How much does a trust amendment cost on average?

Amending a trust usually costs about 300 to 1,000 dollars through an attorney, depending on how extensive the changes are. A small tweak like updating a trustee or beneficiary is on the lower end, while a major overhaul, sometimes done as a full restatement, costs more. It's far cheaper than creating a new trust from scratch. Keeping your trust current after big life changes is worth the modest expense.
