Louisiana Professional Malpractice Case Value Calculator

A Louisiana professional malpractice case holds a licensed professional accountable for falling below the standard of their profession and causing financial loss. Attorney, accounting, and financial-advisor malpractice are the most common, and expert testimony from someone in the same field is almost always required to establish the breach.

Damages equal the financial loss the professional's error actually caused — what you lost or failed to gain because of it. In legal malpractice, Louisiana typically requires proving the "case within a case": that you would have won the underlying matter but for the attorney's error. Engagement letters, billing records, and the professional's own file are critical evidence.

Louisiana requires a malpractice suit against a lawyer, an accountant or an insurance agent to be filed within 1 year from the act or omission, or within 1 year from when it was or should have been discovered, and in all events within 3 years from the act (Louisiana Revised Statutes 9:5605(A), 9:5604(A), 9:5606(A)). Those periods are peremptive: they may not be renounced, interrupted or suspended, though they do not apply in cases of fraud. The deadline for other professionals was not confirmed here.
