What is a signature by mark?

A signature by mark denotes the act of indicating consent or agreement through the use of a simple mark, often an "X" or similar symbol, particularly by individuals who are unable to write their names in a traditional manner. This type of signature is a valid form of signature under notary law when the person making the mark is present and intent to sign is clear.

Each individual's ability to provide a traditional signature can vary due to numerous factors, such as literacy, disability, or unfamiliarity with written language. In situations where a person cannot write their name, making a distinct mark is an accepted alternative, thereby allowing them to participate in transactions that require a signature.

The other options are either types of signatures that do not fulfill the specific criteria of a signature by mark or focus on forms of signatures that are different from marking with an "X." For instance, a digital signature is an electronically created signature that fits into a modern context, while a signature made with a pen involves the actual writing of a name, and a signature that includes only initials does not meet the criteria of a signature by mark. These distinctions highlight the unique nature of a signature by mark and its role in notarial practice.
