A caveat costs £3 and lasts 6 months. It stops the Probate Registry from issuing a grant. Enter it online or by post (form PA8A). It can be renewed. The executor can issue a Warning Notice, which forces the caveator to respond within 8 days or lose the caveat.
A caveat is the essential first step in any contentious probate dispute. By entering a caveat, you instruct the Probate Registry not to issue a Grant of Probate to the executor without first notifying you, giving you time to investigate and take legal advice without the estate being distributed.
This guide explains exactly how to enter a caveat, the process after it is entered, the Warning Notice procedure, renewal, and when a caveat should and should not be used.
Once a caveat is entered:
A caveat does not prevent the executor from continuing to manage urgent matters relating to the estate (such as paying care bills or maintaining a property) — it only prevents the formal legal authority of the grant from being obtained.
There are two methods:
Apply online via the HMCTS probate service at apply-for-probate.service.gov.uk. You will need to create an account or log in, then select “Enter a caveat” and complete the form with the deceased's details. Pay the £3 fee by card. The caveat is entered immediately.
Complete form PA8A (available from the HMCTS website or any Probate Registry) and post it with the £3 fee (cheque or postal order) to the Principal Registry of the Family Division, First Avenue House, 42–49 High Holborn, London WC1V 6NP.

A caveat lasts 6 months from the date of entry. Before it expires, you can renew it for a further 6 months by applying to the Probate Registry and paying a further £3 fee. There is no limit on the number of times a caveat can be renewed — a caveat can remain in place indefinitely if renewed before each expiry.
You should also consider entering a standing search (see our guide on standing searches in probate) alongside the caveat — a standing search notifies you if a grant is issued, which is useful if you are not certain whether a grant has been applied for.
Once a caveat is entered, the executor (if they wish to proceed with the grant) can issue a Warning Notice. The process is:
Filing an Appearance commits you to contentious court proceedings. You should only file an Appearance if you have legal grounds for challenging the will and are prepared to litigate. Legal advice before filing is strongly recommended.
You should consider entering a caveat if:
You should NOT enter a caveat without legal justification — doing so to harass or delay an executor without a genuine claim can lead to a costs order against you.
