What is a reasonable fee to just update a will, power of attorney, and living will?

I like to think our legal fees are reasonable, so I will answer your question based on what my firm typically charges for such documents. An update to a will is typically done through a codicil. We typically charge approximately $125 for a codicil. However, for just changing the name of the executor, we would probably charge approximately $75 to $100 for such a codicil. Unfortunately, to update a (durable) power of attorney and health care proxy (I assume you mean health care proxy and not living will since a living will is a directive to a doctor so there is no named agent), you will need new documents (even to just change the names of the respective agents). We typically charge approximately $75 for each such document.

Each attorney sets his own fee schedule and some attorneys do not charge for an initial meeting. Also, attorney fees vary according to the attorney's experience as well as the location of the attorney within the state. Usually the attorney who originally drafted the documents charges a minimal fee to update this documents. However, if you have moved from another state, you would need to meet with a Massachusetts attorney.

It will vary by attorney of course, but it would probably be a couple hundred dollars. If you are going back to the attorney who drafted the documents, it may be less since they are familiar with your situation. If it is a new attorney, they may want to have a "get to know you" meeting. Usually the change to the Will can be done with a codicil (like an amendment) and then the power of attorney and living will would just be done again from scratch, since those aren't usually amended.
