Hi Mickyboy
You are what is known as a mixed aged couple, I would advise your wife to seek advice from your local Welfare Rights Organisation, you do not say what components of DLA you receive. I believe that your wife will have to apply for UC, but I do not know all the facts which is why your wife needs to contact her local Welfare Rights Organisation;
advicelocal.uk As to your question about DLA, yes it will continue, you will at some stage when DWP re-starts the process be asked to apply for PIP.
