My cousin bought a house a while ago that doesn't settle for a few more weeks. His lawyer is saying the stamp is due within one month of it going unconditional (which is now) otherwise it'll begin accruing interest. I'm pretty sure I've taken longer than that before and only paid on settlement. Why would you be liable for a tax on a property you don't even own yet? What if something goes wrong at settlement? Also do lawyers / conveyancers generally ask you to pay directly? I've always paid all the money into their trust and they handle everything for me. This has been the experience I've had with the 3 lawyers I've used before.
