Which contract clauses would you always review before joining?

I would review adjustments, late-payment rules, termination, transfer, allocation, delivery, obligations after possession and the document that proves ownership—anything that can change cash flow or exit options.

I would also review what happens if the construction schedule changes, not to assume a problem but to understand what the contract establishes for different situations.

I would take the contract to an independent professional if the amount is significant to my finances. A second review can identify obligations that are easy to overlook.
