Solicitor says we have to have a joint executor bank account

[LavenderFT]

Hello. I wonder if you might be able to help!
There are 4 sibling executors of mum’s will. One executor has a deed of variation, which none of the other executors are allowed to see. We are in the process of getting rid of the solicitor before the house sale (probate was granted ages ago). The solicitor is saying there is not enough money for the legacies in the deed of variation. The executor who arranged it is saying they want the legacies to be paid from the house sale, and not from the money held, but the solicitor is not responding to that.
Also, the solicitor is saying they will not release any money until we have set up a joint executor bank account. Is this right?

Since there appears to be a dispute between the executors I imagine the solicitor is insisting on paying the funds they hold to all the executors jointly so that the solicitor cannot subsequently get dragged into the dispute. The solicitor is entitled to do this and leave the executors to sort it out between themselves.

It does not help that one executor is refusing to share relevant information with the others.

Thank you for your replies. We are no further on unfortunately, except I have found out how much the legacies are. Which brings me onto another question. Since we do not know how much the house will eventually sell for, these legacies could potentially be higher than the overall sale, meaning everyone else gets less.
i find it impossible to believe that this has been done without the consent of the other executors, and that it is indeed lawful.
