01 — The ranking
The Rome board
Use this Rome board as a structured view of the best law firms in Rome. Tiers name relative standing in words; the REF codes locate rows for citation, and within-tier order is deliberately non-hierarchical.
The top editorial band for Rome: firms that anchor deal flow, disputes and advisory work at scale. Within-tier sequence rotates and is not a ranking.
Highly active on the Rome board means consistent market presence and peer recognition short of the leader set. No numeric score is assigned.
Notable in this field marks verified Rome presence below full tier depth — specialist or thinner benches kept visible on purpose, not scored into the main bands.
All counts are shown as bands, never precise headcounts. Notable firms sit outside the tiers by design: verified minimal presence, not assessed at full tier depth.

Methodology
How tiers are assigned
Deterministic public-footprint core (local depth, practice share, seniority mix, public hiring momentum), computed relative to this market's own distribution. Tier placement is derived from this public mapped data; a per-firm public-source ledger is compiled for firms in the annual research pass and applies to those firms' factual claims, not to tier membership. No third-party legal-directory bands are used as an input.
Market scope
5–9 firms earn a tier in Rome within this scope (banded).
