Hello and thanks for using Just Answer.
My name is ***** ***** am happy to assist you with your enquiry.
The Probate Registry is permitted to issue the grant of Probate to someone who has been appointed by the Court of Protection to apply for the grant. Therefore, once you have been appointed as Deputy, you can proceed as such.
In the meantime, the funeral directors will appreciate that it takes time for their Bill to be paid, so if you just explain th eposition to them. Most Banks will allow a cheque to be drawn in favour of the funeral directors from any account held by your late father-in-law, before Probate has been issued. You may therefore wish to enquirie about this.
As regards ***** ***** Companies, if you phone them and explain the current position, they will just amend their records, and will be happy for any outstanding invoices to be paid just as soon as you are in a position to do so.
So, you don't need to worry.
I hope this assists you and answers your question.
