Second executor refuses to sell property

[Martyn2]

Things have moved on since my last posts. There has now been an agreed sale of the estate property and the buyer is asking for an exchange of contracts and completion date. The second executor is now on board having activating his Power Reserved notice. However he is refusing to sign any documents relating to the sale until I agree to his claimed expenses. In previous posts there was general agreement on Legal Beagle that his expense claims were not sustainable. I see the sale of the property and his claim for expenses as two separate issues. Am I correct? Can he legally refuse to what amounts to negation of the instructions in the wil, purely on the basis of his claims?
