In recent months, the family of the late singer Jenni Rivera has been involved in family and work conflicts regarding the administration of the albums and products of the popular banda music star.

The legacy of the "La Gran Señora," continues to generate millions of dollars one year after the singer's death, but seems difficult to manage for her family.

In the most recent scandal, the journalist in charge of co-writing the "Diva of Banda's" biography has filed a lawsuit against the Rivera family over alleged nonpayment.

According to TMZ, journalist Laura Lucio, co-author of the book "Inquebrantable," said that 95 percent of the book, which was originally titled "Mi Vida Loca," was written by her based on recordings she made of Jenni while she was alive.

The project was paused after the singer's tragic death, but was restarted months later by the Rivera family when the original script was found among the files of Jenni's computer, and published in July 2013 under the name "Inquebrantable".

According to Laura Lucio, the Rivera family published the book, which Lucio says she wrote, without consulting her or paying her. According to the journalist, the singer had reached an agreement in which 40 percent of the sales of the book would belong to Lucio.  However, after Rivera's sudden death, a court will have to decide whether part of the profits will go to Lucio.

A few days after being published last July, "Inquebrantable" became a popular book in the U.S., selling around 9,000 copies in its first week, reported La Opinión.

Lucio's lawsuit claims she's owed a sum of $10 million over the sale of the book she says she co-wrote with Jenni Rivera.
