Answer:Woman and the done
Explanation:
The woman.
The woman has a title because they had a joint tenants with her ex-husband.
An inter vivos conveyance by one joint tenant of his undivided interest severs the joint tenancy, so that the transferee takes the interest as a tenant in common and not as a joint tenant. Here, there was an inter vivos conveyance by the man to the son of all of the man's interest in the property held in joint tenancy with the woman. This conveyance destroyed the joint tenancy, so that the son takes his interest in the property as a tenant in common with the woman, rather than as a joint tenant.
