Step 3 · the part that causes re-dos

Disclosure & compliance package

A clean offer is more than price. KeySign assembles the full statewide package the listing side expects — and flags exactly what still needs you, the way a good transaction coordinator would.

Lead-paint disclosure (FLD)
Built 1948 — federally required. Needs both buyers' initials on page 6. This is the #1 cause of a driveway re-sign.
Needs you
KeySign pre-loaded this exact form set for Santa Clara County so it was on the phone before you lost signal. Forms auto-update when you're online — never mid-deal.

Pre-flight resolves the flagged lead-paint initials before anyone signs.

Step 4 · before anyone signs

Pre-flight check

KeySign reads the whole packet the way a transaction coordinator would — and catches what causes a redo before the buyer has a pen in hand.

Buyer & property fields all present
Names, vesting, APN, MLS, legal description matched
Price, deposit & down internally consistent
EMD is 3% · down payment matches verified funds
Compensation matches the BRBC
¶3G request (2.5%) equals your buyer-representation agreement — no contradiction
Current statewide form set
C.A.R. RPA · Rev. 12/25 · FinCEN language present · cached on device
Lead-paint initials missing — page 6
Federal FLD needs both buyers' initials. KeySign can make this a required stop in the signing flow.
Identity verification ready
Buyers will confirm by knowledge check + SMS code at signing

Resolve the flagged item to continue.

Step 5 · who's signing

Verify the buyers

Identity is what makes a remote-style signature hold up. KeySign verifies each buyer before they touch the document — no notary, no desk required.

Step 8 · the deal doesn't end at signing

Accepted — escrow is open.

A signature is the start, not the finish. The moment the seller accepts, KeySign opens the file and puts every deadline on a clock so nothing slips.

Every contingency date syncs to your calendar and nudges you the morning before it's due. Missing a deadline is how deals — and commissions — die.

Step 9 · trust is a screen, not fine print

This offer holds up.

Identity verified before signing
Knowledge-based questions + SMS one-time code, matched to each buyer

Step 10 · the driveway problem

One bar. Doesn't matter.

The decisive moment happens where signal is worst — a driveway, a car, a rural lot. KeySign treats offline as the normal case, not a failure.

Connectivity right now
Online

Flip the field-signal switch (top-right of the harness, or below) to see the whole flow keep working with no connection.

Forms are cached. The full county form set lives on the device — they open instantly at 0 bars.
Identity & signing are local. KBA questions are pre-cached; signature capture and sealing need no server round-trip.
Send queues and auto-flushes. Submit with no signal and it goes the instant a bar returns — you never babysit it.

Where do you write offers?

KeySign pre-loads the right statewide and county form set so it's already on your phone before you lose signal.

The honest part.

Most signing apps bury what they can and can't do. Here's the truth, up front, before you rely on it in the field.

What KeySign does on its own: draft, assemble disclosures, error-check, verify identity, sign, seal, and queue — with no connection.
What it verifies: buyer identity via KBA + OTP, form currency, and internal consistency of every field against your agreements.
What it doesn't do: it is not legal advice and doesn't replace your broker's review for non-standard terms.
What it never touches: your contacts or photos. It reads only the deals you create in it.
