For Law Firms

You can prove
you sent it.
Can you prove
who collected it?

Secure portals and web forms confirm that an upload completed. They cannot tell you that a named, identity-checked person took possession — because nothing in the chain ever checked who was on the other end. ProntoDeliver does, and it issues the receipt to both sides.

The Gap

“Submitted” is not
“received”

Every file transfer passes through four distinct states. The tools most firms use are genuinely good at the first three. The fourth — the one your file note quietly assumes — is the one nothing produces, because producing it requires checking a person rather than a session.

01
Sent
The file left your firm.
Email, portal, courier — everything evidences this.
Covered
02
Delivered
The file reached the other side’s system.
A server accepted the bytes. A mailbox, a storage zone, a queue.
Covered
03
Accessed
A link was opened or an account signed in.
Evidence about a session, not a person. Credentials get shared, forwarded and inherited.
Covered
Conventional tools stop here
04
Collected
A named person, checked against a government document and a live face, took possession.
This is the state your file note assumes. Almost nothing produces it.
The gap
An audit log tells you a credential was used. It does not tell you whose hands were on the keyboard — and in a contested matter, that is the only question anyone asks.

This is not a criticism of any particular product. Secure email, managed file transfer and web submission forms all solve the problem they were built for, which is confidentiality in transit and at rest. Identity was simply never in scope. An email address is a routing instruction, a portal account is a credential, and neither is a person. Where the stakes are a limitation date, a disclosure obligation or a privileged document reaching the wrong household, the firm is left evidencing delivery with material that was never designed to evidence it.

In Practice

Where the gap
costs you

The absence of a receipt is invisible until the moment someone disputes it. Then it is the whole file.

Deadlines and limitation

A dispute about when something was received is a dispute about the date, and the date decides the point. A submission confirmation timestamps your upload. It says nothing about when the other side actually came into possession.

Chain of custody on intake

Documents arriving through an open web form carry an asserted name and an email address. If provenance is later challenged, the firm is reconstructing it from headers and recollection rather than producing a verified identity captured at the moment of upload.

Confidential material to shared inboxes

Family, employment and private client work routinely sends privileged material to addresses another person can reach. A delivery method that checks the reader, not the mailbox, is a control rather than a hope.

Subject access and data requests

Article 12(6) UK GDPR lets a controller ask for further information where there is reasonable doubt about a requester’s identity. Releasing a subject access bundle to an impersonator is itself a breach. Verifying at the point of collection puts the check where the disclosure happens.

Undertakings and completion

Conveyancing and transactional work runs on documents moving between parties to a timetable. Where an undertaking turns on delivery, the firm carries the risk of proving it — and payment redirection fraud lives in exactly this gap.

Client care and complaints

“I never received it” is one of the most common complaints a firm has to answer and one of the hardest to rebut. A collection receipt turns a credibility contest into a document.

Both Directions

Files out.
Files in.

Most secure transfer tools are strong in one direction and an afterthought in the other. Identity is the same primitive whichever way the file is moving, so ProntoDeliver treats both the same way.

firm → client

Sending a document out

Bind the file to the named recipient. The claim link reveals only the filename, size and what verification is required — never the contents. When the recipient passes the check, the file decrypts and the fee earner gets a receipt naming the person who collected it. Forward the link to a spouse, a colleague or an opponent and it will not open, because the check is on the face, not the inbox.

  • Name checked against the document MRZ
  • Live biometric check at the point of collection
  • Receipt to the fee earner on collection
  • Single-use or capped download policy
  • Revocable at any point before collection
client → firm

Receiving a document in

Publish an intake link the way you would publish a submission form, with one difference: the sender verifies who they are before the upload is accepted. The firm receives a verified name bound to the file and its hash at the moment of intake. And the sender is not left guessing — when someone at the firm collects the file, an acknowledgement goes back to them.

  • Verified sender identity captured at upload
  • File hashed on arrival for later comparison
  • Acknowledgement back to the sender on collection
  • Works for clients, counterparties and third parties
  • No account for the sender to create

The reciprocal acknowledgement is the part firms tend to underestimate. A client who uploads medical records or bank statements into a one-way form and hears nothing will phone the office to ask whether it arrived, and someone will spend ten minutes finding out. Closing that loop is a receipt for them and an hour a week back for you.

The Artefact

What ends up
on the file

A receipt is only useful if it is still useful in two years, in front of someone who is inclined to doubt it. Each ProntoDeliver receipt is a self-contained record of what was checked and when, hashed and sealed so that alteration is detectable rather than merely discouraged.

File
Name, byte length and SHA-256 digest of the exact file released
Person
Legal name as read from the document, with the MRZ treated as authoritative
Document
Type, issuing state and expiry of the credential presented
Liveness
Result of the biometric check performed at collection, not at signup
Time
UTC timestamp of the collection event
Session
IP address and user agent recorded against the claim
Seal
SHA-256 attestation hash, sealed with an AWS KMS key

Failed and abandoned attempts are recorded too, with the reason. A record that only ever shows success is not an audit trail.

Why it holds up
Checked at collection, not at signup
The biometric check happens at the moment the file is released. A receipt that relies on an identity verified six months ago at account creation is evidence about an account, not about the collection.
The MRZ is treated as authoritative
Names are read from the machine-readable zone of the document rather than from anything the user typed. Nothing supplied by the recipient is trusted as an identity claim.
The file itself is hashed
The receipt names the exact bytes released. If a dispute later turns on which version was delivered, the digest settles it.
The seal is independent of the file
Ciphertext is deleted on expiry. The receipt and the audit record survive it, because the evidence of delivery should outlive the delivery.

Due Diligence

You are verifying
them anyway

Firms in scope of the money laundering regulations already have to identify the client from a reliable, independent source before the relationship gets going. That work happens today in a separate system, on a separate day, producing a separate record that lives somewhere other than the matter file.

ProntoDeliver runs on the same verification engine. The check that satisfies your onboarding evidence is the check that produces the delivery receipt, and it is captured against the matter rather than filed away in an onboarding tool. One interaction with the client, two obligations evidenced — and a client who is asked for a passport once rather than twice.

Where the responsibility sits

The regulations permit electronic identification where the process is secure from fraud and misuse and provides the necessary degree of assurance. Sector guidance is equally clear that the firm must satisfy itself that a given technology meets the assurance level its risk assessment demands. We give you the evidence and the audit trail. The compliance decision stays with your MLRO, as it should.

1
Onboarding
Client verifies once. Document, MRZ and live biometric captured against the matter reference.
2
Evidence
The verification record is retained in a form you can produce on a file audit or supervisory visit.
3
Delivery
Every subsequent document exchange on that matter reuses the same identity anchor.
4
Receipt
Each exchange adds a dated, sealed collection record to the file without anyone chasing it.

The EU anti-money laundering regulation applicable from 2027 extends and tightens these duties across member states. Firms choosing verification infrastructure now are choosing what they will be audited on then.

Straight Answers

What this
is not

You will read the small print, so here it is in large print. These are the limits we would want disclosed to us.

Not a qualified registered delivery service
ProntoDeliver is not a qualified electronic registered delivery service under Article 44 eIDAS, so it does not carry the Article 43(2) presumption. Article 43(1) means the evidence is not excluded simply for being unqualified. Qualified sealing through a QTSP is on our roadmap; we will not describe it as present before it is.
Not service of process
Nothing here satisfies CPR Part 6, FRCP Rule 5, or any national equivalent for service. Where a rule prescribes a method of service, follow the rule. ProntoDeliver is evidence of receipt, not a mode of service.
Not a compliance determination
We supply verification evidence. Whether it meets the assurance level your risk assessment requires is your decision as the regulated firm, and your supervisor will treat it that way.
Not a recall mechanism
Once a verified recipient has collected the file, the bytes are on their device. Watermarking deters onward sharing; it does not prevent it. Anyone claiming otherwise is selling you something that does not exist.

What is left after all of that is still the thing you cannot get anywhere else: a contemporaneous, sealed record that a specific human being, checked against a government document and a live face, took possession of a specific file at a specific moment.

Getting Started

Start with
one workflow

Nobody should replace their file transfer estate on a first conversation. Pick the workflow where a missing receipt would hurt most and run that one.

1

Pick the painful one

Usually it is client onboarding documents, a disclosure exchange, or the subject access responses nobody wants to send by email.

2

Run it in parallel

Keep your existing route in place. Send through both for a fortnight and compare what each one can actually prove afterwards.

3

Show your MLRO

Bring the audit trail to whoever signs off on risk. That conversation decides adoption far more reliably than a demo does.

FAQ

The questions
you will ask

Written for the person in the firm whose job is to find the hole in it. Anything missing? Ask us directly.

No. ProntoDeliver is not currently a qualified electronic registered delivery service under Article 44 of Regulation (EU) 910/2014, so it does not carry the Article 43(2) presumption that attaches to qualified services. Article 43(1) provides that data sent using a non-qualified electronic registered delivery service is not denied legal effect or admissibility as evidence solely because the service is not qualified. What ProntoDeliver adds is the strength of the identity check itself: qualified services generally identify the addressee through an account or credential, whereas ProntoDeliver checks a government-issued document and a live biometric at the moment of collection.
Admissibility and evidential weight are matters for the tribunal and the applicable procedural rules, and we make no guarantee about either. A ProntoDeliver receipt is a contemporaneous, tamper-evident record of what was checked, when, and by whom, sealed with an AWS KMS key and carrying a SHA-256 hash of both the file and the attestation. It is intended to be better evidence than a server log, not a substitute for legal advice on how to deploy it.
No — the CDD decision remains the firm's. Regulation 28(19) of the Money Laundering Regulations 2017 permits electronic identification processes as a reliable and independent source where the process is secure from fraud and misuse and gives the necessary degree of assurance. The LSAG guidance is clear that firms must satisfy themselves that any technology provides an appropriate level of assurance for the risk. ProntoDeliver supplies the underlying verification evidence and retains it in a form you can produce on a file audit; it does not make the compliance determination for you.
Not every client can or should be pushed through a device-based check — capacity, disability, digital exclusion and safeguarding all cut against a single mandatory route. Deliveries can be configured so that a failed or declined check routes the matter back to the firm rather than blocking the client, with the exception recorded on the audit trail so the fee earner can apply the firm's existing process. Firms subject to the Equality Act 2010 should treat the alternative route as a reasonable adjustment, not an edge case.
The firm remains controller for the contents of the file and for the underlying matter. ProntoID acts as an independent controller for the identity verification data it collects from the individual, because it determines how that data is verified, retained and re-used across the platform, and it contracts directly with the individual for that purpose. This is a different arrangement from a straightforward processor model and should be reflected in your privacy notice and record of processing.
Yes. The firm publishes a claim link and the sender verifies their identity before the upload is accepted, which gives you a verified name bound to the file and its hash at the point of intake. This is the same primitive used in reverse for outbound delivery, and it is the direct answer to one-way submission forms that tell you a file arrived but not who sent it.
Ciphertext is deleted at the expiry time you set, via S3 lifecycle rules, so the file ceases to exist rather than merely becoming unreachable. The receipt and audit record persist independently of the file, which is the point: the evidence of delivery should outlive the delivery. Files already collected cannot be recalled — once the bytes are on the recipient device they are beyond anyone's reach.
ProntoDeliver is API-first, so deliveries can be created from whatever system already holds the file. Integration depth with specific practice management and DMS platforms varies — tell us what you run and we will be candid about what is available today versus what would need building.
