Joint tenancy is an agreement between owners that upon death, the owner's assets are passed onto the surviving owner. The owner that assumes the assets will own them outright and upon their death will become part of their estate. This transfer of asset's occurs immediately without delay of costs of probate. Joint tenants are not allowed to leave interests from their joint tenancy in their will, since all asset's related to the joint tenancy agreement will be assumed by the surviving owners.
There are four requirements for classifying an agreement as a joint tenancy:
One of the largest benefits of joint tenancy is the ability to avoid probate court proceedings, since all of the assets are immediately transferred to the surviving owners.
Assets in a joint tenancy are not accessible to the family members of the deceased owner. This could leave surviving children with no claim to the assets. If the deceased owner has a significant debt, a creditor could attempt to regain control of the remaining assets related to the joint tenancy to recoup their costs.
