Mom Died Without a Will in California: Who Inherits

When your mother dies without a will in California, her estate passes under the state's intestate succession statute. The law prescribes a fixed order: surviving spouse and children first, then parents and siblings if no spouse or children survive. Most of the time, probate court proceedings are required to transfer title, settle debts, and distribute what remains. The process is not automatic, and the family must act.

Who inherits when your mother dies without a will?

California's intestate succession rules depend on which relatives survive. If your mother was married, her spouse inherits all community property outright. Separate property is divided: the spouse receives one-half if one child survives, one-third if two or more children survive, and children split the balance equally. If your mother was unmarried or widowed, her children inherit everything in equal shares. If a child predeceased her but left children of their own, those grandchildren inherit their parent's share by right of representation.

If your mother had no surviving spouse or children, the estate moves up and sideways: to her parents if living, then to her siblings, then to more distant relatives in a statutory cascade. The intestate succession page walks through each tier. Estrangement, need, and caregiving do not alter the formula; the statute treats all children identically.

When a California resident dies without a will as of August 2026, intestate succession law (Probate Code sections 6400–6402) determines heirs in a fixed order: surviving spouse and children first, then parents, siblings, and more distant relatives. Community property passes entirely to the surviving spouse; separate property is divided between spouse and children according to a statutory fraction. Probate is usually required to transfer real property and financial accounts, and the court appoints an administrator to collect assets, pay debts, and distribute the balance. This rule does not cover assets with named beneficiaries, joint tenancy property, or assets held in a living trust, which pass outside probate regardless of whether a will exists.

What happens to the house, bank accounts, and personal property?

Real estate, bank accounts in your mother's sole name, and personal property all form part of the probate estate. The court appoints an administrator—often the surviving spouse or an adult child—who takes legal control, inventories assets, notifies creditors, pays valid claims and taxes, and eventually distributes what remains to the heirs. The administrator has the same fiduciary duties as an executor under a will, but no testamentary roadmap; the intestacy statute supplies the distribution plan.

Some assets bypass probate entirely: life insurance with a named beneficiary, retirement accounts with a designated beneficiary, real property held in joint tenancy, and any assets in a revocable living trust. If your mother held a bank account as joint tenant with right of survivorship, the surviving account holder owns it outright. Transfer-on-death deeds and payable-on-death registrations also avoid probate. The probate administration page explains what falls inside and outside the estate.

Do you have to open probate if mom died without a will?

In most cases, yes. Probate is the only mechanism that gives the administrator legal authority to sell real estate, access solely owned accounts, and deliver clear title to heirs. California does offer shortcuts for small estates: if the total value of property subject to probate falls below the statutory threshold, heirs may use a small estate affidavit to collect assets without full court proceedings. If the only significant asset is real property and the estate otherwise qualifies, a succession to real property petition can transfer title in a simplified hearing.

Even when probate is required, the process is predictable. The family files a petition for probate in the county where your mother lived, the court holds a hearing, and Letters of Administration issue. Creditors receive notice and have a claims period; the administrator files an inventory and, eventually, a final accounting. The probate timeline and probate costs and fees pages detail each stage and the expenses involved.

What if siblings disagree about who should be administrator or how to divide property?

The intestacy statute sets the priority for appointment: surviving spouse first, then children, then other heirs in descending order. If two children both petition, the court considers factors such as residence in California, nomination by other heirs, and absence of conflicts of interest. Once appointed, the administrator owes equal duties to all heirs and must follow the statutory distribution formula; personal preferences do not override the law.

Disputes often arise over whether to sell the family home, the value of personal property, or the administrator's fees. Heirs have the right to object to the inventory, to demand a formal accounting, and to petition for removal if the administrator breaches fiduciary duty. The probate litigation page covers the tools available when conflict hardens. Mediation and settlement are common before a contested hearing; most families resolve differences without trial, but the court has jurisdiction to decide any question of administration or distribution.

What are the first steps after your mother's death?

Secure the residence and valuable personal property, notify financial institutions of the death (but do not withdraw funds), and gather documents: deed, bank statements, tax returns, insurance policies, and any prior wills or trust papers, even if you believe none exist. Sometimes a will surfaces weeks later in a safe-deposit box or attorney's file; if that happens, the intestacy analysis stops and the will governs instead. Confirm whether your mother created a living trust; many Californians execute both a will and a trust, and if the trust was funded, much of the estate may already be outside probate.

Next, consult the county probate court's local rules and consider whether the estate qualifies for a small-estate procedure. If full probate is necessary, one family member—usually the person in possession of the assets or the one who lived closest—files the petition and serves notice on all heirs. The court sets a hearing date, typically six to ten weeks out. In the meantime, routine bills (mortgage, utilities, insurance) should be paid from estate funds if possible, and perishable assets protected. The executor duties page, though written for executors, describes the same responsibilities an administrator carries.
