It depends upon your reason for switching agents. The clientâ€™s needs and representation come first. The agents right to be paid for his/her efforts which result in a sale cannot be overlooked.
Agents do not get paid until closing, and they absorb a lot of expenses up front and along the way. Agents also invest much time before a closing happens, and many time investments never result in a sale.
If you have reason to doubt that the agent who showed you the property will fail to represent your interests in the transaction, you do have the right to first and foremost be concerned with the outcome of your transaction. If that is your concern, then I suggest you discuss your concerns with either that agent or his/her broker. Perhaps additional support from another agent in the office will meet all of your needs, provide you great representation and keep the original agent on board. Maybe your concerns would cause the broker to assign another agent in lieu of the first, and the broker would determine a reasonable sharing of the commission between the agents.
If you simply switch agents on your own, the original agent who showed the property may make a claim against the second agent for the commission. Procuring cause is more than simply showing a property, and is established after a complete review of all of the details that lead to a sale. If you have an buyer agency agreement with the first agent, you might find yourself accountable for payment of commissions. Even if you are personally not responsible for payment, do you want to be responsible for your second agent to not get paid if the initial agent successfully claims the commission? Thatâ€™s why it is better to simply be up front with all parties.
I would ask that you be respectful of agents who invest their time and spend a deal of money in the hopes of representing you. By all means, your needs as clients must be well served by your agent. You need not be stuck in a situation with inadequate representation simply because one showed you the property. You will need to rely upon this agents skill, knowledge and availability through the rest of the transaction.
So, the answer to your question depends on who showed the property, under what circumstances and why you want to switch agents. Sellers generally pay the commisison from proceeds at closing.
