Should I need to respond to letter from tenant injury attorney?

[Joshua Corwin]

Hi everyone, really hoping for some advice from the community here.

I have a tenant that is faking an injury (one of these slipped and fell kind of things) and hired an injury attorney. That attorney sent a demand letter requesting information including my insurance policy details, etc., etc., The letter said I have a legal obligation to respond in 30 days, citing the following statute (627.4137) http://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&URL=0600-0699/0627/Sections/0627.4137.html

Note - I have not been formally served, nor is there a claim that has been filed. 

I called my insurance company - they said they won't respond and it was up to me.
One attorney I spoke with said I do not need to respond, and should not as it would only hurt my case if they decided to pursue a lawsuit
Another attorney I spoke with suggested I had to respond by law

Does anyone
1) Know definitively if I am obligated to respond to the injury attorney?
2) If I do not, do people have opinions of I should?

Thank you for your help.
