I am the father of a 19 year old disabled daughter (learning disabilities). Her mother has been collecting child support for the past 14 years, but our CA Court Order ends child supoort at age 19. Her mother is now in the porcess of taking me back to court to continue the Adult with Disabilities Child Support. I have just retired at age 63 and I know that my daughter will qualify for SSI benefits under my Social Security. How does Family Law Code determine my child support obligation with regard to the SSI benefits that my ex-wife will be receiving as the payee for our daughters SSI benefits? We have joint legal custory, but my ex-wife has physical custory and I only get visitation time.
