Hello, thanks for your question. My name is***** can assist with this.
Yes, you are still going to need to go through probate to be able to sell the property. Deputyships from the Court of Protection (which I believe you are referring to) does not mean you can avoid probate and other forms of power of attorney will lapse on death - so in short, you will still need to take the matter through probate.
Does this answer your question please?
