Many thanks for your patience. If she is trying to threaten you with legal action, it would most likely be for defamation. Many people are keen on suing for defamation without having full appreciation of the law or practicalities in doing so. I will try and clarify the position below.
First of all, certain conditions must be met for the statement to be classified as defamatory. These are:
1. There has to be a defamatory statement - the assessment that is often used to establish this is whether the statement tends to lower the claimant in the estimation of right-thinking members of society generally
2. Its publication has caused or is likely to cause serious harm to the reputation of the claimant – this will vary based on what effect it will have but it really has to be something sufficiently serious
3. The statement has been published by the defendant to a third party
4. The claimant must prove that the words complained of were published about him - this should not be an issue if the claimant is named or clearly identified.
Whilst it may be easy to prove that defamation has taken place, the legal process of pursuing such a claim is often complex and prohibitively expensive. A claim must be made in the High Court and will likely require the help of professional defamation lawyers, so the costs will often be high right from the outset, usually in the thousands. There is also no legal aid available for such claims so the complainant must fund these personally.
You must also consider whether you can potentially defend the claim. For example, this can happen by proving the statement was true or an honest opinion which could have been made based on the available facts.
So in my professional opinion these are just empty and unrealistic threats and the chances of her going to court, paying all the money needed for the claim and being successful are very slim.
Does this answer your query?
