Common Questions

Frequently Asked Questions

Belzer Law focuses on civil litigation and appellate matters, including appeals before Colorado courts, business and commercial litigation (breach of contract, partnership disputes, fiduciary duty claims), real estate disputes (boundary, easement, quiet title, partition), and tort claims (defamation, negligence, intentional infliction of emotional distress).
An appellate attorney specializes in challenging or defending court decisions at a higher court level. If you believe a trial court made a legal error, or if a verdict was reached through improper process, an appeal may be appropriate. In Colorado, trial decisions are typically appealed to the Colorado Court of Appeals, or in certain circumstances, directly to the Colorado Supreme Court. Appellate practice is highly specialized — not all litigators handle appeals effectively.
