An unrecorded deed may be valid between the grantor and grantee if properly executed, delivered, and accepted, but it does not give constructive notice to third parties through the land records. Constructive notice arises from proper recording, allowing later purchasers, lenders, judgment creditors, and title examiners to discover the ownership claim. A deed must still name the parties and contain an adequate legal description to identify the property. The false assumption is that recording is required for validity between the original parties; recording is mainly about public notice and priority protection. Pennsylvania recording law protects later bona fide purchasers, mortgagees, and judgment holders against unrecorded instruments lacking actual or constructive notice.
