It is the executor who will have to make the biggest decisions and, unless someone complains, there will be little oversight from busy probate courts.
You need an executor who is trustworthy, understands financial matters, has the time to do the job properly, is willing to do the job, is patient and will seek the advice of experts, when necessary.
Finding someone who meets all of those qualifications can be a challenging task for many people. However, it is necessary, if you want your estate to go smoothly.
Fortunately, if you do not have a friend or family member who fits the bill, there is someone you probably know who can help steer you in the right direction.
While an executor will be administering your probate estate in probate court, it is possible to avoid probate entirely by using a revocable living trust. However, the same criteria apply to selecting your trustee; someone who is trustworthy, understands financial matters, has the time to do the job properly, is willing to do the job, etc.
An estate planning attorney can guide you in creating an estate plan that fits your unique circumstances. They can also advise you on a good choice for an executor or trustee.
