Sevastianos represented the plaintiff, a landlord of a shopping center in Ladue, Missouri. The client leased commercial space to a corporate tenant in St. Louis County, and had the owners of the business sign personal guarantees securing the financial obligations of the corporate tenant under the lease. The case was tried against two personal guarantors, one of which disputed the amount of the landlord's debt, and the other of which claimed he never signed the particular guarantee. Neither defendant's guarantee was notarized, and both original guarantees had been lost by the plaintiff.
