HRS §490:1-308
Keeping your rights when you perform under protest
If you do what the other side asks but say you are keeping your rights, you do not lose those rights. Saying "without prejudice" or "under protest" is enough. This does not apply to a deal that settles a disputed debt.

The statute, as written — Performance or acceptance under reservation of rights
(a) A party that with explicit reservation of rights performs or promises performance or assents to performance in a manner demanded or offered by the other party does not thereby prejudice the rights reserved. Such words as "without prejudice", "under protest", or the like are sufficient. (b) Subsection (a) does not apply to an accord and satisfaction.
