A New York appellate court has ruled against a family seeking to recover damages from JMK Building Corp. for a lost promissory note. The court's decision, issued on August 26, 2026, reverses a previous ruling that had granted the plaintiffs a significant sum in damages. This case affects the Knutsen family, who claimed they were owed money from the building corporation after a series of complex financial transactions.
The dispute centers around a promissory note linked to a loan made by John Knutsen, Sr., the owner of JMK Building Corp., to the corporation itself. The ruling highlights the challenges of proving ownership and terms of a lost financial document, which can complicate legal claims for recovery.
The case, titled Knutsen v. JMK Bldg. Corp. (Docket No. 2024-11948), began when the plaintiffs, Linda Knutsen and her siblings, filed a lawsuit against JMK and its president, Kevin Knutsen, in 2018. They sought damages for breach of a promissory note that they claimed was owed to them after the death of their father, John Sr. The plaintiffs argued that the note was a legitimate financial obligation of JMK to their family trust.
According to court documents, in 1998, John Sr. loaned $1,089,455.87 to JMK and received a promissory note in return. His wife, Magny Knutsen, later created a trust that included this loan obligation. After her death in 2000, the trust was supposed to receive repayment of $675,000 from JMK, which was documented in a new promissory note. However, the original note was lost due to a flood at the accountant's office, complicating the plaintiffs' ability to prove their claim.
In 2024, the Supreme Court of Rockland County initially ruled in favor of the plaintiffs, granting them a summary judgment for $450,000 plus interest. However, JMK appealed this decision, leading to the recent ruling from the Appellate Division.
The appellate court found that the plaintiffs did not provide sufficient evidence to prove their ownership of the lost note or the specific terms of the agreement. The court stated, "the plaintiffs failed to eliminate triable issues of fact regarding the terms of the note and whether it remained enforceable against JMK." This lack of clarity ultimately led to the reversal of the earlier ruling.
The judges involved in the decision were Hector D. Lasalle, Helen Voutsinas, Laurence L. Love, and Phillip Hom. They concluded that the plaintiffs did not meet the necessary legal standards to receive a summary judgment, which requires clear proof of ownership and enforceability of the note.
This ruling has significant implications for the Knutsen family as they face challenges in recovering the funds they believe are owed to them. The court's decision emphasizes the importance of maintaining proper documentation for financial agreements, especially when dealing with lost or destroyed documents.
Moving forward, this case may set a precedent for similar disputes involving lost financial instruments. It highlights the complexities involved in proving claims without physical evidence and the need for clear legal documentation in financial transactions.
The ruling also raises questions about how families can protect their financial interests in situations where important documents may be lost or destroyed. It serves as a reminder for individuals and businesses to maintain thorough records and consider legal safeguards to prevent such disputes.
As for the next steps, the plaintiffs have the option to appeal the ruling to a higher court if they believe there are grounds to challenge the decision further. However, details regarding any potential appeal or related cases were not available in the court filing.
