There is no requirement that an executor must accept the executorship role, even if it was agreed to do so. But relinquishing executorship should be done as soon as practical if you don’t wish to act and have not dealt with the estate, (intermeddle). You can resign your appointment as executor by renouncing your right to probate of the deceased’s will, that is you renounce probate.
Probate is the official process to establish or prove, whether a deceased person’s will or testamentary document is valid and intended to be their last will.
A grant of probate is the document issued by the Court of Probate after completion of an examination process. A type of grant of representation, it is an order of the Court certifying that the executor (or personal representative) named in the document is lawfully authorised to administer the estate of the deceased person. It is also official recognition that the will (which may include codicils) was proved to be valid by the Court and intended to be their last will. This article is about probate, which only applies when a will was left.
The residue of a deceased person’s estate is basically what is left over after the payment all costs in connection with the estate. That is, payment of funeral expenses, costs incurred in the administration of the estate, payment of the deceased’s debts, discharge of any liabilities and the distribution of any specific gifts made under the will.
