A joint account has two owners. Each owner has half interest in the account. A joint account differs from Tenants in Common, who each have full ownership of the account.
A joint account is an account, usually at a bank or other financial institution, that is owned by
two or more people. Often a husband and wife will have a joint account so that both can write
checks for household expenses, for example.
A joint account is one held by multiple holders. In many situations, joint accounts are held by spouses. However, that is not the only case. Joint account holders can be two or more people.
My best understanding of a joint account is that two people have equal access to the account. For instance, a husband and a wife can deposit and withdrawl money from the account.
A joint account is one where more than one person's name appears as the owner of the account. This could be a savings or checking account set up for a couple.
