Property that is owned in your sole name forms part of your estate and can be gifted to specific beneficiaries.
How your jointly held assets will be disposed of depends on how they are held (whether as tenants in common or joint tenants).
For tenants in common, each tenant owns a distinct share in the property in their own name. This share can be transferred to a beneficiary upon the passing of one of the tenants (it does not automatically go to the other tenant(s)).
For joint tenants (also known as joint proprietors), if one of the joint owners passes away the other owner automatically inherits the deceased share of the property.
The type of ownership will be stated on the title deed of the property.
