Will Writing & Probate Legal Fee Cost Calculator UK 2026/27

Estate planning in the UK involves two main legal stages: drafting a legally valid Will during your lifetime, and applying for a Grant of Probate to administer the estate after death.

While writing a straightforward solicitor-drafted Will costs £220 to £350, applying for probate and administering a deceased person’s estate incurring HMCTS court fees (£300) and potential solicitor estate administration fees (1% to 2.5% of estate value).

📑 Common Pitfalls & Estate Planning Warnings

1. Dying Intestate (Without a Valid Will): If you die without a Will, your estate is distributed according to statutory Rules of Intestacy. Unmarried cohabiting partners receive £0.00 under intestacy rules, regardless of how many decades they lived together.
2. Appointing a Bank or Solicitor as Sole Executor: Banks and solicitors appointed as sole executors in a Will charge maximum top-tier fees (up to 4% of estate value) to administer the estate. Always appoint family members or trusted friends as primary executors, giving them the freedom to hire solicitors on fixed-fee terms if needed.
3. Invalidating a Will via Improper Witnessing: Under Section 9 of the Wills Act 1837, a Will MUST be signed by the testator in the presence of two independent adult witnesses present at the same time. Beneficiaries (or their spouses) must NEVER act as witnesses, or their inheritance will be void.
