What does it mean to assert a need? To express a need? To exercise a need? Or something else?
See, e.g., Kichesipirini Assert Need for Legal Empowerment | The Dominion.
Technically the word 'assert' has to do with speech, so "express a need" is accurate. Some people these days use the word 'assert' to mean that something was done (exercise a need), though this is not strictly correct.
