Which type of evidence is considered extrinsic evidence?

Extrinsic evidence refers to information that comes from outside a document or a specific matter being addressed, providing context or additional support for the case at hand. This type of evidence is crucial in legal discussions because it helps clarify intentions, clarify meanings, or provide supporting details that are not contained within the primary documents themselves.

Choosing evidence derived from external sources accurately captures the essence of what constitutes extrinsic evidence. It is distinguished from intrinsic evidence, which comes from within the document itself, such as clauses within a deed or testimony directly related to the parties involved in a contract or situation.

The other options illustrate different forms of evidence but do not fit the definition of extrinsic evidence. For instance, testimony from eyewitnesses is based on personal observations and is more intrinsic to the event in question, while documentation found in a legal deed is contained within that legal context and is not considered external. Similarly, physical artifacts refer to tangible objects relevant to a situation but again do not represent the external sources that characterize extrinsic evidence.
