How much does it cost to go through probate? You’re going to need to hire an attorney, pay court costs, and administration fees. Roughly five percent of the value of the estate is what you’re looking at to pay all those fees. So think about it: if you only have a hundred thousand dollar estate, it’s five thousand dollars, but if you have a million dollar estate, You’re looking at close to fifty thousand dollars. So it’s really important to figure out what assets you can get out of the probate process To reduce those costs and fees and save your estate money in the long run.
