Check your policy, some insurers can be a bit picky about paying out if the property was left unattended and not properly secured.
Yes, it's definitely wise to check your policy carefully before filing any reports/claims. I'm not advocating fraud, but for obvious reasons insurance companies will always see if they can avoid paying out at all or only making a derisory offer. Lack of adequate security systems and locks, unlocked doors and windows, unattended cash not covered unless it's locked away - there can be all sorts of restrictions that could undo a claim.
