document removing name from NYC property deed notarized w/o signer present still valid?

Jan.2014 - while married, my then-husband and I purchased a NYC Manhattan condo - my name on the deed, not on the mortgage. Nov. 2015 - at home in Manhattan, on a Saturday, under duress, I signed a document removing my name from the deed. He had it notarized at his place of employment in Brooklyn days later WITHOUT me present. He was a 'Subscriber'witness -but he 'WAS party to the transaction'. Notary rule states Subscriber witness CANNOT be 'party to the transaction' June 2016 - we are now legally divorced (Uncontested Divorce - husband fraudulently obtain this divorce - witnesses to his coercing me into it as 'on -paper only' to protect marital money from my child support payments to my first husband - undue influence prevented my due diligence - I signed divorce papers 'under duress' with husbands reason 'fraudulent' under the care of 1 Psychologist, 1 Psychiatrist, while on multiple psychiatric prescription medications). Is that document notarized w/o me present valid as he
