Joint tenancy is most common among married couples because it helps property owners avoid probate. Without joint tenancy, a spouse would have to wait for their partner's Last Will to go through a legal review process—which can take months or even years.
In order to sell or convey the entire property, all owners must join in the transfer. As tenants in common, the co-owners have the right to sell, gift, or transfer their interest in the property without the other owners' permission.
Joint tenants need not be married or otherwise related, and any sort of property, real or personal, may be held in joint tenancy. Only married couples may hold property as tenants by the entirety in Illinois, and they may use that form of ownership only for homestead property.
Joint Tenancy In Illinois A joint tenancy can be undone by either spouse if they convey any portion of their share to a third party. Neither spouse will need the permission of the other spouse to make this conveyance and revert the property to a tenancy in common.
In Illinois, spouses have the option of owning property by the entirety, which functions like a joint tenancy in that the surviving spouse will immediately take ownership of the property on the death of the other spouse. Illinois recognizes joint tenancy with right of survivorship as a common form of joint ownership.
If you are making the application to sever the joint tenancy without the other owner then you will need to complete a SEV form and provide evidence that the other owner agrees to the severance, for example a written notice signed by the other owner.
One of the rights of a joint tenant in real property is to sever the tenancy by conveyance of his interest, in which event, the grantee becomes a cotenant with the remaining joint tenant, and the chief attribute of joint tenancy, viz, the survivor's right to take to the en- tire interest, is hereby destroyed.
Its most extreme form is the secret severance. If the tenant who severs secretly is the first to die, the heirs or successors produce the severing document and take half of the property. It accrues to them under the tenancy in common that was the result of the severance.
