Contractor Paperwork Red Flags Before a Job Starts

📅 Published: June 20, 2026

This guide is for property teams who are letting contractors start before paperwork is complete. Instead of guessing, use the table, checklist, and visual priority guide below to make one useful move today.

Quick answer:
Watch for expired COIs, missing W-9s, wrong legal names, unsigned agreements, and unclear license status.

Who this helps

Property managers.
Vendor coordinators.
Contractor admins.

Use this quick table

Document	Track this	Why it matters
Red flags	Expired, missing, wrong name, unsigned, unclear license.	Fix before work starts.
COI	Carrier, limits, certificate holder, expiration.	Expired coverage creates risk.
W-9	Legal name, EIN, date received.	Accounting needs clean records.
License	Type, number, expiration, authority.	Some trades require proof.
Agreement	Signed date, scope, renewal notes.	It reduces confusion later.
