Meyer on Monday ordered Hunter to answer additional written questions about his money — including investments, his art sales and other financial transactions — after Roberts’ attorney Clinton Lancaster claimed he had so far provided “incomplete answers.”

Lancaster argued Hunter divulged neither who had purchased his art nor the estimated values of the pieces.

But Hunter’s attorneys hit back, saying the first son didn’t know the identities of the buyers as part of a purported arrangement to ensure they were unable to “influence” his father’s administration.

“He will not know. Someone else may know,” one of the attorneys told the judge.

Judge Meyer informed Lancaster that he could “issue a subpoena” to force the gallery to divulge names of buyers and prices of the art, adding: “It’s a little incredible that there is no estimate of valuations.”
