OK HB4342

Evidence of prior domestic violence or abuse by a defendant is admissible in criminal cases involving domestic violence charges and may be considered for any relevant matter

Prosecutors must disclose such evidence to the defendant at least 15 days before trial, including witness statements or testimony summaries, unless the court allows later disclosure for good cause

"Domestic violence or abuse" is defined as controlling, coercive, threatening behavior, violence, or abuse against a person in a specified relationship, including psychological, physical, sexual, economic, or emotional abuse

The new provisions do not limit evidence admissibility under other existing rules or laws
