Subcontracting is allowed for fixed-price contracts. The person who subcontracts is responsible for the product being delivered and needs to make the client aware that somebody else is also working on the assignment.
Freelancers can't subcontract their hourly contracts.
You can find more information about subcontracting in article 8.2 of the User Agreement.
