Physical data room (PDR) meaning

A physical data room (PDR) is a secure, supervised location set up by a seller, borrower or office‑holder to allow buyers, lenders and their advisers to review original or hard‑copy documents for legal due diligence. It is a descriptive practice term (not generally defined in legislation or case law) used across corporate/M&A, real estate, banking and insolvency work in England & Wales, Scotland, Northern Ireland and Ireland. Typical features include: on‑site access only; an indexed set of documents; admission limited to named individuals under a confidentiality/non‑disclosure agreement; time‑limited appointments; restrictions on copying, photography and removal; attendee and document access logs; and a controlled Q&A process. A PDR protects confidentiality and document integrity, and creates an audit trail of what was disclosed and when. While virtual data rooms (VDRs) predominate, PDRs remain relevant where inspection of originals is required (for example, title deeds, wet‑ink minute books, lab notebooks, technical drawings or prototypes), where regulatory or national‑security restrictions limit electronic transfer, or where cyber‑risk is a concern. Usage is broadly consistent across the UK and Ireland. data protection and confidentiality obligations apply in all cases, and hybrid approaches (PDR alongside a VDR) are common.
