Frequently Asked Questions

What does BIFF stand for?

Brief, Informative, Friendly, Firm. It was developed by Bill Eddy at the High Conflict Institute to defuse hostile communication.

Does BIFF mean I have to be nice to a hostile co-parent?

No. Friendly means civil, not warm. The goal is to remove emotional hooks, not to placate.

Can BIFF messages be used in court?

Yes — and they tend to make you look reasonable, which matters when a judge is comparing two communication patterns.
