Shauna Sand Files for Restraining Order, Divorce

Shauna Sand was quite the busy lady down at the courthouse this week -- because not only did she file for a divorce from hubby Laurent Homburger ... she filed for a restraining order too!

None of this should come as a surprise after both were arrested after an argument earlier this week. Our sources at the time told us the argument took place after Shauna brought up the D-word to Laurent -- and wouldn't you know it ... the divorce docs were signed and dated on May 12 ... a full week before the incident went down. 

As for the restraining order, Shauna was granted the temporary restraining order on Friday, and she cited the recent fight in her application ... claiming Laurent held her down, screamed obscenities and threatened to killer her.

The protective order says Laurent must stay 100 yards away from Shauna and her children, pending a court hearing on June 9.

In light of getting the restraining order, sources close to Lorenzo Lamas tell TMZ he will no longer go to court this week to seek full custody of the couple's three daughters.
