First of all my condolences on the loss of your husband. I know this must be a difficult time for you. It's always hard when you lose a Spouse, especially after 52 years of marriage.
Are you receiving Social Security benefits from your own Social Security earnings record or are you receiving Spousal benefits under your husbands earning record?
At this point, all you have to do is to call Social Security to inform them that your husband has passed away. They will make the appropriate adjustment in your benefits and have them direct deposited wherever you wish, perhaps where your benefits are being deposited now.
You will be entitled to the higher of your husband's full retirement benefit as of his full retirement age your own benefit based upon your own earnings record, but not both benefits.
In many cases the funeral director will notify the Social Security Administration (SSA) of your husband's death, so you may want to check on that before you call the SSA yourself as sometimes the wait on hold on the telephone can be quite long.
If you need to contact the SSA, you may do so at the following number:
Call the SSA toll-free number, 1-***-***-****, between 7 a.m. and 7 p.m.
