BIFF means Brief, Informative, Friendly, Firm—a practical pattern for high-conflict co-parenting messages. Use it when you need a paper trail without a fight.
Not legal advice. Match your orders and counsel. This is communication help only.
What BIFF stands for
- Brief — one topic, short paragraphs, no essays.
- Informative — facts, times, places, what you need.
- Friendly — civil tone (not fake warmth). No sarcasm.
- Firm — clear boundary or ask; don’t invite debate.

FAQ
Is BIFF only for high-conflict co-parenting?
It helps most when conflict is high, but brief, factual messages work in low-conflict homes too.
Should every message be BIFF?
Use it when stakes or conflict are high. Logistics still deserve clarity even when things are fine.
Is this legal advice?
No—communication patterns only. Ask a qualified attorney about orders and enforcement.
