‘McCustody’ dad threatens to subpoena judge in lawsuit

A Manhattan judge wasn’t lovin’ it Tuesday when an angry man threatened to put her on the witness stand.

David Schorr wants to question Justice Deborah Kaplan, who is overseeing his divorce, as part of a separate lawsuit he has filed.

Schorr — who sued a shrink for claiming he was an unfit parent because he had denied his son McDonald’s food — even warned the jurist she better comply.

“You have been ordered to testify in the Court of Claims. The judge will hold you in contempt!” yelled the lawyer-dad in Kaplan’s courtroom Tuesday morning.

But Kaplan shot back that she has not been subpoenaed.

“When I am notified I will appear,” the judge said.

The Upper East Side dad is battling his fashion-exec wife, Bari Yunis Schorr, for custody of their 5-year-old son, Max. He has also sued the state, claiming a court officer attacked him during a confrontation in judge’s chambers last October.

Schorr, whose court-attack suit is separate from the McDonald’s case, wants unspecified damages.

When Schorr asked Kaplan to recuse herself from his case, she told him to stop suing people and ­“focus on what’s best for your son.”
