What characterizes a blank endorsement?

A blank endorsement is characterized by the presence of no words except for the endorser's signature. This type of endorsement essentially transfers ownership of the instrument, such as a check, to the bearer without any additional instructions or restrictions. By simply signing the back of the document, the endorser allows anyone in possession of the endorsed item to claim it, making it transferable to anyone else without the need for further endorsement. This facilitates easy transferability, which is why it is commonly used in financial transactions.

The other options do not accurately capture the essence of a blank endorsement. A detailed instruction document does not relate to the simplicity and transferability that a blank endorsement provides. Similarly, a written disclosure of terms of a contract refers to something much more complex than a simple signature on a piece of financial paperwork. Finally, a notarized agreement involves an official witnessing process, which is not a requirement for a blank endorsement.
