Family Member Hospitalized. I need to end their lease.

One of my siblings had a major medical emergency and was hospitalized for nearly a month. He cannot return to his apartment as he needs round the clock care and can’t work. Is it possible for me to break his lease on his behalf?

Right now he’s not capable of speaking to the leasing office or handling any of his business affairs. I’m not sure what to do about his apt. He lives in NC.
