My husband and his brother were left property in a luving trust from their mother. She has passed on 10 years ago. What is best way to deal w/trust

I do not understand why nothing has happened for 10 years.  When someone dies, a living trust becomes permanent, and is like a will except probate is not required for assets in the trust.  The trust document will govern who has the power to do what.  However, it is best to distribute the assets than leave them in trust.
