Disabled adult child benefit and onset date

It sounds like you're navigating through a complex situation with Social Security benefits, aiming to understand how your work history impacts your eligibility for SSDI on your deceased father's record. Generally, to qualify for Disabled Adult Child (DAC) benefits on a parent's Social Security record, your disability must have started before you turned 22. Your work history prior to the onset of your disability is a crucial factor, but the key is whether your disability started before reaching this age. Since you mentioned that your disability onset date was in 1991 and you worked in 1989, your eligibility for DAC benefits primarily depends on whether your disability began before you were 22. The Social Security Administration (SSA) looks at the onset date of your disability to determine if you meet the criteria for receiving benefits on a parent's record. Working before your disability onset does not disqualify you, provided your condition began before the specified age limit. Understanding these nuances is essential for navigating the benefits process. If your disability did start before you turned 22 and you are now applying for SSDI based on your deceased father’s record, your previous work might not impact your eligibility for DAC benefits. However, every situation is unique, and the SSA considers various factors when reviewing applications. It might be beneficial to discuss your specific circumstances with someone familiar with Social Security policies or reach out to the SSA directly for clarification and personalized advice.
