Lien

A lien, in the personal injury context this platform models, is a legal claim asserted against a claimant's eventual settlement or judgment proceeds, typically by a medical provider, a hospital, a health insurer through subrogation, or another party with a financial interest tied to the claimant's treatment or recovery. Liens are usually treated as an administrative detail negotiated down at settlement, but examined across a large corpus of resolved matters, the pattern of how liens are asserted, negotiated, and ultimately reduced carries real predictive content: lien size and provider aggressiveness often serve as an early, structured signal for injury severity and treatment duration, both of which independently correlate with a matter's eventual settlement value and time to resolution. Lien data also matters for a separate and distinct calculation, net-to-claimant proceeds, since a capital provider sizing a pre-settlement advance against gross settlement value alone, without accounting for typical lien consumption in that matter's provider and injury profile, systematically overstates what will actually remain to satisfy the advance. Building a reliable lien corpus is harder than building a court-record corpus, because there is no standardized public reporting mechanism for medical liens, and the same underlying medical event frequently generates multiple, overlapping lien records that must be reconciled into a single deduplicated event before the corpus can be counted honestly.
