I think he was trying to intimidate you.
As I said earlier, funeral expenses is a charge on the estate and of the estate hasn’t paid the expenses, then it is the estate that gets taken to court.
However if one of the executors is being obstructive, and legal costs are involved (unlikely in the Small Claims Court) and beneficiaries are going to be disadvantaged because of thousands and thousands of pounds of legal costs, the court can award costs against the obstructive executors personally.
However any such action would normally be brought by disadvantaged beneficiaries if they feel that the executors had entered into litigation needlessly.
You can always submit your defence that you are not the correct defendant here. You don’t owe money personally, the estate does. However if that succeeded, he would just reissue against the estate.
N244 is for any application within existing proceedings.
From memory, this case is about him paying the funeral with dodgy money or what you suspect is dodgy money and then wanting it back into his bank account which could in effect be money-laundering? Is my recollection correct?
Then, he said he took the money out of the bank but wouldn’t produce proof of that and then at the eleventh hour decided he had not taken the money out of the bank. Is that correct?
If this is dodgy money, I think he is skating on very thin ice.
