The Notebook writer, whose novels A Walk to Remember and Dear John have also been turned into movies, announced his separation from Catherine in January (15).

They have both now signed their shares in the Trent Acres estate over to the Nicholas Sparks trust, which is run by the writer, according to TMZ.com.

Catherine has bought her own $1.1 million (£687,500) mansion a couple of miles away from the estate.

The former couple has five children.
