Former President Donald Trump is still searching for a way to make the $464 million bond in his New York civil fraud case ahead of the deadline at month's end, after dozens of underwriters have balked at the nine-figure sum, his lawyers reportedly said Monday.

"The amount of the judgment, with interest, exceeds $464 million, and very few bonding companies will consider a bond of anything approaching that magnitude," Trump's lawyers told a New York appeals court, according to CNN.

Trump has approached some 30 underwriters to back the bond, which is due by the end of March. 

But one insurance broker, Gary Giuletti, reportedly signed an affidavit stating that securing a bond in the full amount "is a practical impossibility."

New York Attorney General Letitia James said last month that she would move to seize some of Trump's New York properties if he didn't come up with the sum.

This is a developing story.
