The rotten legal apple doesn’t fall far from the tree in one family of litigators, where the kids of a disgraced Manhattan lawyer jailed for pocketing $5 million of his clients’ money are now allegedly refusing to pay dear ol’ dad’s criminal attorney.

Longtime personal injury litigator Stuart Schlesinger, 77, was sentenced in September to six and a half years in prison for stealing from his clients, taking their legal settlements for himself and spending it on hefty mortgages.

Now his three kids, including two lawyer sons and an architect daughter, won’t pay the man who represented their father in court, according to a lawsuit.

Lauren, Michael and Adam Schlesinger pledged to pay defense attorney Murray Richman’s $36,000 fee within 90 days of the conclusion of the case but the promise was “made with the intent to have Richman take the case and then not pay him for his services,” Richman now charges in a Bronx Supreme Court filing.

Richman’s bill is “unequivocal, unambiguous and represents an unconditional promise by no less than two attorney defendants and their sister,” he said in court papers.

The kids couldn’t be reached.
