Key Takeaways

• What happens to a business at the owner’s death depends heavily on its structure — sole proprietorship, partnership, LLC, or corporation.
• A personal representative can sometimes keep operating the business during probate, but generally needs court authorization to continue it beyond a short period.
• For entities, the deceased owner’s interest passes through the estate, but management rights may not pass automatically — and a buy-sell agreement can override the default rules.
• A sole proprietorship’s assets become estate assets directly; an entity interest passes as the owner’s ownership stake.
• These are complex, often time-sensitive matters where the wrong move can damage the business’s value.

Why Structure Drives Everything

When a business owner dies, the most important question isn’t “what happens to the business?” in the abstract — it’s “how was the business organized?” A sole proprietorship, a partnership, an LLC, and a corporation each lead to very different outcomes for control, continuation, and transfer. The structure determines whether the business is part of the probate estate directly, whether it can keep running, who gets to make decisions, and how the owner’s stake passes to heirs.

This is also one of the most time-sensitive areas of probate. A business can lose value quickly if it’s left in limbo — employees leave, customers go elsewhere, opportunities are missed. So the family and the personal representative often have to act faster here than in an ordinary estate, while still following the rules. Getting it wrong can permanently damage what may be the estate’s most valuable asset.

Sole Proprietorship

A sole proprietorship isn’t a separate legal entity — it’s just the owner doing business in their own name. So when the owner dies, the business’s assets become estate assets directly. There’s no company that survives the owner; there’s a collection of assets (equipment, inventory, accounts, goodwill, contracts) that now belong to the estate and have to be administered like any other property.

The personal representative steps into managing those assets, which raises the immediate question of whether the business can keep operating while the estate is administered — addressed below. Often a sole proprietorship is wound down or sold rather than continued, because without the owner, much of its value may depend on what can be transferred.

Partnerships

In a partnership, a partner’s death is typically an event that triggers consequences under California partnership law and the partnership agreement. Commonly, the deceased partner’s death causes their dissociation from the partnership, and what happens next — whether the partnership continues with the remaining partners and buys out the deceased partner’s interest, or winds up — depends on the partnership agreement and the law.

Usually the deceased partner’s economic interest (their right to their share of value) passes to their estate, while the remaining partners continue the business and the estate is bought out according to the agreement. A well-drafted partnership agreement usually spells this out; without one, the default rules govern, which can be messier. The estate’s job is often to collect the value of the deceased partner’s interest rather than to step into running the partnership.

LLCs

For a limited liability company, California law draws a crucial distinction: when a member dies, their transferable (economic) interest — the right to distributions and value — generally passes to their estate and heirs. But the management and membership rights — the right to participate in running the LLC, vote, and make decisions — do not automatically pass with it. Those rights depend on the operating agreement and the consent of the other members.

So an heir who inherits a deceased member’s LLC interest may end up with the economic benefit (a share of profits and value) without the control (a say in operations) unless the operating agreement provides otherwise or the other members agree. For a single-member LLC, special rules can allow the membership to pass to the heirs so the LLC continues. This split between economic rights and management rights surprises families and is a frequent source of dispute — and it’s heavily governed by the operating agreement, which should be reviewed early.

Corporations

For a corporation, the deceased owner’s shares are personal property that pass through the estate like other assets. The corporation itself continues to exist — it doesn’t dissolve because a shareholder died — and its board and officers keep running it. The estate’s role is to administer and transfer the shares. In a small, closely held corporation, the practical control questions can resemble those of an LLC or partnership, and again a shareholder or buy-sell agreement frequently governs what happens to a deceased owner’s shares.

A business in an estate is often the most valuable — and most fragile — asset. The rules turn on the entity type and the governing agreements. Bay Legal can help you handle it correctly.

Can the Representative Keep the Business Running?

A pressing practical question: can the personal representative keep operating the business while probate plays out? California law allows a representative to continue operating a decedent’s (unincorporated) business for a limited period, but generally requires court authorization to continue it beyond that short window. The court can authorize continued operation when it’s in the estate’s interest, with appropriate oversight.

This matters because a business often can’t simply pause. The representative may need to keep employees paid, fulfill contracts, and maintain operations to preserve value — but doing so carries fiduciary risk, since the representative can be personally liable for mismanaging the business. Getting court authorization and clear authority is the protective path. (Partnerships and corporations follow their own rules, since those entities continue under their remaining partners or officers.)

The Role of Buy-Sell and Governing Agreements

Across partnerships, LLCs, and closely held corporations, one document often controls the outcome more than the default law: the buy-sell agreement (or the partnership/operating/shareholder agreement). These agreements commonly specify what happens to an owner’s interest at death — for example, that the surviving owners or the entity will buy out the deceased owner’s interest at a set price or formula, often funded by life insurance. A valid agreement generally supersedes the default statutory rules.

So when a business owner dies, an early and essential step is finding and reviewing these agreements. They can answer most of the key questions — who gets control, how the estate is paid for the interest, on what timeline — and they often prevent the disputes that arise when there’s no agreement and the default rules leave things unclear.

Find the governing agreements first — they often control what happens to the business. Bay Legal can help you locate, interpret, and act on them. For guidance on your specific situation, call (650) 668-8000 or schedule a consultation at baylegal.com/contact.

A Note on Taxes and Valuation

A business interest has to be valued for the estate (an independent expert is often used), and there can be significant tax considerations — estate tax for large estates, special valuation and payment rules for closely held businesses, and income-tax issues. These are tax matters for a CPA or tax professional; the firm does not give tax advice. What a probate attorney handles is the legal side — the authority to operate, the transfer of the interest, the governing agreements — coordinated with the tax professionals on the valuation and tax pieces.

How This Fits With the Rest of Probate

A business interest is administered within the broader probate process, valued as part of the inventory and appraisal, and ultimately transferred in distribution. Continuing to operate it relies on the representative’s authority. For pre-death planning to avoid these problems, a buy-sell agreement and trust planning matter. For the full process, see our complete guide to California probate.

Frequently Asked Questions

What happens to a business when the owner dies in California?

It depends on the structure. A sole proprietorship’s assets become estate assets directly. A partnership, LLC, or corporation interest passes through the estate, but control and continuation depend on the entity rules and any governing agreement like a buy-sell.

Can an executor keep running a business during probate?

For an unincorporated business, the representative can operate it for a limited period but generally needs court authorization to continue beyond that. The court can authorize continued operation when it serves the estate, with oversight.

What happens to an LLC when a member dies in California?

The member’s economic interest generally passes to their estate and heirs, but management and membership rights don’t automatically pass — those depend on the operating agreement and the other members’ consent. Heirs may get the economic benefit without control.

Does a buy-sell agreement control what happens to the business?

Usually yes. A valid buy-sell (or partnership, operating, or shareholder) agreement generally supersedes the default rules, often providing that surviving owners or the entity buy out the deceased owner’s interest on set terms.

Does a business have to go through probate?

A business interest held in the deceased owner’s individual name generally does, unless it was held in a trust or passes under a governing agreement. Planning ahead with a trust or buy-sell agreement can change that.
