Deposit/Payments at settlement.

Hi all,

My parents will be selling me a block of empty land. We already have a contract of sale. I have a deposit which I will pay at settlement to them, and will have a bank assist in financing the rest.

My question is, when it comes to settlement day, what type of document will be required by a conveyancer to show that I paid the deposit? Are there a variety of documents which will be acceptable, is there a standard document? Is it generally just a bank transfer or bank cheque made out to them and me providing a deposit receipt?

Thanks all.
