TL;DR
About 1 in 7 Louisiana successions becomes contested. The five most common triggers are: questionable testamentary capacity, suspected undue influence, defective testament formalities, forced-heirship disputes, and executor misconduct. Each has a different prescription period and a different evidentiary burden. Spotting which trigger applies in the first 30 days dramatically improves outcomes for both proponents and opponents of the testament.
Most Louisiana successions are uncontested. The ones that aren’t share a small set of patterns.
Our firm handles a mix of uncontested and contested successions. In our experience, contested matters concentrate around five recurring triggers. Recognizing the pattern early matters because each trigger has its own civil-code basis, its own prescription period, and its own evidentiary burden. This is a triage guide for families and surviving spouses trying to figure out whether they have a problem.
Trigger 1: Questionable testamentary capacity
La. C.C. art. 1477 requires that, to make a donation inter vivos or mortis causa, a person must be able to comprehend generally the nature and consequences of the disposition. The burden is on the person attacking the testament to prove the testator lacked capacity by clear and convincing evidence (art. 1482).
Red flags
- Diagnoses of dementia, Alzheimer’s, or vascular cognitive impairment before the testament date
- Hospitalizations or skilled-nursing admissions in the 90 days before the testament
- Sudden, dramatic changes in distribution scheme
- Disposition to a recent caregiver, romantic partner, or new acquaintance
- Medications that affect cognition (opioids, benzodiazepines, certain chemotherapy regimens)
What we do
We subpoena medical records covering the 12 months around the testament date, obtain the drafting attorney’s file (subject to subpoena and confidentiality limits), and consult a forensic geriatric psychiatrist. Capacity contests almost always settle when the medical record is unambiguous in either direction.
Trigger 2: Undue influence
La. C.C. art. 1479 nullifies a donation procured by influence that so impaired the donor’s free will that the disposition cannot be considered the donor’s own. The standard is clear and convincing evidence, unless the alleged wrongdoer was in a relationship of confidence with the donor at the time, in which case the evidence may be a preponderance.
Red flags
- Beneficiary drove testator to the drafting attorney’s office and waited in the lobby
- Beneficiary selected the attorney or provided estate-planning ideas to the testator
- Isolation of testator from other family members in the months before execution
- Beneficiary took testator’s cell phone or controlled mail
- Testament executed while testator lived in beneficiary’s home
- Atypical distribution favoring caregiver, neighbor, or in-home aide
What we do
We collect bank records (looking for suspicious withdrawals), cell phone records (frequency of contact), and witness accounts of the testator’s stated wishes. Undue-influence cases turn on the texture of daily life, not on a single dramatic event.
Trigger 3: Defective testament formalities
Louisiana courts will set aside a testament that fails the formal requirements of La. C.C. arts. 1574-1580.1. The bar is substantial compliance, not perfection, but some defects are fatal.
The defects we see most often
| Form | Common defect | Typical outcome |
|---|---|---|
| Olographic | Incomplete date (no day) | Testament invalidated |
| Olographic | Typed letterhead or pre-printed elements | Testament invalidated |
| Notarial | Missing attestation clause | Testament invalidated |
| Notarial | Witness who is also a legatee | Legacy void; testament otherwise valid (art. 1582) |
| Notarial | Failure to sign each page | Partial invalidation possible |
| Notarial | Execution before non-Louisiana notary without art. 1577.1 compliance | Testament invalidated |

Concerned a Louisiana succession may be contested?
We assess the strength of capacity, undue-influence, formality, and breach claims. Early triage saves families tens of thousands.
Trigger 4: Forced-heirship disputes
A child who qualifies as a forced heir under La. C.C. art. 1493 is entitled to the legitime portion (1/4 of the estate if there is one, 1/2 if there are two or more). The forced heir cannot be deprived of the legitime except for the just causes listed in art. 1621 (e.g., physical violence against the parent, attempted homicide, certain felony convictions).
Two flavors of forced-heirship dispute are common:
- Status disputes: Was the child actually 23 or younger at death? Does the adult child meet the permanent-incapacity standard?
- Reduction actions: Did inter vivos donations or excessive legacies impinge on the legitime, requiring reduction under arts. 1503-1505?
Reduction actions prescribe in five years from the decedent’s death (or two years for accretion). Read our forced heirship deep-dive for the underlying doctrine.
Trigger 5: Executor misconduct or breach of fiduciary duty
La. C.C.P. arts. 3191-3194 impose fiduciary duties on a succession representative: duty of prudent administration, duty to account, duty to preserve property, duty to avoid self-dealing. Beneficiaries can petition for removal under La. C.C.P. art. 3182 on grounds including failure to account, failure to file an inventory, mismanagement, or conflict of interest.
Common executor problems
- Failing to file the descriptive list within the time directed
- Selling estate property to themselves or a relative below market
- Co-mingling estate funds with personal funds
- Refusing to communicate with co-heirs
- Continuing to operate a decedent’s business without court authority
- Paying creditor claims out of order (La. C.C.P. art. 3251 priority)
What we do
We file a petition for accounting and, if warranted, removal. Many cases resolve when the court orders the executor to produce records and the misconduct becomes visible.
The prescription clock
| Action | Prescription | Citation |
|---|---|---|
| Action to annul probated testament | 5 years from probate | La. C.C. art. 3497 |
| Action to reduce excessive donations | 5 years from decedent’s death | La. C.C. art. 3497 |
| Action against executor for waste | Generally 1 year from accounting | La. C.C. art. 3492 (delictual) |
| Action to claim forced heirship status | 5 years from death | Jurisprudential rule |
What to do in the first 30 days
If you suspect any of these triggers applies, take three steps quickly:
- Preserve evidence. Do not destroy or modify any document. Take photos of original instruments. Save email and text exchanges.
- Order medical records. Request a HIPAA release as a potential heir or get them via subpoena once succession opens.
- Get a no-pressure consultation. Triage decisions made early in the case are worth more than later litigation strategy.
Settling without litigation
Most contested Louisiana successions resolve through negotiated family settlement agreements rather than full trial. La. C.C.P. art. 2891 specifically contemplates court approval of compromise. We use mediation routinely, and even mediated settlements that fail often narrow the issues for trial.
