Buyers arrive with a deed of assignment and a belief that they own land. They own a contract. Until consent, registration and stamping are complete, what they hold is an equitable interest and a queue number.
Three stages, three clocks
Consent, stamping and registration run sequentially, not in parallel, and each has its own failure modes. A defective survey plan surfaces at stage one; an undervalued consideration surfaces at stage two, usually as a reassessment; a mismatch between the deed parties and the root of title surfaces at stage three, when it is most expensive to fix.
Every week you shave off perfection is a week earlier your financier will release funds. Treat it as a critical path item.
Investigate title before you negotiate price, not after. A charting exercise at the survey office costs a fraction of what a committed-acquisition-under-government-acquisition costs, and it takes days rather than months.
Where the transaction is financed, align the perfection timeline with the drawdown schedule in the facility agreement. Lenders who have seen consent take eleven months will price that risk in — and they are not wrong to.
