This article examines the legal position of a digital twin linked to an identified physical property. It rejects two shortcuts: treating the twin as a mere engineering file and treating it as a second immovable asset existing alongside the land or building.

The study therefore distinguishes the physical property from the model, data, software, platform service and land-register entry, and tests the twin’s functions throughout the property lifecycle. Depending on its contractual and institutional setting, the twin may operate as a description of the property, a conformity model, an accessory to be delivered, a continuing digital service, evidence of a technical fact, or a composite bundle of rights and obligations.
Under Iraqi law, the twin may support evidence and property management, but title transfer remains subject to official registration under the Civil Code and the Real Estate Registration Law.
