UC new claim and appointee

Can I start a UC claim for my son and appointee claim at the same time. How do I do the appointee part and get the form. I have supporting letter from Doctor, fit not etc. Do I make the claim, and attend the interview on his behalf with ID, he is unable to deal with f2f, as I said I have medical evidence and support of MP, I understand I have to be appointee and not representative to do so, but seem to be going around in circles about procedure. Also, in guidance Asset publishing DWP say if medical evidence is trustworthy and unequivically point to not being able to manage benefit claim then they do not need to do appointee visit to my son, do you know about this? My son cannot manage to cope with his own claim due to stress and anxiety, receives Pip higher for both but can manage simple financial transactions, but not complicated because of distress. Any help, advice or guidance would be gratefully appreciated. My mother has suddenly and unexpededly dieddied unexpectedly and I feel overwhelmed by the whole procedure

Thank you Gordon, I will probably come back to you a few times. My son is unable to deal with his proposed UC claim due to mental health, he would not be able to go to the office, talk to strangers, cope with online journal requirement would all cause extreme distress, all supported by doctor, he can make simple financial transactions but could not deal with running a house, he lives at home. If I am his appointee would his bank account have to be closed, as I feel this is a shame because with support he can take money out etc which is good for his confidence. Also at which stage do I ask to be appointee, in job centre or when applying for UC online?

I am an appointee for my son and we have a joint bank account in my name and his. It is not sensible to have an account in your son's name only if he cannot manage it as, if the account runs into problems or a transaction needs to be disputed, then he will need to deal with it himself once he is over 16yrs.

This is the problem we ran into. It is fine for parents to manage accounts for under 16's but banks will only speak to the account holder after that age.

The account my son had up until the age of 16 cant even be closed as he hasnt the ability to close it and no one else can.
