WA Builder's Error - Required to Pay Expenses?

[Gina]

Variations are being required to our building plans as a result of our builder's mistake. The builder is asking me to pay for the expenses arising from these required variations. Am I obliged to pay under contract law?

 

[Rod]

At face value the builder should pay for their mistake, however the contract may have a get out clause.

You need to read your contract.
