Final answer:
Title to property passes when a deed is delivered and accepted, which is the moment the transaction becomes legally binding and ownership is transferred.
Step-by-step explanation:
In real estate law, title to property is officially transferred from the seller to the buyer when the deed is delivered and accepted. Therefore, the correct answer to the question of when title actually passes under a deed is C. On the day it is delivered and accepted. The date written on the deed, the day it is executed or signed, or the day it is acknowledged, may all be relevant for other aspects of the real estate transaction, but they do not determine the actual transfer of ownership.
The delivery of the deed must be with the intent to convey the property, and the acceptance is typically presumed if the conveyance is beneficial to the grantee. It is only when both delivery and acceptance have occurred that the title passes, and the transaction is considered legally binding. Until this point, the deed is just a document that signifies the intention to transfer property; it does not by itself transfer the title.
