Keystone's Special Asset & Litigation Advisory Division supports attorneys, institutional owners, government entities, family offices, and investors facing unusual assets, disputed values, complex transactions, or high stakes decisions. Our senior professionals handle assignments where specialized knowledge, advanced analysis, and the ability to communicate and defend a conclusion are essential.
Some properties cannot be credibly valued through a conventional appraisal process alone. They require specialized market research, industry knowledge, technical collaboration, and a deeper understanding of the asset's economic characteristics.
