In regards to time to collect the recoverable depreciation the policy states:
"b. We are not liable for payment on a replacement basis until you complete repair, replacement, or restoration of the subject property. You may submit a claim on an actual cash value basis and then, no later than 180 days following settlement on an actual cash value basis (or our offer of such if you decline settlement), make further claim in writing on repair, replacement, or restoration which you have completed at the time you make such claim."
