Probate and estate planning administration for Guernsey domiciliaries

Through our executorship company, Carey Olsen Client Services (Guernsey) Limited, we provide a professional estate administration service for family members, individuals, lawyers or other professionals who are acting as executors or administrators who are heirs of a deceased person’s estate.

Why do I need a Guernsey grant of probate or administration?

Guernsey is an independent legal jurisdiction for estate administration purposes. When a person dies leaving assets in Guernsey it is likely their personal representative will be required to obtain a Guernsey Grant of Probate or Administration in order to receive the Guernsey assets. For smaller estates, the value of which varies from institution to institution, the local institution may be willing (but is not obliged) to release the funds to the personal representative in return for an indemnity.

The Bailiwick of Guernsey Probate Registry issues a Grant of Probate if the deceased left a Will or a Grant of Administration if they died intestate.


If assets are held in joint names, the assets will usually pass to the surviving account holder on production of the death certificate.

Will or intestacy

If the deceased died without making a Will he is said to have died “intestate”. Under these circumstances it is necessary to establish who is entitled to administer the deceased’s estate. This will need to be established by an affidavit of lawful heirs sworn by a Guernsey advocate.

What is an executor/administrator?

An executor is the personal representative of the deceased who is named in the Will. An administrator is the person appointed as the personal representative in an intestate estate or where the executor named in a Will is not applying for probate. An application for a Grant for the estate of a Guernsey domiciled individual requires a personal appearance at the Bailiwick of Guernsey Probate Registry by the executor or administrator or their duly appointed attorney. In the event the executor or administrator is not resident in Guernsey the Bailiwick of Guernsey Probate Registry can prepare a postal oath to be sworn outside of the Island before a notary public or someone authorised to administer oaths. Carey Olsen Client Services (Guernsey) Limited is our in-house executorship company which provides an independent estate administration service including acting as agent for a non-Guernsey executor or administrator.

What documents are required?

  • A death certificate. A certified copy of the death certificate with translation if appropriate.
  • Guernsey Will. The original Guernsey Will (if any).
  • Details of assets. Confirmation of the gross sterling value of the deceased’s worldwide estate unless either the Will is restricted to Guernsey assets or a grant of representation has already been obtained elsewhere when only confirmation of the gross sterling value of Guernsey assets will be required. This will not include any realty whether situate in the Bailiwick of Guernsey or elsewhere (unless it is owned by a company). Confirmation from a least one local institution which holds the deceased’s assets that a Guernsey grant is required.
  • Letter of engagement and terms of business. A letter of engagement which incorporates our terms of business signed by the personal representatives, beneficiaries or heirs.
  • Client Identification. A certified copy of passport(s) and utility bill(s) or bank statement(s) (of no more than 3 months old) confirming the residential address(es) of the proposed personal representative(s).

What documents may be required?

  • Affidavit of lawful heirs. An affidavit in the form required by the Bailiwick of Guernsey Probate Registry sworn by a Guernsey advocate confirming who is entitled to share in the succession under Guernsey law. This will also enable the Bailiwick of Guernsey Probate Registry to establish who is entitled to administer the deceased’s estate.
  • Affidavit as to due execution. This will be required on the first proving of the Will in Guernsey in the event the Will was not signed in Guernsey to prove that the Will was duly executed in accordance with the relevant law and is therefore capable of being admitted to proof in Guernsey.
  • Affidavit of handwriting. This will be required as evidence that a holographic Will presented for probate is in the handwriting of the deceased. If the affidavit is provided by the deceased’s professional adviser, only one affidavit is required, otherwise the Bailiwick of Guernsey Probate Registry will require two affidavits.
  • Translations. The professional translation of documents may be required.
  • Other documents and information. Depending on the circumstances other documents and information may be required.

All original documentation will be retained by the Bailiwick of Guernsey Probate Registry.


There are no death duties, estate duties or inheritance taxes, capital gains taxes or value added taxes on estates. The Bailiwick of Guernsey Probate Registry charges its fees based on the value of the estate. The value of the estate is always taken as the gross value (i.e. before deduction of debts and liabilities) of the assets that are required to be declared.

The value is always taken at the date of death. The deceased’s assets to be valued for these purposes are his movable assets. 

By way of guidance the Bailiwick of Guernsey Probate Registry charges its fees on a sliding scale. For an estate up to £50,000 a fee of £150 will be charged, for an estate up to £60,000 a fee of £175 will be charged, for an estate up to £70,000 a fee of £200 will be charged, and for an estate up to £80,000 a fee of £225 will be charged. In the case of amounts over £80,000 for each additional £10,000 or parts thereof the fee is increased by £50, up to a maximum of £250,000. There are small charges for certified copies, powers of attorney, oaths, deeds of renunciation, power reserved statements and other documents, the details of which can be provided on request.

Carey Olsen’s fees and those of Carey Olsen Client Services (Guernsey) Limited are based principally on time costing and complexity and we would be happy to provide estimates depending on the circumstances of each particular case.
