Each contract offers a different level of protection, and the W.W.a.R. offers the least. If a buyer pays another buyer representation contract (BRA) during the retention period, the standard OREA form indicates that the buyer is the responsibility of the original agent for the difference between the commission agreed in the first ARO and the commission agreed in the second if he purchases during the hold period: most of the time, however, the two commissions cancel each other out. Note that brokers sometimes have their own AROs and do not use OREB ARBs, so it is important for a buyer to carefully review these terms before signing. An ARO is a contract, and the terms of it are binding, so it`s important to seek legal advice when issues like this arise. .
