Tyler Perry Star Tasha Smith -- Getting the Big D ... And Paying For It

Actress Tasha Smith has jumped from filing a restraining order against her estranged husband ... to slapping him with divorce papers ... and right off the bat it's costing her a bundle of cash.

The "Why Did I Get Married?" star sought the split after she and Keith Douglas filed dueling TROs against each other -- and since she's the bread winner in the family ... the judge is making her pay him $50k in spousal support up front.

We broke the stories ... a judge ordered Smith to stay a bizarre 2 yards away from Douglas -- while they were estranged, but still shacking up in the same house. A week later she filed similar docs to get protection from him.

They'll be back in court next month for the restraining orders. As for the $50k payment -- we're told that's just to hold Douglas over until a permanent support agreement is hammered out in divorce court.

Tyler Perry and his 'WDIGM?' writers should be taking notes.
