Built an AI legal-triage tool for Spanish property owners facing illegal occupation

August 4, 2026

Hey IH — wanted to share what I've been building.

In Spain, if someone occupies your home illegally, your first move usually isn't a lawyer — it's confusion. Which of five very different legal situations are you actually in (allanamiento, usurpación, a tenant who stopped paying, a lease that expired, a precario)? Each has a different legal process and timeline, and getting it wrong wastes months.

LexData takes a property owner through a short guided questionnaire, gives them a free viability read on their case, and — if they want to go deeper — generates a €25 PDF dossier: the diagnosis, the realistic procedure and timeline (based on real CGPJ court data, not guesses), and what to do next. If they want a lawyer, we can optionally connect them to a partner through a marketplace — that side monetizes separately from the lawyer, not the property owner.

Stack: React/TS frontend, Python + LangGraph + OpenAI for the triage/report pipeline, Supabase, Stripe. Live in production at lexdatalegal.com, Spanish only, Spain only.

Early days — real payment flow, real legal-data pipeline, still building up real usage. Happy to answer questions about the legal-tech angle, the AI pipeline, or the build itself.

This is an interesting use case for legal technology because the real value of triage may be helping people understand what their next step should be before they spend time and money pursuing the wrong one. At the same time, tools dealing with property disputes need to be particularly careful about jurisdiction, factual accuracy, privacy, and the limits of automated legal guidance. Technology can improve access to legal information, but meaningful human legal review remains important when rights and property are at stake.

The separation between the free viability read, paid dossier, and optional lawyer connection is interesting.
Since the product is live but usage is still early, have you seen people naturally move through that full path yet, or is that still the main thing you’re waiting to learn?

  Good question — and honestly, that's exactly the thing we're still learning. Usage is early enough that I don't yet have a confident read on whether people naturally flow through the whole path (triage → dossier → lawyer connection), or whether there's a specific point where most people stop.
  Right now I'm doing two things in parallel: watching the funnel numbers (where people drop before paying, whether people who get the dossier follow through to the lawyer marketplace) and talking directly to users to understand the "why" behind the drop-offs — the data tells you where people leave, not always why.
  My working guess is that the biggest drop is at the paywall (free triage → €25 dossier), but I'm not committing to that until I have enough real signal. Happy to share what I find once there's a clearer pattern.

    That’s helpful context. I appreciate you being open about what you know versus what you’re still trying to validate.
    I’d like to continue the conversation outside the thread. What’s the best email to reach you on?
