lawyer letter is just intimidation and act as deterrent. For $80 a letter plus legal fee can buy yourself a lawyer letter to intimidate your adversary.
Use your lawyer to do the same, intimidate them back. Heard fo counter sue?
The onus is on the person who take you to court to proof his claims and only on the statements he want he want to sue. Stay calm don't be afraid and seek legal help which might surpirse you that your clients (no matter how angry he is) may back off if his own legal fees start to accumulate further. He may not win and have to consider your legal fee if he loss.
Your case might take years for the hearing, and postpone and end up your plaintiff might regret and blamed those that instigate him to take legal action against you. The plantiff must put up a affividit and swear to tell the truth but may backfired if he lied in the affividit.
If they take you to court they might not win and will later regret that they did as it will dig up more can of worms. If he lied under oath that is perjury for him and lawyer loses his practice license if lawyer is aware of the case. Even the court will warn the lawyer not to proceed to safe guard the judicary system.
It will never go to the hearing if their lawyer cannnot defend for his client. Layers are also guarded by law. If there is a prominent office holder involved that is even better and will affect his credential and this is not good for him too.
Seek legal advice and use your lawyer to intimidate them back and this is call back fired. You can bill them your legal fees if they back off. It is in the game of threats, intimidations and harassments if you know how to use the law. And lawyer is good for doing just that.
With due respect to your post above jiakhongleow, I could agree only if there are no kangaroos. Problem is this family other than TS is part of the "establishment" and they take care of one another. This is a hard to break case and requires much thinking. We have seen the kangaroos hopping happily before and they will continue to do so for their own.
