Does New York have a right of redemption period after foreclosure auction?

Unfortunately New York State does NOT have a right of redemption period post foreclosure sale. Once the property is sold at the public auction to the highest bidder, the original foreclosed owner has no right to satisfy the entire amount owed the lender.  Unless the prior foreclosed owner has legal and/or equitable defenses to the foreclosure action, once the sale has occurred, the owner will be without a remedy. The only thing the prior owner can do in such case is to retain an attorney to determine if the sale was properly held and conformed to statutory law. If the sale was not proper then there could be grounds to move to set aside the sale.  If the sale is set aside, then the prior owner would have the chance to satisfy the loan.  If, however, the sale was proper, then the prior owner would need to show a defense to the foreclosure action, and if such defense is meritorious, it  may result in the foreclosure sale being vacated and maybe  the action being dismissed.
