What Documents Should You Keep During a Contract Dispute?
A contract dispute is easier to understand when the promise, performance and alleged loss can be followed in sequence. Start preserving records before accounts disappear or devices are replaced.

Find the agreement that was actually made
Keep the signed contract, schedules, specifications, quotes and incorporated documents. Preserve earlier drafts separately; they may explain negotiation, but they are not necessarily the final terms.
Add written amendments, change orders and messages in which the parties agreed to vary time, price or scope. Label unsigned proposals clearly.
Connect performance to dates
Collect delivery records, time sheets, photographs, inspection reports, notices, support tickets and correspondence about problems or acceptance. Original digital files can contain useful date information.
Prepare a chronology with links to the supporting record. Separate direct observations from statements made by someone else.
Show how the amount is calculated
Keep invoices, payments, refunds, replacement quotes and evidence of steps taken to reduce loss. A damages table should identify each amount, date and source.
Do not destroy unfavourable records. Preservation duties extend to relevant evidence, not only documents that support one position. Confirm limitation periods even while negotiation continues.
