Will writing software that keeps up with the appointment.
Wills, LPAs, trusts, severances and letters of wishes, drafted through questions instead of templates — with the client record, the follow-ups and the invoicing in the same place.
Wills, LPAs, severance and other documents, drafted against the client record.
Will writing software drafts wills and related documents from structured answers instead of from a template you edit by hand. Willo is a UK system built for professional estate planners: it drafts wills, Lasting Powers of Attorney, trusts, severances of joint tenancy and letters of wishes, validates each document before it leaves you, and keeps the client record, email and invoicing in the same place. It costs £150 a month per drafter, with unlimited documents and no contract.
What Willo drafts#
| Document | What it covers |
|---|---|
| Wills | Single wills, mirror wills, and wills containing testamentary trusts |
| Lasting Powers of Attorney | Health and Welfare, and Property and Financial Affairs, populated ready for the Office of the Public Guardian |
| Trusts | Property protection, life interest and discretionary trusts |
| Severance of joint tenancy | The notice and the supporting Land Registry paperwork |
| Letters of wishes | Guidance to trustees, funeral directions and digital asset instructions |
| Supporting paperwork | Fact finds, client care letters, quotes and invoices |
Every document type is included in the one price. There is no separate trust module and no per-document charge — a point worth checking against whoever you are comparing us with, because packaging documents separately is the norm in this market rather than the exception.
How the drafting actually works#
Questions in the order you ask them#
The flow follows the shape of a real appointment. You are asking about the family before you ask about the residue, and about the house before you ask about trusts, because that is how the conversation goes. The client sitting opposite can follow along, which matters more than it sounds — people sign documents they understood.
It stops you making the classic mistakes#
Validation runs as you go. It catches the executor you appointed but never named, the specific gift that disposes of an asset you already gave away, the attestation that has not been completed, the guardian appointment with no substitute. These are the errors that come back as complaints two years later, and catching them at the desk costs nothing.
Save it half-finished#
Take instructions at a kitchen table on a Tuesday, finish it at your desk on a Wednesday. Progress saves against the client record, so nothing lives in a notebook between the two.
The templates are our problem, not yours#
When legislation changes, or the Office of the Public Guardian reissues a form, we update Willo. You do not maintain a clause library, you do not diff a Word document against last year's version, and you do not find out at the wrong moment that your precedent is out of date. This is the single largest hidden cost of drafting in Word, and it is invisible until it bites.
What happens after the document#
This is where most will writing software stops and hands you back to your inbox. Willo does not, because drafting is the fast part of the job and everything after it is where the money leaks.
- The client record — family tree, assets, notes, every document and every email against the person, with a pipeline from first enquiry to signed and stored.
- Email, SMS and video — send from your own domain over IMAP and SMTP, run SMS campaigns, hold video meetings, without three more subscriptions.
- Invoicing and payments — branded quotes and invoices, expenses, GoCardless Direct Debit, and an accounts view that tells you what the month actually did.
- Print and post — finished packs printed, bound and posted under your branding.
- Ask Willo — an assistant inside the software for the "how do I" questions.
Who uses it#
Solo practitioners and small firms who want to handle more clients without hiring. Will writers expanding into LPAs and trusts, which is where most people stall. Private client solicitors running it inside a department for faster turnaround. People who have just finished training and have no client base yet.
We have written separately for will writers, estate planners, private client solicitors, financial advisers, accountants and people starting out.
What it costs, plainly#
£150 a month. Per drafter. Unlimited documents. Every feature included. No setup fee, no minimum term, no notice period, no exit fee.
There is no free trial, and that is deliberate — we explain why on the pricing page. The short version is that a fortnight alone with unfamiliar software and no real client in front of you tells you nothing useful. A walkthrough and then a month with everything switched on tells you everything.
How it compares to the alternatives#
| Willo | Arken | WillSuite | Sure Will Writer | |
|---|---|---|---|---|
| Published price | £150, no VAT | From £107 + VAT | £150 + VAT per user | £150–£180 + VAT |
| Actually leaves your account | £150 | £128.40 | £180 | £180–£216 |
| Charged per | Drafter | Document pack | User | User |
| Documents | Unlimited | Capped by pack | Unlimited, fair usage | Unlimited |
| Trust drafting | Included | +£40 + VAT | Included | Included |
| Commitment | None | Annual | Rolling monthly | Monthly |
Prices taken from each provider's own public pricing page on 14 September 2026. Willo is not VAT registered, so the £150 is the whole amount — which is worth £30 a month to any practice that is under the VAT threshold and cannot reclaim it. The full picture is on the comparison pages.
Why this is not just software#
Willo is built by Project Will, the UK's support body for estate planners, who have been doing this since 2009 and support more than 500 practitioners. That matters in practice rather than in principle: the people writing the clauses draft for a living, the walkthrough is done by someone who uses the software daily rather than a salesperson reading a script, and if you want training, it is free and properly registered — Project Will is a UKRLP-registered training provider, UKPRN 10101187.

Questions people actually ask.
What is will writing software?
Will writing software is a drafting system that produces wills and related estate planning documents from structured answers rather than from a word processor template. You answer questions about the client's family, assets and wishes; the software assembles the correct clauses, checks them against each other, and outputs a finished document. Professional systems in the UK also handle Lasting Powers of Attorney, trusts and letters of wishes, and most now include some form of client record.
How much does will writing software cost in the UK?
Between roughly £55 and £180 per user per month in September 2026. Willo is £150 a month per drafter with unlimited documents and no VAT added. WillSuite is £150 + VAT per user. Arken starts at £107 + VAT for a ten-document pack. Sure Will Writer is £150 + VAT for Society of Will Writers members and £180 + VAT otherwise. Full breakdown on the cost of will writing software page.
Do I need a qualification to use will writing software?
Not to use the software, and not to write wills. Will writing is not a reserved legal activity in England and Wales, so there is no statutory qualification requirement. Some providers still gate their software behind trade body membership. We do not. Project Will run free UKRLP-registered training if you want it, and most people take it — see training.
Does Willo work for Scotland?
Willo drafts for England and Wales. Scots succession law differs enough — legal rights, different execution requirements — that a bolted-on module does a disservice to clients. We would rather say so than sell you something that half fits.
Can I use my own wording and branding?
Yes. The will design, invoice design, quote design and email templates are all yours to brand, and documents go out under your name, not ours. Print and post fulfilment is unbranded to the client too.
