Legal Website + Mobile Design

What we do

Your website is the anchor of your company's digital presence and often the first point of contact with potential customers. As the legal industry migrates to the digital space, we believe it's crucial your site be not just a placeholder with a contact button but a platform to expand your business.

One400`s award-winning team designs striking websites that elevate your company's profile online, clearly defining your strengths and attracting new clients in a rapidly growing and increasingly competitive field. On every website project, we focus on “mobile-first” optimization, aesthetically engaging design, and adaptability to your business goals and aspirations.

At the visual level, we'll integrate your site with a brand identity that affirms your company's mission and distinguishes you from competitors with the best legal website design. We emphasize clarity and a customer experience that's both welcoming and informative. Our team can provide original graphics, custom photography, and consultation for your own in-house marketing team.

In keeping with our mission to increase access to legal services, we'll make your site fast and functional on all devices—a key avenue for growth—with responsive or adaptive design. Our developers employ highly adaptable site architecture, enabling cost-effective, dynamic upgrades and add-ons for new business channels—apps, payment portals, and other interactive features. We can also optimize site accessibility to meet ADA standards, enlarging your customer base and supporting equal access for legal aid. ONE400 also provides reliable, secure web hosting.

All our work is unified by the highest standard of customer service and institutional knowledge of the legal industry. In partnership with your firm, ONE400 advances your online case from theory to reality.
