Self-Sourcing is a compliance or borrower-identification field used for eligibility, KYC, legal or regulatory checks. In credit appraisal, it supports identity checks, eligibility validation, regulatory classification, legal due diligence and audit readiness. The field should be supported by documentary evidence and should remain consistent across application data, KYC records and regulatory reporting. For example, leads sourced directly by the bank and leads sourced through partners may follow different verification and accountability checks. It matters because incorrect classification or missing evidence can create regulatory risk, wrong scheme treatment, audit exceptions or delayed approval. The common caution is to rely on verified documents and current regulatory rules rather than informal borrower declarations or outdated master data.
