FAR and DFARS › FAR Part 52: Solicitation Provisions and Contract Clauses › Subpart 52.2
FAR 52.215-19 Notification of Ownership Changes.
The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.
In plain English
This clause requires a contractor to notify the Administrative Contracting Officer in writing within 30 days of learning about an ownership change that could affect the valuation of its capitalized assets, or of related changes to asset valuations or costs. It also requires the contractor to keep accurate asset and cost records, give the ACO access to them, and flow the clause down to certain subcontracts. It matters because ownership changes can affect how assets are valued in the contractor's accounting records, and the government wants timely notice and reliable records.
Applies to: Contractors subject to FAR 15.408(k) and their applicable subcontracts
What it requires
- Notify the ACO in writing within 30 days of becoming aware of an ownership change that could change capitalized asset valuations
- Notify the ACO within 30 days of asset valuation or other cost changes resulting from an ownership change
- Maintain current, accurate, and complete inventory records of assets and their costs
- Provide the ACO or designated representative ready access to those records upon request
