The guarantor had no idea his name was on the loan – until the lawsuit landed
A borrower forged his father's signature on a $17 million loan – a federal court just hit him with a nearly $29 million judgment.
On April 7, 2026, United States District Judge Rudolph Contreras of the District of Columbia entered a default judgment against Christopher J. Donatelli in the case, Highland Park Mezz Lender LLC v. Donatelli. The court awarded $28,314,156.06 in compensatory damages and $565,764.35 in attorneys' fees and enforcement costs. It also found that Donatelli committed fraud – a finding that, under federal bankruptcy law, would likely prevent the debt from being discharged even if he files for bankruptcy.
The story starts in the summer of 2022. Donatelli was trying to refinance debt on two multi-family complexes in Washington, D.C. He managed and held a significant stake in both borrowing entities, Highland Park West, LLC and Columbia Heights Ventures Parcel 26 Holdings, LLC. The lender, MF1 Capital LLC, was prepared to extend a $17 million loan but raised a red flag: Donatelli's own financials did not provide enough collateral. To get the deal across the line, Donatelli added his father, Louis T. Donatelli, as a guarantor. He submitted his father's financial details – net worth, assets, liabilities – and both men appeared to have signed the guaranty when the loan closed in July 2022. The catch is that Louis never signed a thing.
After closing, the borrowers never made a single payment. Not one. Not to the principal and not to the accrued interest. In January 2024, MF1 Capital assigned its rights in the loan to Highland Park Mezz Lender LLC. The new lender filed suit against both Donatellis in May 2025 to recover what was owed under the guaranty.
That is when the whole thing fell apart. Louis, once served with the complaint, denied any knowledge of the loan. He said he never signed the guaranty and never gave anyone permission to sign for him. He then handed the plaintiff something remarkable – an affidavit signed by Christopher himself, admitting that he had forged his father's signature without his knowledge or consent. The plaintiff investigated, amended its complaint to allege fraud, and agreed to dismiss Louis from the case. Christopher, for his part, never showed up. He was personally served with the amended complaint on July 21, 2025. He did not respond. The court entered a default against him on October 3, 2025.
The numbers tell the rest of the story. The loan carried an initial interest rate of 7.7%, built from a 6.3% spread and a 1.4% Term SOFR rate. When the borrowers went into default, the rate climbed another 5% under the loan's default provisions starting in November 2023. With no payments ever made and interest compounding on top of interest, the balance nearly doubled in under four years. The court found the lender's calculations, supported by detailed affidavits and spreadsheets, to be sufficient and awarded the full amount requested. It did decline to award punitive damages, finding that the plaintiff had not shown malice beyond the fraud itself, and that a judgment approaching $30 million – one that would likely survive bankruptcy – was sufficient to punish and deter.
For mortgage and lending professionals, this case is a sharp reminder of what happens when guarantor verification falls through the cracks. MF1 Capital spotted the collateral problem early and required an additional guarantor. But that guarantor had no economic interest in either borrowing entity, and no one independently confirmed that Louis actually signed the documents or intended to be on the hook for $17 million. Direct contact with guarantors, witnessed signings, and third-party identity verification are not just procedural boxes – they are the kind of safeguards that could have stopped this deal from becoming a $29 million loss.
The case also carries a practical lesson on protecting recovery. The lender specifically asked the court to enter a fraud finding so the judgment would likely be protected from discharge in bankruptcy. The court agreed, and that distinction could make the difference between a paper judgment and an enforceable one for years to come.
