There are a few details you have not told us. For a quick reply I am going from memory so figures may not be exact.
(1) What do you mean by a top-up? As I understand it then
patients with more than £23,500 pay 100%. Below that
she pays a contribution until she is reduced to £14,500.
(2) The CH may charge more than the 'reasonable amount' that the council think a CH should charge. Are you agreeing with the Council or are you challenging it?
(2) You do not indicate if the amounts to be paid before PoA arrives are trivial or may add up to thousands of pounds. If she had not set up a PoA then why not tell the Council and the CH you are applying for power of attorney which is obviously going to take time and you will settle the account as soon as you are
legally allowed to use her assets? The patient has the debt not you. Nobody can assume you are well off and ask you to use your own assets or
illegally your mother's. Negotiate by letter. People say outrageous things they would not risk putting into print. A reasonable CH would know about the delay in getting a PoA when the patient is not longer competent to manage her affairs. If you vaguely mentioned 'I need to ask my solicitor' they would give up hope of getting money quickly.
(3) You do not say if you signed any papers when asking the CH to accept her. That could overrule everything.
(4) 'Setting up a trust'. A bit unusual. Not obvious how a trust could do anything with her assets that a PoA cannot do. You would need good legal advice. The responsibilities of her executor(s) would need to be clarified relative to those of her Attorney.
It is so difficult coping with these demands when you are suffering from the stress of you mother going into care. That is when you can get exploited. Stick up for yourself and remember your rights.
My mom has gone into a CH. It's a very good place. She's getting mostly LA funding with a small top-up needing to be paid. I've now been sent a standing order form. What's the best way to set up payments? We have not got a PofA or Deputyship set up yet.
Would it be best at present to just set up a standing-order to pay the top-up from my bank account at present then change it to paying from her account or a trust set up for her in the future?
Sorry if this question seems rambling.
