Hi, My name is Philip. I am an attorney with over 16 years experience. Hopefully I can help you with your legal question.
I am sorry for this dilemma
Actually, the answer to both questions is yes
Can you legally give honest answers? Yes, absolutely.
Could this person file a lawsuit against you? Yes, they could, although filing a lawsuit and winning a lawsuit are two different things entirely.
Let's back up...Defamation
is defined as a false statement of fact that harms the reputation of the victim.
Alex says to Betty, "Charlie is a pedophile, he was convicted last week of child molestation"
In this case, if Alex's statement was true, there is no defamation
On the other hand, if Alex's statement was false, Charlie could sue to recover for any damage done to his reputation
Now, assume that Alex's statement was true but Charlie wants to sue anyways. Is that possible?
Sure, it is possible. However, under this scenario since Alex's statement is true, it is unlikely that Charlie would win the lawsuit.
What you're describing, if your statement was true, you did not commit defamation. This other person could try and sue you, however, if you can demonstrate the statements you made were accurate? The court would not awarded a judgment to the other party. And frankly, they will be wasting their time trying to sue you.
Please let me know if you have more questions. I am happy to help if I can. Otherwise, please rate the answer so I may get credit for my work.
