Conflict resolution: what is BIFF?

You receive a text from your ex, or your soon-to-be-ex.

It’s accusatory, inflammatory, designed to provoke.

Your heart rate spikes.

Your mind immediately starts composing a response—a detailed, point-by-point rebuttal defending yourself against every unfair characterization.

Stop.

That response you’re mentally drafting? It’s exactly what the other person wants.

It gives them material to twist, reasons to escalate, and evidence that their provocation worked.

You’re about to step into the mud and wrestle with a pig.

There’s a better way. It’s called BIFF.

For people navigating high-conflict relationships—whether with an ex-spouse, a co-parent, or anyone who seems to thrive on creating chaos—it’s one of the most practical tools available.

What Is BIFF?

BIFF is an acronym developed by Bill Eddy, a lawyer, therapist, and mediator who specializes in high-conflict personalities. It stands for:

• Brief
• Informative
• Friendly
• Firm

The concept is deceptively simple: when responding to hostile, provocative, or manipulative communications, keep your response brief, stick to relevant information, maintain a friendly tone, and be firm about any necessary boundaries or positions.

That’s it. No elaborate defenses. No emotional engagement with accusations. No attempts to make the other person understand your perspective or acknowledge their wrongdoing. Just BIFF.

Simple to describe. Harder to execute when you’re angry, hurt, or feeling attacked. But extraordinarily effective when you can pull it off.

Why BIFF Works

Understanding why BIFF works helps motivate the discipline required to use it.

High-conflict individuals feed on engagement. When someone sends you an inflammatory message, they’re often looking for a reaction. Your defensive response, your emotional engagement, your detailed rebuttal—these all provide what they’re seeking. Even negative engagement is engagement. BIFF starves this dynamic by providing minimal fuel.

Extended responses create ammunition. The more you write, the more material exists for misinterpretation, selective quoting, or twisting. A three-paragraph response defending yourself contains multiple sentences that can be taken out of context. A two-sentence BIFF response contains almost nothing to exploit.

Emotional responses escalate conflict. When you respond emotionally—even justifiably so—you typically trigger an emotional response in return. Escalation begets escalation. BIFF breaks this cycle by refusing to match emotional intensity with emotional intensity.

Documentation favors calm, professional communication. If your communications ever become evidence in court proceedings—which happens frequently in custody disputes—a pattern of BIFF responses reflects well on you. You appear reasonable, focused on the children, unwilling to engage in unnecessary conflict. The other party’s inflammatory messages, juxtaposed with your measured responses, tell a story that works in your favor.

Breaking Down Each Element

Let’s examine what each component of BIFF actually means in practice.

Brief

Brief means short. Really short. Shorter than you think necessary.

Your instinct when attacked is to explain, defend, contextualize. You want to address every accusation, correct every mischaracterization, make your reasoning clear. This instinct is understandable but counterproductive.

Brief means:

• One to three sentences for most responses
• No paragraphs of explanation
• No addressing every point raised
• No providing context the other person will ignore anyway

The brevity itself sends a message: “I’m not engaging in this conflict. I’m handling the necessary business and moving on.” It denies the other person the extended engagement they may be seeking.

Instead of: “I can’t believe you’re accusing me of not caring about the kids’ education when I’m the one who has attended every parent-teacher conference while you’ve missed the last three. Furthermore, I was the one who researched tutoring options when Jake started struggling in math, and I’ve consistently prioritized homework time during my parenting time, which is more than can be said for…”

Try: “I’ll pick up the kids at 5 pm as scheduled. Happy to discuss school concerns at our next co-parenting meeting.”

Informative

Informative means sticking to relevant facts and necessary information. It doesn’t mean providing exhaustive detail—it means providing the specific information needed to address whatever legitimate issue exists.

Informative means:

• Answering actual questions with factual responses
• Providing logistical information that’s needed
• Sharing relevant updates about the children
• Ignoring inflammatory content that requires no response

The key distinction: informative responses address what needs to be addressed. They don’t engage with provocations, accusations, or emotional content that serves no practical purpose.

Instead of: “Your email was incredibly hurtful and unfair. I’ve never said anything negative about you to the children, and I resent the implication. The fact that you would even suggest…”

Try: “The kids’ dentist appointment is Tuesday at 3 pm. Let me know if you’d like the address.”

Friendly

Friendly doesn’t mean warm, affectionate, or pretending everything is fine. It means neutral-to-pleasant tone. Professional courtesy. The tone you’d use with a business contact you don’t particularly like but need to work with.

Friendly means:

• No sarcasm
• No passive-aggressive comments
• No hostile language, even when responding to hostility
• Brief pleasantries where appropriate (“Hope you had a good weekend”)

The friendly element is often the hardest when you’re genuinely angry. Your ex just accused you of something unfair, and you’re supposed to respond… pleasantly? Yes. Because friendly tone deescalates, while matching their hostility escalates. Because friendly responses look better if they’re ever reviewed by a judge. Because refusing to engage hostilely denies them the satisfaction of getting under your skin.

Instead of: “That’s rich coming from you, considering your own parenting lately has been…”

Try: “Thanks for letting me know about the schedule change. I’ll adjust accordingly.”

Firm

Firm means clear and definitive about whatever needs to be established. No waffling, no excessive hedging, no inviting further debate on settled matters.

Firm means:

• Clear statements of position when position statements are needed
• Not leaving openings for continued argument
• Not apologizing for boundaries or reasonable decisions
• Ending the communication rather than leaving threads to pull

Firm prevents the endless back-and-forth that high-conflict individuals often seek. Your response addresses what needs addressing and closes the loop. It doesn’t invite continued discussion of matters that don’t require discussion.

Instead of: “Well, I guess I could maybe consider adjusting the schedule, although I’m not sure that really works for me, and I’d have to think about it more, but maybe we could talk about it…”

Try: “That date doesn’t work for my schedule. I’m available the following weekend if you’d like to swap.”

BIFF in Action: Examples

Let’s look at how BIFF transforms typical high-conflict exchanges:

Example 1: Accusatory Message About Parenting

Incoming message: “The kids told me you let them stay up until midnight watching TV. You obviously don’t care about their wellbeing or school performance. This is exactly the kind of irresponsible parenting I’ve been documenting.”

Non-BIFF response: “That’s completely false. They were in bed by 9:30, which is their normal bedtime at my house. I don’t know why they would say that unless you’re putting words in their mouths, which wouldn’t surprise me. And frankly, I’m sick of you ‘documenting’ everything I do like I’m some kind of criminal. Maybe you should focus on your own parenting instead of constantly criticizing mine.”

BIFF response: “The kids were in bed at their usual time. Let me know if you have questions about the pickup schedule this week.”

Example 2: Demands for Schedule Changes

Incoming message: “I need you to switch weekends because my family is having a reunion. You owe me for all the times I’ve accommodated your requests. Don’t be difficult about this.”

Non-BIFF response: “I ‘owe you’? Are you serious? I’ve accommodated you way more than you’ve accommodated me. Last month alone I switched three times for your convenience. And I don’t appreciate being called ‘difficult’ when I’m just trying to follow the schedule we agreed to…”

BIFF response: “I’m not able to switch that weekend. Happy to look at alternatives if you want to propose different dates.”

Example 3: Inflammatory Commentary

Incoming message: “The kids came back with dirty clothes again. I shouldn’t have to deal with your inability to do basic laundry. This is neglectful.”

Non-BIFF response: “They played outside before pickup, which is why there was dirt on their clothes. That’s not neglect—it’s called childhood. Maybe if you weren’t so obsessed with finding things to criticize, you could actually enjoy your time with them instead of inspecting them for flaws…”

BIFF response: “They played outside before pickup. See you at the usual time on Sunday.”

Notice what the BIFF responses don’t do: they don’t defend extensively, they don’t engage with accusations, they don’t match hostility with hostility, and they don’t leave openings for continued argument. They address what needs addressing and stop.

When to Use BIFF

BIFF is particularly valuable in these situations:

Co-parenting with a high-conflict ex. When you’ll be communicating with this person for years—until your children are adults—establishing patterns of non-engagement with conflict preserves your sanity and models healthy communication.

Any documented communication. Texts, emails, and messages through co-parenting apps create records. BIFF ensures your contributions to that record reflect well on you.

When you’re emotionally activated. If your first instinct is to fire back angrily, that’s exactly when BIFF is most needed. The discipline of BIFF creates a pause between trigger and response.

When nothing productive can come from engagement. Some arguments can’t be won because the other person isn’t interested in resolution. BIFF acknowledges that reality and stops wasting energy.

The Mindset Behind BIFF

At our firm, our on-staff divorce coach works with clients extensively on BIFF communication—not just the mechanics, but the mindset that makes it possible.

The hardest part of BIFF isn’t understanding what to write. It’s managing the internal experience that makes you want to write something else. When you feel attacked, your nervous system activates. Fight-or-flight kicks in. Your brain wants to defend, counterattack, or establish dominance in the exchange.

BIFF requires recognizing that impulse and choosing differently. It requires accepting that you won’t get the satisfaction of putting the other person in their place. It requires tolerating the discomfort of not having the last word on every accusation.

The coach helps clients develop this capacity through several approaches:

Recognizing the choice point. Between receiving a provocative message and responding to it, there’s a moment of choice. Learning to recognize that moment—and extend it—creates space for intentional response rather than reactive response.

Reframing the goal. If your goal is winning the argument, BIFF feels like losing. If your goal is preserving your peace and protecting your interests, BIFF feels like winning. The coach helps clients clarify what they’re actually trying to achieve.

Processing the emotions separately. The feelings triggered by hostile communication are real and valid. They just don’t belong in your response. The coach provides space to process those feelings so they don’t leak into communications where they’ll cause harm.

Building the habit. BIFF gets easier with practice. Each successful BIFF response builds the neural pathways that make the next one more automatic.

The Long-Term Payoff

Clients who master BIFF communication consistently report significant benefits:

Reduced conflict. When you stop feeding the conflict cycle, it often diminishes. High-conflict individuals may initially escalate when their provocations stop working, but many eventually reduce their efforts when engagement consistently fails to materialize.

Preserved energy. The mental and emotional resources you used to spend crafting defensive responses, ruminating on accusations, and recovering from exchanges become available for better purposes.

Better legal positioning. If disputes ever reach court, your communication record demonstrates reasonableness. You appear focused on the children and unwilling to engage in unnecessary conflict.

Modeling for children. Even when children don’t see your communications directly, they sense the conflict level between their parents. BIFF reduces that ambient tension.

Personal peace. Perhaps most importantly, BIFF protects your inner life from being hijacked by someone else’s hostility. You respond to what requires response and decline invitations to conflict.

Moving Forward

If you’re navigating a high-conflict relationship—with an ex-spouse, a co-parent, or anyone who seems to thrive on creating chaos—BIFF offers a practical framework for protecting yourself while handling necessary communication.

Brief. Informative. Friendly. Firm.

Frequently Asked Questions

What does BIFF stand for in conflict resolution?

BIFF stands for Brief, Informative, Friendly, and Firm—a communication method developed by Bill Eddy for responding to hostile or high-conflict messages. The approach helps you respond to provocations without escalating conflict, providing minimal fuel for further argument while addressing whatever actually needs to be addressed.

Does using BIFF mean I can never defend myself?

No, but it means being strategic about when and how you defend yourself. BIFF responses can include factual corrections when necessary, but they don’t engage in extended defensive arguments that provide ammunition for further conflict. The goal is addressing what needs addressing without taking the bait of inflammatory content.

How does a divorce coach help with BIFF communication?

The divorce coach helps clients develop the mindset that makes BIFF possible—recognizing the choice point between receiving a provocation and responding, reframing goals from winning arguments to preserving peace, and processing emotions separately so they don’t leak into communications. The mechanics of BIFF are simple; the coach helps with the internal work that enables consistent execution.

Will BIFF responses make the other person stop being hostile?

Not necessarily—you can’t control another person’s behavior. However, BIFF often reduces conflict over time because high-conflict individuals get less satisfaction when their provocations don’t generate engagement. Even when the other person’s behavior doesn’t change, BIFF protects your energy, your legal position, and your peace of mind.

How do I handle the urge to respond defensively instead of using BIFF?

Give yourself time before responding—the 24-hour rule suggests waiting a full day before replying to provocative messages. Write your defensive response if needed, then delete it and write a BIFF response instead. Process the emotions separately through journaling, talking to a friend or therapist, or working with a divorce coach. The goal is acknowledging your feelings without letting them control your communications.
