My son was killed in an accident involving a drunk driver. He never had a job. If I file a wrongful death lawsuit, will it be thrown out because he never held a job?

No. It does not matter if the victim ever held a job. He or she likely contributed to the family unit in some manner. An example would be a mother who remains at home to care for an ailing parent. They are contributing care, nurturing, guidance, love and support. A loss of such an individual and their contributions to a family are referred to as pecuniary losses.
