If the wife was the GRANTOR of the Trust she had had to have TRUSTEES designated in the Trust -- while wife was alive, she was in charge of Trust; Now that she has passed on, a Trustee is in charge. Find this document -- REVOCABLE LIVING TRUST -- that the wife created and signed, and you will see who she named as a Trustee. This trustee is now in charge of this Trust -- (s)he must do what is asked of him in this Trust and because he is now in charge he should find out whether he can amend it or dissolve it if he so chooses within the law. See who is named as a Trustee.
My question to you is -- if you are to inherit anything from this Trust, do you pay taxes on all or any portion of it?
