To resolve these issues effectively, establish clear communication channels from the outset and document all agreements in writing. If a dispute arises, try to resolve it amicably through negotiation. If necessary, consider mediation or arbitration as alternative dispute resolution methods, as these can be less time-consuming and costly than litigation. Always ensure that your contracts include clauses that outline the process for dispute resolution to protect your interests.
