Robyn Gibson Supports Mel in Court

Mel Gibson's soon-to-be ex-wife, Robyn, has written a sworn declaration on behalf of Mel, saying he has never physically abused her or any of their children in the 28 years they were married ... TMZ has learned.

We've learned in the declaration, Robyn writes, "Mel never engaged in any physical abuse of any kind toward me before, during or after our marriage."  Robyn also says there was never any domestic violence perpetrated by Mel against any of their children. 

Yesterday, Robyn was spotted out running errands in Malibu.

We've learned the declaration was filed with the court this morning.  We're told Robyn's declaration will also be submitted to the L.A. County Sheriff's Department when Mel's lawyers present their evidence to deputies next week.
In the 1-page declaration, Robyn acknowledges that she is divorcing Mel but says,  "Mel was a wonderful and loving father."

Robyn -- who is widely respected in Hollywood -- could ultimately be very powerful ammo for Mel.
