Benefits for Spouses. When a worker files for retirement benefits, the worker's spouse may be eligible for a benefit based on the worker's earnings. Another requirement is that the spouse must be at least age 62 or have a qualifying child in her/his care. By a qualifying child, we mean a child who is under age 16 or who receives Social Security disability benefits. The spousal benefit can be as much as half of the worker's primary insurance amount, depending on the spouse's age at retirement.
