hereon

Hereon is an English adverb used chiefly in formal or legal writing to mean on this document or instrument, or on this matter. It refers to components, terms, or provisions that appear on the current instrument. In normal prose the term is rare and may read as archaic or ceremonial, but it remains standard in some contracts and deeds for precision.

Etymology and history: The word is a compound of here and on and derives from Middle English usage. It has appeared in legal and official texts since the early modern period and continues in some jurisdictions, though its use has declined in everyday English.

Typical usage: In drafting, hereon may appear in phrases such as The terms set forth hereon shall be binding on the parties, or The date hereon shall be the effective date. This usage anchors clauses to the text or date displayed on the instrument itself. It should not be confused with hereinafter (from this point forward), herein (in this document), or hereof (of this document).

Notes: For clear, plain English, many writers prefer alternatives like on this document or from the date shown. Use of hereon is generally restricted to formal or traditional legal prose, where readers will expect such terminology.
