What are our beneficiary rights?

My husband's grandmother passed away a little over a month ago and she left behind a living trust. My husband, his two sisters, and his uncle are all beneficiaries of the trust. His uncle is the trustee and we requested a copy of the trust over 2 weeks ago. We have still yet to receive anything. He said the lawyer was sending the paperwork to us, and that was on the 14th of July. I again contacted him on the 22nd of July and he said the lawyer doesn't have the paperwork together to send yet but he would contact him again on the 25th and let us know when the lawyer said he would have it sent out to us. We still have not heard anything back from that. I have tried to email him and have received no response. We did find out that him and his wife have been emptying the house out and we knew nothing of it. We have no clue if my husband has any "beneficiary rights" or if his uncle is the one that makes all the decisions when it comes to the assets of the trust. There are quite a bit of assets and it is getting so complicated. We just don't know what to do, or if there is anything that we can do. His uncle also told us that she left my husband all of his grandfather's medals but have yet to receive them. They live 500 miles away so its not like we can just drive over to their house to get them, so we again don't know what we are supposed to do. Thanks in advance for your advice!!
