It seems to me that there is no systemic distinction being made between the legal-terms and terminology tags, and one might usefully be made a synonym of the other. A new "contract-terms" tag might plausibly be created for those questions which are about specific terms in a contract, and not about legal terminology in general.
This was briefly discussed some 5 years ago in Should we delete one of these tags: 'legal-terms' or 'terminology? but there was little comment and no decision. We now have much mnorem data on how the tags have been used.
