La. Stat. tit. 51 § 3145
A home service contract shall require every provider to permit the service contract holder to return the home service contract within twenty days of the date the home service contract was mailed to the service contract holder or within ten days of delivery if the home service contract is delivered to the service contract holder at the time of sale or within a longer time period permitted under the home service contract. Upon return of the home service contract to the provider within the applicable time period, if no claim has been made under the home service contract prior to its return to the provider, the home service contract is void and the provider shall refund to the service contract holder, or credit the account of the service contract holder, with the full purchase price of the home service contract. The right to void the home service contract provided is not transferable and shall apply only to the original service contract holder and only if no claim has been made prior to its return to the provider. A ten percent penalty per month shall be added to a refund that is not paid or credited within forty-five days after return of the home service contract to the provider.
