In order to cash the money orders you will need to open a probate estate if one has not been opened already in either of their names. After the probate estate is opened, and a personal reprsentative is appointed, the personal representative should be able to cash the money orders. The money orders would then have to be distributed according to the terms of the will, or intestate succession if there is no will. If there are no other assets to probate and the checks are less than $20,000.00, I would recommend opening a small estate which is a simplifed probate process to transfer smaller assets and the appointment of a personal representative is not necessary. You should be able to cash the money orders at a bank or check cashing service. If they will not cash the money orders, I would recommend contacting Moneygram directly. In regards to the fee, it is likely the service charge is enforceable.
