How do I know if my husband qualifies for social security disability benefits?

You can go to the Social Security Administration website (ssa.gov) and there's a tab you can click on that says "SSI". Once you click on the tab, it will take you to a page that explains SSI benefits and it will give you a phone number to call to start the application process.

For SSI, you need to meet both a medical and an income requirement. It sounds like you meet both from what you've told us.

Good luck!
