He’s a son not even a mother could love.

A former Parking Violations Bureau judge accused of cheating the city out of thousands of dollars stole from his own parents, his mother claims in a lawsuit filed against him.

“This is an unfortunate case where defendant used both his parents’ love as well as his position as their trusted attorney to lure them into trusting him to handle their business affairs, only to swindle them in the end,” Marcia Patricof, 87, says about her son Allan, 56, in the Manhattan civil suit.

She says her son — who was forced to return $8,000 to the city after being accused of billing for hours he never worked in 2006 — handled the $26 million 2012 sale of a Valley Stream, LI, apartment building she owned with her husband, Jules Patricof, who was 89 when he died in 2016.

“Defendant promised that he would act at all times in good faith and in the best interests of his parents, Marcia and Jules,” according to the suit.

Instead, he pocketed a $251,000 loan payoff from the sale that should have gone to his parents, the suit says.

Marcia is suing for the return of the money after recently discovering the alleged scheme.

“Defendant wrongfully and intentionally concealed his receipt of the loan payoff from Marcia and Jules,” the suit says.

She’s also seeking $1 million in punitive damages from her son.

“Mrs. Patricof continues to investigate her son’s conduct and intends to vigorously pursue her rights and remedies as well as those of the estate of her late husband,” her spokesman told The Post.

In May 2016, Jules Patricof sued his son for allegedly stealing $80,000 from his share of the sale of another Valley Stream property.

That suit was settled in October 2016. The terms are not public.

Allan Patricof, who does property-tax litigation for the Brooklyn firm Stark Patch Legal, told The Post he hadn’t been served with the suit and declined to comment further.

More than a decade ago, he was the city’s highest-paid parking judge, raking in $110,472 in 2006.

He denied wrongdoing in the time-card probe.

The city’s Finance Department eventually absolved him in the case, but then reassigned him when the allegations resurfaced in 2009.

The family feud extends into Queens, where the mother and son are battling each other in court over a third property.
