[blparent] blind parent's rights for custody of blind child

[Jasmine]

Hi Everyone,
My name is Virginia and I'm a blind mother in California of a 13 year 
old boy who is also blind and learning disabled. I'm currently going 
through a divorce, and my ex husband and his parent's are trying to 
fight for primary custody of my son. Are there any laws or rights that I 
can show them for disabled parent's? Is there anyone who can help me 
fight for my rights? I've heard that the Nfb fights for custody cases 
like this, so I was wondering if anyone in the Nfb can help me out? I 
already have a lawyer to represent me, but she doesn't specialize in 
disability rights for blind parents rights.
Thanks!
Virginia
