Frequently asked questions about the Business Communication IPA Letter
-
Can an IPA Letter be signed electronically?
Yes. Electronic signatures are generally enforceable under the ESIGN Act (15 U.S.C. ch. 96) and state UETA laws when intent, consent, attribution, and record retention are present.
-
How do I confirm signer authority?
Verify signer title, board resolutions, or internal delegation documents. For organizations, include the signer's title and, when necessary, supporting corporate authority documents.
-
Is notarization required for these letters?
Most business communication letters do not require notarization. If a notary is needed due to transaction type or state rule, follow state notary requirements or use RON where permitted.
-
How long should signed letters be retained?
Retention depends on purpose: financial records at least three years (IRC §6501(a)), HIPAA-related items six years (45 CFR §164.530(j)); consult legal for specifics.
-
Can I amend a letter after signing?
Amendments require agreement from all parties. Create a written amendment stating changes, have all parties execute it, and attach it to the original record.
-
What if the wrong party signs?
If a signatory lacks authority, the document may be voidable. Promptly obtain corrected execution with proper authority and document the corrective steps taken.
