Interlineation Legal Meaning and Definition

Here is a simplified definition of the legal term Interlineation.

Interlineation (noun):

The act of adding or modifying text within the lines of a previously written document, such as a contract or other legal instrument. This may occur due to omissions in the initial draft, or reconsiderations made at a later time. These alterations can alter the original contract and therefore must be agreed upon by all parties involved, typically indicated through initials. Ultimately, the document is typically retyped to integrate the new information. Interlineations are the sentences or lines added or altered in this way.
