My former wife and I separated and divorced a decade ago. At the time we signed consent orders that provided that she receive about two thirds of our assets, but she specifically agreed not to include superannuation and share assets. She had a smaller amount of superannuation than did I, and no shares were in her name. A solicitor has now written and asked me for details of these assets, presumably to consider whether an application should be lodged to vary the consent order that we both signed. My former wife has never alleged duress. Should I reply to the initial solicitor's letter or ignore it, and, if I reply, in what sort of terms should I reply? I have little wish to engage a solicitor.
