My ex partner has made an application to court for residency of our child.
Prior to this his solicitor communicated that the application would not be made so long as I agreed to a specific demand. The communication had without prejudice written in it. I did not agree to the demand so he made the application.
Now my ex partner has submitted a position statement and alludes to this correspondence citing me as being difficult and unreasonable and casting himself as the reasonable litigant attempting to settle out of court.
Am I right in thinking that because he has mentioned the communication that he has waived his WP privilege?
