What You Will Need to Request a Medallion Signature Guarantee


  • Your Wildfire account number.

  • All owners of the document being guaranteed need to be present and have current government issued identification (e.g., driver’s license) .

  • Completed documents – documents with corrections or that are incomplete cannot be guaranteed. Please do not sign your completed form(s) as this must be done in the presence of the guarantor completing the imprint.

  • Your most recent account statement showing ownership, account number, and value of the security.

  • Your stock certificate, if applicable, due to the guarantor needing to verify the current value of the stock.

  • Your letter of intent and written instructions from the brokerage firm, if applicable. The instructions need to state what must be contained in the letter, who should sign the letter, and that the signatures must be guaranteed.

  • If you are not the owner of the security, but have the authority to sign for the owner, we must have the appropriate proof that you can sign for the owner. This may include Power of Attorney documents, Guardianship or Conservator papers, Trust Agreements, Letter of Authority for a deceased member, and Corporate Resolutions.
