At age 62 my husband medically needed to take his SS Disability. At age 66 1/2, I took half of his as spousal benefit. I’m now 68 and stopped working. I’m waiting until I’m 70 to take my SS. Question is, do I need to notify SS that I’m retired? Do I now have to take my own SS? We are doing ok on his SS and Spousal Benefit. It was my intention to wait to take my SS until at least age 70. Please advise.
