DIY Will Kits Versus a Lawyer

7 Jun 2026
The cheapest will is not the one with the lowest fee. It is the one that works when it is needed. (Weighing the trade-off honestly.)

A do-it-yourself will kit or online template is inexpensive and fast. A lawyer costs more and takes longer. The right choice depends entirely on how complex your estate and family are.

The case for DIY. For a straightforward situation — modest assets, a clear set of beneficiaries, no business and no blended family — a good template, correctly signed and witnessed, can produce a valid will at low cost. The main risk is in execution: getting the witnessing wrong, leaving the residue undisposed, or using wording that does not say what you meant.

The case for a lawyer. Complexity is where professional drafting pays for itself. A blended family, a child with special needs, a business, property held with others, assets overseas, or any wish that needs careful structuring (a trust, staged gifts, conditions) all benefit from an expert eye. A lawyer also reduces the risk of a will being challenged for unclear wording or doubts about capacity.

The hidden asymmetry is the heart of the decision. A DIY will saves a few hundred dollars now; a defective DIY will can cost the estate far more later in legal fees, delay and family dispute — and you will not be there to fix it. Because the error surfaces only after death, it can never be corrected.

A reasonable rule: use a template only if your estate is genuinely simple, and engage a professional the moment any complication appears. When in doubt, a single paid review of a draft is a modest price for certainty.

Illustrative example: cost today versus risk later

The chart sets the two options against each other on what matters — upfront cost versus the risk and potential cost of an error that only surfaces after death. DIY wins on price; professional drafting wins on certainty. The complexity of your estate decides which should weigh more.
