As a business the insurance company can ask for whatever they want (within reason) to manage their risk. However asking for a signature before providing the T&Cs is highly questionable. Always read the fine print hefore signing.
As to whether they have “no knowledge of any action in the future” another reason to read the fine print. That is an incredibly vast statement basically capturing every comment even those made at the local pub. How many people here would sign such a document eyes closed?
