Legal Question in Disability Law in California

I doubt any lawyer wants those rights, nor can any anyone be 'given' parental rights. If you mean you need legal representation in the court proceedings needed to seek Conservatorship or Guardianship over someone unable to care for themselves, then you should be seeking someone in the legal field of "Guardianship / Conservatorship", not disability. If serious about hiring counsel to help you in this, feel free to contact me to discuss the facts, issues, requirements and costs of doing this.
