Law as Code in Practice: French Family Benefits
One Family, One Executable Model — and What It Gives the Fund
Law as Code by Country · Volume 1

Edition 2026.10, 2026-10-12. Published by Arxo.

First of all a demonstration of what modelling legislation with Arxo can do: an independent model built from published French law; it does not claim legal accuracy or completeness, it is not an implementation by or for the Cnaf, and its answers are not legal advice. The families and cases in this book are fictional.
