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.
Under tenancy in common, when a tenant in common passes away the shares that belong to the dead owner pass to heirs under the laws of Minnesota inheritance. Unlike with a joint tenancy, the tenants in common do not have a right of survivorship in the shares owned by the deceased.
N Owners have survivorship rights. If one joint-owner dies, that owner's interest in the property passes to the other joint owners. For example if one of two joint owners dies, the survivor becomes the sole owner of the property.
Further tenancy in common allows parties to hold unequal shares of property interest. Joint tenancy requires each co-owner to hold equal shares of property. Further, co-owners must transfer the deed at the same time. In this sense, joint tenancy is rigid compared to tenancy in common.
Joint tenants also own an undivided interest in property. The main difference between joint tenants and tenants-in-common is that, upon the death of a joint tenant, that co-owner's interests are extinguished and the surviving co-owner(s) receive the property.
Joint tenants have equal property ownership, share profits and liabilities, and often have a right of survivorship. Tenants in common can have unequal shares, lack a right of survivorship, and can pass their share to chosen beneficiaries.
In joint tenancy, the deed of trust establishes equal rights for all co-owners and includes a right of survivorship. On the other hand, in tenancy in common, the deed of trust clarifies that each co-owner has separate shares of the property with no right of survivorship.
Tenants in common gives you more protections and you can specify in a deed of trust what you would want to happen in the event of relationship breakdown (eg if one of you has first dibs to buy the other out, or a time limit on doing so etc) which is definitely better to decide now whilst you still like each other!
