Univision’s planned TV series based on the life of the late Jenni Rivera may have just hit the pause button today because of a breach of contract lawsuit from the singer’s estate.

“In blatant breach of the Agreement and his fiduciary duties, and for his own financial gain, Salgado has made, and continues to make, extensive disclosures to various people and entities regarding the business, financial and personal affairs of the late Ms. Rivera and JRE,” says the jury-seeking complaint filed Monday against Rivera’s former last manager Pete Salgado and various production companies (read it here) for breaking a 2013 NDA agreement he signed. “On information and belief, the improper disclosures first occurred in an unpublished ‘book’ authored by Salgado about Ms. Rivera which was disseminated to Defendants, and continued in connection with a television series being developed and produced to air on Univision.”

Jenni Rivera was one of the most successful regional Mexican musical artists of all time, selling more than 20 million records during her two-decade career. Rivera was killed in a December 2012 Learjet crash in northern Mexico while filming the third season of mun2 docu-reality series I Love Jenni. At the time, the singer had just closed a deal to star in her own ABC sitcom called Jenni.

It should be noted that while often mentioned in the dense, multi-claim suit, Univision is not actually named as a defendant in today’s action. What is mentioned is that Rivera’s estate seeks an injunction to essentially shut down the Spanish-language network series, Su verdadero nombre era Dolores (Her Real Name Was Dolores), plus a payout of various damages “in an amount to be proven at trial” and more. Having said that, Univision had no comment on the lawsuit when contacted by Deadline today.

“Salgado’s unauthorized disclosures have greatly harmed Ms. Rivera’s children, as well as the entity that controls the lion’s share of her assets, plaintiff Jenni Rivera Enterprises, LLC who have the sole right to decide whether and/or how such information about their mother may be revealed,” added the complaint put on the docket in L.A. Superior Court on Monday by attorneys Bert Deixler and Phillip Kelly of L.A. firm Kendall Brill & Kelly LLP.

Publicly announced in mid-May, the Univision series about Rivera from Salgado and Latin World Entertainment Holdings and others was preceded by less than a week by word from the estate that it had its own biopics and more in development. The estate’s May 9-announced slate included TV projects such as a music-based series on the Riveras as a musical dynasty and a film based on the life of the singer. No details were given at the time about whom the Rivera estate was  working with or how far along things were on the said projects.

While arguing over whether the NDA was and is binding or even forged, as Salgado’s reps supposedly alleged, today’s complaint makes one thing pretty clear: Univision was not among the estate’s partners for any of those projects.
