Did you lose something and do you have an insurance for that item? You can easily create an insurance form via iLost.
SEARCH via iLost.co if your lost item has been found.
You can fill in the form and print it. Afterwards you can bring the form to the local council to stamp it. However not every insurance company requires a stamp of the local council. Also not every local council is willing to do so. First verify what’s necessary to do by your insurance company and local council.
