AIUI if you knowingly answer a question untruthfully you could be legally liable for damages.
There are some issues where you risk an obvious claim - eg: failing to disclose flooding, subsidence, rights or way etc. "Don't know" may be a fair answer if you are selling on behalf of someone else, but you would be expected to take reasonable care in providing answers.
A bit like an insurance policy (car, house, travel etc) if you answer dishonestly or with a lack of appropriate care, any claim may be refused.
