification and Logs: Records email addresses, source and destination IPs, and delivery logs on the tenant's server.
• Content Integrity: Ensures, through hashing algorithms, that the text of the request and attached documents have not been tampered with, serving as documentary evidence.

2. Closing the agreement using Biometric Signature or Certificate

If the ADR process is successful and the tenant accepts the proposal (a payment plan, a mutually agreed-upon return of keys, etc.), the conflict should be resolved with full guarantees.

XolidoSign Professionalallows you to formalize the agreement immediately using different types of digital signatures. For tenants without a digital certificate, biometric handwriting from any smartphone or tablet captures the signer's handwriting data (pressure, speed, stroke), giving the document legal validity as a signature with legal standing.

3. Efficiency and cost control for real estate

Unlike cumbersome postal processes, XolidoSign Professional stands out for its versatility:

• It's a cloud-based solution, requiring no complex installations.
• It allows for complete cost control, eliminating fees for registered mail or other individual delivery charges.
• It optimizes agency time: what used to take days to process by post can now be managed and certified in minutes.

A smart workflow in the face of conflict

Thanks to XolidoSign, a real estate agency's protocol for handling situations such as rent defaults is automated and simplified:

1. Issuance: The agency drafts the Confidential Binding Offer (BBA) and sends it electronically via XolidoSign.
2. Certification: XolidoSign acts as a neutral Trusted Third Party, issuing a certificate that proves the tenant has received the offer.
3. Resolution:
   1. If there is an agreement: The parties digitally sign the transactional document on the platform, making it legally binding.
   2. If there is no agreement: The XolidoSign Evidence Report is attached to the legal claim to demonstrate to the judge that the procedural requirements of Organic Law 1/2025 were met.

UsingXolidoSign Professional not only guarantees strict compliance with MASC regulations, but also provides a distinct added value to its owner clients.

Digital transformation has changed the way companies and organizations formalize agreements, report information, and manage their internal processes. Electronically signed contracts, online acceptance of terms and conditions, certified communications, and digital authorizations are now part of everyday business operations.

However, in this new digital environment, a fundamental question arises: how can we subsequently prove that a specific action actually took place?

This is where electronic evidence comes into play—the unsung hero of digital transformation.

What is electronic evidence?

Electronic evidence is a set of structured data (metadata, network logs, signatures, and timestamps) that allows a digital event to be reconstructed with absolute certainty.

What is truly important is being able to reliably verify aspects such as:

• Authenticity: who performed the action.
• Integrity: whether the information has remained intact since the operation was performed and on exactly what content the action was performed.
• Non-repudiation: The impossibility of one of the parties saying, “It wasn’t me.”

The Importance of Traceability

Every digital interaction leaves a technical trail that, when properly managed and preserved, provides confidence and serves as evidentiary support.

Traceability thus becomes an essential element when it can be demonstrated:

• what was sent,
• what was received,
• that the content has not been altered,
• and that the identity of the parties involved can be verified.

Electronic signatures and evidence: two inseparable concepts

The electronic signature is one of the clearest examples of the importance of electronic evidence.

Signing a document digitally is not merely a matter of adding a signature or clicking an acceptance button. Behind this process lie various technological mechanisms that ensure:

• the identity of the signer,
• the integrity of the document,
• the date and time of the transaction,
• and the impossibility of modifying the content without leaving a trace.

The evidence associated with the signature is what provides true legal and evidentiary value to the transaction. However, it is important to note that the evidentiary value will vary depending on the type of signature used.

Certified Electronic Notifications

Another area where electronic evidence is essential is that of electronic notifications.

When a company needs to communicate important information—such as contractual notices, claims, renewals, or legal communications—it must not only send the message but also be able to prove that the message was successfully delivered.

Electronic evidence allows for the verification of essential aspects such as:

• the exact content communicated,
• the date and time of sending,
• delivery to the recipient,
• access to or reading of the notification,
• and the integrity of the entire communication.

This makes certified electronic notifications a particularly useful tool for providing legal certainty and reducing risks.

Conclusion: Security Equals Profitability

Digitizing processes isn’t just about eliminating paper. It’s about creating an environment where every transaction leaves a solid, legally binding trail. Investing in high-quality electronic evidence isn’t an expense; it’s your company’s best defense.

Professional bodies are required to use electronic notifications in their administrative procedures in various situations, as set out in Law 39/2015 of 1 October on the Common Administrative Procedure of Public Administrations.

In this context, many professional bodies are asking themselves: is it mandatory to notify members electronically?

The answer is clear: yes, in most cases. .

Who is required to do so?

Under Article 14.2, the following must communicate with the Administration electronically:

• Legal entities
• Entities without legal personality
• Professionals subject to compulsory registration with a professional body (solicitors, architects, engineers, etc.)

How does this affect professional bodies?

Very directly.

Professional bodies must notify their members electronically of all administrative procedures that concern them, particularly those involving sanctions or decisions affecting members’ rights.

Ensuring that the referee receives them correctly.

How does this work in practice?

In its day-to-day operations, a professional association must use electronic means to:

• Submit decisions
• Communicate agreements and notices
• Notify disciplinary sanctions
• Handle any administrative procedures

All of this ensures that the member actually receives the communication.

The solution: digitising your notifications properly

This is where specific tools such as the following come into play:

Xolido Notify

Benefits of Electronic Notification

The shift from paper to electronic filing is not merely a bureaucratic burden; it offers tangible benefits for both parties:

• Efficiency and Speed: A significant reduction in delivery and receipt times.
• Legal certainty: There is an accurate record of the date and time when the content was made available and accessed (or when the notification was rejected).
• Sustainability: A reduction in paper usage and postal delivery costs.

In summary

It’s not just about sending emails.

It’s about ensuring your communications comply with legal requirements and managing your relationship with your members effectively.

Administrative management in schools, colleges and training centres involves dozens of documents each academic year that must be signed, sent and filed correctly.

Assessment reports, enrolments, qualifications, work experience agreements, employment contracts and communications to families are all part of the day-to-day running of any educational centre.

When these processes are managed on paper or through in-person signatures, the result is often the same: delays, a backlog of tasks and a heavy administrative burden, especially at the end of the academic year.

The good news is that there are now electronic signature solutions for educational centres that simplify all these processes.

The most time-consuming administrative procedures in an educational centre

In most educational centres, the secretarial and management team spends many hours managing documents that require a signature or certified delivery.

Among the most common are:

• Assessment reports
• Enrolment processes
• Issuing of qualifications and certificates
• Internship agreements with companies
• Staff employment contracts
• Certified communications to parents and guardians
• Schedule changes and urgent notices
• Various authorisations: Authorisation for image recording, for local outings, etc.

When these procedures depend on the physical presence of the signatories, the process slows down and can cause unnecessary delays.

Electronic signatures in educational institutions: an increasingly necessary solution

The digitisation of academic management allows many of these administrative processes to be automated.

With an electronic signature solution, educational institutions can:

• Sign official documents digitally and with legal validity.
• Collect multiple signatures from teaching staff through a signature circuit.
• Manage assessment records without the need for face-to-face meetings
• Send certified electronic communications to families
• Maintain traceability and legal certainty for all processes carried out
• Reduce paper usage and physical filing

This not only improves administrative efficiency but also makes the work of teaching and management staff easier.

Get ready for the end of the academic year

One of the busiest times of the year for any educational institution is the end of the academic year.

In just a few weeks, you have to deal with:

• Final assessments
• Signing reports
• Processing qualifications
• Preparing for the next academic year
• Enrolment and academic documentation

Digitising processes before this period arrives allows you to avoid bottlenecks and work more calmly when the workload increases.

XolidoSign Professional: Electronic signatures and certified electronic communications to simplify academic management

Tools such as XolidoSign Professional enable educational institutions to digitise their document processes easily and securely.

With XolidoSign Professional, it is possible to:

• Sign assessment reports electronically
• Manage signature flows between teachers and management
• Formalise internship agreements
• Sign employment contracts
• Send legally valid certified communications to families

In this way, the educational institution gains administrative efficiency, reduces management time and improves internal organisation

Digital transformation also begins in the school office

Digitisation in education is often associated with classrooms, but administrative management can also benefit greatly from digital tools.

Simplifying document signing and communication processes allows management and administrative teams to devote more time to what really matters: academic organisation and student support.

Preparing in advance is the best way to avoid administrative stress at the end of the academic year.

Implementing electronic signatures in educational institutions is one of the simplest and most effective steps towards advancing this transformation.
