§ 211.21 - Evidence to be submitted by claimant.

(a) All claims must be substantiated by competent evidence. If the claim is for rent or other payment the claimant should furnish evidence as to the value of the property, income from the property if previously rented, or rental value of similar property in the vicinity. If the property is under a formal lease to the Government, the claimant should identify the lease and state the covenants of the lease upon which he predicates his claim. Where the claim is for damage to the property which has been or can be economically repaired the claimant should submit in triplicate an itemized signed statement or estimate of the cost of repairs and copies of itemized receipts, evidencing payment for any expenditures made in relation to the property for which reimbursement is claimed.

(b) In support of claims for damage to crops the claimant should submit a statement showing the number of acres, or other unit measure of crops damaged, the normal yield per unit, the gross amount which would have been realized from normal yield, and an estimate of the further cost of cultivation, harvesting and marketing; if the crops are one which need not be planted each year, the diminution in value of the land beyond the damage to the current year's crop should also be stated. All such statements or estimates should, if possible, be by disinterested competent witnesses, preferably responsible dealers of the type of property damaged.
