Records Retention Guide

A well-organized digital document library uses a consistent folder structure that reflects how your organization works — by business function, client, project, or document type. The best structure is the one your team will actually use, because an abandoned structure is worse than no structure at all.

Design the structure with retrieval in mind. Documents should be findable by someone who did not create them. Common approaches: top-level folders by department or business function, then by year, then by project or client. Avoid creating folders for individual people — this creates silos that become inaccessible when employees leave.

• Use consistent folder names without special characters
• Keep folder hierarchies shallow (3–4 levels maximum) to reduce navigation complexity
• Create an index document at each top-level folder explaining its contents
• Archive completed project folders rather than deleting them immediately
• Designate clear ownership for each top-level folder

Without version control, contract negotiations, document revisions, and policy updates quickly generate a confusing set of files with names like “contract_final_v3_REVISED_use this one.docx.” A clear versioning convention eliminates ambiguity about which version is current.

A simple version numbering system: use v1, v2, v3 for major drafts circulated for review, and v1.1, v1.2 for minor edits within a draft cycle. Include the date when the version was created in either the filename or the document properties. Mark the final executed version clearly and archive all earlier drafts together with it.

For documents under active negotiation or revision, a document management system with built-in version history (SharePoint, Google Drive, or a dedicated DMS) is more reliable than manual file naming conventions. These systems retain every save as a recoverable version and log who made each change.

Access controls determine who can view, edit, and delete documents. Principle of least privilege: users should have the minimum access level needed for their role. Over-permissive access creates data exposure risk; under-permissive access creates operational friction and workarounds that undermine security.

Review access permissions when employees change roles or leave the organization. Departed employees with lingering access to sensitive documents represent a data security and compliance risk. Establish an offboarding checklist that includes revocation of document access alongside other system credentials.

A retention schedule specifies how long each document type must be kept and what happens to it after that period. Retention periods are driven by legal requirements (tax records, employment records, financial statements), contractual obligations (document retention clauses in agreements), and business need (operational reference, institutional memory).

Common retention periods by document type (verify applicable requirements for your jurisdiction and industry):

These are general guidelines only. Consult legal counsel for retention requirements specific to your industry, jurisdiction, and regulatory environment.

When a document reaches the end of its retention period, it should be deleted rather than kept indefinitely. Retaining documents beyond their required period increases storage costs, expands your data breach exposure surface, and can complicate litigation — documents retained past their normal retention period may be discoverable in legal proceedings.

Secure deletion means ensuring that data cannot be recovered after deletion. Moving a file to the trash and emptying it is not secure deletion — the underlying data often remains on storage media until it is overwritten. Use appropriate deletion tools for your storage environment, and maintain a destruction log recording what was deleted, when, and by whom.

For paper documents that have been digitized but not yet destroyed, establish a verified destruction process. Consider professional document destruction services that provide certificates of destruction, particularly for documents containing personally identifiable information, financial records, or other sensitive content.

Backups protect against accidental deletion, ransomware, hardware failure, and other data loss events. Document your backup policy: what is backed up, how frequently, where backups are stored, how long backup versions are retained, and who is responsible for monitoring backup health.

Backup retention must align with your records retention schedule. If a document has a 7-year retention requirement and you only keep 90 days of backup history, a deletion event more than 90 days ago cannot be recovered. Calibrate backup retention windows to your longest-retention document categories.
