Source Corroboration
Source Corroboration means Confirming a finding with independent sources or identifiers rather than relying on one database, post, or record.
This page explains source corroboration through LPIIA’s fact-first operating standard. It covers lawful scope, preparation, methods, reporting, sources, local context when applicable, and the limits a client or attorney should understand before assigning the work.
Plain-English Definition
Confirming a finding with independent sources or identifiers rather than relying on one database, post, or record.
Why the Term Matters
In an investigation, source corroboration affects how information is collected, evaluated, preserved, or reported. Using the term correctly helps clients and attorneys understand whether a result is a lead, a verified fact, a method, a source, or a limitation.
Common Misunderstanding
A frequent mistake is treating source corroboration as proof of more than it actually establishes. Professional work identifies the source, date, jurisdiction, identity indicators, competing explanations, and the specific conclusion the information supports.
Practical Example
A proper use of source corroboration would document the input, method, result, and limitation. The report would avoid unsupported certainty and would identify what additional corroboration, authority, or specialist review is needed.
