Client Portals for UK Law Firms: What to Build, What to Avoid

Ask anyone working in a small law firm what eats their week and you will hear the same answer: chasing documents and answering "any update on my case?" emails. A well-built client portal fixes much of that. A badly built one becomes another password clients forget.

I have built websites and practice systems for UK legal clients, including Stonebridge Legal Solutions. These are the lessons that matter.

What a portal should do first

Start with the jobs that create the most back-and-forth:

• Secure document upload. ID, proof of address and case documents go straight to the matter, not into someone's inbox.
• Case status at a glance. A simple timeline showing where the matter is and what happens next.
• Messages tied to the matter. One thread per case, stored with the file, instead of scattered emails.
• Tasks for the client. "Sign this", "upload that", with reminders, so nothing waits on a forgotten email.
• Appointments. Booking and rescheduling without phone tag.

Everything else (payments, e-signatures, fee estimates) can follow once clients are using the basics.

Compliance to plan for from day one

This is not legal advice, and your compliance officer should review any system before launch. But these are the areas I design around from the first conversation.

UK GDPR and confidentiality

Client data is personal data, often special category data. That means:

• Access limited by role and by matter, so staff see only what they work on
• Encryption in transit and at rest
• Files stored privately and served only after a permission check, never by public link
• A clear retention policy, with records deleted or archived on schedule
• A full audit log of who viewed or changed what

Identity checks and onboarding

Many matters require client identification and anti-money laundering checks. A portal can collect documents and integrate with an identity verification provider, but the firm stays responsible for the decision. Build the workflow so a person signs off each check.

Your public website

The SRA expects certain information on firm websites, such as the SRA digital badge and, for some services, price and service information under the Transparency Rules. A portal project is a good moment to check the public site meets these too.

Mistakes that sink adoption

• Too many features at launch. Clients use what is simple. Launch small and add.
• Forcing app downloads. A mobile-friendly web portal works for far more clients than a native app.
• Weak login recovery. If resetting a password needs a phone call, people will email instead.
• Staff not using it. If fee earners still reply by email, clients will too. Make the portal the easiest path for staff as well.

Measure success by fewer status-update emails and faster onboarding, not by the number of features.

Build or buy?

Many case management systems include a portal, and if you already use one, switch it on first. A custom portal makes sense when your process doesn't fit those tools, when you need it to connect several systems, or when the portal is part of how you win clients, such as a fixed-fee online service.

A sensible first phase

1. Secure login with two-factor authentication
2. Document upload linked to the matter
3. Case timeline and messages
4. Client tasks with email reminders
5. Admin screens for staff, with audit logs

That is usually enough to cut chasing noticeably within weeks. If your firm is weighing up a portal, let's talk it through.
