Totally agree with you @NewFriendlyLadybird .
Being named Executor in the Will grants permission for the Executor to administer the estate, including putting the house on the market if needed.
The conveyancer acting in the sale, will do their own ID and AML checks to satisfy themselves that the Executor is who they say they are. The conveyancer won't want to get sued so they do have to follow all anti-money laundering rules and regulations.
The legislation used by anti money laundering supervisors revolves around who the supervisor accepts as the 'customer'. This is the actual beneficial owner of the property and therefore cannot be someone who is 'claiming' they will own it after probate is through.
@PissedOffNeighbour22 I think you are misunderstanding that the Executor is an authorised person named in the Will to act in the administration of the Estate of the deceased person. They are not a beneficial owner, nor will they own the property after probate is through. They are merely carrying out the wishes stated in the deceased's Will in the administration of the Estate and distribution to the beneficiaries after probate has been granted.
Not only will the conveyancer do the necessary checks, but the probate office will too. It is perfectly acceptable for the Executor to market the property if it needs to be sold so that the beneficiaries can receive their bequests. The majority of probate properties up for sale are marketed before probate has been granted, but usually marketed after the application to the probate office has been sent.
I am currently the Executor of my mum's estate. Mum died recently and I have just submitted the probate application to the probate office. In the meantime, I have had to obtain three valuations by Estate Agents as the probate office or HMRC may ask for this. The Estate Agents are keen to market the property and would do so as soon as I give them the go ahead.
