Mel Gibson's Dad Hutton Gibson -- Officially Divorced ... And She's Got Bank!!!

's 94-year-old father Hutton is officially divorced from his wife -- TMZ has learned -- but don't worry, she'll be just fine ... because she's LOADED.

The divorce was finalized Wednesday -- and according to the court docs, 78-year-old Teddy Joye Hicks has over $640,000 in cash and savings as separate property.  And... she gets to keep the Lincoln Town Car.

Teddy Joye's fortune dwarfs Hutton's, who takes away a paltry $22,595 -- but with a son like Mel who pays his dad's bills, Hutton's still got it made.

The former couple had $22,000 in community property -- which they'll split 50/50.

Oh yeah, they also get to keep their own social security benefits -- score!

Hutton and Teddy were married in 2001 and separated last May. Hutton filed for divorce a month later -- and the split was pretty nasty. As we reported, Mel believed Teddy was trying to cut off Hutton's meds in order to accelerate his death.
