In a situation where Kakaiku owns a house and decides to sell it without appointing Opia as his agent, but Opia introduces a third party who eventually buys the house, there are a few factors to consider regarding the rights of both Kakaiku and Opia.

1. Agent-Client Relationship: Opia's Claim for Commission
Opia, as a real estate agent, would typically be entitled to a commission for any successful sale that occurs due to their efforts. However, since Kakaiku did not officially appoint Opia as his agent, this may weaken Opia's claim for commission. In general, a legally recognized agency relationship is required for agents to make a commission claim. Therefore, Opia may need to provide evidence of an agreement or understanding between him and Kakaiku regarding the commission.

2. Introducing a Buyer: Opia's Role
Opia's involvement in introducing a third party buyer could be seen as a significant contribution to the sale transaction. Although Opia may not be able to claim the full commission without a formal agency relationship, both parties could negotiate a fee or compensation as a gesture of appreciation for Opia's involvement in finding the buyer. This agreement should be made between Kakaiku and Opia directly, ensuring both parties are satisfied with the terms.

3. Legal Advice: Kakaiku's Rights and Obligations
To protect his rights and ensure a smooth transaction, Kakaiku should seek legal advice regarding the specifics of his situation and the laws applicable in his jurisdiction. Legal professionals can provide guidance on how to handle the commission claim and ensure that the agreement between Kakaiku and the buyer introduced by Opia is legally binding.

In summary, Opia's claim for commission may be weakened since Kakaiku did not officially appoint Opia as his agent. However, both parties can negotiate a fair compensation for Opia's involvement as an introducer of the buyer. Seeking legal advice is crucial for Kakaiku to protect his rights and understand the best course of action based on applicable laws and regulations.
