In personal injury cases, damage to personal property may be a component of an injured victim’s overall damages. How do you prove this component of your case? In Maryland, it is well-established that an owner of personal property may express an opinion as to the value of that property without qualification as an expert. See Maryland Casualty Co. v. Therm-O-Disc, Inc. 137 F.3d 780,786 (1998). The experienced personal injury trial lawyer should be well-armed with this authority whenever proving his or her client’s total economic damages in a personal injury case. The experienced trial lawyer will not let defense counsel convince the court that an expert is needed to opine as to the value of personal property. Maryland law contains no such requirement.
