Paris , France ( CNN ) -- French police raided the Paris home of L'Oreal heiress Liliane Bettencourt on Wednesday , a local prosecutor told CNN . Investigators have been looking into Bettencourt 's finances for weeks after allegations of secret , possibly illegal payments to French politicians , including President Nicolas Sarkozy . The lawyer for Bettencourt , reported to be France 's richest woman , asked the court last month to stop the retrieval of additional information on his client . A decision on his request is due in two weeks . Bettencourt is at the center of several ongoing cases , including the one involving the alleged payments to politicians . Her former bookkeeper , Claire Thibout , told police she received envelopes of cash that were to be given to Sarkozy and French Labor Minister Eric Woerth , who previously worked in the Budget Ministry and was in charge of reforms to France 's retirement system . Thibout said she withdrew the sums of money at the request of Bettencourt 's financial adviser , Patrice de Maistre . Police have questioned de Maistre several times about the allegations , which Sarkozy and Woerth have both denied . The alleged payments came to light in secret recordings , purportedly made by Bettencourt 's butler and revealed this summer , that also refer to a Bettencourt bank account in Switzerland containing 80 million euros ( $ 98.3 million ) which had not been reported on her taxes . At the same time , Bettencourt 's daughter went to court in June accusing a photographer of bilking her mother out of a billion euros . Bettencourt was friends with the photographer , Francois-Marie Banier , and allegedly gave him the money . The daughter , however , claims her mother is not mentally competent to handle her own affairs and took the case to court to recover the funds . Bettencourt has since cut Banier out of her will , her lawyer , Georges Kiejman , told CNN on Wednesday . Banier had been the sole heir to Bettencourt 's fortune , and no one has been added to the will in his place , Agence France-Presse reported , citing Kiejman . CNN 's Sarah Goddard contributed to this report .
