Lake Mary Officer Zach Hudson said Wednesday that investigators had decided the dispute didn't rise to a criminal level.
The dispute last month came just days after Shellie Zimmerman filed divorce papers.
Shellie Zimmerman said in the divorce papers that she had separated from her husband in August, a month after he was acquitted in the 2012 fatal shooting death of unarmed black teen Trayvon Martin.
The dispute took place at a home where the Zimmermans had lived before they were separated. The Lake Mary home is owned by Shellie Zimmerman's parents.
