to obtain letters of administration you need to file for a probate of the estate.  Texas has several options for probate.  The type of probate and the cost of the probate will depend on the size of the estate, the number of heirs, whether there was will (or not), and whether anyone desires to contest the estate.  Costs will also depend on the going rate in your area.Simple estates with little property can be handled for a lower price.  If the probate becomes more complex, then it will naturally cost more.I would suggest making a list of potential heirs and itemize the big ticket item of the estate.  Big ticket items are the cars, house, accounts, and things of significant value.  This does not include the everyday dishes, the sheets, or the lawnmower.  Once you have these two lists, set up consultations with at least three attorneys.  If you were to by a new car, you would look at more than one vehicle.  Attorney shopping is very similar.  Go with the one that understands your issues, that explains the process to you, and (most importantly) listens to you.  After visiting with three attorneys, you should be able to see a consistent trend of issues for your case, and the costs---such that you can identify who is trying to overcharge you.
