Ownership documents are legal documents that provide evidence of ownership of a property or asset. The two most common types of ownership documents are deeds and titles. A DEED is a written document that transfers the ownership of a property from one person to another. It is usually signed by both parties and witnessed. A TITLE is a document that proves a person's legal right to own a property or asset. It is usually issued by a government agency or other authority. Both documents are essential for establishing ownership of a property or asset.
