3.3 Civil-Law Terminology Crosswalk

Key Takeaways

  • The Louisiana exam tests civil-law vocabulary directly; learn each term and its common-law equivalent as a pair
  • Immovables are land and things attached; movables are everything else - the civil-law split parallels real vs. personal property
  • Authentic acts (notary + witnesses) carry self-proving weight; acts under private signature are signed by parties only
  • Prescription (acquisitive and liberative) replaces adverse possession and statutes of limitation
  • Key one-word swaps: cause/consideration, servitude/easement, usufruct/life estate, indivision/tenancy in common, Act of Sale/deed

Roughly a third of state-portion difficulty is vocabulary: the test gives a civil-law term and asks for its meaning or common-law equivalent. This section turns that into rote recall.

Master Crosswalk

Louisiana (Civil Law)Common-Law EquivalentOne-line meaning
Immovable propertyReal propertyLand and things attached
Movable propertyPersonal propertyThings not permanently attached
Act of SaleDeedInstrument transferring ownership
CauseConsiderationReason a party obligates itself
ServitudeEasementRight to use another's land/person's right
UsufructLife estateRight to use + take fruits
Naked ownerRemaindermanOwner awaiting the usufruct's end
IndivisionTenancy in commonCo-ownership without partition
RedhibitionBreach of warrantyHidden-defect rescission/price cut
Lesion beyond moiety(no clean analog)Seller relief for grossly low price
SuccessionProbate estateTransfer of a decedent's estate
Forced heir / legitime(no analog)Reserved share for children
PrescriptionAdverse possession / statute of limitationsAcquiring or losing rights by time

Study method: Drill these as flashcards in both directions - given the Louisiana term, state the equivalent; given the equivalent, state the Louisiana term.

Immovables vs. Movables

The civil law divides things into immovables and movables, paralleling real vs. personal property.

CategoryIncludes
ImmovablesLand (tracts), buildings, standing timber, their integral parts and certain components
MovablesFurniture, vehicles, money, and things that can be moved without injury
Component partsThings so attached they become part of the immovable (analogous to fixtures)

When a movable becomes permanently incorporated into an immovable, it becomes a component part (the civil-law version of a fixture analysis). Conversely, the right to remove certain items can be reserved by agreement.

Authentic Acts vs. Acts Under Private Signature

InstrumentHow executedEffect
Authentic actBefore a notary and two witnesses, signed by allSelf-proving; strong evidence; required form for some transactions
Act under private signatureSigned by the parties (may be later acknowledged)Valid but must be proven if challenged

A document executed as an authentic act proves itself in court without further evidence, which is why the Act of Sale is typically passed this way. An act under private signature can be acknowledged before a notary to gain similar effect.

Prescription - Two Flavors

Common-law "adverse possession" and "statutes of limitation" both map to the single civil-law concept of prescription, but in two forms.

TypeWhat it doesKey periods
Acquisitive prescriptionGains ownership through possession10 years (good faith + just title); 30 years (without title)
Liberative prescriptionExtinguishes a claim by the passage of timeVaries by claim (e.g., redhibition ~1 year from discovery; mineral servitude ~10 years nonuse)

Exam framing: If the question is about gaining title by long possession, that is acquisitive prescription (10/30 years). If it is about a deadline to sue or a right expiring, that is liberative prescription.

How These Show Up in Practice

ScenarioCivil-law lens
Neighbor's fence has encroached for 12 years in good faithPossible acquisitive prescription (10-year, good faith + title)
Buyer finds a hidden defect 8 months after closingRedhibition - act within ~1 year of discovery
Mineral rights sold off, no drilling for 10 yearsMineral servitude prescribes back to landowner
Married couple sells the family homeCommunity property - both spouses must sign
Owner grants neighbor a driveway rightPredial servitude (right of passage)

Bottom line: Treat the state portion as a translation exercise. If you can convert each civil-law term to its common-law meaning instantly, the unfamiliar wording stops being a barrier and most state questions become straightforward applications of concepts you already know from the national material.

High-Frequency Terminology Traps

A handful of pairs cause most missed questions. Lock these in:

TrapThe fix
Confusing lesion (low price, protects seller) with redhibition (hidden defect, protects buyer)Lesion = price; redhibition = defect
Thinking usufruct is ownershipUsufruct is use + fruits; the naked owner holds ownership
Treating a personal servitude like a predial servitudePersonal benefits a person; predial benefits a dominant estate and runs with the land
Assuming cause means a lawsuitCause = the reason for the obligation (like consideration)
Mixing up acquisitive vs liberative prescriptionAcquisitive gains rights; liberative extinguishes them
Forgetting the forced heir age23 or younger (not yet 24), or any age if permanently incapacitated

Putting It Together: A Worked Scenario

A married couple owns their family home, purchased during the marriage. The husband dies, leaving two children, ages 19 and 27, the 27-year-old being permanently disabled. Translate the facts:

  • The home is community property, so the wife already owns an undivided one-half.
  • The husband's half passes by succession; the wife typically takes a usufruct over it while the children are naked owners.
  • Both children are forced heirs - the 19-year-old by age, the 27-year-old by permanent incapacity - so the legitime (1/2, since there are two forced heirs) is reserved for them.
  • To later sell, the usufructuary (wife) and the naked owners (children) must join.

Takeaway: Convert each civil-law label to its plain meaning, identify who must sign, and the transaction logic mirrors the national material - just with Louisiana's vocabulary on top.
