The Short Answer

Without a plan, incapacity can freeze a business. Payroll may stop, contracts may go unsigned, banking access may be questioned, and important decisions may wait while the family petitions a court for authority. Meanwhile, customers, employees, lenders, and business partners may lose confidence.

The solution is a coordinated incapacity plan prepared while the owner is healthy. That plan typically includes a durable power of attorney with express business authority, a trust that names a capable successor trustee, an operating agreement or buy-sell agreement addressing incapacity, and a clear succession bench. Health-care documents must also be coordinated so the right people can obtain information and make medical decisions. The goal is simple: keep the business operating while protecting ownership value and family stability.

Who This Applies To

This issue matters to:

• California business owners and entrepreneurs
• Owners of closely held corporations and LLCs
• Professional practice owners, including physicians, dentists, attorneys, and consultants
• Business partners and co-managers
• Families who depend on business income
• Owners whose value is concentrated in one company

Incapacity is not merely a family event. It is a business-continuity event. A stroke, serious accident, cognitive decline, or unexpected medical emergency can create an immediate authority problem even when the business itself remains profitable.

The Three Decisions Your Plan Must Coordinate

A reliable business-continuity plan answers three separate questions.

Who can manage the business day to day?

A properly drafted durable power of attorney may authorize an agent to handle banking, payroll, contracts, taxes, leases, employees, and other business matters. Under California Probate Code § 4120, the principal must have capacity to contract when signing the power of attorney. Under § 4124, the document must contain language showing that the authority continues despite later incapacity, or that it becomes effective upon incapacity.

The document should also state whether authority is effective immediately or only after a defined triggering event. A “springing” power of attorney may create a delay if the incapacity standard is unclear or difficult to document. Banks and counterparties may also require specific authority in the document before accepting an agent's instructions.

Under Probate Code § 4125, acts taken by an agent under a durable power of attorney during the principal's incapacity may bind the principal and successors in interest as though the principal had capacity.

Who owns and controls the value?

If an ownership interest is held in a revocable trust, the successor trustee may manage that trust asset according to the trust terms. The trust should address the successor trustee's authority to hold, vote, manage, sell, or otherwise deal with the business interest.

That does not automatically make the successor trustee the company's day-to-day manager. The trust, stock records, operating agreement, bylaws, and other entity documents must work together.

Who handles health decisions?

An advance health care directive under Probate Code § 4701 can name a health-care agent and provide instructions about medical decisions. HIPAA authorizations can help designated people receive medical information needed to understand the owner's condition and apply the incapacity standard.

Do not treat health-care authority and business authority as interchangeable. They are different legal functions and should be documented separately.

What the Governing Documents Actually Do

Hypothetical Only: How These Problems Unfold

The sole practitioner after a stroke

A physician owns a professional practice personally and signs a general power of attorney that does not clearly address business operations. After a stroke, the physician's spouse knows the payroll deadlines and office vendors, but cannot automatically sign contracts, access every account, or make decisions reserved to the owner.

If no valid authority exists, the family may need to seek a conservatorship of the estate under Probate Code §§ 1800 et seq. That process can take time the practice does not have.

The partner whose operating agreement is silent

Two owners operate a successful California company. One becomes incapacitated. The operating agreement explains what happens at death but says nothing about temporary incapacity. The remaining partner wants to keep the company running, but cannot assume that the incapacitated partner's voting, transfer, or approval rights disappear.

A buy-sell or disability provision could have defined the process, valuation method, payment terms, and management authority. Without it, the owners may face a dispute when they most need cooperation.

The trust that was never updated

An owner has a revocable trust, but the named successor trustee is an elderly relative who knows nothing about the company. The operating agreement requires approval for transfers and the business interest was never properly assigned to the trust.

The existence of a trust alone does not solve the problem. Review the trust funding, successor trustee, entity records, and operating agreement together.

Common Mistakes

• Assuming a spouse can simply step in. Marriage does not automatically give a spouse authority over a separate business or every entity decision.
• Signing a power of attorney without express business-management powers.
• Ignoring the operating agreement's consent, transfer, voting, and manager-replacement provisions.
• Naming a successor trustee who lacks the judgment, availability, or knowledge to manage a business interest.
• Waiting until incapacity occurs. A power of attorney generally must be executed while the owner has the required capacity.
• Failing to coordinate a buy-sell agreement with the estate plan, trust, insurance, tax planning, and family objectives.
• Naming a health-care agent but never authorizing the right people to obtain medical information.
• Assuming a document prepared years ago still reflects the current ownership structure.

A Practical Review Checklist

Start with the documents, then test how they work in the real world:

1. Identify the business entity and locate its current governing documents.
2. Confirm who has authority to sign contracts, access accounts, approve payroll, and make management decisions today.
3. Review or prepare a durable power of attorney with specific business powers.
4. Confirm whether the trust owns the business interest and whether the successor trustee is appropriate.
5. Review the operating agreement, bylaws, shareholder agreement, and buy-sell provisions for incapacity.
6. Name a health-care agent and appropriate HIPAA designees.
7. Brief the successor team on where records are kept, who the key advisers are, and what decisions require immediate attention.

Tactical FAQ

Can my spouse run my business if I become incapacitated?

Not automatically. A spouse may have certain rights depending on the ownership structure and whether property is community property, but marriage alone does not provide complete authority over a separate business, an LLC membership interest, corporate voting rights, or business bank accounts.

Use a durable power of attorney, trust provisions, and entity documents that identify who may act. If you want a broader baseline on how trusts and incapacity planning fit together, review the firm's estate planning living trust FAQs.

What does a durable power of attorney need to include for business?

It should address the authority needed for the actual business. Depending on the company, that may include banking, payroll, contracts, tax matters, employees, leases, litigation, borrowing, real estate, ownership interests, and communications with advisers.

The document should also clearly state when it becomes effective and whether the agent may exercise voting or management rights. General language may not be enough for a bank, lender, customer, or business partner.

What happens if there is no plan?

The family may need to petition for a conservatorship of the estate under California Probate Code §§ 1800 et seq. A court may then determine who can manage the owner's financial affairs and business interests.

That process can be expensive, public, and slower than the business's operational needs. It also places important decisions in a court-supervised process rather than with a team selected by the owner.

Can my partner buy my interest if I'm incapacitated?

Only if the governing documents provide a workable mechanism or the parties reach another legally effective agreement. A buy-sell agreement may address disability or incapacity, but review its definition, waiting period, valuation method, funding, payment terms, and voting provisions.

Do not assume a death provision automatically applies to incapacity.

What is a conservatorship, and why do business owners try to avoid it?

A conservatorship is a court proceeding used when an adult cannot manage personal or financial affairs. A conservator of the estate may receive authority to manage property and financial matters, subject to court supervision.

Conservatorship can be necessary in some situations. Business owners often plan ahead because court involvement may delay decisions, increase costs, expose sensitive information, and place business continuity in the hands of a process the owner did not design.

What Remains Fact-Specific

The right structure depends on the entity type, ownership records, operating agreement, trust terms, power-of-attorney language, nature of the business, regulatory requirements, family dynamics, and the capabilities of the proposed successor.

Evaluate Your Business-Continuity Readiness

Request a Situation Readiness Briefing as a focused business-continuity diagnostic. Bring the entity documents, trust documents, operating agreement, buy-sell agreement, and current powers of attorney.

The objective is to identify who can act, what authority is missing, and where the business could lose time or value if you cannot make decisions. For additional preparation, the firm's planning command resource can help you assemble the relevant records before the briefing.
