Ley 2213 de 2022, art. 8
Serve in minutes. Prove delivery for ten years.
Electronic notification with proof of delivery: the message is frozen and timestamped before it leaves, and every event joins a chain any expert witness can verify without taking our word for it.
From COP 800 + VAT per recipient
Free for 90 days once your tarjeta profesional (bar card) is verified. No credit card.
- ≥ 2 stamps
- RFC 3161 timestamps from independent authorities on every fingerprint.
- SHA-256
- chained: alter one event and every event after it breaks.
- 10 years
- in write-once storage that not even we can delete.
- OpenSSL
- is all it takes to verify the evidence package, with no access to Notificado.
The problem
Physical mail is slow, expensive, and leaves the proof for later
And an email sent without evidence leaves the question open exactly where it matters most.
Over COP 15,000
for each notification sent by physical postal mail.
Days to weeks
before the delivery receipt reaches your office and you can inform the court.
“It never arrived”
is how a motion to annul (nulidad) begins. What decides it is the evidence of delivery you can put forward.
How it works
From auto admisorio to proof of delivery, in four steps
Built around the litigator's work: radicado, juzgado, sworn statement and memorial.
Register the case
The 23-digit radicado (court case number), the juzgado and the parties. Everything stays tied to the case.
Upload the order and annexes
Each file gets its SHA-256 fingerprint on upload, and you see it before sending.
Declare where the address came from
Under oath and with your supporting evidence, as art. 8, paragraph 2 requires.
Send and get the constancia
The message is frozen and stamped before it leaves, events are logged in Colombian legal time, and you get a signed PDF constancia and the memorial for the court.
The evidence chain
Every event carries the fingerprint of the one before
If anyone alters an event, its fingerprint stops matching from that point on and verification names the event. The hashes in this example are real: alter a block and see where the chain breaks.

Illustrative example; it belongs to no real notification. Times in Colombian legal time.
Read the evidence methodFor the court
What the judge receives
A PDF constancia that verifies in seconds, and an evidence package that verifies without us.
Signed constancia (PAdES)
The PDF carries our digital signature: any later change invalidates it.
A fingerprint for every document
SHA-256 of the exact message and of each annex, to show what was sent.
Events in legal time
Acceptance by the recipient's server, downloads and acknowledgement of receipt, in Colombian time and UTC. An open is listed as an indicio (circumstantial evidence), never as proof of reading.
Two timestamps
RFC 3161 tokens from two independent authorities, kept exactly as issued.
Verification QR code
It opens the verification page, where the judge or the opposing party checks the constancia without an account.
Evidence package
The original .eml, the timestamps, the mail provider's raw responses and a verifier that runs offline.

What lawyers usually ask
Is personal notification by email valid?
Art. 8 of Ley 2213 de 2022 allows personal notification by sending the court order as a data message to the electronic address provided by the interested party, with the sworn statement about where it came from. The validity of each notification is for the judge of the case to decide.
What if the defendant says they never got the email?
We keep the response of the recipient's mail server when it accepted the message, with its IP address and time, plus downloads and the acknowledgement of receipt if any. Everything sits in an event chain that cannot be altered unnoticed, and in a package an expert can verify without our system.
Does knowing they opened the email prove they read it?
No. Some mail services open images automatically. That is why we always show an open as an indicio, never as proof of reading. The proof is server delivery, downloads and the acknowledgement of receipt.
