Holding title in joint tenancy is incompatible with:

Holding title in joint tenancy means that two or more individuals own the property together with equal rights. One of the most distinctive features of joint tenancy is the right of survivorship, which ensures that when one owner dies, their share of the property automatically passes to the surviving joint tenants, rather than being distributed according to a will or through probate.

When property is held in joint tenancy, it is specifically designed to avoid the probate process for the deceased owner's share. This means that upon the death of one joint tenant, the property does not enter the probate court system, thus streamlining the transfer of rights to the surviving owners.

Therefore, the correct answer is that holding title in joint tenancy is incompatible with probate, as joint tenancy bypasses the need for probate upon the death of a joint tenant. This feature makes joint tenancy an attractive choice for many individuals who want to ensure a seamless transition of property ownership upon death, without the delays and costs associated with probate proceedings.
