In your Estate Planning the Executor can be anyone over 18 that you choose. The person should be someone you trust to carry out your estate administration intentions. In most cases they are family members. In our experience people younger than 25 are not as equipt to handle the responsiblity of being an Executor. In Pennsylvannia you may also choose a friend over 18. Again make sure they are someone you trust and are capable of following your instructions. You may also choose various professional advisors from accountants to lawyers and financial advisors. Be aware if there are any ethical restrictions in that particular profession. Make sure you know what they will charge and their experience level. You may also consider a bank or institutional fiduciairies if you do not have a close family member or friend or need a neutral third party.
