She would need to contact Social Security at 1-800-772-1213 . The process could get faster if she completes an Adult Disability Report before her appointment.
Please, tell me about the benefits she could get and at what age?
your widow could get reduced benefits as early as age 60 or full benefits at full retirement age. If she suffers from a disability, she could get the benefits as soon as she turns 50 if the disability started before your death or up to 7 years after your death.
What is the maximum amount my family can get from Social Security?
