Receiving Deceased Parent's Social Security Benefits?

If your mother was receiving Social Security benefits from having a work record then yours and your brothers ages will determine if you are entitled to draw any benefits. But, if you were under 19 and still in high school then it seems your mother would have been drawing a check for each of you before she died.

There are several types of SS benefits and it is possible your mother was drawing SSI benefits and if that were the case, then there would be no benefits available for anyone no matter the age.
These are some of the reasons it is so important that you go to the SSA and inquire about your mother's and possibly your benefits.
There is also a $255 burial/death benefit but most likely the funeral home took care of this. You can check the papers from the funeral home or give them a call and ask. If they did not receive this benefit then they can tell you how to place a claim with SSA.
I believe that both of you may be past this age so if you are, then, as far as SS is concerned you may not be eligible.
You should check this out with SSA just to be sure. You will need your mother's Social Security number (and yours) and SS may require a birth certificate but they will tell you what you need when you visit their office.
If your mother received a "back payment" and still has money in her bank account then you may need to see and attorney to be able to reach this money. That will also go for any type of property she may have - such as a car or home or any stocks or bonds.
As for her incidental personal belongings that may be laying around where she lived then most likely there would be no problem if you and your brother decide what happens to these things between yourselves.
I would hope that you and your brother would want some of your mother's things if for no reason but in remembrance.
Good luck to you and your brother but be sure you go to the SSA office and make inquires and right now is probably the best time.
