要不是 means if it were not for... or if ... had not .... It often introduces a condition that prevented a bad result.
In this sentence, 要不是合同写得很清楚 means:
If the contract had not been written so clearly...
Compared with 如果不是, 要不是 is usually more conversational and often more emphatic. It commonly appears when the speaker wants to say that something negative would have happened otherwise.
This is because of a tone change rule for 不.
Normally, 不 is fourth tone: bù.
But when it comes before another fourth-tone syllable, it changes to second tone: bú.
So:
- 不 + 是 becomes búshì
- 不 + 放 becomes búfàng
This is a very common pronunciation rule in Mandarin.
