Divorce in California rewrites part of an estate plan automatically, but not all of it. Once the judgment is entered, most gifts and fiduciary roles given to a former spouse in a will or trust fall away by law. Employer retirement plans, joint title, and several other documents stay exactly as they were until someone changes them.
Most people facing this question have just finished, or are about to finish, a divorce that took months of disclosures, valuations, and negotiation. The judgment is signed or close to it. Then comes a quieter realization: the will, the trust, the 401(k) form, and the power of attorney were all drafted for a marriage that no longer exists. The worry is simple. If something happened tomorrow, who would actually receive the assets, and who would be making the decisions?
For owners of closely held businesses, executives holding RSUs and deferred compensation, and families with real estate portfolios or concentrated stock, the stakes of that question scale with the balance sheet. The property division in the judgment decides who owns what. The estate plan decides where it goes next. Those are two different legal systems, and they do not talk to each other on their own. This article walks through what California changes automatically, what it leaves alone, and how the pieces usually get lined up after a San Diego County divorce.
What California Law Automatically Changes After Divorce
California has a set of revocation-by-operation-of-law rules. "Operation of law" means the change happens because a statute says so, not because anyone signed a new document. When a marriage is dissolved or annulled, California law generally treats most gifts to the former spouse in a will or trust as failed, and removes the former spouse from fiduciary roles such as executor or trustee.
The mechanism matters. The document is not torn up. Instead, Cal. Prob. Code § 21386 supplies the rule for what happens next:
"If a donative transfer fails under this part, the instrument making the donative transfer shall operate as if the beneficiary had predeceased the transferor without spouse, domestic partner, or issue."
In plain terms, the will or trust is read as though the former spouse died first and left no children of their own through whom a gift could pass. Whoever the document names next in line takes over. That may be an alternate beneficiary, the residuary clause (the catch-all that sweeps up everything not specifically given away), or, failing both, the estate.
A similar framework reaches some nonprobate transfers, meaning assets that pass outside a will, such as pay-on-death bank accounts and transfer-on-death registrations. California's revocable transfer on death deed law, governed in part by Cal. Prob. Code § 5600, covers deeds made by transferors who die on or after January 1, 2016. That part of the code is currently scheduled to sunset on January 1, 2032, unless extended, though deeds signed before then keep their effect.
Timing is the part most often misunderstood. These revocations take effect when the judgment of dissolution is entered, not when the petition is filed and not while the case is pending. In San Diego County, that judgment is entered through the San Diego Superior Court Family Law Division. Until then, the former spouse is still a spouse for estate planning purposes.
One large category sits outside all of this. Employer-sponsored retirement plans governed by the federal Employee Retirement Income Security Act (ERISA), such as most 401(k) and pension plans, follow federal rules. California's automatic revocation statutes do not reach them.
What the Statutes Do Not Change: The Gaps That Remain Open Until Addressed
The automatic rules are a safety net with holes in it. Several of the most valuable assets in a high-net-worth estate fall through.
ERISA-governed accounts. A 401(k), 403(b), or company pension pays whoever is named on the plan's beneficiary form. In Egelhoff v. Egelhoff Ex Rel. Breiner, 532 U.S. 141 (2001), the U.S. Supreme Court held that ERISA preempts, or overrides, a state statute that tried to revoke a former spouse's designation automatically. The plan administrator pays the name on file.
IRAs. Individual retirement accounts are generally not ERISA plans, so state revocation rules may apply to them. How an IRA custodian responds in practice depends on its own account agreement, and custodians do not always know a divorce has occurred.
Life insurance. Group life coverage through an employer is often ERISA-governed and follows the form on file. An individually owned policy may be treated differently under California law, but the insurer's contract and whether it has notice of the divorce affect how smoothly a claim is paid.
Revocable living trusts. Gifts to a former spouse inside the trust fail by law, but the trust still exists with its old structure, old successor trustee provisions, and old distribution plan. It usually needs to be amended or restated.
Durable powers of attorney for finances. Cal. Prob. Code § 4154 revokes a former spouse's designation as attorney-in-fact (the agent who manages finances) when the marriage is dissolved. Nothing fills the vacancy, however, unless the document names a backup.
Advance health care directives. California law generally revokes a former spouse's designation as health care agent on dissolution, and the directive otherwise stays in place. A new directive fills the gap.
Joint tenancy real property. Title on record does not change because of a judgment. A deed has to be prepared and recorded with the County Recorder to reflect how the judgment divided the property. The mechanics of that division are covered in more detail in our guide to real estate in divorce.
Revocable Living Trusts After Divorce: Amendment, Restatement, or New Trust
A revocable living trust is a legal arrangement that holds assets during the owner's lifetime and passes them to named beneficiaries without probate. During marriage, many San Diego County couples hold nearly everything, the house, the brokerage account, the LLC interests, in a single joint trust. After divorce, that shared vehicle typically gets divided or replaced with a separate trust for each former spouse.
The right to change a revocable trust comes from Cal. Prob. Code § 15401. A trust can be revoked by any method the trust document provides, or by a signed writing delivered to the trustee, unless the document makes its own method exclusive. Where a trust has more than one settlor (the person who creates and funds it), each settlor generally may revoke the portion that settlor contributed, subject to a Family Code rule for community property. The trust instrument and the divorce judgment together shape what each former spouse can do with their share.
There are three common paths:
- Amendment changes specific provisions, such as removing the former spouse as successor trustee. It is narrow and quick, but a trust with many amendments becomes hard to read.
- Restatement replaces the entire trust document while keeping the same trust in existence, often with the same name and date. Assets already titled in the trust usually stay put.
- A new trust creates a new entity. Every asset then has to be retitled into it through new deeds, account re-registrations, and assignments.
High-net-worth trusts add a coordination problem. A trust holding a business interest, an investment portfolio, or San Diego County rental property is only as accurate as the property division it follows. If the judgment awarded one spouse the operating company and the other the commercial building, the trust documents and the actual titles need to match that outcome. More on how trust assets are characterized in the first place appears in our article on trusts in divorce.
Successor trustee choices also change. The former spouse is typically removed. Replacements tend to be an adult child, a trusted individual, or a professional or corporate trustee such as a trust company, particularly where the trust will hold operating businesses or concentrated positions that need active management.
Beneficiary Designations: The Most Commonly Overlooked Step
Beneficiary designations are contracts between the account owner and the institution. Retirement accounts, life insurance, annuities, and transfer-on-death brokerage accounts pass outside the will and outside the trust. The form on file with the plan administrator or insurer controls.
The ERISA point bears repeating because it is where the largest mistakes occur. Under Egelhoff, a 401(k) or employer pension pays the named beneficiary regardless of the divorce. California's nonprobate revocation rules do not override that result. A former spouse named on a 401(k) form in 2012 is still the beneficiary in 2026 unless a new form was submitted. Whether the divorce judgment itself properly divided the plan is a separate question, handled by a qualified domestic relations order and discussed in our guide to pension plans and retirement benefits.
In practice, the cleanup starts with an inventory. A complete list for an executive or business owner often includes:
- 401(k), 403(b), and pension plans
- IRAs and Roth IRAs
- Nonqualified deferred compensation plans
- Equity plans with beneficiary provisions for vested RSUs or options
- Individual and group life insurance
- Annuities
- Health savings accounts
- 529 education plans (which name a successor owner rather than a beneficiary in the usual sense)
- Transfer-on-death and pay-on-death brokerage and bank accounts
Each institution has its own form. Each form has a primary and a contingent line. Updating the primary beneficiary while leaving the former spouse, or a former in-law, as contingent leaves a gap if the primary beneficiary dies first.
Two phrases on those forms deserve a plain explanation. Per stirpes means "by branch": if a named child dies before the account owner, that child's share passes down to that child's own children. Per capita generally divides the gift among those beneficiaries still living, so a deceased child's branch may receive nothing. When the new beneficiaries are children, that choice decides whether grandchildren are protected.
For clients with complex portfolios, designations work best when they are reviewed alongside the trust. Naming the trust as beneficiary, naming individuals directly, or splitting between the two each carries different income tax and control consequences for retirement assets.
Wills After Divorce: What Probate Code § 21386 Does and Does Not Do
A will that names a former spouse keeps working after divorce, just with that person effectively written out. California law generally revokes gifts to the former spouse and the former spouse's nomination as executor, and § 21386, discussed above, supplies the "treated as predeceased" rule. The rest of the will remains valid.
Where the lapsed gift goes follows a set order. Cal. Prob. Code § 21111 provides that a failed transfer goes first to any alternative named in the document, then into the residue, and, if there is no residuary clause, to the decedent's estate. Property that the will does not effectively dispose of then passes to heirs. Cal. Prob. Code § 6400 states that rule directly:
"Any part of the estate of a decedent not effectively disposed of by will passes to the decedent's heirs as prescribed in this part."
The intestate succession rules in Probate Code §§ 6400–6414 then decide who the heirs are. With no surviving spouse, the general order runs to children and their descendants, then parents, then siblings and their descendants.
Even with all of that in place, an old will rarely reflects current wishes. It may name the former spouse as guardian of minor children, a role the automatic rules do not always resolve cleanly. It may predate the business, the RSU grants, or the real estate acquired after the divorce. Its alternate beneficiaries may have been chosen with the marriage in mind.
When a San Diego County resident dies with a will that was never updated, the estate generally moves through the San Diego Superior Court Probate Division. Ambiguity about intent, stale executor nominations, and competing claims from family members are among the conditions that tend to turn a routine probate into a contested one.
Powers of Attorney and Health Care Directives: Replacing Your Former Spouse as Agent
Section 4154 handles the financial power of attorney directly. When the principal's marriage to the attorney-in-fact is dissolved or annulled, that designation is revoked. The statute adds a detail most people never expect: the authority revives if the two later remarry.
Health care directives work along a parallel track. California law generally revokes a former spouse's designation as health care agent after dissolution. Separately, Cal. Prob. Code § 4695 describes how a patient with capacity may revoke an agent designation on their own: "only by a signed writing or by personally informing the supervising health care provider."
Statutory revocation and practical clarity are different things. A bank officer or an emergency room nurse looking at a signed document naming the former spouse may not know about the divorce. A new, dated document removes the question entirely and avoids delay at exactly the moment delay is most costly.
The choice of new agent is personal. For finances, people tend to look for someone with financial literacy and the time to handle it. For health care, the focus usually shifts to someone who knows the principal's values and can make hard decisions under pressure. A HIPAA authorization, either inside the directive or as a separate release, names who may receive medical information at all.
For business owners in San Diego County, the financial power of attorney deserves a closer look. A generic form may not clearly authorize the agent to vote LLC membership interests, sign for a corporation, or deal with buy-sell obligations. Operating agreements and bylaws sometimes restrict who can act for an owner, so business counsel is often part of the conversation.
Timing: When to Update Your Estate Plan During and After the Divorce Process
While the case is pending, automatic temporary restraining orders, called ATROs, apply to both spouses. They are printed on the back of the family law summons and take effect for the petitioner on filing and for the respondent on service. In general terms, they bar transferring, encumbering, hypothecating (pledging as collateral), concealing, or disposing of property without the other spouse's written consent or a court order, outside of usual expenses. They also restrict changing beneficiaries on insurance held for the parties or their children, and they require notice to the other spouse before creating or modifying a nonprobate transfer.
The ATROs are narrower than many people assume in some ways and broader in others. Signing a new will is generally not restricted, because a will does nothing until death. Changes that move or retitle community property, rearrange a joint trust, or alter certain beneficiary designations are another matter. Given how the rules are worded, proposed changes during the case are typically reviewed by counsel against the summons language before anything is signed.
The judgment is the trigger point. Once it is entered by the San Diego Superior Court, the statutory revocations described earlier take effect, and a full estate plan review becomes possible without the ATROs in the way. The date of entry on the judgment, not the date of a hearing or settlement, is the operative date.
After judgment, a common working sequence looks like this:
- Beneficiary designations on retirement accounts and insurance policies
- A new will
- A new durable power of attorney and advance health care directive
- Amendment or restatement of the revocable living trust
- Retitling of real property and financial accounts to match the judgment
The order reflects risk. An ERISA plan keeps paying the former spouse until a new form arrives, so that step tends to come first. In high-asset cases, many clients treat the weeks right after entry of judgment as the window to finish this work, because every month between the judgment and the completed update is a month in which old documents control.
Common Mistakes in Post-Divorce Estate Planning
The same handful of errors show up again and again after San Diego County divorces. None of them is exotic. Each is a gap between two systems that were assumed to be connected.
Leaving the ERISA form alone. This is the single most consequential oversight. The former spouse receives the 401(k) even though the judgment and the will both point elsewhere.
Assuming the divorce decree controls. A judgment divides property between the spouses. It does not, by itself, override a beneficiary form or change joint tenancy title on record. Our list of overlooked assets in divorce covers several related loose ends.
Updating one document and not the others. A new will with an old trust, or a restated trust with old beneficiary forms, produces an estate plan that contradicts itself.
Naming minor children directly. A child under 18 generally cannot receive and manage a significant inheritance outright. Without a trust or a custodianship under the California Uniform Transfers to Minors Act, a court-supervised guardianship of the estate may be needed. Cal. Prob. Code § 3400, which begins the article on a minor's estate, expressly deducts UTMA custodial property when computing the "total estate of the minor," one sign of how a custodianship changes the path.
Leaving fiduciary roles vacant. Removing the former spouse as executor or trustee without naming a replacement hands the choice to the court.
Waiting for the next life event. Remarriage or a new child tends to prompt a review, but the gap before then carries its own risk.
Not coordinating with the divorce judgment. Business interests and San Diego County real estate are where mismatches cost the most. A trust that still lists a property awarded to the other spouse, or a buy-sell agreement that assumes both spouses are owners, creates problems a probate judge later has to untangle. How those assets were divided in the first place is explained in our overview of complex property division.
If You'd Like to Talk Through How Your Judgment and Estate Plan Fit Together
Post-divorce estate planning for a business owner or executive is rarely about one document. It is about whether the judgment, the trust, the titles, and a dozen beneficiary forms all tell the same story. A consultation is the place to walk through the judgment line by line, identify which assets carry ERISA or title issues, and leave with a clear list of which documents need attention and in what order. For readers who need only a simple will with no divorce-related property questions, a general estate planning office may be a more useful first call.
