I am 58 and receive SSDI and SSI. If I get married will I lose any of my benefits such as the SSI, medicare, medicaid or food stamps?

You will not lose SSDI and Medicare but you might lose SSI, Medicaid and food stamps if your husband has income.  Depends upon the amount of his income.  In regards to resources, a married person is allowed up to $3000 of countable resources.  SSI doesn't count the value of the home you live in nor one motor vehicle.

SSI is a federal welfare benefit.  That means it is based upon financial need.  SSDI isn't a welfare benefit; your spouse's income has no impact whatsoever on your entitlement to SSDI or the benefit amount.  SSI and SSDI and two entirely different types of programs.

If you would lose SSI, Medicaid and food stamps because of his income, that would mean you would be better off financially then someone who gets married and continues to be entitled to those benefits.

I was a SS claims rep for 32 yrs.

no. you have to be related in some way that takes away your independence. 

I dont know where people get that idea but your spouse is not a parent.

only way would be if he/she declared you a "dependent" on your tax return.

then you'd be his/her "child".

your getting married not born.

Depends on the income level of your spouse.
