The purchase and sale agreement, the final closing or settlement statement, the mortgage payoff letter, and the lawyer's or agent's trust account statement together account for deductions. Add title evidence showing how long the property was owned and by whom, plus foreign exchange confirmations and the receiving business account statements. Ask one reviewer to reconcile them line by line before anything is drafted.
Reconcile names, dates and amounts first
Discrepancies are usually clerical rather than sinister: a property held jointly, a maiden name on the title, a deposit split across two transfers, a conversion date that moves the figure. Fix each one with a document rather than a narrative sentence. Where a co-owner received part of the proceeds, show that division.
Translations should be prepared for any record not in English, and originals kept available in case the file is questioned later. Add one reconciliation that closes a gap reviewers notice quickly: account for the time between the closing and the transfer. Money that sat somewhere for months, moved between institutions, was partly spent, or earned interest has a history in that interval, and a file explaining the sale and the arrival while skipping the middle invites exactly the question it was trying to avoid.
Keep statements covering the whole period rather than the month at each end. Hypothetical example: proceeds from a property sale sit in a savings account for seven months before funding a freight brokerage, during which a consolidation moves the balance between two banks, and the two additional statements needed to explain that movement take a day to obtain now and would be considerably harder to explain away later.
