Generally speaking, there will be no special cheating clause. You should mainly look at some details about your house, and those just need to be handed over. But the contract signed by each of you is the same, with no family ties. You can go back and look at the contract again, because the contract is valid only if it is signed by both parties, so it is not necessarily handwritten. You can take a closer look at the contract team and propose to cancel the contract where it makes sense.
