1. Estates as tenants in common or estates in community property may be created by conveyance from a married couple to themselves or to themselves and others or from a sole owner to himself or herself and others in the same manner as a joint tenancy may be created.
2. A right of survivorship does not arise when an estate in community property is created in a married couple, as such, unless the instrument creating the estate expressly declares that the married couple take the property as community property with a right of survivorship. This right of survivorship is extinguished whenever either spouse, during the marriage, transfers the spouse’s interest in the community property.
