'Crocodile Dundee' Star Paul Hogan -- Spousal Support Is A Croc o' S**t

"Crocodile Dundee" star Paul Hogan feels his wife should fend for herself post marriage, because he's asking a judge to nix any claim she might make for spousal support.

TMZ broke the story ... Linda filed papers to pull the plug on their 23-year marriage. We're told the split has been amicable ... but how long's that gonna last if she doesn't get her monthly?

Paul is worth an estimated $20 mil, and unless there's a prenup she'll definitely get a chunk of that. But according to legal docs obtained by TMZ -- Paul wants a clean financial break once the divorce is final.
