I had exactly the same problem with my ex,-husband Tara, and I'm afraid my solicitor couldn't do anything to help me get back my personal belongings (I didn't want the TV or washing machine or anything like that; just my own clothes and effects that he would have absolutely no use for, but some of which were very important to me and of deep emotional value to me). The court ordered him to give me everything I listed and he agreed, but he didn't let me have anything.
I hope your solicitor can do more for you, but please be prepared to lose every key to your past. In the end it will be worth it because you will be able to start again properly without him/her in your life. My very best wishes to you.
