Contract Pattern Library

37 named structural patterns extracted from 107 attorney interviews and MCLE war stories. Lawyers in trucking, healthcare, SaaS, and construction were all describing the same contract traps — using completely different vocabulary. We cataloged them.

Each pattern has two names: what the drafter calls it, and what the other side is actually agreeing to.

About the Corpus

These patterns were identified through 107 attorney interviews and MCLE war stories collected across a dozen industries. The core finding: contract disputes in trucking, healthcare, SaaS, and construction describe the same structural traps — but practitioners in each field had developed entirely different names for them.

This library is original LawSnap research. It is not based on secondary sources. Each pattern is named from the drafter's perspective and the responder's perspective simultaneously, because the same clause reads as two different contracts depending on which side you are on.
