Their use is subject to applicable lending, fair-lending, and notice requirements; model scores are not legal determinations.
Credit-underwriting models estimate risk or support lending decisions and remain subject to applicable fair-lending and notice requirements. Current Regulation B at 12 CFR 1002.9 governs adverse-action notices. A notice may provide the specific reasons or explain the applicant’s right to request them; when a creditor supplies a statement, it must give specific principal reasons that accurately describe factors actually used. CFPB circulars issued in 2022 and 2023 that discussed complex algorithms were withdrawn on May 12, 2025; they are historical guidance, not current authority. Features associated with protected characteristics can raise proxy-discrimination risks, but correlation alone does not establish unlawful disparate impact. Legal analysis depends on applicable rules, evidence, and facts. Thin-file applicants have little traditional credit history; relevant alternative or cash-flow data may help assess some applicants, subject to validation, coverage, and fair-lending controls. SHAP assigns feature-importance values to an individual prediction under specified assumptions; it is not causal proof or a legal explanation by itself.

A feature can act as a proxy when it is associated with a protected characteristic or group. That association may raise fair-lending risk, but whether a practice violates law depends on the facts, evidence, and applicable legal standards; correlation alone is not an automatic legal conclusion.
An adverse-action notice informs the applicant that the creditor took an adverse action on the application.

SHAP assigns feature-importance values to a particular prediction under its model and background assumptions. Those attributions describe model behavior; they do not by themselves establish that a feature caused the outcome or that the decision is legally fair.
