Can a Tenancy by the entirety has a beneficiary?

No, a tenancy by the entirety cannot have a beneficiary. This form of ownership is exclusively between married couples, where both spouses hold an equal and undivided interest in the property. Upon the death of one spouse, the surviving spouse automatically inherits the deceased spouse's interest, which means there is no need for a beneficiary designation. Any transfer of interest during the owners' lifetimes or upon death typically requires the consent of both spouses.
