In what circumstances will a court interpret a stipulation in a personal injury case?

In Altman v. Altman, 585 So.2d 1127 (Fla.Dist.Ct.App.1991), the trial court was faced with a stipulation with some unclear language. The appellate court found that "[t]his ambiguity cannot be resolved from the four corners of the stipulation; it can only be resolved by taking extrinsic evidence on the parties' intent when making the stipulation. In the absence of such evidence, it is pure speculation to choose" one side's interpretation over the other's. Id. at 1130.
