You would be surprised how many people think the law will let them have it both ways. Fortunately for you, Colorado law is pretty clear on the legal treatment of engagement rings.
An engagement ring is generally seen as a conditional gift, meaning it’s given in anticipation of marriage. If you had been the one to call off the wedding for a reason that isn’t your ex’s fault, then sure, you could be sued for failing to give the ring back. But it doesn’t sound like that’s what’s happening here.
Your ex can’t have it both ways. Based on what you’ve described, your ex doesn’t have legal grounds to sue you for duty to return a gift because they’re responsible for breaking off the engagement. Colorado’s “Heart Balm” statutes explicitly abolish causes of action for breach of promise to marry, and while they don’t bar the return of property, your ex’s claim is likely frivolous at best.
Whether you can be sued for the ring and the potential defenses available to you will depend on the specific facts of your case, including the nature of the engagement, the reasons for its termination, and the details of the alleged verbal abuse. I suggest booking a consultation with one of our experienced family law or litigation attorneys to assess your situation fully.
