General Litigation and Expert Witness
Independent real estate appraisal and expert witness services for mediation, arbitration, and trial in Northern California.

Valuation for disputed matters
General litigation matters often involve complex valuation questions, disputed facts and competing opinions of value. These assignments require more than technical competency. They require independence, clear communication and defensible reasoning that can be explained to attorneys, judges and opposing experts. Sierra Nevada Appraisal Group provides litigation focused appraisal and expert witness services designed to support resolution through mediation, arbitration or trial.
Litigation Appraisal Services
Litigation appraisal assignments are developed with the understanding that every conclusion may be scrutinized. Each report is prepared using sound appraisal methodology, clearly documented assumptions and transparent reasoning. Analyses are structured so valuation logic can be easily followed by legal professionals, even when the property or market issues are complex.
Expert Witness Support
As an expert witness, Brian provides objective opinions grounded in market evidence rather than advocacy. Testimony focuses on explaining valuation principles, market behavior and analytical conclusions in a clear and professional manner. The goal is to assist the trier of fact by presenting reliable valuation analysis without exaggeration or bias.

General litigation and expert witness services are commonly provided for matters involving:
- Disputed real property value
- Construction defects and diminution in value
- Partition actions and ownership disputes
- Easement and access issues

If your case involves complex valuation questions or requires clear explanation of market evidence, this service is likely a good fit.
