Which of the following is NOT a common method of resolving landlord-tenant disputes?

Informal casual conversation is not typically regarded as a common method for resolving landlord-tenant disputes in a formal context. While casual discussions can occur between landlords and tenants, they often lack the structure and seriousness necessary to address disputes effectively. This approach may fail to resolve underlying issues or lead to miscommunication, which can exacerbate the disagreement.

In contrast, mediation, arbitration, and legal proceedings are more established and recognized methods for handling disputes between landlords and tenants. Mediation involves a neutral third party who facilitates discussions and helps both parties reach a mutually acceptable solution. Arbitration involves a third party making a binding decision after hearing both sides, which provides a more formal resolution. Legal proceedings can include court actions based on breach of contract or other legal grounds to enforce rights.

Thus, while casual conversations might help in some instances, they are not considered a formal or reliable approach for resolving disputes compared to the more structured methods available.
