Vt. Stat. tit. 8 § 3867
A fire insurance policy shall not be void by reason of failure to make and deliver a proof of loss to the insurer, until the insurer notifies the insured in writing to make and deliver proof of loss in accordance with the terms of the policy and the insured fails to make and deliver such proof of loss within 30 days from the time of receiving such notice. An omission or defect in such proof of loss shall not render the policy void or constitute a defense to an action thereon, unless the insurer notifies the insured thereof in writing within 10 days after receiving such proof of loss, particularly specifying in such notice all the omissions and defects in such proof of loss and the insured neglects for 30 days after receiving such notice to make and deliver a new proof of loss wherein such omissions and defects are corrected.
