Beneficiary rights

[Softspeaker]

How much information is a residual beneficiary entitled to? As one executor of my father's estate (my brother is the other) I understand the beneficiaries are entitled to be informed and consulted about the progress of sorting the estate.
We're selling the house and have used a local agent, provided their written explanation of the market price, along with their advice on which offer to accept. At each stage, one beneficiary has made assertions and asked questions which result from serious misunderstandings of the information he's had. He persists in demanding that we answer his incoherent questions, and refuses to make them any clearer.
We'd like to just ignore him, but he's been sabre-rattling about litigation, so we feel rather cautious.
Any advice?

The residual beneficiary is entitled to the accounts when the estate is settled. As you seem to be providing ongoing status that's better than what he is entitled to. What was he threatening to litigate about?

He's been advised that TOLATA 96 (something to do with trusts of land and appointment of trustees 1996) means he's entitled to accounts information not just when the estate is settled, and to be consulted about the sale of the house while we do this.
He's simply mentioned that he could go to court if he is concerned about how we have dealt with the assets.
