Redesigning and Modernizing a Legal Document Platform

UI/UX Design Front-End Consulting AI-Assisted Workflows

FiftyFive redesigned a UK legal technology firm’s automated document-generation platform, rebuilding its information architecture, workflows, and design system. The redesign integrated AI assistance into document flows, reduced cognitive load, and delivered an engineering-ready component library, cutting document creation time by 60%.

The Client

Overview

The client is a UK-based legal technology firm specialising in automated document generation. Its platform supports businesses that need streamlined, compliant, and user-friendly workflows for complex legal paperwork, where interface clarity directly affects adoption and operational efficiency.

The Need

Challenges

The document-generation platform had grown faster than its interface could support. Usability problems across structure, workflows, lifecycle visibility, and AI integration were limiting adoption and slowing internal operations.

  • Complex interface structures lacked clear grouping logic, forcing users to retain too much context during routine tasks.
  • Low-affordance admin screens made task order, field priority, and completion states difficult to understand.
  • Users could not easily identify document lifecycle stages or the people acting on each document.
  • Inconsistent labels and interaction patterns increased learning time and support requirements.
  • AI capabilities sat outside the natural workflow and interrupted document creation.
  • Missing status, navigation, and orientation cues left users unsure of their progress.
Our Approach

Solution

FiftyFive restructured the platform around how legal documents are created and reviewed. Through agile sprints, user testing, and iterative design, the team rebuilt information architecture, admin workflows, AI-assisted input, collaboration visibility, and a reusable design system with engineering-ready specifications.

Rebuilt information architecture

FiftyFive restructured content and navigation so users can locate functionality without relearning the interface during each session.

  • Card sorting established grouping logic around user mental models.
  • Hierarchical layouts separated primary and secondary actions.
  • Optimised content grouping reduced decisions per task.

Customisable administrator panels

FiftyFive redesigned administration around structured, predictable task flows instead of dense and undifferentiated forms.

  • Structured inputs make task order and completion explicit.
  • Improved information density balances detail and readability.
  • Panels can be configured for different administrator responsibilities.

Progressive disclosure in templates

FiftyFive staged complex legal inputs so advanced and conditional fields appear only when relevant.

  • Long template forms are divided into contextual steps.
  • Advanced fields are revealed on demand.
  • Cognitive load falls without removing legal detail.

AI-assisted interface workflows

FiftyFive moved AI features into the document-creation flow instead of presenting them as separate tools.

  • Contextual microinteractions surface help at the point of need.
  • Guided prompts help users provide correct information.
  • AI suggestions remain within structured document workflows.

Atomic design system

FiftyFive built a reusable design system to support consistent interfaces and future product development.

  • Atomic components cover states and interaction patterns.
  • Microcopy and interactions align with usability heuristics.
  • Reusable patterns shorten design and build cycles.

Collaboration and lifecycle visibility

FiftyFive made document status and collaborative activity visible throughout each workflow.

  • Real-time indicators show active participants.
  • Status badges reflect document lifecycle stages.
  • Progress tracking and wayfinding restore orientation.

Engineering-ready handover

FiftyFive delivered component-level specifications and libraries that the client’s engineering team could implement directly.

  • UI specifications are documented at component level.
  • Component libraries support front-end implementation.
  • Front-end consulting supports future feature rollout.

FAQs

A legal document automation platform generates contracts, agreements, and legal paperwork from structured templates and user inputs instead of manual drafting, while supporting accuracy, compliance, and version control.

Legal workflows carry high cognitive load, compliance requirements, and long forms. Clear UX reduces errors and document creation time while improving user confidence, product adoption, and support efficiency.

Restructured information architecture, progressive disclosure, clearer task hierarchy, and contextual AI prompts reduce unnecessary decisions. In this engagement, the redesign reduced document creation time by 60%.

Progressive disclosure reveals information and fields only when they become relevant. It reduces cognitive load in complex legal templates while preserving conditional clauses and advanced document details.

A design system is a documented library of reusable components, states, interaction patterns, and microcopy rules. It maintains consistency and gives engineers reliable specifications for future development.

AI features should sit inside existing workflows through contextual microinteractions, guided prompts, and structured flows, keeping assistance available at the point of need without interrupting the user’s task.

The System Usability Scale is a standardised ten-item questionnaire producing a comparable usability score. Teams use it to measure perceived usability before and after a redesign.

Component-level specifications and atomic libraries give engineers reusable patterns instead of isolated screens, shortening development cycles, reducing rework, and supporting consistent feature rollout.

Front-end consulting covers component architecture, UI specifications, design-system implementation planning, and guidance on how interface decisions affect build effort and implementation accuracy.

Offshore design teams work effectively through agile sprints, shared reviews, user testing, time-zone alignment, and documented handover that keeps design decisions visible to in-house stakeholders.

Timelines depend on workflow count, template complexity, research requirements, and whether a design system is included. Redesigns are typically scoped across iterative agile sprints.

Cost depends on the number of screens and workflows, research depth, design-system scope, and front-end consulting requirements. Flexible engagement models allow scope to change with product priorities.
