For most small and mid-size law firms, a well-built WordPress site is the practical choice: you can edit it, many developers know it, and you own it. A custom-built site makes sense when you need top speed, unusual features or less maintenance surface, and you accept that changes go through a developer.
Either can rank and convert. Either can also fail. The platform matters less than how the site is built, who maintains it, and whether your firm owns it.

Key Takeaways
- WordPress is open source under the GPL, so you can run, change and move it without asking a vendor's permission.
- WordPress security depends on upkeep: its own hardening guide stresses updates, removing unused plugins, backups and two-step login.
- Custom sites can be fast and lean, but you depend on developers who know the code base.
- Google's Core Web Vitals give clear speed targets that any platform can meet or miss.
- Ownership and maintenance terms matter more than the platform choice.
What "WordPress" and "custom" mean here
WordPress here means a self-hosted WordPress site with a theme and plugins. WordPress.org describes it as open source software licensed under GPLv2 or later, with four freedoms: to run it, study and change it, redistribute it, and distribute modified copies.
Custom-built means a site coded for your firm, often with a modern framework and a separate content system. It can also mean a hand-coded static site. Proprietary website builders sold by legal marketing vendors are a third option, covered below.
Side-by-side comparison
| Factor | WordPress | Custom-built |
|---|---|---|
| Ownership | Open source; you can move it to any host | You should own the code; check the contract |
| Editing | Familiar editor; staff can update pages | Depends on the content system chosen |
| Developer pool | Large | Smaller; tied to the stack |
| Security work | Ongoing updates to core, theme, plugins | Smaller attack surface; still needs updates |
| Speed | Good if built lean; plugins can slow it | Can be very fast if built well |
| Features | Many plugins available | Built to order |
| Cost drivers | Theme vs custom design, plugins, upkeep | Developer time, content system, hosting |
Security: upkeep decides
The WordPress hardening guide says to keep WordPress up to date and warns that older versions are not maintained with security updates. It says to update plugins and delete ones you do not use, back up regularly, and enable two-step authentication.
That is manageable, but someone has to do it every month. Many law firm WordPress problems come from abandoned plugins and missed updates, not from WordPress itself.
A custom site often has fewer moving parts and no public admin login. It still needs dependency updates and secure hosting. For both, ask who patches the site and how fast. Our guide to website security for service businesses covers the basics.
Speed and mobile
Google's Core Web Vitals page sets the targets: Largest Contentful Paint within 2.5 seconds, Interaction to Next Paint under 200 milliseconds, and Cumulative Layout Shift under 0.1.
WordPress sites can hit those numbers with a lean theme, few plugins and good hosting. Heavy page builders, sliders and chat widgets often push them over. Custom sites start lighter, but a careless build can still be slow. Test the vendor's live sites on a phone before you decide.
Editing and content
Law firm sites grow. You add practice pages, attorney bios, FAQs and articles. WordPress makes this easy for staff. A custom site should include a content system that lets you edit pages without a developer. If it does not, every bio update becomes a ticket.
Ask to see the editing screen during the sales process. If you cannot picture a paralegal updating an office address, keep looking.
Accessibility
The Department of Justice's web accessibility guidance, dated 18 March 2022, says ADA Title III covers businesses open to the public, and that inaccessible websites can limit access to their services. It points to the Web Content Accessibility Guidelines as helpful technical standards. The current WCAG 2.2 Recommendation is dated 12 December 2024.
Neither platform is accessible by default. Themes, plugins and custom components all need testing with a keyboard and screen reader. See our accessibility for law firm websites guide.
Proprietary legal website platforms
Some legal marketing vendors build on their own platforms. These can work well, but check:
- Can you export the site and content if you leave?
- Who owns the domain and design?
- Do redirects and tracking stay in place if you move?
If you cannot take the site with you, you are renting it. Our contract red flags guide covers the clauses to watch.
What drives cost
We do not publish fixed prices; see pricing for how we quote. These factors move the cost either way:
- number of practice area, location and attorney pages
- custom design vs adapted theme
- content writing and attorney review time
- integrations: intake forms, scheduling, call tracking, chat
- multilingual versions
- accessibility testing and fixes
- ongoing maintenance and security
See how much a law firm website costs for more detail.
How to decide
Choose WordPress if:
- your staff will edit pages often
- you want the widest choice of future developers
- you have a maintenance plan, in writing
Choose custom if:
- speed and a small attack surface are top priorities
- you need features plugins cannot provide cleanly
- you have a developer relationship you trust and own the code
Either way, plan the move carefully. Google's site move guidance says to map old URLs to new ones, use permanent server-side redirects, keep them for at least a year, and expect temporary ranking changes.
Questions to ask any developer
Whichever platform you choose, these questions separate a sound build from a risky one:
- Who owns the code, design and content when the project ends?
- Where is the site hosted, and whose account is it in?
- Who installs security updates, and how often?
- How are backups made, where are they stored, and when were they last restored as a test?
- How will staff edit pages, add attorneys and post articles?
- Which plugins or third-party services does the site depend on?
- How do you test speed and accessibility before launch?
- What is the redirect plan for our current URLs?
A clear answer to each, in writing, matters more than which platform the developer prefers. If a developer only builds on one platform, ask why it fits your firm, not just why they like it.

Frequently asked questions
Is WordPress secure enough for a law firm?
It can be, if it is maintained. WordPress's own hardening guide stresses updates, removing unused plugins, regular backups and two-step login. Most problems come from neglected sites.
Do custom websites rank better than WordPress?
Not by themselves. Google measures page experience, content and relevance, not the platform. A lean, well-written site on either platform can perform well.
Can I move from WordPress to custom later?
Yes. Map every old URL to a new one and use permanent redirects, as Google's site move guidance describes. Expect some temporary ranking movement during the switch.
Who should own the code on a custom site?
Your firm. Ask for a written copyright assignment and access to the code repository and hosting. Without them, you depend on one vendor.
Are legal marketing platforms a good option?
They can be convenient. Before signing, confirm you can export the site, keep the domain and keep your redirects if you leave.
Which option is cheaper over five years?
It depends on how often you change the site and who maintains it. WordPress often costs less to edit day to day, while a lean custom site may need less security upkeep. Ask each developer to describe ongoing costs, not just the build, and compare them side by side.
