The legal action, filed at Los Angeles Superior Court on Friday (27Aug10), is from her ex-representative Marv Dauer, but also includes complaints from The Centurion Group and The Law Offices of Lon B. Isaacson who all claim the Bold and the Beautiful star owes them money.
Dauer claims Tylo has failed to pay him a massive $250,000 (£166,667), according to TMZ.com.
Tylo, 47, and Gersson Archila, 38, exchanged vows at Cupid's Wedding Chapel on 28 November (09).
U.S. tabloid the National Enquirer snapped the new couple during the ceremony, with close friends and family celebrating the union.
The Bold and the Beautiful star hit the headlines in September (09) after splitting with Cofield, who she accused of abusing her children after she discovered he was cheating on her.
Archila is Tylo's third husband. The actress ended her 18-year marriage to actor Michael Tylo in 2005. She was previously married to Tom Moreheart.
The Bold and the Beautiful star claims Shanna Downing, of the Horizon Family Therapy & Wellness centre in Nevada, advised her son, Michael, 19, to stop taking his seizure medication.
The teenager subsequently suffered a fit and drowned in a family pool in October, 2007.
Tylo alleges Downing told her Michael's seizures were "due to the stress he was experiencing due to his parents break-up," and "once the stress was eliminated... his seizures would disappear", according to the wrongful death lawsuit filed in a Las Vegas court on Friday (16Oct09).
The documents also state "the care, advice and treatment rendered... caused (Michael's) seizures to continue and lead to his untimely death."
The legal action is Tylo's second lawsuit against Downing and Horizon Family Therapy & Wellness - in 2008, she tried unsuccessfully to amend a previous lawsuit to include a wrongful death claim.
The former The Bold and the Beautiful star, 47, hit the headlines last year (08) when she obtained a restraining order against Corey Cofield amid allegations he beat her daughter with a belt.
Cofield denied the claims and Tylo had the court order dropped months later after reconciling with the guitarist.
The actress split from Cofield for good in May (09) but is only now revealing the reasons behind her decision to boot him out of her family home.
She tells the National Enquirer, "It was like a bad soap opera. I booted Corey out in May after I found a letter he'd left on my computer - a love letter to his old fiancee. He claimed he couldn't contact her because he'd been out of town, but that he missed her."
Tylo is thankful she didn't marry Cofield, her boyfriend of two years, because he has already caused her so much heartache since the break-up.
She adds: "Corey wanted to get engaged in December but I realised he wasn't a marriage candidate for me. ...He screwed up financial things for me. I found bills weren't paid that I thought he'd paid... Since I kicked him out, he's been leaving me alone."
