formation.handoff

act imperative

Validate a formation draft and generate the prefilled handoff link on corpuslaw.us. Pass EVERYTHING you have collected (people, address, management, EIN answers, state-specific answers — see formation.requirements for the checklist). The response says exactly what is still missing — keep collecting and call again until COMPLETE, then give the user the link: it opens the formation agent with every detail pre-loaded, so they only review, sign in, and pay. Free; does not consume credits.

Input schema

Property	Type	Required	Description
`entityType`	string	yes	Entity type to form.
`state`	string	yes	Two-letter US state code, e.g. 'MS', 'WY', 'DE'.
`proposedName`	string	no	Proposed company name.
`contactEmail`	string	no	Founder contact email.
`naicsCode`	string	no	NAICS industry code, 2–6 digits (use formation.lookup_naics to find it).
`principalOffice`	object	no	Principal office address (street, city, state required for a complete draft).
`management`	string	no	LLC management type.
`parties`	array	no	The people. LLC: at least one 'member' and an 'organizer' (same person may hold both roles — pass two entries). Nonprofit: an 'incorporator' and at least 3 'director' entries (plus officers where the state requires them).
`nonprofit`	object	no	Nonprofit-only fields.
`ein`	object	no	Optional $75 EIN (federal tax ID) add-on, when available — formation.requirements says whether it can currently be sold. Set wanted=true/false once the user decides. NEVER include a Social Security Number anywhere — the founder types it into a secure panel on corpuslaw.us, never in chat.
`stateSpecificAnswers`	object	no	Per-state quirk answers under the EXACT keys shown by formation.requirements (e.g. "would_you_like_to_list_members_managers_on_the_state_record"). Values are strings or booleans.
`referral_code`	string	no	Your referral code from account.status, if you have one. The founder saves 25% of the Corpus service fee and the order is credited to your code. Omit it if you do not have one — an absent or unrecognised code changes nothing about the link.
