Avoid These Estate Planning Blunders: A Guide to Securing Your Legacy

Short answer: The estate planning mistakes that do the most damage in California are dying without a will, setting up a trust but never retitling assets into it, letting old beneficiary designations override the will or trust, naming the wrong executor or trustee, and skipping incapacity planning. Fix those five and you have addressed the mistakes that generate most of the probate litigation and family conflict Ridley Law sees. None of them require a large estate to matter.

What happens if I die without a will in California?

Probate Code § 6400 hands the decision to the state’s intestate succession statutes, not to you. For community and quasi community property, a surviving spouse takes all of it, their own half plus the half that belonged to the person who died, under Probate Code § 6401(a) and (b). Separate property is split differently: the surviving spouse gets everything if there are no surviving children, parents, or siblings; half if there is one child or no children but a surviving parent or sibling; and a third if there are two or more children, under Probate Code § 6401(c). If nothing passes to a spouse, the estate moves down a fixed line under Probate Code § 6402: children first, then parents, then siblings, then outward from there. Stepchildren who were never legally adopted and unmarried partners typically inherit nothing under this scheme, under Probate Code §§ 6401 and 6402, no matter how close the relationship was in life.

Dying without a will does not avoid probate. An intestate estate above the small estate threshold still goes through full, court supervised probate under the same statutory fee schedule that applies to any other estate, Probate Code §§ 10800 and 10810. Skipping the will does not skip the court process. It just means the court distributes your money using the state’s default rules instead of your instructions.

Does a trust actually avoid probate, or just make me feel better?

A will, by itself, never avoids probate. It only takes effect once a court validates it through the probate process. Only a funded revocable living trust moves assets to beneficiaries outside of probate. The word “funded” is where most do it yourself estate plans fail: the trust document exists, but the house, the brokerage account, and the bank account were never retitled into the trust’s name. On the day something happens to you, those un-retitled assets sit outside the trust and go through probate anyway, the same result you paid to avoid.

A living trust also does not, by itself, reduce income tax, property tax, or estate tax. California has no state estate tax and no state inheritance tax, Revenue and Taxation Code § 13301. A trust’s real value is privacy and probate avoidance, not tax savings, and it only delivers either benefit if the assets are actually inside it.

Why does the choice of executor or trustee matter so much?

An executor and a trustee are both fiduciaries who owe legal duties to the estate or the trust’s beneficiaries. A trustee specifically may not use trust property for personal benefit, Probate Code § 16004. If you die without naming anyone, the probate court appoints an administrator under a statutory priority order, Probate Code §§ 8460 through 8469, meaning a judge, not you, decides who runs your affairs. Naming someone disorganized, geographically distant, or already in conflict with your beneficiaries invites delay and, sometimes, a petition asking the court to compel an accounting or remove them, Probate Code § 17200. Choose based on capability and willingness, not just affection or birth order.

What happens when beneficiary designations don’t match the will or trust?

Assets held in joint tenancy, payable on death or transfer on death accounts, and retirement accounts or life insurance policies with a named beneficiary generally pass directly to whoever is named on the account, regardless of what the will or trust says. A beneficiary designation filled out at a job twenty years ago, naming an ex spouse or a sibling you have since fallen out with, controls over a will signed last year. This mismatch is one of the most common ways a person’s actual wishes get overridden after death, and it costs nothing to fix. Review every retirement account, life insurance policy, and payable on death designation every time you update your will or trust.

Do I need a power of attorney and health care directive too?

Yes. A power of attorney lets someone you trust manage your financial affairs if you become unable to, and a health care directive lets someone make medical decisions and states your wishes if you cannot speak for yourself. Without these documents in place, your family may need to ask a court to appoint a conservator, a process that is public and slower than naming your own agent in advance. These documents are ordinarily prepared alongside a will or trust as part of one complete plan, not tacked on afterward.

What to do next

Most of these mistakes are fixed with an afternoon of paperwork, not a lawsuit. Pull your current will or trust, your beneficiary designations, and your executor and trustee choices, and check whether they still match your life and your wishes. If you don’t have a will or trust at all, or you’re not sure whether your trust was ever funded, talk to an estate planning attorney before a life event forces the issue.
