What Shire Explains in Your Agreement
The clauses that decide whether you can walk away — mapped, explained, and flagged for your lawyer where it matters.
Conditions & what they protect
Finance, LIM, builder's report, and title conditions — which ones you have, which are missing, and what each lets you walk away from.
Deadlines & timeframes
Every date that matters: condition deadlines, settlement, and whether the timeframes actually leave room to get a LIM or inspection done.
Deposit & penalty terms
When the deposit is payable, when it's at risk, and the penalty interest that applies if settlement is late.
Alterations & cross-outs
Where the standard form has been modified, deleted, or added to — the changes that shift risk onto you.
Chattels & inclusions
What's actually listed to stay with the property, compared against what you were shown or told.
Vendor warranties & special clauses
Sunset clauses, "as is, where is" terms, and special conditions explained in plain English — flagged for your lawyer's attention.
The Agreement Sets Your Deadlines. Your Documents Decide If They're Realistic.
A LIM condition is only useful if the timeframe is long enough to get a LIM. Shire reads your agreement alongside your LIM, building report, and title — and flags when a deadline, a condition, or a missing protection doesn't line up with reality.

Frequently Asked Questions
What is a sale and purchase agreement?
The legally binding contract between buyer and seller for a property transaction in New Zealand. Most residential sales use the standard Agreement for Sale and Purchase of Real Estate published by The Law Association of New Zealand and REINZ — currently the Eleventh Edition 2022 (4), updated in April 2026 — customised with conditions (finance, LIM, builder's report), dates, deposit terms, chattels, and special clauses. Once signed and unconditional, you're committed.
Do I have to get legal advice before signing?
Surprisingly, no. The agent is required to recommend you seek legal advice and give you the opportunity to get it — but nothing legally requires you to actually do so, and there's no cooling-off period for a standard residential purchase. That gap is exactly why understanding the agreement before you sign matters so much.
Is this legal advice?
No. Shire helps you understand what the agreement says — the conditions, deadlines, and clauses in plain English — so your conversation with your lawyer is sharper. It does not replace legal advice, and you should always have a lawyer review the agreement before you sign or go unconditional.
What does Shire flag in an S&P agreement?
The conditions present (and notably absent), every deadline, deposit and penalty interest terms, modifications to the standard form, the chattels list, sunset clauses, and special conditions — each explained and linked to the clause it came from.
When should I review the agreement?
Before you sign it. Conditions only protect you if their boxes are actually ticked on the front page, and if no dates are written in, the standard form's defaults apply — 10 working days for finance, 15 for the LIM and builder's report. Those defaults aren't always realistic (some councils are currently taking longer than 15 working days to issue LIMs), and a five-minute review before signing beats discovering that after.
How much does it cost?
You get $20 of credits free on signup. After that it's $0.99 per document plus 9c per page — an S&P agreement is typically 10-20 pages, so around $2-$3. Your conveyancing lawyer's fee (typically $1,200-$2,500 for a purchase) covers the legal work; Shire's analysis helps you make that time count.
Can Shire read it alongside my other documents?
Yes. Shire analyses the agreement together with your LIM, building report, and title — so if your agreement has a five-working-day LIM condition and your council is currently taking three weeks to issue LIMs, that mismatch gets flagged.
