Some people are making their own enquiries on personal liability insurance & building insurance. Not just for homes, but for commercial properties too.

Have you got the guarantees in writing?
Is it written in Portuguese and in English?
Are the written guarantees in Portuguese legal?
What do you need the cover for?
1. Are you moving out to live in the CV home permanently?
2. Will you rent it out to family and friends?
3. Do you intend to solely rent it out?

Are you covered for breaks-ins, stolen items, damage to furniture, water leaks, accidents in the home etc.etc?
