Interlineation is a legal term describing the act of adding words, phrases, or sentences to a document between the lines of the original text. This practice is often seen in legal documents, contracts, wills, and other formal writings.

Interlineation Explained

Interlineation is typically used to make minor modifications or clarifications to a document without the need for rewriting or reprinting the entire text.

However, for an interlineation to be legally valid, especially in significant documents like wills or contracts, it usually must be initialed or otherwise authenticated by the parties involved.

This is to ensure that the changes were agreed upon by all parties at the time the modifications were made and to prevent unauthorized alterations.

The Term Interlineation in Different Legal Contexts

Interlineation can have varying legal implications depending on the context and jurisdiction. In contract law, interlineations made without mutual consent or proper authentication can lead to disputes over the document's validity and intentions.

In the context of wills, unauthenticated interlineations may be disregarded during probate, especially if they significantly alter the distribution of the estate, raising concerns over potential forgery or undue influence.

Common Misconceptions About the Meaning of Interlineation

A common misconception about interlineation is that any handwritten addition or alteration to a legal document is automatically valid and enforceable. However, without proper authentication and agreement by the relevant parties, these changes may not be legally binding.

Another misconception is that interlineation is an informal or unprofessional way to amend a document, which is not necessarily true. When done correctly and with full authentication, interlineation is a legitimate method for making necessary adjustments to a document.
