As long as you meet the qualifications for SSDI, you can still receive benefits even if you received a substantial personal injury settlement. The reason why is that SSDI is based on your work history and work credits, not your income. For example, let’s say your Las Vegas slip-and-fall attorney reaches a settlement, and you receive a slip and fall case payout of several million dollars. Even though you are now a millionaire, you can still apply for and receive SSDI benefits.
