LOS ANGELES -- The sisters of slain restaurateur Monica Beresford-Redman have obtained a court order blocking her TV producer husband from tapping into his wife's assets.

According to the court order granted, obtained by TMZ, Monica's assets "may not be sold, encumbered or transferred without Court order" ... "Specifically, Bruce Beresford-Redman does not have the authority to encumber Monica's interest."

Monica's sisters, Jeane and Carla, filed the petition days after Beresford-Redman was arrested in California.

According to TMZ, they feared Beresford-Redman would use Monica's money to help pay lawyers to defend him on murder charges.

Beresford-Redman, 38, was arrested November 16th by U.S. Marshals at his Rancho Palos Verdes home.

He is being held pending a bail hearing set for November 29.

According to the complaint, Beresford-Redman is charged in Mexico with aggravated homicide in the death of Monica Beresford-Redman.

Beresford-Redman was booked at the federal Metropolitan Detention Center in downtown Los Angeles.

The family of Monica Beresford-Redman released a statement through their attorney Tuesday night.

"After seven months of tremendous agony, the Burgos family is relieved to learn tonight that Bruce Beresford-Redman has been taken into federal custody. However, they know that this is not the end in their quest for justice for their sister Monica and are prepared to pursue this horrific tragedy to the end. The family wishes to thank everyone for their continued support."

Monica Beresford-Redman's naked body was found April 8 in a septic tank at the Moon Palace Hotel in Cancun where she had been staying with her husband and two children.

Investigators say she died some time on April 5th.

An autopsy revealed that the cause of death was asphyxia by suffocation.

The autopsy report also indicated the presence of bruising to the victim's face and a blunt head wound that the examiner stated was related to the time and date of death.

On April 9, 2010, a forensic expert examined the couple's hotel room.

He found stains on a pillar in the room, on the sheets on the bed, and on a railing on the balcony of the room.

The stains tested presumptively positive for the presence of blood.

A police source shared with KTLA that they believe Beresford-Redman strangled his wife inside the hotel room and then dumped her body inside the septic tank, 200-feet away.
