I am 64 girlfriend 62 how long will we have to be married so she can qualify for my ss
Hi,
Unless she's already eligible for certain types of Social Security benefits or if she's the mother of your child, your girlfriend would need to be married to you for at least a year in order to qualify for spousal benefits (https://www.ssa.gov/OP_Home/handbook/handbook.03/handbook-0305.html).
In the event of your death, though, your wife could potentially qualify for widow's benefits if you you've been married for at least 9 months leading up to the date of your death, or if she meets one of the exceptions to the duration of marriage requirement (https://www.ssa.gov/OP_Home/handbook/handbook.04/handbook-0401.html).
Best, Jerry
