For UK law firms
ID and AML checks
your file can defend.
Your client verifies from their phone in minutes. You get an audit-ready record — with your MLRO's decision on anything that flags.
Currently a private pilot with a small number of firms.

The problem
Onboarding shouldn't cost you a morning
Most firms still do client due diligence with a photocopier and good intentions.
Certified copies and chasing
Clients post documents in, or email photographs to a fee earner who has to file them somewhere sensible.
The evidence is scattered
A screenshot here, an email there. When the SRA asks what you did and why, it is reassembled from memory.
Hits get waved through
A sanctions or PEP match needs a judgement call. Too often that call is made verbally and never written down.
How it works
Three steps, start to filed
The fee earner does about thirty seconds of work.
Send a link
Enter the client’s name and your matter reference. A secure, expiring link goes out.
They verify on their phone
Document, a live selfie and proof of address. No app to download, no account to create.
You get the record
Identity and screening results, and a PDF for the matter file. Anything flagged goes to your MLRO first.
What you are buying
The check is a commodity. The decision is not.
Plenty of companies will screen a name against a list. A file review turns on whether a named officer looked at the match, decided what to do, and wrote down why.
- Flagged matters cannot quietly proceed — they land in the firm’s review queue.
- The MLRO records cleared, escalated or declined, with written reasoning.
- The decision is single-shot. It cannot be rewritten after the fact.

Trust & data handling
What we can actually show you
Six controls that are built and tested. Put them in front of your COLP.
Firms are isolated
A request for another firm’s record returns “not found”, so its existence is never confirmed.
Client links expire
Every verification link is single-use and time-limited, and is never served from a public path.
Documents need a session
An identity document can only be retrieved by a signed-in member of the firm that raised the matter.
MLRO review is enforced
A flagged matter cannot proceed without a recorded decision, and that decision cannot be altered afterwards.
Tamper-evident history
Each audit entry carries a hash of the one before it, so altered or missing history is detectable.
Retention you configure
Your firm sets how long documents are kept. We apply no default and delete nothing on our own initiative.
What you will not find here: certifications we do not hold, or a promise that this history is impossible to alter. It is tamper-evident, which is a weaker and more honest claim — we set out exactly where the line falls.
The product
What's included
Document and biometric check
Passport or driving licence, matched against a live selfie.
Sanctions, PEP and adverse media
Screened at onboarding, recorded against the matter.
Proof of address
Uploaded by the client, stored with the case.
Firm-wide visibility
Every matter in one list, so there is cover during holidays.
MLRO review queue
A compliance view of everything flagged and everything decided.
Audit-ready PDF
A report per client, ready for the matter file.
Access
A private pilot, by invitation
MatterProof is being built with a small number of UK firms. Accounts are issued directly to those firms — there is no public sign-up, and no pricing is published while the commercial terms are still being settled.
We would rather say that plainly than take enquiries we are not yet ready to answer.

Straight answer
Where we are, honestly
MatterProof supports your firm's customer due diligence. It does not carry out your risk assessment and does not take on your obligations under the Money Laundering Regulations. The decisions and the responsibility stay with the firm.
We are new, and we are not going to show you a wall of logos we haven't earned. If your COLP has questions about how data is handled, put us in front of them.
FAQ
Questions
- Does my client need to download anything?
- No. They tap the link and it opens in the browser already on their phone. No app, no account.
- What happens when a client comes back flagged?
- The matter cannot proceed on its own. It enters your review queue, and an MLRO must record cleared, escalated or declined with written reasoning. That goes onto the report and into the audit history.
- Where are the documents stored?
- In private storage that is never publicly reachable. Only a signed-in member of the firm that raised the matter can retrieve them; anyone else gets “not found”.
- Can more than one person at the firm use it?
- Yes — fee earner and MLRO roles, with matters visible firm-wide for holiday and illness cover. The compliance queue is restricted to MLROs.
- How do we get an account?
- Accounts are issued directly to firms in the pilot. There is no public sign-up.
