Question:
Does a ninety year old widow , not intending to remarry and husband was childless, need chalitza?
Answer:
Yes, the mitzva of chalitza is not just in order for her to remarry, but an independent mitzva. In fact it is a rare special mitzva, and when it is done, numerous people come together to watch it being done. It is a mitzva that she will only do once in her life, and although it is because of unfortunate circumstances, it is still a mitzva nonetheless.
Best wishes
