Plain English
If you have been named as an executor in a will, you will need to sign this oath before the court will let you deal with the deceased’s assets. It is a simple declaration that you accept the role and will act honestly.
Submission Date
- The oath should be filed together with the probate application, typically within four weeks of the death, unless the court sets a different deadline.
- Preparation window: collect IDs, supporting records, and signatures in advance.
- Final review: verify names, dates, and required fields before submission.
What this form is for
- • When you are the sole executor named in the will.
- • When you are applying for a Grant of Probate for a deceased estate.
- • When the court specifically requests an Oath of Executor with the probate papers.
- • If you are a co‑executor, each executor must complete their own oath.
