The change that affects every claim
Don't let your claim be rejected over the ADR requirement
Since Spain's Organic Law 1/2025, attempting an ADR is a procedural requirement for most civil and commercial claims. Courts accept electronic means with guarantees of sending, receipt, date and identity: exactly what a notification certified by a trusted third party provides.
- Prove the attempt with proof of receipt, date and IP.
- Without revealing the content of the offer (confidentiality, art. 9).
- The receipt accompanies the claim and reinforces the pro actione principle.
What is provenThat the offer was sent and received by the other party, with a certain date.
Time runs in your favourIf 30 days pass with no reply, the attempt is deemed to have taken place.
What is NOT revealedThe content of the negotiation, which is confidential.

Frequently asked questions
Legal sector questions
Is a Safe Stamper notification enough to prove an ADR attempt?
Provincial courts have been accepting electronic means with guarantees of sending, receipt, date and identity. A notification certified by a trusted third party, with proof of receipt and a timestamp, fits that criterion. The final assessment rests, in each case, with the court.
Do I have to reveal the content of the offer to prove the attempt?
No. For the procedural requirement it is enough to prove sending and receipt; the content of the negotiation is confidential (art. 9 of Organic Law 1/2025) and is submitted separately only if the court requires it.
What type of electronic signature do you offer?
Advanced electronic signature in line with eIDAS, sufficient for most contracts, engagement letters and NDAs. It is not a qualified signature, which is only required for specific procedures.
Can I manage my clients' IP?
Yes, with the Enterprise plan: delegated registration, becoming their technology provider.
Is the evidence valid outside Spain?
It is generated with qualified timestamping under the European eIDAS regulation and a blockchain audit. For users in Mexico it also includes the NOM-151 record.
What evidentiary value do they have?
They are technological evidence with probative capacity; their assessment rests, like any evidence, with the body that analyses it. They do not constitute legal advice.
