WARRENTON, Va. (AP) _ A judge has ordered the widow of Washington Redskins' owner Jack Kent Cooke to undergo a psychological examination and turn over medical records to attorneys for her husband's estate.

The examination and records were requested by the estate to help determine Marlena Ramallo Cooke's state of mind when she signed a premarital agreement.

The estate is trying to prevent Mrs. Cooke from receiving any of Cooke's wealth, estimated at $500 million to $825 million. Estate attorneys say she violated the agreement by failing to live with Cooke, as husband and wife.

Mrs. Cooke contends the agreement is invalid because she was forced her to sign it.

``It is a significant invasion of Mrs. Cooke's privacy,'' Mrs. Cooke's attorney, Lynda Schuler, argued Tuesday before the ruling from Circuit Judge William Shore Robertson.

Cooke, who died in April at age 84, cut his wife out of his will shortly before he died.
