The BIFF method: replying calmly to a message from your ex

The BIFF method is a way to reply to an angry or accusing message. BIFF stands for Brief, Informative, Friendly and Firm.

You get a message from the other parent. There is a reproach in it about something from the past, or a comment about something that happens when the children are with you. It gets to you and you want to write something back straight away.

The BIFF method helps you not to respond to every reproach and still answer clearly.

You can read more about BIFF below, with an example.

A father sits at the kitchen table with his phone in his hands, taking a moment before he replies

What do the four letters stand for?

  • B - Brief. Keep it short and about one thing. Two or three sentences is often enough.
  • I - Informative. Stick to what is needed about the children and the arrangements.
  • F - Friendly. Stay neutral to friendly, with an ordinary greeting and sign-off.
  • F - Firm. Say what you are going to do and leave it at that. Do not defend yourself and do not give a long explanation, because that gives the other person something to react to again. Stay away from reproaches and sarcasm.

Who came up with the BIFF method?

BIFF was devised by Bill Eddy, an American lawyer and mediator. He co-founded the High Conflict Institute and developed the method for dealing with people who are quick to get into conflict. It is often used after a separation.

An example

Say you get this message:

You are late with Tom’s things again. Typical, you only think about yourself.

A first reaction might be:

I am not late at all. We agreed the bag would be by the front door at 6pm. Typical of you, you never pay attention to what we agree.

With BIFF it becomes:

Hi, Tom’s bag will be ready by the front door at 6pm, as agreed. Best, Mark

It does not matter whether you are right, even though that is sometimes what makes it hard. You would like to point out that the reproach makes no sense. With BIFF you only mention the arrangement and you leave the reproach alone.

When does BIFF help?

BIFF helps with a message that has a question in it and a reproach around it. You answer the question without taking on the reproach.

BIFF is not meant for a real conversation. If you want to discuss something big, such as a move or a new school, it is better to talk it through together, or with a mediator.

If you feel threatened or unsafe, BIFF is not the answer. In the Netherlands, call Veilig Thuis on 0800 2000.

Is BIFF the same as grey rock or yellow rock?

No, but it does resemble yellow rock.

With grey rock you give back as little as possible, so the other person has nothing to react to. That is different from BIFF, because with BIFF you simply answer.

Yellow rock is closer: replying briefly, clearly and in a friendly way, without being cold. That is almost the same as what BIFF says.

The difference is in what they are. Yellow rock is an attitude, namely how you position yourself towards a parent who seeks conflict. BIFF is a recipe for one message: four things to go through before you press send. So you can do yellow rock and write your message using the BIFF method.

How BIFF works in BeNice

BeNice has the Feedback Coach. It reads your message before you send it and works along the lines of the BIFF method. If there is a reproach or sarcasm in the message you have written, you get a suggested improvement in BIFF form. You choose whether to use the suggestion or send your own text after all. Threats, intimidation and pure insults with nothing else in them cannot be sent in BeNice.

On the other side there is the Filter. The Filter protects you from sharp incoming messages. You then read a calm version that keeps the message itself. If you do want to read the original, press and hold the filtered message and open the unfiltered version.

Frequently asked questions about the BIFF method

What does BIFF stand for?

For Brief, Informative, Friendly and Firm.

Does BIFF work if the other parent does not join in?

Yes. You do not need the other parent for it, because it is about how you reply.

Do I always have to keep my answer short?

Not always, but usually. The longer your answer, the more you give the other person to react to.

Can I still send my own message?

In BeNice you can. The Feedback Coach makes a suggestion and you choose. You can read more in the frequently asked questions.
