Final answer:
Before the title is passed, the required event is the completion of documentation. This process involves legal documents and is often overseen by an escrow service. Documentation is what legally facilitates the transfer of title.
Step-by-step explanation:
The event that must happen before the title is passed is documentation. The process of transferring title to property is detailed and requires the completion of legal documents, often facilitated by a neutral third party known as an escrow. The escrow ensures that all conditions of the transaction are met before the title and money are exchanged. This process includes the preparation and signing of documents, performing a title search, obtaining title insurance, and recording the transfer with the appropriate government body. Payment, inspection, and negotiation are also important steps, but they typically precede the finalization of documentation.
