Normally Societies take Building Fire Insurance. So its always better to check with the society -
  • What cover they have?
  • Is earth quack cover is there with Fire Insurance?
  • If content cover of the flat owner is also covered, what is the amount?

Its always better to take content cover separate, because you have the content list and the coverage like burglary insurance, Earth quack insurance are normally missing in the society coverage, to reduce cost.
