How to draft a lawsuit with legal AI: step-by-step guide for lawyers (2026) : Lexiel

# How to draft a lawsuit with legal AI: step-by-step guide for lawyers (2026)

Drafting a lawsuit is a sequence of interdependent decisions: choosing the right procedure, structuring the facts, grounding the brief in law, calculating amounts, and generating the final document.

Step 1: Choose the correct procedure

Civil law (Arts. 249-250 LEC):

Ordinary proceedings: amount > €6,000 or special matters
Summary proceedings: amount ≤ €6,000 or possession, leases
Enforcement: when a title already exists

Labor law: ordinary process (Arts. 76-97 LRJS) or special processes for dismissal, wage claims, fundamental rights.

Lexiel's procedure determinator applies these rules automatically from your case description.

Step 2: Case file and data

In Lexiel, each lawsuit is generated from an active case file: auto-fill of party identifying data, automatic amount calculation with late interest (Art. 576 LEC), deadline calendar for prescription verification.

Step 3: Procedure template

Lexiel has 39 procedure types across civil, labor, commercial, and administrative law, each with predefined structure, auto-filled placeholders, and baseline case law citations.

Step 4: Legal grounding: where AI makes the difference

Generalist LLMs frequently cite outdated article versions or invent non-existent judgment numbers.

Lexiel retrieves the 8 most relevant BOE and CENDOJ citations, verifies currency with indexing dates, applies normative hierarchy automatically, and formats citations in standard forensic format (ECLI, rapporteur, chamber).

Step 5: Review and adjustment

The Lexiel draft covers 70-80% of the brief. The remaining 20-30% is your contribution: specific case factual narrative, litigation strategy, and judgment on which case law carries most weight with the specific court.

Step 6: Export to Word or PDF

Standard Spanish judicial document formatting: margins, numbered facts and legal grounds, attorney signature block.

Time saved: real example

Task	Without AI	With Lexiel
Procedure selection	30 min	2 min
Case law research	2-3 h	5 min
Draft brief	3-4 h	15 min
Review & adjust	1 h	30 min
Total	6-8 hours	~1 hour

At €150/hour, that's €750-€1,050 of recovered value per brief, versus €69/month for the Starter plan.

Conclusion

Specialized legal AI multiplies lawyer output capacity. A lawyer who previously drafted 2 complete briefs per day can do 8-10 with the same quality, because the research and grounding phase shrinks from hours to minutes.
