The estate lawyer's ignoring me and I'm the beneficiary. What should I do?

The administrator of the estate has taken a long time to do anything with the trust. I sent him several e-mails to do something with it or give me an update on it. Eventually he had a lawyer e-mail me and told me to contact them from now on. I've been doing so with no update in the last few months. So it's not like I'm expecting one every week, but this is just way too long. This has been on-going for almost 17 months. I'm afraid of fraud or there being nothing left because of how long it's taken.
