TX HB3603

Permits evidence of separate family violence offenses against other victims to be admitted to show the defendant's character and acts performed in conformity with that character, overriding Texas Rules of Evidence 404 and 405

Requires the trial judge to hold a hearing outside the jury's presence and determine that evidence of separate offenses would be sufficient for a jury to find the defendant committed those offenses beyond a reasonable doubt

Mandates the state provide the defendant with at least 30 days' notice before trial of intent to introduce such evidence during the case in chief

Takes effect September 1, 2025, and applies only to criminal proceedings commencing on or after that date
