Keep both versions, the certified translation, and the correcting amendment or side letter, each dated. Do not quietly replace the earlier text. A file showing the discrepancy found, discussed and resolved is more credible than one presenting a clean document with no explanation of how it came to differ.
Show the correction trail, not a tidy result
Add the translator’s explanation, correspondence addressing the discrepancy and any instrument actually used to resolve it. Link payments already made to the governing terms and retain the original source-and-path evidence. Check which records and translations the relevant filing stage requires. Resolve material funding gaps before submission instead of assuming that a later supplement will be accepted.
Build the trail as a sequence of dated events rather than a folder of statements. Build a simple table: date, amount, from which account, to which account, purpose, supporting document. Start with the executed franchise agreement and create a reconciliation schedule tied to its actual clauses. Temporary seller support may carry a new price or end at a specified time; include the actual agreement. Ask the seller to correct genuine errors or provide a signed explanation before filing; do not silently rewrite the immigration summary.
