Decoupling is a transfer with real consequences
Changing co-ownership can involve a sale or transfer of an interest, valuation, financing, conveyancing, CPF refunds and stamp duties. It should not be treated as a simple technique for avoiding Additional Buyer's Stamp Duty.
Questions to resolve before any transfer
- Who legally owns each interest before and after the transaction?
- What consideration, valuation, BSD or ABSD may apply?
- How will outstanding loans and new borrowing be assessed?
- What CPF principal and accrued interest must be refunded?
- What are the matrimonial, estate, insolvency and future-sale consequences?
