Contracts/Agreements: Signed docs, change orders, payments.
Communications: Emails, texts, calls (screenshots/recordings where legal).
Receipts/Invoices: All payments, materials.
Expert Opinions: Get inspector/engineer reports ($200-500).
Witness Statements: Neighbors, subcontractors.
License Proof: Screenshot from state portal--key for "gathering contractor license proof."
