I need something like: if address is not confirmated you can't pay

Front controller:

public function step2(Step2Request $request){

        $city = City::firstOrCreate([
            'postal_code' => $request['postal_code'],
            'name' => $request['name'],
            'country_id' => $request['country'],
        ]);

        $delivery = Delivery::firstOrCreate([
            'street' => $request['street'],
            'house_nr' => $request['house_nr'],
            'bus' => $request['bus'],
            'city_id' => $city->id,
        ]);
        $user = Auth::user();
        $user->deliveries()->syncWithoutDetaching($delivery->id);

        session(['delivery_id' => $delivery->id]);

        $myCountry = Country::findOrFail($request['country']);
        session(['shipment' => $myCountry->shipment]);
        $ship_cost = session('shipment');
        return view('checkout', compact('ship_cost'));
    }

    public function checkout(){


        if(Request::isMethod('post')){
            $product_id = Request::get('product_id');
            $product = Product::find($product_id);
            Cart::add(array('id' => $product_id, 'name' => $product->name, 'qty' => 1, 'price' => $product->price));
        }
        $cart = Cart::content();
        //increment
        if (Request::get('product_id') && (Request::get('increment')) == 1) {
            $item = Cart::search(
                function($key, $value) {
                    return $key->id == Request::get('product_id');
                })->first();
            Cart::update($item->rowId, $item->qty + 1);
        }
        if (Request::get('product_id') && (Request::get('decrease')) == 1) {
            $item = Cart::search(function($key, $value) { return $key->id == Request::get('product_id'); })->first();
            Cart::update($item->rowId, $item->qty - 1);

        }

        $myCountry = Country::where('id', 1)->first();
        $ship_cost = '1.00';
        return view('checkout', compact ('cart', 'token','cities', 'cit','countries', 'addresses','myCountry', 'ship_cost'));
    }
