A joint account is a bank account shared by two or more individuals, allowing all account holders to deposit, withdraw, and manage funds together. This type of account is commonly used by couples, family members, or business partners to simplify financial management and facilitate shared expenses. Each account holder typically has equal access and rights to the funds, which can promote transparency and collaboration. However, it's important to note that all account holders are equally responsible for any overdrafts or fees, making communication and trust essential in managing a joint account effectively.
