When Frank Mandelbaum died, he left his grandchildren a trust worth $180,000. But his will states that unless his gay son Robert marries a woman, Robert’s 16-month-old son Cooper will not receive any of his inheritance.

Mandelbaum died in 2007. His will contains an edict that “none of the trust fund set up for his grandchildren will go to any offspring his son Robert might have if he is not ‘married to the child’s mother within six months of the child’s birth.’”

Robert Mandelbaum is a Manhattan Criminal Court Judge, and is arguing in a court battle that his longtime partner Jonathan O’Donnell is the only “mother” their 16-month-old son, Cooper, knows.

A law guardian appointed to look out for Cooper’s interests states that there are “significant public policy reasons” for ignoring the dictate of Robert’s late father.

“Requiring a gay man to marry a woman…to ensure his child’s bequest is tantamount to expecting him either to live in celibacy, or to engage in extramarital activity with another man, and is therefore contrary to public policy,” writes attorney Anne Bederka in court papers. “There is no doubt that what [Frank Mandelbaum] has sought to do is induce Robert to marry a woman.”

I’ll never understand the lengths some people will go to in order to make their homophobic views known. Jeez.
