Common Business Documents We Notarize

The operational documents that come up most often:

  • Operating agreements, member resolutions, and corporate consents
  • Commercial contracts and amendments
  • Vendor packets, certifications, and affidavits of authority
  • Construction lien waivers and contractor affidavits
  • Permit applications and licensing affidavits
  • Real estate documents for commercial transactions

Corporate Signing Authority

When you sign as an officer, member, or trustee, the notary verifies your identity and notes the capacity you are signing in. The capacity itself — whether you actually have authority to bind the entity — is something your counsel or the receiving institution verifies separately. Bring titled documentation if a counterparty requires evidence of authority at the table.

Multi-Party and Multi-Location Signings

Larger transactions often need coordinated logistics:

  • Multiple signers at the same location handled in one appointment
  • Coordinated signings across two or three locations on the same day
  • Witnesses arranged in advance when the document requires them
  • After-hours and weekend scheduling for time-sensitive deals

What to Have Ready

A quick checklist that keeps every business appointment on schedule:

  • Current government-issued photo ID for each signer
  • The document complete but unsigned
  • Any board resolution, secretary's certificate, or capacity attestation the counterparty requested
  • A quiet room with table space appropriate to the package size

For recurring corporate work, we can establish a standing relationship with your operations or legal team so dispatch happens with a single email.
