Normally a person or persons has been appointed by the trust to handle the sale of the decedent's property. This could be an executor or executrix of the estate, an appointee of the trust, or various other names but no matter the title the fiduciary duty remains the same to protect and finalize the trust and whatever is in the trust.
You should be able to have a complete digital or printout of the Trust documents as the title company, attorneys, and other legal factors can record the trust and assist in making sure it's executed properly. Just know that paying out any relative's portion comes after all debts including taxes have been settled in the estate.
Many Trusts have a non-contest clause built in that will eliminate or disqualify anyone from receiving their share or distributed monetary funds from the sale of the estate if they were to contest any part of the sale or document.
An executor is a person who will help execute the plan you laid out in your last will and testament. A trustee is responsible for managing a trust on behalf of its beneficiaries.
