File sharing for law firms, built around the matter.
Secure file sharing for solicitors and legal teams should make sensitive exchanges easier to govern. Collect client records, exchange evidence and release legal documents through a controlled route that keeps each file tied to the right matter, participant and decision.
A case file should not become an email trail.
Attachments are easy to send, but difficult to govern once they are copied, renamed and forwarded. Unlike general cloud storage for law firms, My MX Data is focused on controlled, auditable handoffs. It gives legal teams a defined route for sharing sensitive files with clients, reviewing responses and approving final release.
The client receives a defined request for identity and source documents inside the relevant matter.
The returned file stays linked to the request instead of arriving as an unrelated attachment.
The assigned solicitor reviews the current version and records the next action for the matter.
Only the selected pack becomes available to counsel under the access conditions set for that role.
Give every participant the access their role requires.
A client, barrister, expert and counterparty do not need the same view. Select a participant to see how matter content can remain separated inside one controlled exchange, with encrypted file sharing and permissions applied around the intended purpose.
The complete working record stays with the authorised matter team.
Solicitors and approved internal colleagues can review client material, legal analysis, instructions, disclosure decisions and activity evidence according to their responsibility for the matter.
Use one controlled environment across varied practice areas.
Law firm document collaboration changes from one practice area to another, but the core need remains the same: collect the right records, limit the audience, keep the current version clear and retain evidence of important actions. My MX Data supports controlled file collaboration without becoming a live co-authoring platform.
Keep property records moving without losing sight of the transaction.
Request identity documents, title material, searches, finance evidence and signed forms through one route that keeps every response connected to the property matter.
Control who sees evidence, instructions and working analysis.
Build a defined evidence set for clients, counsel and experts while internal legal analysis and unrelated material remain inside the authorised team view.
Keep due diligence requests, replies and approvals tied to the deal.
Organise commercial documents across buyers, sellers, advisers and specialists without giving every participant broad access to the full transaction record.
Handle personal records with care and a clear reason for access.
Collect estate, trust, probate and family records through a private route that clients can understand without exposing sensitive information through long email chains.
Separate confidential instructions from documents prepared for exchange.
Collect contracts, correspondence, investigation records and settlement documents while keeping internal analysis and approved disclosure sets clearly apart.
Answer later questions without rebuilding the file history.
When a legal exchange needs to be checked, the useful questions are practical: who requested the document, who supplied it, which version was reviewed, who approved release and when external access ended. That traceability can support GDPR-aligned file sharing processes and a more defensible matter record.
The request defined the matter, intended recipient and records required before the client supplied information.
The upload remained connected to the original request and the correct matter instead of entering a general mailbox.
The review record showed which file was checked and who remained responsible for the next action.
The external participant received the approved evidence set without access to internal notes or unrelated client records.
The matter record retained useful evidence even after the participant no longer required access.
Built for confidential work that crosses firm boundaries.
My MX Data gives law firms a practical route for collecting, reviewing and releasing sensitive documents through a secure upload portal. It complements legal file storage solutions by governing the exchange itself rather than acting as a permanent document repository.
Protected legal document exchange beyond an ordinary shared link
Use named access, AES-256 protection and My MX Data's quantum secure patented methodology when confidential documents move between clients, solicitors, counsel, experts and other approved participants. The ASR process anonymises, shards and restores files for authorised users.
Structured client document collection
Request identity records, evidence, signed forms and supporting files through a defined upload route connected to the correct matter.
Clear version handling
Keep revised drafts and approved records connected to the matter so users do not need to judge the current file from its name.
Role based external access
Give a client, barrister, expert or counterparty access to selected content without opening the full matter record.
Reviewable activity
Retain useful evidence around requests, uploads, access, review, approval and closure when the matter needs later scrutiny.
Technology should support professional judgement, not replace it.
UK law firms need to protect confidential client information and apply appropriate security to personal data. My MX Data provides practical controls that can support those responsibilities, strengthen information governance and help the firm evidence how sensitive legal file transfers were handled.
Use named participants and scoped matter access to reduce unnecessary visibility of current and former client information.
Control supportApply protected handling and access conditions when personal data is collected, reviewed or released to an external participant.
Security supportProvide each participant with the material relevant to their role rather than the entire matter file by default.
Access supportRetain useful activity evidence that can help the firm show how important exchanges and decisions were handled.
Evidence supportReview or end external availability when counsel, experts, clients or counterparties no longer require access for the stated purpose.
Lifecycle supportSecure file sharing without making client work harder.
My MX Data gives solicitors a controlled alternative to loose attachments while keeping the route clear for clients and external professionals.
Law firms can use My MX Data to exchange most files connected with a client matter, provided the firm has a lawful purpose and applies its own professional and information governance controls. Typical examples include client identity records, contracts, evidence, witness material, transaction documents, title records, expert reports, signed forms, disclosure packs and completion documents.
The platform is particularly useful where an attachment or open link would leave the firm with too little control or evidence. Teams can create a defined request, collect documents through a secure upload route, assign access to named participants and retain a clearer record of the exchange.
- Client onboarding and source documentation
- Litigation evidence and counsel bundles
- Due diligence and transaction packs
- Large media, scans or data sets that need secure large file transfer
The NCSC legal sector threat report gives wider guidance on the cyber risks faced by UK legal practices. My MX Data supports the secure exchange process, while the firm remains responsible for matter classification, retention, supervision and appropriate use across each matter.
Yes. Access can be shaped around the participant's role and the purpose of the exchange. A client may need to see document requests and records released for review, while counsel may only require an approved evidence pack. An expert might receive selected instructions and supporting material, with a route to return a report.
This role-based approach helps a firm avoid exposing the full matter file merely because one external participant needs a small part of it. It also supports a clearer client file sharing process without relying on public links that can be forwarded beyond the intended audience.
- Named-user access rather than anonymous link access
- Permissions aligned with the participant's task
- Expiry or review conditions for time-limited involvement
- Activity evidence that helps the team see what happened
The ICO explains that data protection by default includes limiting personal information to what is necessary for each purpose. Its data protection by design guidance is useful context. My MX Data provides supporting controls, while the firm decides what each person should see.
My MX Data can support the way a firm separates and controls privileged or confidential material, but software does not determine whether privilege exists. That assessment depends on the document, the purpose for which it was created, the parties involved and the applicable law.
Operationally, the platform can help legal teams keep internal analysis, client documents, evidence sets and approved releases within different access scopes. Using encrypted legal file sharing, named participants and matter-specific permissions can reduce casual or unnecessary exposure when documents move outside the core team.
- Keep internal working analysis away from external views
- Release only the documents approved for counsel, experts or counterparties
- Record key access and release actions for later review
- Use controlled collaboration instead of fragmented email threads
The SRA's confidentiality of client information guidance states the professional duty to keep current and former clients' affairs confidential, subject to limited exceptions. Firms should combine platform controls with legal judgement, documented policies, staff training and appropriate supervision throughout the matter lifecycle, including partner review and closure decisions.
My MX Data can retain detailed activity evidence around sensitive file exchanges. Depending on the workflow and configuration, a firm can see events such as a request being created, a named user uploading or accessing a file, a document being reviewed, a release being approved and external availability being closed.
This is useful because the value of an audit trail is not simply technical. It helps the firm answer practical questions later without reconstructing the matter from inboxes, local folders and recollection. It can also support stronger governance around GDPR file sharing by giving compliance and legal teams a clearer record of the controls applied.
- Who requested or supplied a document
- Which participant accessed the file
- When review or release actions occurred
- When access was changed or withdrawn
The ICO's accountability guidance explains that organisations must be able to demonstrate how they meet UK GDPR requirements. My MX Data can provide useful technical evidence and clearer operational context, but it does not replace the firm's policies, records of processing or professional decisions.
Yes. External availability can be reviewed or ended when the participant no longer needs the files for the stated purpose. This is helpful for counsel after a hearing, an expert after delivering a report, a client after completing a specific review, or a counterparty once an approved document exchange has finished.
Time-limited access reduces the chance that sensitive material remains available indefinitely merely because nobody returned to close an old link or folder. My MX Data is designed for controlled secure file delivery, not permanent cloud storage for law firms. The firm can therefore treat the exchange as a governed handoff while retaining the activity evidence it needs.
- Set a defined review or expiry point
- Remove access when the role or purpose ends
- Keep an internal record of the action taken
- Transfer final records into the firm's approved DMS or retention process where required
The ICO's data protection principles guidance covers storage limitation and data minimisation. The appropriate closure, transfer and retention decision remains the responsibility of the law firm.
No. No file sharing platform can guarantee that a law firm is compliant by itself. Compliance depends on the firm's legal basis, policies, people, supervision, retention decisions, client duties and how the technology is configured and used.
My MX Data can help facilitate compliance efforts by providing controls that support a more accountable exchange process. These include named-user access, AES-256 protection, the quantum secure patented methodology known as ASR, permissions, expiry settings and detailed activity evidence. Together, they can support the firm's wider UK data protection processes and ISO 27001-aligned controls.
- Reduce reliance on open links and uncontrolled attachments
- Apply access around an identified recipient and purpose
- Retain evidence that can support audits and internal review
- Close access when the exchange no longer requires it
The SRA Standards and Regulations and the ICO's security guidance remain the relevant starting points for professional and data protection duties. My MX Data supports those objectives and helps create a more defensible exchange process; it does not replace legal advice, risk assessment or compliance management.
