Queens boro president Katz faces grilling over in vitro pregnancy

Now that her primary battle is over, presumptive Queens Borough President Melinda Katz may face a legal grilling over highly personal details of her alleged love affair and in vitro pregnancy with Guardian Angels Founder Curtis Sliwa.

An attorney for the unofficial crime fighter’s third ex-wife, Mary Sliwa, subpoenaed the former City Councilwoman in a child support case over the summer, The Post has learned.

During a Manhattan Family Court proceeding Monday, Mary Sliwa’s attorney, Paul Siegert, accused his client’s ex of improperly delaying the proceeding until after the primary election.

Siegert wants to question Katz about the circumstances surrounding Sliwa’s sperm donation, why she used frozen sperm if she was allegedly carrying on a secret tryst, her finances, and the circumstances surrounding a 2011 agreement in which Sliwa gave Katz over $11,000 a month in child support.

Katz revealed to The Post in an exclusive interview in 2012 that she had used frozen sperm that Curtis donated upon her request in the 1990s, to have two children through in vitro fertilization, the first in 2008 and the second in 2010. The couple now live together in Forest Hills, Queens with the two boys, Hunter and Carter.

In court yesterday Curtis Sliwa’s attorney Alton Abramowitz accused Siegert of acting unethically by representing Mary Sliwa in the current child support case because he had previously counseled Curtis when he signed an agreement with Katz over his sperm donation in 2008.

“Mrs. Sliwa is attempting to make Melinda Katz a witness in this case,” Abramowitz griped to Magistrate Margaret Morgan.

Mary Sliwa is also suing Curtis and Katz in a second court proceeding, claiming she has indisputable evidence that they had an affair and accusing the duo of siphoning $400,000 of Mary’s marital assets to fund the new family.

The Guardian Angel said in court papers that he had divulged highly confidential information to the former attorney, including fears that his frozen sperm was “tainted” or too old to produce babies with his longtime friend and current live-in girlfriend Katz.

Siegert claims Curtis doesn’t have a breach of attorney-client confidentiality claim because the crime-fighting legend spilled his guts to his wife Mary in a meeting with Siegert.

“There was nothing confidential because he told everything to Mary,” Siegert said in court yesterday.

Siegert represented Mary in her divorce from Curtis, which was finalized in 2012. She’s fighting attempts by her ex to slash child support payments for their disabled son Anthony from $12,000 to $2,500 a month.

Magistrate Morgan will rule in the coming weeks whether Siegert should be tossed from the case because of the alleged conflict of interest.

Katz’s testimony is on hold until that ruling is issued.

reached Monday, Katz’s attorney, Steven Mintz said, “We think it’s inappropriate to comment when the matter has been stayed.”

The parties are due back in court on Oct. 1.
