How will your estate handle conflict?

So many details to consider, and who has the final say;

When testators are considering the persons that they wish to act as their executors and trustees, consideration should also be given as to the manner in which the persons chosen will make decisions in the event that a disagreement or deadlock emerges among them.
Unless the testator indicates otherwise, executors and trustees must make decisions unanimously.  If a testator wishes to appoint multiple executors or trustees, then consideration should be had as to how those persons will make decisions.  Providing for majority decision-making is a common technique that is used in order to address any disagreements that may arise among multiple executors or trustees, but other situations may require other decision-making procedures.

You need to ask and appoint responsible people to deal with your issues and requests.

I recently learned that if appointed, my heirs, would be responsible to conclude your estate. An incredible and time consuming hardship for the unprepared.
