JUST SAY YOU DID IT

This is about simply admitting liability or rather the absence of anyone anywhere admitting liability quickly and early before the issues are joined. It can happen to anyone doing a thoughtless, inadequate, hurtful deed and caught in the glare of the headlights.
So far the predictable human response is to deny, shift responsibility or throw mud up. It is cheaper on your resources, your reputation, your ability to do more in the future and your peace of mind if you cut your losses instead of evading responsibility.

This concerns your law firm because in doing right by your client, there will be some or a lot of liability and a need for some one to accept responsibility. This fact has led to endless litigation in some form or the other.
So in what cases should you simply say 'We did it. We are sorry. We will not do it again. How can we make it right'. This is clearly the only way to address the issue but I can just see the reasons and justifications formulation a revolution of a protest as you read this.

Is this not the essence of solving the problem? Admitting you dropped the ball and moving forward quickly?
If it is any comfort or support to your case, because denial is so common it is a specially studied psychological phenomenon this fact of trying to evade or reduce responsibility for the things your client or even you law firm does.

Keep in mind that while you have your duties to your clients, the bias to avoid liability is already working in your thought process. Scientific fact.
