Document Custody & Integrity FAQ

Frequently Asked Questions

Frequently asked questions about document custody & integrity, operational workflows, and security.

How does Lexuno verify document integrity?

Every uploaded file generates a SHA-256 cryptographic checksum at ingestion, creating an immutable fingerprint that verifies the file remains unaltered.

Can we keep internal notes and drafts private from clients?

Yes. Lexuno enforces strict visibility boundaries. Internal drafts remain private to firm staff until explicitly published to the Client Portal.

Does Lexuno support large file and bundle uploads?

Yes. Lexuno uses secure chunked multipart uploads with presigned tokens, accommodating large PDF trial bundles, evidence scans, and records.

Can we compare different versions of a legal contract?

Yes. Built-in revision history and visual diff tools allow attorneys to compare changes between successive draft iterations.

What file formats and storage limits are supported in Lexuno?

Lexuno supports all standard legal document types including PDFs, Word documents, spreadsheets, and scanned evidence bundles, with pooled storage that can be expanded on demand.
