# Setting an arbitrator

An Arbiter must be assigned on contract creation, otherwise a new Arbiter may be assigned if both the Writer and Holder of the contract agree to a new Arbiter by proposing the same new 'Arbiter Choice' address.

If an Arbiter is not assigned the Writer and Holder can propose a new arbiter. If the addresses that the Writer and Holder propose are identical, then that address becomes the Arbiter.

In the SmartPiggy app, the current Arbiter of any contract may be reviewed by expanding the details and selecting the 'Counterparty Management' tab.
