What “pattern” means here
Colorado treats coercion / coercive control in family and protection-order settings. HB26-1309 addresses expert-witness standards for coercive-control evidence: the forum is asking for a regime, not an incident. The recurrence floor used in analysis is calibrated to the temporal scope of the records, not a fixed 3×3.
Statutes
C.R.S. § 13-14-101
Coercion in the definition of domestic abuse (protection orders).
Colorado HB26-1309 (2026)
Expert-witness standards for coercive control in family court.
Expert standard
Confirm the forum's reliability standard (Daubert, Frye, Sargon, or the local equivalent).
What Carlton Research can speak to
Carlton Research can speak to pattern analysis (coercive control breadth, depth, escalation, entrapment, and more). Research is built to the evidentiary rules of the jurisdiction that will hear it. Carlton Research does not recommend parenting time or custody. Research establishes whether a pattern of coercive control is present. Inquire about specific testimony requests or speaking engagements.
This is the brief that already states the floor is not a universal number. Use it.
