nachtraglich

Nachtraglich is a German term used as an adjective or adverb to denote something added after the fact. It describes additions, amendments, or adjustments that become part of a document, agreement, or situation only after the original event or period, and may imply retroactive applicability. The term is common in legal, administrative, financial, and organizational contexts.

In contract law, nachtraglich refers to an addendum or amendment entered into after the original contract has been signed, and that becomes binding when agreed by the parties. In accounting or billing, nachtragliche items are charges, credits, or items that are recognized or billed after the initial invoice or service was concluded. In claims or benefits contexts, nachtragliche Forderungen describes claims or adjustments asserted post hoc or applied retroactively.
