How to Set Boundaries with a Narcissistic Ex During Divorce

If you’re divorcing a narcissist, you’ve probably already figured out that “normal” doesn’t apply to your situation. Every conversation becomes a power struggle, every request becomes a battle, and they thrive on chaos and control.

One of the most powerful tools you have during a high-conflict divorce is setting strong, consistent boundaries and sticking to them.

Here’s how to protect yourself legally, emotionally, and mentally when your ex refuses to play fair.


1. Why Boundaries Matter (Especially with a Narcissist)

Narcissists feed off of attention, control, and emotional reactions. If you don’t set clear boundaries, you become an easy target for manipulation and mental exhaustion.

Boundaries protect your energy, limit unnecessary communication, and reduce opportunities for conflict. They also help establish a record of respectful, consistent behavior, something the court will notice.


2. Common Boundaries to Set During Divorce

Here are some boundaries to consider when divorcing a narcissist:

  • Communication boundaries: “I will only communicate via email or through a court-approved app.”

  • Parenting boundaries: “We will follow the court-ordered schedule. No changes unless agreed in writing.”

  • Emotional boundaries: “I will not respond to name-calling, blame-shifting, or personal attacks.”

  • Time boundaries: “I will not engage in conversations outside of court business or co-parenting logistics.”

  • Physical boundaries: “Do not show up at my home, work, or other personal spaces.”


3. How to Enforce Boundaries (Without Escalating Conflict)

Consistency is key. You’re not trying to change your ex, you’re trying to protect yourself. Here’s how:

  • Stick to written communication. Narcissists love verbal ambiguity. Written messages create a record.

  • Ignore emotional bait. When they try to provoke a reaction, don’t take the bait. Keep it boring and businesslike.

  • Use documentation apps. Tools like OurFamilyWizard, TalkingParents, or even a court-ordered parenting app can help.

  • Loop in your lawyer. If boundaries are violated repeatedly, bring it to your attorney’s attention and document it for court.

4. What to Do When They Ignore Boundaries

A narcissist will test your boundaries, guaranteed. They may guilt-trip you, gaslight you, or accuse you of being “difficult.”

Here’s your playbook:

  • Do not justify. Do not explain. You’re not asking permission to protect your peace.

  • Keep a record. Save all texts, emails, and notes about interactions.

  • Request court intervention if needed. Temporary orders or an Order of Protection may be necessary in extreme cases.

Final Thoughts

You are not overreacting. You are not too sensitive. And you are not obligated to make someone else feel comfortable while they’re actively trying to make you miserable.

Setting boundaries during divorce is not just helpful, it’s essential.

If you’re in the middle of a high-conflict divorce or co-parenting situation and don’t know how to begin protecting yourself, I can help. This is what I do every day.
