Regarding Golden Visa

I want to come in sponsor of my son who is doctor in Dubai having golden visa.
He want to apply for me of golden visa.
I have my own company in dubai and living with my children as my husband is 84 years old and having health issues and he is living in pakistan. As I heard that if I need to apply golden visa then both parents should apply together. In my case as my husband is having health issues and not living in UAE
So should I need NOC from my husband ?
If yes then can he send me NOC by email or how ?
