If you are putting together your will, particularly if it's the first time, understanding everything you need to cover can be a challenge. One of the first steps, though, is to pick your executor. This decision is important because the executor of your estate is the person you are trusting to take care of all of your final debts and the disposition of your assets. That makes the position one of trust, and it also complicates the choice, because the people you are most likely to trust the most are also likely to be beneficiaries, which could potentially put them in the position of having a conflict of interest.
The probate process is complex under normal circumstances, but certain factors can add significant complexity - and contentious disputes - to the equation.
