At full retirement age (66) I filed and suspended my benefits. I have a son school age and he received dependent benefits. I am now turning 70 in July and will receive my full benefits. My son is 18 but has one more year of high school. SS states he will continue with benefits until completion of high school June 2018. Two questions: Will my son continue to receive benefits although I will receive my benefits when I turn 70 in July? Question number two. Will I be eligible for the 6 month retroactive payment? SS office I visited said yes.
