No joint tenancy in Louisiana, full stop
Louisiana is a civil-law jurisdiction, and it does not recognize joint tenancy with right of survivorship for real property. Co-owners of an immovable hold their interests in indivision under the Louisiana Civil Code, and when one co-owner dies, their undivided interest does not pass to the survivor by survivorship — it passes to the decedent's heirs or legatees through succession, the same as any other asset without a beneficiary designation.
Community property: the survivor's half is already theirs
Louisiana is a community property state, and this changes the starting point for married couples in a specific way: property acquired during the marriage is generally owned in equal, undivided halves by both spouses from the moment it's acquired. When one spouse dies, the surviving spouse doesn't inherit their own half — they already own it. Only the deceased spouse's half of the community property is what actually needs to pass to someone else.
Usufruct: what happens to the deceased spouse's half
If the deceased spouse dies without a will, their descendants inherit that half — but subject to a usufruct in favor of the surviving spouse. A usufruct gives the surviving spouse the right to use the property and derive its profits, to the exclusion of the underlying owners, until the surviving spouse's own death or remarriage. During this period, the descendants are called naked owners — they hold the underlying ownership, but the surviving spouse controls actual use and enjoyment of the property.
Why this still doesn't skip the court
Even with this usufruct arrangement, Louisiana real estate doesn't simply transfer on its own. A succession proceeding, ending in a judgment of possession, is still required to formally recognize the surviving spouse's usufruct and the descendants' naked ownership, and to actually clear title to the deceased spouse's half of the property. Without this proceeding, title remains genuinely unclear — which can complicate a later sale, refinance, or mortgage of the property.
The marital portion, when the surviving spouse is the poorer one
Louisiana has a separate statutory protection called the marital portion. When a spouse dies "rich" in comparison to the surviving spouse, the survivor can claim a marital portion from the succession — one-fourth of the succession in ownership if the deceased died without children, the same fraction in usufruct for life if survived by three or fewer children, or a child's share in that usufruct if survived by more than three children. This is a distinct protection from the intestate community-property usufruct described above, aimed specifically at economic disparity between the spouses.
Forced heirship, layered on top of all of this
Louisiana is the only state in the country with forced heirship rules. Certain descendants — children under 24, or of any age if permanently incapacitated — are forced heirs entitled to a protected portion of the estate, regardless of what a will says. This adds another layer of complexity on top of the community property and usufruct rules, and is a major reason Louisiana succession planning genuinely differs from planning in any other state.
The only real way around all of this
Because Louisiana lacks anything resembling common-law joint tenancy, real estate essentially always requires succession unless it was already transferred during the owner's lifetime. See our guide to why Louisiana has no transfer-on-death deed for the two tools — a living trust or a lifetime donation with reserved usufruct — that genuinely avoid succession.
