The portal is built as a client-facing layer over the firm's existing practice management system, reading matter, document and billing data through that system's API rather than holding a separate, potentially divergent copy of the matter record.
A presentation layer sits between the raw practice management data and what the client sees, applying privilege tagging, fee estimate formatting and status curation, so internal-only detail never reaches the client view by default and has to be explicitly included.
Document storage uses encryption at rest and in transit, with access governed by matter-level permissions that mirror the firm's own file access controls, so a client can only ever see documents tied to matters they are a party to.
E-signature and identity verification are integrated as adapter services, so the portal can support DocuSign or Adobe Sign, and whichever identity verification provider the firm already uses, without the core portal logic depending on any one vendor.
