Autism / Autism Spectrum Support Group
Autism is classified as a neurodevelopmental disorder which manifests itself in markedly abnormal social interaction, communication ability, patterns of interests, and patterns of behavior. Although the specific etiology of autism is unknown, many researchers suspect that autism results from genetically mediated vulnerabilities to environmental triggers.
Of course you would have to ask them about your exact situation, but ...
SSI is based partly on your child's disability and partly on family income / resources. So, If getting married changes your family income/resources then your child's eligibility for SSI could change. It's NOT an automatic change based the status of getting or being married, but a possible change based on income / resource changes that sometimes go along with that.
Best wishes!
If you are receiving an additional benefit in your name only, then you probably would lose it, but you should check with Social Security about that. The rules about remarriage have changed in the last couple of years.
Hope that helps... Hugs...
