Compensation for the Trust Administrator
We recommend selecting something in line with the typical payments in your state. If you are significantly below, your administrator may choose not to administer your estate, and it could be difficult to find a professional administrator as a replacement. Most states allow any "reasonable" fee. Others have maximum fees they will allow an administrator to charge. Take a look at this article to get an idea of where your state stands. If they aren't on the list, then they will allow any "reasonable" fee.
The range of fees differs broadly depending on the complexity of the trust, value of the estate, and whether the trustee is a professional trustee company, a lawyer, or a trusted family member or friend.
For a professional trustee company, you're probably looking at .5% to 2% of the gross estate annually to administer the trust. If the estate isn't big enough, though, they're not going to do it at these price points.
For a lawyer, you're probably going to need to spend between $125 and $250 hourly for those service.
For a close friend or family member, $25–$50 hourly is probably reasonable. Often these kinds of administrators will have a right to compensation but choose not to bill the trust.
As a general rule, the larger and more complex the estate, the more you'll want to get a professional involved, and the more your estate will have to pay. And just like anything else in this trust, you can always change your mind and amend the trust later as circumstances change.
