Before you start — what PA13 is, and who it's for
PA13 applies in one situation only: you're representing yourself, and you hold a copy of the will rather than the signed original. It doesn't replace your probate application; it supports it, giving the Probate Registry the evidence it needs to accept the copy in place of the original.
Who can use this form
PA13 is for a litigant in person — someone applying for probate themselves, without a solicitor.
If you're a probate practitioner acting for the estate, don't use this form. HMCTS instead expects an affidavit or statement of truth, supported by exhibits, aimed at the same rule 54 order proving the copy will.
What it's asking you to prove
The legal test is whether the will was revoked — not just whether it's missing.
Under rule 54 of the Non-Contentious Probate Rules 1987, a copy can only be admitted to proof if the district judge or registrar is satisfied it reflects a will that genuinely existed and wasn't destroyed by the testator with the intention of revoking it. PA13 is the questionnaire that gathers the evidence for that decision.
When to submit it
Send PA13 together with your probate application (PA1P if there's a will, or PA1A if none survives to prove) — not separately and not in advance.
Expect the Registry to come back for further detail in complex cases, or where question 14 identifies someone who would be prejudiced by the copy being proved.
