We are hopefully close to a conclusion on a long, stressful issue which has involved a litigation solicitor and a property solicitor. Both have gone above and beyond. We will not be doing anything until the ink is dry on everything but after that we would like to send a gesture of appreciation. We will send a letter of praise etc to the boss of each of them but would also like to send a bottle of wine each with a card. Is that OK professionally for them? As in can they accept it?
