An unbroken chain: auction settlement statements or bills of sale, the deposit into a named account, any loan payouts on the equipment, the transfer to closing, and the closing statement showing the funds applied.
Every hop needs a document
Hypothetical example: a Grand Bay-Westfield contractor sells a skidder, a chipper and two trucks at auction, deposits the proceeds, pays out an equipment loan, moves the remainder to a U.S. account and wires it to closing. Each of those five movements needs its own document, and the amounts must reconcile.
Gaps are what create requests for evidence: a deposit that does not match any settlement statement, or a transfer from an account whose earlier balance is unexplained. Where a loan was discharged from the proceeds, include the payout statement so the shortfall is accounted for. Where a family member contributed, document it as a gift or a loan with a signed instrument rather than letting it appear as an unexplained deposit.
Assemble this chain while the records are current, because auction houses and lenders are slower to produce copies a year later.
