You may like to state clearly here:
The NAME of the lawyer.
The IC number of the lawyer (if you can get it)
Upload his photograph here.
The LAW FIRM in which the lawyer is practising.
How much he owes your wife.
How many bounced cheques he has issued. Show uploaded photos of those bounced cheques here.
But if you are just using this forum to let off steam and console yourself but are actually afraid of offending the lawyer and will not do anything about it, then better to forget it.
My intuition tells me that you may be making use of the forum members' messages here - to show to the lawyer as a warning. But that is as far as it goes i.e. no further action will be taken by you against the lawyer. It may be that your wife does not want to risk losing a share-buying client.
