update_offer_package

Update offer package

Update the offer-package form, preparation checks, and selected buyer-owned attachments at the exact package revision, before the offer is signed; a signed offer's packet is sealed, and further files go on its delivery email (create_offer_delivery_draft). Seller identity fields may remain blank and do not block offer preparation or signing; the agreement uses Seller(s) of Record. When disclosures or title documents clearly identify this property's seller, fill only empty seller fields from those original pages, preserve buyer-entered values, and do not infer signatory authority. It takes at most 10 attachments. This can invalidate an older review or signing preparation. It does not generate, confirm, sign, or send an offer.
