Most relationships accumulate injury over time. These are not only major ruptures, but also smaller moments that were never properly addressed. Differences and disagreements that did not resolve in a way that allowed both partners to move forward. Actions and inactions that left one person feeling unsafe, unheard, controlled, or not good enough. Each of these moments leaves a trace. Over time, they build up and remain active within the relationship as an underlying level of intensity. They do not disappear. They remain present in the background and continue to shape how partners perceive and experience each other. I refer to this accumulation as the legacy of injury (Korkie, 2025).

As this accumulation grows, the interaction itself begins to change. Each difficult moment is no longer encountered on its own. It is shaped by what has already happened. The present becomes saturated with the past. Reactions become stronger, quicker, and less specific to what is actually taking place. What is being responded to is no longer only the current interaction, but the weight of what has not been resolved.

In most relationships, these injuries are not repaired. They are talked about, argued over, and revisited repeatedly, but something essential does not occur. There is no clear acknowledgement that my action led to a painful experience for you. Instead, the interaction shifts into justification, blame, or positioning oneself as the one who was more affected. Most commonly, it becomes a competition over whose experience is more right, more valid, or more justified.

At a certain point, conversation can no longer carry this material. Not because it is not important, but because the structure of the conversation is part of the problem. The same interaction that created the injury is used to try to resolve it. As intensity rises, the pattern takes over. One speaks, the other reacts. Polarisation develops quickly. Ownership becomes entangled with defence. Impact is diluted by explanation. The interaction shifts away from recognition and toward being right.

At that point, a different structure is required. Repairing the legacy of injury is a deliberate intervention with a clearly defined structure for acknowledging what has happened in the relationship. This prevents the recurring circling back to the past and allows the acknowledgement to land.

It starts with clear guidance during the session.

Each partner writes a letter. Not an apology, not an explanation, and not a promise. An acknowledgement. A clear account of what I did, or failed to do, and how that may have impacted you. Nothing else is included.

The focus is deliberately narrow. It remains on my actions and their impact on you. There is no context, no justification, no balancing of the ledger. The wider relational context is real, but it is not included here. This is not about explaining why something happened or placing it within a broader narrative. It is about recognising that it happened and that it had an effect.

The letters are not exchanged beforehand. They are shared with me individually and reviewed to ensure they remain clean. This means a clear description of actions or inactions and a clear acknowledgement of their emotional impact, without drift into explanation or defence. Only once that is established are they brought into the session.

They are then read out loud, one at a time. One person speaks, and the other listens. There is no interruption, no correction, and no discussion while the letter is being read. The structure is contained and deliberate. It prevents the interaction from reverting to its usual form.

For many couples, this is the first time their historic experience is acknowledged without qualification. Without hooks. Without a “yes, but.” Without the need to defend or counter. Something that has often been carried for years is named directly and without distortion. It creates an experience that is structurally different from what has come before.

This is not a standalone intervention, and it does not resolve everything that has accumulated. It sits within a broader process of changing how conversations unfold in real time and building the capacity to repair interactions as they occur. One of the central tasks of couple therapy is to establish clear acknowledgement of injury and to develop the capacity for ongoing repair, so that the relationship is no longer constantly shaped by what has been left unresolved.

The letters do not erase what has happened, and this is not a once-off process. Work with the legacy of injury typically becomes possible in the mid-stage of therapy, once there has been enough shift in interaction and a reduction in moment-to-moment activation to tolerate both writing and receiving these acknowledgements. At times it may need to happen earlier, but the aim remains the same: to reduce the underlying intensity in the relationship that originates from what has been left unaddressed.

Working on the legacy of injury almost never takes place during the initial sessions, but only once enough softening has occurred, following in-session work as well as the embedding of affirmations, regulation, and corrective actions between sessions. Attempting this work earlier does not hold, as there is simply too much pressure and intensity.

The process of reading the letters is often an observable turning point in the session. It is like a breathing out that occurs when what has been accumulating and causing pain and resentment is acknowledged clearly. This often allows the couple to remain more in the present.
