Gregory Bateson’s reflections on the systemic logic underlying the Twelve Steps have stayed with me over the years (1972). They point to a fundamental shift from individual control to participation in a larger system. This logic has informed the therapeutic agreement I now use as a pre-session intervention. Both partners are required to read and agree to it, along with additional information about the process, before the first appointment is scheduled. This is not administrative. It is the first point of intervention.

At its core, it introduces a shift from unilateral control to systemic responsibility. Change no longer sits with the other person, but with the interaction both are participating in. This repositioning begins before the couple enters the room. It interrupts the expectation that therapy will be about correcting one partner and establishes, from the outset, that the work will be directed at the pattern between them (Watzlawick, Weakland, & Fisch, 1974).

This functions as an initial structuring of the process. It makes explicit what is required at an individual level and establishes the conditions under which the work can proceed. If either partner is not willing to engage with this, the work is unlikely to succeed. Not because they are resistant, but because the interaction remains organised in the same way.

The purpose is not to prevent the relational pattern from emerging in session. It will. The purpose is to alter how each person enters that pattern. The agreement begins to interrupt the usual positions that sustain the interaction, certainty, externalised responsibility, control, and defensive reactivity, and replaces them with positions that allow something different to occur.

What this requires, first, is an interruption of certainty. Each partner arrives with a coherent account of what is happening and why. That certainty stabilises the pattern. The agreement introduces the possibility that, while the experience itself may be valid, the way it has been organised into a fixed understanding of the other and of the relationship may be part of what maintains the problem. This does not invalidate experience. It loosens the conclusions drawn from it.

Alongside this is a relocation of responsibility. Attention shifts away from what the other needs to do differently and towards one’s own actions within the interaction. As long as responsibility remains externally anchored, the pattern cannot change. The focus moves to what I do, what I say, how I respond, and how that contributes to what unfolds between us.

From here, ownership becomes possible. Not as a moral position, but as a functional one. Each partner begins to recognise and name their own contribution to the interaction without immediately justifying, explaining, or redirecting blame. This includes both actions and inactions, what is done and what is avoided. Ownership alters the sequence. It interrupts the automatic movement into defence and counter-accusation.

This creates the conditions for repair. Not as a single act, but as an ongoing process that requires remaining in contact with the other person’s experience without correcting it, defending against it, or withdrawing from it. Repair is not achieved through explanation. It is sustained through the ability to stay with what is uncomfortable long enough for it to be acknowledged and worked through.

For this to hold, each person has to tolerate their own emotional experience. Shame, discomfort, loss of position, loss of certainty. These states often trigger the very behaviours that sustain the pattern, escalation, withdrawal, or collapse into victimhood. The agreement requires that these states are not managed through reaction, but held within the interaction.

At the same time, the way meaning is assigned begins to shift. Interpretation, assumption, and the need to fix the other’s intention are reduced. Space is made for the other person’s experience to exist without immediately being organised into something adversarial. This opens the possibility for curiosity. Questions begin to replace conclusions, not as a technique, but as a movement away from already knowing towards discovering something that is not yet fully understood.

Control is also addressed directly. Attempts to control the conversation, the partner, the process, or the outcome keep the interaction organised within the same pattern. Relinquishing control does not mean passivity. It means stepping out of the need to direct what happens next and allowing the interaction to unfold within a different structure.

That structure is not negotiated. It is part of the work. The agreement requires that both partners accept the direction, constraints, and sequencing of therapy, even when it does not align with what feels right or familiar. This establishes the therapist’s role in shaping the interaction and prevents the session from becoming another version of the problem.

Finally, it introduces a different relationship to time and process. Change is not immediate. It does not come from a single conversation or a moment of insight. It requires repetition, effort, and continuation beyond the session. The agreement positions both partners within that process from the beginning.

Taken together, these are not steps to follow, but positions that alter how each person participates in the interaction. They interrupt the conditions that sustain the pattern and create the conditions under which new responses can begin to emerge.

Providing this frame before the first session changes the work in a fundamental way. Some couples choose not to proceed. This is not what they want or are willing to engage with. That decision is made on the basis of clarity rather than after multiple sessions of misaligned expectation.

For those who do proceed, the starting point is different. Both partners enter with an understanding that the focus is on the relationship rather than on changing one person. The first session no longer needs to establish this from scratch. There are fewer questions about what will happen and less time spent explaining the structure of the work.

Experientially, it creates familiarity with the space before the couple arrives in it. It establishes the therapist’s role as leading the process and positions both partners in relation to that structure.

Systemic therapists have long understood that pre-session engagement is not simply preparation. It is intervention. Here, that intervention begins by altering how each partner enters the interaction, before a single word is spoken in the room.
