What are the hidden costs of a solicitor will?

Most people look at the upfront price tag of a Will (£150 to £400 with a solicitor), but fail to calculate the ongoing costs across a lifetime:

  • Update Fees: Life changes (marriage, birth of children, buying a house, moving) require Will updates. Solicitors charge £100–£200 for every codicil or re-draft. Farewill charges a £10/year ongoing subscription. SwiftWill updates are 100% free forever.
  • Document Storage Fees: Many companies charge £20–£40 per year to store a piece of paper in a safe. You can store your Will at home or deposit it with HMCTS Probate Service for a one-off £33 fee.
  • Corporate Executor Trap: The biggest hidden cost. Banks and solicitors often insert themselves as executors, taking 2.5%–5% of your total estate upon your death. On a £400,000 estate, that is £10,000–£20,000 lost from your family's inheritance.

Frequently asked questions

Why do solicitors charge so much for simple wills?

High-street solicitors carry heavy office overheads and bill by the hour (£200-£400/hr). For a standard estate in England and Wales, document-preparation software produces identical legally binding results under Section 9 of the Wills Act 1837 for £35.

What is a professional executor fee and why is it dangerous?

If a solicitor or bank names themselves as a professional executor in your will, they charge 2.5% to 5% of your total estate value upon your death. On a £350,000 house, that takes £8,750+ directly from your children's inheritance. SwiftWill never inserts corporate executors.
