of their duties is to apply to the Probate Division of the High Court for a grant of probate. An executor can apply to a local probate registry for a grant themselves but most people use a probate practitioner such as a solicitor. If an estate is small, some banks and building societies allow the deceased's immediate family to close accounts without a grant, but there usually must be less than about £15,000 in the account for this to be permitted. Asset distribution The persons who are actually given the job of dealing with the deceased's assets are called "personal representatives" or "PRs". If the deceased left a valid will, the PRs are the "executors" appointed by the will—"I appoint X and Y to be my executors etc." If there is no will or if the will does not contain a valid appointment of executors (for example if they are all dead) then the PRs are called "administrators". So, executors obtain a grant of probate that permits them to deal with the estate and administrators obtain a grant of administration that lets them do the same. Apart from that distinction, the function of executors and administrators is exactly the same. Probate requirements A requirement of the probate process is the valuation of the estate.

Contesting the circumstances of a will's creation An applicant may challenge the validity of a person's will after they have died by lodging a caveat and requisite fee at the probate registry. This prevents anyone from obtaining a grant of probate for that person's estate for six months, which the applicant can shortly before that point apply to extend. A caveat is not to be used to extend the time for bringing a claim for financial provision from a person's estate, such as under the Inheritance (Provision for Family and Dependants) Act 1975. The court can order costs against an applicant using a caveat for that purpose. To challenge the caveat, the intended executor sends a completed "warning" form to the probate registry. This document will be sent to the person who entered the caveat, and for the caveat to remain, they will have to enter an appearance at the probate registry. This is not a physical appearance; it is a further document to
