You found love again. Maybe after a divorce, maybe after losing a spouse. Now you have a home you bought before this marriage, a retirement account you have been contributing to for twenty years, and children from your first marriage who are counting on you. Your new spouse has children of their own. Everyone gets along — for now.
Here is the question nobody wants to ask at the dinner table: when you die, who gets what?
If your answer is “we will figure it out” or “my spouse will do the right thing,” you are not alone. But you are setting your family up for a fight that California’s community property laws will decide for you — and the result may not be what anyone wanted.
I am a Certified Family Law Specialist who practices on the Central Coast, serving families in Santa Barbara County, San Luis Obispo County, and Ventura County. A significant portion of my practice involves what happens when community property law meets estate planning in second marriages. I have seen what happens when families plan well, and I have litigated the cases where they did not. This article is designed to give you a clear, honest overview of the legal landscape so you can make informed decisions.
Why Second Marriage Estate Planning Is Different
First marriages are relatively simple from an estate planning perspective. You build wealth together. You leave it to each other. When the surviving spouse dies, the children inherit.
Second marriages break that model. You are trying to balance obligations to a new spouse with promises — explicit or implicit — that you made to children from a prior relationship. You are mixing assets that were earned decades apart. And you are doing this in California, a community property state with some of the most complex property characterization rules in the country.
Nearly half of all marriages in California involve at least one person who has been married before. That means thousands of blended families across San Luis Obispo, Santa Maria, Paso Robles, Lompoc, Santa Barbara, Ventura, and Oxnard are navigating these exact issues right now.
How California Community Property Law Applies to Second Marriages
Under California Family Code section 760, all property acquired during marriage by either spouse’s labor or effort is presumed to be community property. It does not matter whose name is on the paycheck, the bank account, or even the deed. Once you are married, the law presumes you are building wealth together.
When a married person dies, Probate Code section 100 controls what happens to community property. The surviving spouse already owns their half — that half was never the deceased spouse’s to give away. The decedent can only dispose of their own half through a will or trust. If there is no estate plan, Probate Code section 6401 dictates that the surviving spouse inherits the decedent’s half of the community property outright. The result: the surviving spouse ends up with one hundred percent of everything the couple built together.
For a first marriage, this is usually fine. For a second marriage with children from prior relationships, it can be devastating. Your surviving spouse now owns all of the community property and can leave it to anyone — including their own children, a new partner, or a charity. Your children from your first marriage get nothing from those assets unless your spouse voluntarily provides for them. Good intentions do not survive probate.
Separate Property in a Second Marriage
Separate property follows different rules. Under Family Code section 770, separate property includes assets you owned before the marriage, inheritances received during the marriage, and gifts made specifically to you.
When you die without an estate plan, your separate property does not all go to your surviving spouse. Under Probate Code section 6401, if you have one child, your spouse receives one-half of your separate property and your child receives the other half. If you have two or more children, your spouse receives one-third and your children split the remaining two-thirds.
This is where it gets complicated for blended families. Suppose you own a rental property in Santa Maria worth four hundred thousand dollars that you bought before your second marriage. That is your separate property. You also bought a home with your new spouse worth six hundred thousand dollars and accumulated two hundred thousand dollars in savings from your combined incomes during the marriage — both community property.
You die without a plan.
Your spouse already owned their half of the community property. They inherit your half too. They now own the home and all savings outright. For the rental property — your separate property — if you have two children from your first marriage, your spouse receives roughly one-third and your children split the rest.
Your children just inherited far less than you probably intended. And your spouse now co-owns a rental property with stepchildren. If they do not get along, this becomes a lawsuit.
The Commingling and Transmutation Trap
Separate property can lose its character if you are not careful, and this is one of the most common mistakes I see in second marriages on the Central Coast.
Commingling occurs when you mix separate property funds with community property funds in a way that makes them impossible to trace. Deposit your separate property inheritance into a joint checking account that you use to pay household bills, and you may have just made it untraceable — and therefore community property.
Transmutation is a related but distinct concept governed by Family Code sections 850 through 852. If you add your new spouse’s name to the deed of your separate property house, or sign a document that changes the character of an asset from separate to community, that may constitute a transmutation. Under California law, a transmutation of real or personal property requires a writing that contains an express declaration that the property is being changed in character. This is a strict requirement — the California Supreme Court has enforced it rigorously.
The practical takeaway: do not add your new spouse to titles, deeds, or accounts without understanding the legal consequences. What feels like a gesture of trust can unintentionally disinherit your children.
Quasi-Community Property
If you and your spouse lived in another state before moving to California, you should know about quasi-community property. Under Probate Code section 101, property acquired while living in a non-community property state that would have been community property had you lived in California at the time is treated as quasi-community property. When you die in California, quasi-community property is divided the same way as regular community property.
This catches many people off guard, particularly retirees who move to the Central Coast from states like New York, Illinois, or Florida.
Prenuptial and Postnuptial Agreements as Estate Planning Tools
Most people think of prenuptial agreements as divorce planning. They are that, but in a second marriage, a prenup is just as much an estate planning tool. A well-drafted prenuptial agreement lets you define in advance which assets will remain separate property and which will be community property — and that characterization controls what happens at death.
California prenuptial agreements are governed by the Uniform Premarital Agreement Act, codified in Family Code sections 1610 through 1617. To be enforceable, a prenup must be in writing, signed before the marriage, entered into voluntarily, not unconscionable, and accompanied by full financial disclosure. Under Family Code section 1615, the party against whom enforcement is sought must have been represented by independent counsel or must have expressly waived that right in a separate writing — and the agreement must have been presented at least seven days before signing.
A prenup can specify that the business you built before marriage will always remain your separate property, even if it appreciates in value during the marriage. It can provide that your spouse waives any claim to your separate property at death, allowing you to leave it entirely to your children.
But here is where coordination becomes critical: your prenup and your estate planning documents must say the same thing. If your prenup says your spouse waives all rights to your separate property, but your life insurance beneficiary designation still names your spouse, the insurance company pays according to the beneficiary form — not the prenup. Beneficiary designations override everything.
If you did not sign a prenup before the wedding, a postnuptial agreement can accomplish many of the same goals. California law permits married couples to agree in writing to change the character of their property. But postnuptial agreements receive even greater scrutiny from courts because of the fiduciary duties spouses owe each other under Family Code section 721 — the duty of highest good faith and fair dealing.
Trust-Based Planning for Blended Families
For most families in second marriages, a revocable living trust is the foundation of the estate plan. A trust lets you avoid probate, maintain control during your lifetime, and specify exactly who receives what after you die.
The QTIP Trust: Protecting Both Sides
The Qualified Terminable Interest Property trust — the QTIP trust — is the workhorse of second marriage estate planning. It solves the central dilemma: how do you provide for your current spouse while guaranteeing that your children from a prior marriage ultimately inherit?
When you die, assets pass into the QTIP trust. Your surviving spouse receives all income generated by the trust during their lifetime and may receive distributions of principal for health, education, maintenance, and support. But your spouse cannot change who inherits the assets after they die. When your spouse passes away, whatever remains in the trust goes to the beneficiaries you named — typically your children from your first marriage.
A Central Coast example: David in Paso Robles remarried at fifty-eight. He has three adult children from his first marriage and wants to ensure they inherit his eight hundred thousand dollar investment portfolio. His trust includes a QTIP provision. When he dies, the portfolio goes into the QTIP trust. His wife receives the income it generates for the rest of her life. She can receive principal if she needs it for medical care or living expenses. But she cannot redirect the assets to her own children or to a new spouse if she remarries. When she dies, David’s three children receive whatever remains.
David’s wife is provided for. David’s children are protected. Neither side can cut out the other.
Separate Subtrust Structures
Another approach creates separate subtrusts at the first death. Your half of the community property funds a trust for your children. Your spouse’s half funds a trust they control. Separate property goes directly to whichever beneficiaries you designate. This structure draws clean lines between “mine,” “yours,” and “ours” — and prevents the surviving spouse from redirecting the deceased spouse’s share.
The Independent Trustee
When tensions exist between a surviving spouse and children from a prior marriage — and they often do — naming an independent trustee or co-trustee can prevent conflicts. A neutral third party makes distribution decisions based on the trust terms, not family politics. This is particularly important for QTIP trusts, where the surviving spouse’s interests and the remainder beneficiaries’ interests are inherently in tension.
I have litigated cases where a surviving spouse who served as sole trustee systematically depleted trust assets that were supposed to pass to the deceased spouse’s children. An independent trustee prevents that.
Beneficiary Designations: The Estate Plan Override
Beneficiary designations on retirement accounts, life insurance policies, and payable-on-death accounts override your will and trust. This is the single most common way estate plans fail in second marriages.
It does not matter what your trust says if your IRA beneficiary form names your ex-spouse. The IRA custodian pays according to their form, period.
After remarriage, review and update every beneficiary designation: 401(k) and IRA accounts, life insurance policies, payable-on-death bank accounts, transfer-on-death brokerage accounts, and annuities.
One critical note about ERISA: if your retirement plan is governed by federal ERISA law — and most employer-sponsored 401(k) plans and pensions are — your current spouse has special protections. Under ERISA, your spouse must consent in writing, with the consent witnessed by a notary or plan representative, before you can name anyone else as primary beneficiary. This spousal consent requirement exists under federal law and generally preempts California community property claims. The United States Supreme Court addressed this directly in Boggs v. Boggs (1997) 520 U.S. 833, holding that ERISA preempts state community property law with respect to covered retirement plans. IRAs are generally not governed by ERISA and are not subject to the same spousal consent requirement.
The Omitted Spouse Problem
Under Probate Code section 21610, if you created your estate plan before your current marriage and did not provide for your new spouse, they may be entitled to an “omitted spouse” share — essentially what they would have received under intestacy law. This can significantly disrupt a plan that was designed to provide for children from a prior marriage.
The solution is straightforward: update your estate plan after remarriage. Even if you intend to leave nothing to your new spouse — which requires a valid prenuptial or postnuptial agreement — your estate planning documents should explicitly state that the omission is intentional, not an oversight.
Stepchildren and Inheritance
California law draws a firm line between biological or legally adopted children and stepchildren. Under intestate succession, stepchildren inherit nothing from a stepparent who dies without a will or trust. Nothing.
There is a narrow exception under Probate Code section 6454: stepchildren may inherit if they can prove the relationship began while the stepchild was a minor, continued throughout both lifetimes, and clear and convincing evidence shows the stepparent would have adopted the child but was legally prevented from doing so. This exception is difficult to establish and rarely succeeds.
If you want to provide for your stepchildren, name them specifically in your trust or will. Do not rely on the phrase “my children” — California courts interpret that to mean biological and legally adopted children only.
If you do not intend to provide for stepchildren, say so explicitly: “I have intentionally made no provision for my spouse’s children from a prior relationship.” This prevents later claims that you overlooked them.
What to Do Now
If you are in a second marriage on the Central Coast — whether you live in San Luis Obispo, Santa Barbara, Santa Maria, Paso Robles, Lompoc, Ventura, Oxnard, or anywhere in between — and you have not addressed estate planning, you are leaving these decisions to the Probate Code. The Probate Code does not know your family. It does not care about your promises. It applies a formula.
The most important step is also the simplest: take action. Review your existing documents. Update beneficiary designations. Talk to your spouse about what you both want and what you have each promised your children.
At Egan Law, I work with blended families across San Luis Obispo County, Santa Barbara County, and Ventura County to create estate plans that protect both sides of the family — plans that are legally sound and that reflect the actual wishes of the people who made them. I also handle the litigation when plans fail or were never made. That perspective — knowing what goes wrong and why — informs every estate plan I help create.

Frequently Asked Questions
Does my new spouse automatically inherit everything when I die?
No. Your spouse already owns their half of the community property — that is theirs, not inherited. They inherit your half of the community property only if your will or trust directs it to them, or if you die without an estate plan. For separate property, your spouse receives between one-third and one-half depending on how many children survive you, unless your estate planning documents provide otherwise.
Can I disinherit my current spouse to protect my children?
California makes complete disinheritance of a spouse extremely difficult. Your spouse already owns half of the community property outright. For your half and your separate property, you can direct those assets elsewhere, but practically speaking, this requires either a prenuptial agreement in which your spouse waived inheritance rights, or trust structures like a QTIP that provide for your spouse during their lifetime while preserving the principal for your children.
What happens if my new spouse and I both have children from previous marriages?
You each control your own separate property and can leave it to your own children. For community property, you each control your half. Many couples in this situation create what practitioners call “his, hers, and ours” trust structures: your separate property goes to your children, your spouse’s separate property goes to theirs, and you make joint decisions about how to allocate community property — often splitting it between both sets of children or using QTIP provisions to provide for the surviving spouse first.
Do I need my spouse’s permission to change my estate plan?
You can revise provisions about your separate property and your half of community property without your spouse’s consent. However, joint trusts and agreements about how community property will be divided require both spouses. Prenuptial and postnuptial agreements are contracts and require the agreement of both parties.
How do California’s community property laws apply if we lived in another state before moving to the Central Coast?
California treats property acquired during marriage in another state as quasi-community property under Probate Code section 101, if it would have been community property had you been living in California at the time. This means property you bought while living in a common-law property state like New York or Florida may still be divided under California community property rules when you die. Assets owned before any marriage, or received by gift or inheritance, generally remain separate property regardless of where you lived when you acquired them.
Should I adopt my stepchildren for estate planning purposes?
Adoption gives stepchildren identical inheritance rights to biological children, but it is a permanent legal change with consequences beyond estate planning. Adoption terminates the legal parent-child relationship with the biological parent, which can affect child support obligations, the biological parent’s estate plan, and family relationships. Most families achieve their estate planning goals by naming stepchildren specifically as beneficiaries in their trust or will rather than pursuing adoption.
What if my ex-spouse is still named on my life insurance or retirement account?
The beneficiary designation controls, regardless of what your will or trust says. If you have not updated your beneficiary forms since your divorce, your ex-spouse will receive those benefits — even if you have been remarried for a decade and your trust says everything goes to your current spouse. Update all beneficiary designations immediately after remarriage. For ERISA-governed plans, remember that your current spouse must sign a written consent before you can name someone else as primary beneficiary.
Can my surviving spouse change my trust after I die?
If you created a joint revocable trust, the surviving spouse typically can modify provisions about their own property but cannot change the provisions you made about yours. QTIP trusts and irrevocable subtrust structures specifically prevent the surviving spouse from redirecting assets or changing beneficiaries. Clear trust drafting and an independent trustee provide the strongest protection.
