thank you. The decisions in this respect amount to decisions in respect of your husbands health and welfare and from what you say, do not presently hold a power of attorney for health and welfare; in addition, as you say, if you are of the view that your husband does not have capacity at this stage, he would not legally be able to grant a power of attorney for health and welfare.
You can apply for Deputyship for finance which is similar to power of attorney but it is granted by the court of protection rather than your husband and is a more involved and costly affair. You can also in principle apply for deputyship for health and welfare but they are comparatively rarely granted as the court prefers to make specific orders rather than grant wide discretion to a deputy for such matters. It is also possible to apply to the court for a specific decision in respect of your husband's care arrangements if this cannot be agreed.
One does not have to go to court over such matters. The mental capacity act allows for decisions to be made on what is known as a best interests basis by appropriate parties, in this case, there would presumably be social services who have legal responsibility for your husband's care needs. In the absence of a power of attorney or decision by the court of protection, social services have a duty to have regard to your wishes but do not have to follow them. I assume you have made plain that your preference would be for care provision to be nearer to you to facilitate greater contact.
Ideally would be able to come to some form of agreement as regards ***** *****'s future welfare with social services. If you remain unsatisfied with arrangements and you are unable to come to an agreement, you can consider an application to the court of protection for an order in relation to your husband's care:
there is an application fee of £365 to make the application and should hearing be necessary to decide the application, there will be a further fee of £485
