Letter of Intent (LOI) Apostille & Authentication

Letter of Intent

Formalize your business intentions globally. A Letter of Intent outlines the preliminary commitment of one party to do business with another. When dealing with international mergers, acquisitions, or high-value joint ventures, your LOI must be officially apostilled to be recognized as a valid legal instrument by foreign legal teams and financial institutions.

At US Apostille, we provide expedited authentication for Letters of Intent from all 50 U.S. States. We ensure your corporate declarations are processed through our Maryland hub in just one business day.

Mandatory: Original Documents & Notarization

Physical Requirement: To secure an Apostille, you MUST mail the original Letter of Intent bearing an original "Wet-Ink" signature and the original seal of a Notary Public to our office.

Digital scans, PDFs, or photocopies are NOT accepted. The Secretary of State requires the physical notary impression on the hard copy to verify the document's authenticity before issuing the Apostille.
