Meaning in plain English
In plain English, thereunder points to the authority or terms of something named earlier. Obligations thereunder are obligations under the document, rule, or agreement just mentioned.
Tone, context, and nuance
Thereunder is precise in legal drafting but stiff elsewhere. If your reader is not parsing clauses, “under it,” “under the agreement,” or “under those rules” is usually clearer.
Example sentences
- Simple: The contract and the duties thereunder remain in effect.
- Everyday: “The duties under the contract” is clearer than “the duties thereunder.”
- Legal: The license and all rights granted thereunder may be terminated.
- Nuance: Thereunder depends on a clear earlier noun.
- Awkward: “I put my shoes thereunder.” Better: “I put my shoes under it.”
