Common Rejections (And How to Avoid Them)

Unsigned or incorrectly notarized POA

POA must be executed and notarized correctly. Signature, notary commission details, and notarial wording must align.

Using copy when destination requires original

Notary chain gaps

If your document chain needs intermediate authentication before SOS, skipping it can cause downstream rejection.
