I have just bought a house. Am I obliged to take on the insurance of the owner who sold it to me?

You do not have to take over the previous owner’s insurance. Simply inform the vendor that you will take care of the insurance and that he/she can terminate the existing policy. However, don’t forget to contact your insurer as soon as possible to make the necessary arrangements for a cover note as soon as the conveyancing documents are signed before a notary.
