A solo wills and trusts practice runs on a short list of repeated jobs. Draft a will or a revocable living trust. Get it signed. Collect the retainer into trust without touching it early. Bill the flat fee. Tell the client where their documents are. None of that is exotic, yet most attorneys end up paying for three or four separate tools to cover it, and at least one of those tools costs more than the rest combined.
This guide walks through what a solo estate planning attorney actually needs from software in 2026, what the WealthCounsel-style stack really costs once you add everything up, and how the main options compare on price and scope.
What estate planning solos actually need
Strip away the marketing and the job comes down to four moving parts. Skip one and you patch it with a spreadsheet, a separate login, or unbilled hours.
- Document drafting. Wills, revocable living trusts, durable powers of attorney, healthcare directives, and the engagement letter that starts the matter. This is the core. The faster you go from intake to a clean first draft, the more matters you can carry.
- IOLTA trust accounting. Estate planning runs on retainers, and a retainer is client money you cannot spend until it is earned. You need separate ledgers per client, a record that never lets a single client balance go negative, an audit trail, and an export your state bar will accept. Commingling or an overdraw here is how good attorneys end up in front of a disciplinary board.
- Billing. Most estate plans are sold flat-fee, but you still hit the occasional hourly matter. You want both, plus invoices that pull cleanly from the matter.
- Client portal and signing. Older clients do not want to dig through email threads. A portal where they review, e-sign the engagement letter, and find their finished documents removes a stack of phone calls.
Conflict checks belong on that list too. They are quick, but skipping them on a contested estate is the kind of mistake that follows you.
The real cost of the WealthCounsel stack
WealthCounsel's Wealth Docx is a strong drafting engine. Attorneys reach for it on complex trusts because the document assembly is deep. But it is drafting only. It does not handle your trust accounting, it does not invoice, and it does not give your client a portal.
It also costs roughly $500 a month on an annual commitment, with no free trial. That number is just the drafting line. To run an actual practice on top of it, a solo typically bolts on:
- A separate IOLTA-capable accounting tool.
- A billing or invoicing tool.
- An e-signature service such as DocuSign, which runs $75 to $450 a month.
- Sometimes a separate client portal on top of all of it.
Add it up and a solo can clear $600 to $900 a month before a single will is signed, spread across four logins that do not talk to each other. Matter data lives in one place, the trust balance in another, the invoice in a third. Reconciliation becomes a manual, error-prone chore, and trust accounting errors are exactly the kind you cannot afford.
The hidden tax is reconciliation. When drafting, accounting, and billing live in separate tools, you are the integration. Every matter means re-keying the same client and the same dollar figures three times. That is unbilled time, and it is where mistakes hide.
The four main options compared
Here is how the realistic choices line up for a solo estate planning attorney. Prices are starting points as of mid-2026.
| Software | Starting price | AI drafting | IOLTA built-in | All-in-one | Best for |
|---|---|---|---|---|---|
| ContractKit | $49/mo | ✓ | ✓ | ✓ | Solo EP |
| WealthCounsel | ~$500/mo | Assembly | ✗ | ✗ | Complex drafting |
| Gavel | $83/mo | Workflows | ✗ | Partial | Automation |
| Clio + Draft | $49/user + add-ons | Add-on | Higher tier | ✓ | Growing firms |
WealthCounsel (Wealth Docx)
The drafting depth is real, and for a firm that lives in complex, high-net-worth trust work it can earn its keep. For a solo doing standard wills, trusts, and POAs, you are paying around $500 a month for one of four functions and stitching the rest together yourself. No free trial means you commit before you see how it fits your day.
Gavel
Gavel is a no-code document automation and workflow builder, starting around $83 a month with a 7-day trial. If you love designing your own intake-to-document pipelines, it rewards that. It is not a full practice platform, though. Trust accounting and billing are not its job, so a solo still ends up with extra tools and the same reconciliation gap.
Clio + Clio Draft
Clio is the broad practice-management platform. Drafting comes through Clio Draft, which is an add-on layered on top of per-user Clio plans that start around $49 per user. Its AI sits in a separate product, Clio Duo, and IOLTA-grade trust features tend to live on the higher tiers. It is a solid path for a firm that is growing and adding staff, but for a single attorney the per-user-plus-add-on math climbs fast.
ContractKit
ContractKit is built to be the whole stack for a solo. One flat price, every function included, no add-on menu to decode. More on where it fits below.
Where ContractKit fits
ContractKit is the all-in-one option aimed squarely at solo estate planning attorneys. The Solo plan is $49 a month, flat, for one attorney. There is also a Firm plan at $99 a month for up to five users, and Enterprise at $249. Every plan, including the $49 one, includes the full set:
- AI drafting for wills, revocable living trusts, powers of attorney, healthcare directives, and engagement letters.
- IOLTA trust accounting with separate client ledgers, no-overdraw protection, a full audit trail, and export.
- Matters and time tracking.
- Flat-fee and hourly invoicing in the same place as the matter.
- A client portal with e-sign, plus conflict checks.
Because drafting, trust accounting, and billing share the same matter, there is nothing to re-key and nothing to reconcile across tools. You draft the trust, the retainer lands in that client's ledger, the flat fee invoices from the same record, and the client signs in the portal. There is a 14-day free trial with no card required, and billing is month-to-month with no annual contract, so you are not locked in before you have run real matters through it. ContractKit is US-focused, which keeps the trust accounting and document templates aligned with how American estate planning actually works.

What to check before you switch
Before you move a practice onto any tool, run it through these questions. They separate software that demos well from software that survives a busy month.
- Does the trust accounting actually prevent an overdraw? A ledger that lets a single client balance go negative is a liability, not a feature. Confirm the no-overdraw protection and the audit trail, and check that the export matches what your state bar expects. If you want depth here, read our guide to IOLTA trust accounting software for law firms.
- Are the document templates current for your state? Estate planning is state-specific. Generate a sample will and a revocable living trust during the trial and read them as if a probate judge will.
- Is the price flat, or does it climb? Per-user pricing and add-on menus look cheap on the headline and add up fast. Confirm what the all-in number is for the way you actually work.
- Can you leave? Month-to-month beats an annual lock-in when you are still learning whether the tool fits. And check that you can export your matters, documents, and trust ledgers if you ever move.
- Is there a real trial? You cannot judge a drafting engine from a sales call. A free trial without a card, like ContractKit's 14 days, lets you push real work through before you commit a dollar.
Frequently asked questions
What is the best estate planning software for a solo attorney?
For a solo doing standard wills and trusts, the best fit is an all-in-one that covers drafting, IOLTA trust accounting, billing, and a client portal in one price. ContractKit does that at $49 a month flat. WealthCounsel is stronger for complex, high-net-worth trust drafting but costs around $500 a month and covers drafting only, so you add separate tools for everything else.
Do I really need IOLTA trust accounting built into my software?
If you take retainers, yes. Retainers are client funds you cannot spend until earned, and your state bar requires separate ledgers, no commingling, and a clean audit trail. Built-in trust accounting that shares your matter data removes the manual reconciliation between a drafting tool and a separate accounting tool, which is where most trust errors start.
How much should estate planning software cost a solo?
A solo can run a full practice for around $49 a month with an all-in-one like ContractKit. The WealthCounsel-style stack, once you add IOLTA accounting, billing, and e-signature such as DocuSign at $75 to $450 a month, commonly lands between $600 and $900 a month across multiple tools.
Can I try estate planning software before committing?
It depends on the vendor. ContractKit offers a 14-day free trial with no credit card and month-to-month billing. WealthCounsel has no free trial and an annual commitment, while Gavel offers a 7-day trial. Always generate a real document and test the trust ledger during any trial before you sign anything.
Run your next matter on one tool, not four. ContractKit puts AI drafting, IOLTA trust accounting, flat-fee and hourly billing, and a client portal with e-sign in a single $49/mo plan built for solo estate planning attorneys. Start a 14-day free trial, no credit card required, and put a real will or trust through it before you decide.
