You should use SplitPane.setResizableWithParent static method.

        SplitPane root = new SplitPane();

        final Pane paneFixed = new StackPane();
        paneFixed.getChildren().add(new Text("fixed"));

        SplitPane.setResizableWithParent(paneFixed, Boolean.FALSE);

        Pane paneFree = new StackPane();
        paneFree.getChildren().add(new Text("free"));

        root.getItems().addAll(paneFree, paneFixed);

        stage.setScene(new Scene(root, 300, 200));
        stage.show();
