Why DIY Estate Plans Fail
in California Courts
LegalZoom, Trust & Will, and similar services sell you a document. They cannot give you a plan. Dustin MacFarlane — one of fewer than 1% of California attorneys certified as an Estate Planning, Trust & Probate Law Specialist — has spent 17 years fixing the mistakes these services create. Here are the five most common — and most costly — failures.
DIY vs. Certified Specialist — At a Glance
| Feature | LegalZoom / DIY | CPT Law — Certified Specialist |
|---|---|---|
| Trust Funding Assistance | ❌ None | ✅ Deed preparation + account retitling guidance |
| Execution Supervision | ❌ You're on your own | ✅ Attorney-supervised signing |
| Proposition 19 Compliance | ❌ Generic template | ✅ California Rev. & Tax. Code § 63.2 compliant |
| Incapacity / POA | ⚠️ Generic form — often rejected by banks | ✅ Institution-ready California-specific language |
| Spendthrift / Inheritance Protection | ❌ Outright distribution only | ✅ Probate Code § 15300 spendthrift provisions |
| Medi-Cal Planning | ❌ Not addressed | ✅ MAPT and asset protection strategies available |
| Ongoing Review | ❌ One-time document | ✅ Plan updates as laws change |
| Cost if It Goes Wrong | 🔴 $20,000–$60,000+ in probate + lost tax benefits | ✅ Prevented entirely |
The Top 5 Fatal Flaws of DIY Wills and Online Trusts in California
Based on 17 years of reviewing, repairing, and administering California estates — these are the mistakes Dustin sees most often, and the ones that cost families the most.
Fatal Flaw #1
The Trust Is Never Funded
This is the #1 reason DIY trusts fail — and it happens to nearly every one of them.
Fatal Flaw #2
Execution Defects — Signed Wrong, Witnessed Wrong, or Notarized Wrong
A will or trust that fails California's execution requirements is legally worthless.
Fatal Flaw #3
No Proposition 19 Planning — Triggering a Massive Property Tax Reassessment
California's Proposition 19 changed the rules in 2021. Most DIY templates have not caught up.
Fatal Flaw #4
No Incapacity Planning — Court-Ordered Conservatorship Instead
A will only activates when you die. It does nothing if you become incapacitated.
Fatal Flaw #5
No Inheritance Protection — Children's Inheritance Exposed to Divorce and Creditors
A basic trust distributes assets outright. That means your child's inheritance is immediately available to their spouse, their creditors, and their bad decisions.

Frequently Asked Questions
Questions Dustin is asked most often about DIY estate plans in California.
Is a LegalZoom trust valid in California?
A LegalZoom trust document can be technically valid in California if executed correctly. The problem is not usually the document itself — it's what comes after. The trust must be funded (assets retitled into it), executed properly with correct witnesses and notarization, and drafted with California-specific provisions for Proposition 19, incapacity, and inheritance protection. Most LegalZoom trusts fail at one or more of these steps.
What is the most common DIY estate planning mistake in California?
Trust funding failure is the single most common mistake. Families create a trust but never transfer their home, bank accounts, or investments into the trust's name. When the person dies, the estate goes through probate — exactly what the trust was supposed to prevent.
How much does it cost to fix a DIY estate plan that went wrong?
If caught before death: a few thousand dollars to have a Certified Specialist review and correct the documents. If discovered after death: potentially $20,000–$60,000+ in probate court costs, attorney fees, and delays — plus the irreversible loss of Proposition 19 property tax benefits that can cost heirs tens of thousands of dollars per year permanently.
Can I use an online will if my estate is small?
California's simplified succession procedures (Probate Code § 13100) allow estates under $184,500 to transfer without full probate. If your estate is genuinely below that threshold and you have no real estate, an online document may be adequate. But if you own a home in the Sacramento area — where median home values far exceed $184,500 — a DIY will almost certainly leaves your family exposed to full probate.
What does a Certified Specialist do differently than a general attorney?
California State Bar Certified Specialists in Estate Planning, Trust & Probate Law — a designation held by fewer than 1% of California attorneys — have passed a rigorous specialty exam, completed advanced continuing education, and received peer references in the specialty. Dustin MacFarlane is one of these specialists. A Certified Specialist drafts documents knowing the specific California statutes, case law, and institutional requirements that generic templates and general-practice attorneys routinely miss.
