Rebuilding Palace.legal into a SaaS platform for collective actions, from mockup to code.

Lexprecia since 2015, Palace.legal since 2020, VpourVerdict since 2022: lawyer Arnaud Durand's ecosystem has long carried legal ultimatums. Five collective actions gathered over 300,000 signatories there, and battles were won, from the removal of Linky meters ordered by the Tours court to the reinstatement of a nurse.

The site fulfilled its mobilisation mission. Everything else, membership, files, payment, follow-up, remained manual. We decided to turn it into a platform.

Before the first screen, I laid out the map. The sitemap splits the product into four spaces: a public site that converts a visit into a signature, a member area that retains and manages the file, an admin that operates the service, and the API serving it all.

The architecture sets who does what: the Next.js front end renders the pages and carries SEO, the Django API holds the business logic, PostgreSQL keeps the data, and the orbiting services handle payment, emails, scheduled tasks, social publishing and KPIs.

The Figma mockup stayed deliberately light: the journeys, the templates, the charter. The real work happened in code, with AI as a production tool: I built the complete front end in Next.js on the Django API, multilingual and pre-rendered page by page.

The action page concentrates the mechanism: the counter and its goal, the petition text, the sourced evidence (EU General Court, Constitutional Council), the milestones that trigger each legal step, and one-click signing.

A legal service is not allowed to promise an outcome. The design owns that constraint instead of disguising it: the hero announces "transparency, GDPR, no promise of result", and everything displayed is a verifiable fact: signatures collected, each action's velocity, testimonials stated as concrete outcomes (€340 recovered, €4,800 of overcharged rent refunded).

The journey is told in five steps, from signature to compensation, and commitment rises in tiers: signing is free and immediate, joining unlocks follow-up and party-to-the-procedure status, collecting comes with success. Dark mode is native, on a par with light.

Search, theme filters, action cards with counters and signature velocity, multi-channel sharing: every screen pushes towards the signature, on desktop and mobile alike. Content, blog, FAQ, press, marketing pages, lives in the CMS and serves acquisition.

The member account automates what used to be manual: onboarding, tracking joined actions, milestone notifications, building the claimant file, payments and reminders. The plans, from Mini to Aura, fund the procedures, with shareable seats and a built-in referral code.

Behind the scenes, the admin covers the CMS, the CRM of members and claimants, and the KPI dashboards: signatures, conversion, revenue.

Fourteen scheduled tasks keep the service running without intervention: 33 lifecycle emails, payment reminders, notifications, newsletters, scheduled content and automated publishing to twelve social networks. SEO is handled in depth: pages pre-rendered per language, structured data, sitemaps.

The complete demo is public, and the launch is being prepared at wejustice.fr: the historical actions, from the Linky ultimatum to the vaccine contracts, find their signatories there again.
