Although the role of an executor and trustee is different, there is a lot of overlapping and they are generally the same people who would act on both roles.
With just a few clicks, you can choose whom you would like to be your executors/trustees.
Their role includes:
Collecting your Will and bringing it to the court for probate.
Liaising with the court or solicitor to collect your estate.
Valuing your assets and settling estate duty formalities (if applicable).
Clearing any of your debts and liabilities.
Distributing your estate in accordance with your Will.
If there are minor children, they would hold your assets on trust until the children reach adulthood.
