Beyond the Handshake: 5 Surprising Truths About Protecting Your Business and Legacy

Why a Handshake Stops Working on the Worst Day

A handshake agreement works for exactly as long as both people who shook hands are alive and still on speaking terms. It depends on memory. When one of them dies, the memory that held the deal together goes with him, and what is left is a spouse, a set of adult children, a trustee and a surviving partner, each holding a slightly different version of what was promised.

None of them is lying. That is what makes it hard.

The surviving partner remembers that the two of them agreed whoever outlived the other would buy out the family at book value. The widow remembers her husband saying the building was "half ours, always." The children found a 2009 email that suggests a third arrangement entirely. The trustee, meanwhile, is holding a file that agrees with none of them. Each version is plausible, and none of them is signed.

From the real estate side, the practical consequence is delay. A title company will not insure a sale when it cannot tell who has authority to sign. A buyer's lender will not fund on a building whose ownership is in dispute. Every month the question stays open, the property taxes and insurance keep running, and the relationship between the families keeps getting worse.

Truth 1: California May Already Consider You Partners

Many owners assume that because they never signed a partnership agreement, they do not have a partnership. California law does not work that way. Under Corporations Code section 16202, the association of two or more persons to carry on as co-owners a business for profit forms a partnership, whether or not the persons intend to form a partnership[2].

Read that last clause twice. Intent is not the test.

So the two friends may have formed a general partnership the day they started splitting profits, and everything they did afterwards was done inside a legal structure they never chose and never documented. When there is no written agreement, the default rules in the statute fill the gaps, and the default rules were written for nobody in particular. They were certainly not written with your family in mind.

Why this matters for real estate

If the partnership bought a building, the questions multiply. Is the building partnership property, or does it belong to the two individuals as co-owners who happen to lease it to their business? The answer often depends on how the deed was taken and whose money went into the down payment. I have seen a single building reported one way on a personal tax return and another way on a partnership return. Untangling it took the attorneys months.

My opinion, for what it is worth after two decades of watching this: if you are in business with someone and you do not have a written agreement, the first protective step is not a trust or an LLC. It is a two hour meeting with a business attorney to decide what you already are, and then to write it down.

Truth 2: A Partner's Death Changes the Business Immediately

Families expect the legal consequences of a death to arrive slowly, after the funeral, after the attorney is hired. In a partnership, one of them arrives at once. Corporations Code section 16601 lists the events that cause a partner to be dissociated from a partnership, and for an individual partner the list includes the partner's death[3]. The same section also lists the appointment of a guardian or conservator, and a court finding of incapacity[3].

That second part is the one owners overlook. A partner does not have to die for the partnership to lose him. A conservatorship can do it too.

What happens after dissociation (whether the business continues, and how the departing partner's interest is valued and paid) is governed by the partnership agreement and by other sections of the statute. With a good agreement, the answer is already written and everyone follows it. Without one, the families find out what the default rules say at the same moment they are grieving, and the surviving partner and the estate are suddenly on opposite sides of a valuation.

If the business is an LLC

Forming an LLC helps, but it does not hand your seat at the table to your children. Under Corporations Code section 17705.04, when a member dies, the member's personal representative may exercise the rights of a transferee, and, for the purpose of settling the estate, the rights of a current member under section 17704.10[4]. That is a narrower set of rights than the member had in life. Whether your heirs can step into management is a question the operating agreement should answer, and many off the shelf operating agreements answer it badly or not at all.

I have seen this play out in the real estate. An LLC owns a fourplex in Costa Mesa. The managing member dies, and the remaining member and the estate cannot agree on whether to sell. The operating agreement is silent. The property sits.

Truth 3: Real Estate Deals Have to Be in Writing

California's statute of frauds, Civil Code section 1624, lists contracts that are invalid unless they, or a note or memorandum of them, are in writing and signed by the party to be charged. Several of them sit right at the center of a family business that owns property[1]:

• An agreement for the sale of real property, or for a lease of real property longer than one year[1].
• An agreement that by its terms is not to be performed within a year from the making of it[1].
• An agreement authorizing or employing an agent or broker to purchase or sell real estate for compensation or a commission[1].
• When an agent signs an agreement for the sale or long lease of real property on someone else's behalf, the agent's authority must itself be in writing, signed by the party being bound[1].

Now run your handshake through that list. "If I die first, you buy my half of the building" is an agreement about the sale of real property. "The business can stay in the building as long as it wants at the old rent" is a lease for longer than one year. Both are exactly the kind of promise the statute was written to keep from being enforced on someone's word alone.

There are exceptions and doctrines that courts apply in hard cases, and your attorney will know them. I would not build a family's future on the hope that a judge applies one.

The lease nobody signed

The most common version I see is a business that has occupied a building owned by the founder personally, or by the founder's trust, for twenty years with no written lease. When the founder dies, the trustee owes duties to the beneficiaries, and those beneficiaries may not include the people running the business. A trustee who lets the company stay at a below market rent because "that was Dad's wish" may be inviting a dispute. A trustee who raises the rent may be putting the family business under. A written lease, signed while the founder was alive, would have settled it.

Truth 4: Moving Property Into an Entity Can Trigger Reassessment Later

Owners hear that they should put their buildings into an LLC, and often that is good advice. What they rarely hear is how the property tax rules treat entity interests over time, and for a building bought decades ago in Irvine or Newport Beach, the property tax base is often the most valuable thing about it.

Revenue and Taxation Code section 64 starts with a general rule: the purchase or transfer of ownership interests in legal entities is not treated as a transfer of the real property the entity owns[5]. Two exceptions do most of the damage.

1. Change in control. When a person or entity obtains control through direct or indirect ownership of more than 50 percent of the interests, the transfer is a change of ownership of the entity's real property[5].
2. Original co-owners. When property was moved into an entity under the proportional interest exclusion in section 62(a)(2), the people who held interests immediately afterward are treated as original co-owners. Once those original co-owners transfer, cumulatively, more than 50 percent of the total interests, the property owned by the entity is reappraised[5].

The word "cumulatively" is the trap. A gift of 10 percent to a daughter this year, then a sale of 15 percent to a key employee in three years: each step looks small, but the statute adds them up, and nobody receives a bill in the mail warning that the line is close.

My view: every family entity that owns California real estate should keep a simple written ledger of every interest transfer since the property went in, with dates and percentages. It costs nothing. The families who did not keep one end up reconstructing it from old tax returns.

Truth 5: Prop 19 Protects the Family Home, Not Your Company's Building

Since February 16, 2021, the parent-child exclusion under Proposition 19 has applied to a family home that was the parent's principal residence and becomes the child's principal residence, or to a family farm[6]. A rental home transferred between parent and child does not qualify[6]. The Board of Equalization describes only those two categories, the family home and the family farm. The warehouse in Fullerton that your company has occupied since 1994 is neither.

Owners who remember the old Proposition 58 rules are often caught off guard here, because Prop 58 treated a broader range of property differently. Transfers on or before February 15, 2021 still fall under Proposition 58[6]. Everything after that date is under the new rules.

Even for the family home, the exclusion has a ceiling. The child keeps the parent's factored base year value only up to that value plus an adjusted amount, which is $1,044,586 for transfers from February 16, 2025 through February 15, 2027[6]. Market value above the limit is added to the base. The child also has to file for the homeowners' exemption, and the BOE says that claim must be filed within one year of the date of death or transfer for the exclusion to apply from the start[6].

I wrote a longer explanation of these rules in Proposition 19 Explained. For a business owner, the short version is uncomfortable: plan on the business real estate being reassessed when it passes to the next generation, unless your attorney finds a structure that legitimately avoids it, and run the numbers on what the new tax bill does to the business's cash flow.

Protecting Your Business and Legacy From the Federal Estate Tax

For most families I work with, the federal estate tax is not the problem. For some business owners, especially those holding several Orange County buildings bought long ago, it can be.

The IRS lists a basic exclusion amount of $13,990,000 for people who died in 2025, and $15,000,000 for 2026[7]. The IRS attributes the 2026 increase to Public Law 119-21, signed on July 4, 2025[7]. The annual gift exclusion for 2026 is $19,000 per recipient[7].

Those numbers are high enough that a lot of owners stop thinking about estate tax entirely. I understand why. But a business that owns a building in Newport Beach and a share of a shopping center in Irvine is worth what a buyer will pay for all of it, and that figure can surprise people who still think of their holdings at what they paid in the 1980s. A valuation is cheap compared with finding out at the wrong time.

Estate tax and the building are separate questions

Families sometimes mix up three different taxes in one conversation. The federal estate tax is a tax on what you leave. California property tax reassessment, discussed above, is a local tax that rises when ownership changes. Income tax on a later sale is a third question entirely, and it depends on the basis the heirs receive. Each one has different rules and a different professional who should be advising on it. I cover the inherited basis question for houses in Inheriting a House in California: Will You Owe Capital Gains Tax?

What a Buy-Sell Agreement Should Answer Before Anyone Needs It

The single document that replaces the handshake is the buy-sell agreement, whether it lives inside the company's governing agreement or stands alone. Your attorney drafts it. What you can do is arrive knowing which questions it has to answer, because the attorney can only write down decisions you have made.

• Trigger events. Death, of course, and also incapacity, divorce, retirement, a partner who simply wants out, and a partner who is no longer working in the business.
• Who buys. The remaining owners personally, or the company itself.
• The price. A fixed number nobody updates is the most common failure I see. A formula, or an appraisal process with a named method, ages better.
• The money. Where the buyer gets the funds. Insurance is the usual answer, and the coverage amount needs the same regular review as the price.
• The real estate. Whether buildings the company uses are inside the deal or held separately, and whether the business gets a written lease from the family that keeps the building.
• Payment terms. Cash at closing, or installments, and what security the selling family receives if they are paid over time.
• Deadlines. How many days each side has to act, so a death does not open an indefinite standoff.

Notice how many of those items involve real estate. That is not an accident. In a lot of Orange County family businesses, the building is worth more than the operating company, and an agreement that values the company without saying anything about the building has solved the smaller problem.

One more opinion. Review the agreement every three years at a minimum, and every time something big happens, such as a new building or a new partner. An agreement priced in 2012 is a gift to whichever side benefits from the stale number.

How to Hold the Real Estate Your Business Uses

There is no single right way to own business real estate, and anyone who gives you one answer without asking about your family has not done the work. Here is how the main options compare from the point of view of the person who will eventually have to sell.

The unfunded trust deserves its own warning. Families pay for a well drafted trust, sign it, put the binder on a shelf, and never record a deed moving the property into it. I explain what happens next in What Happens If a Home Was Never Transferred Into a Trust in California? The same thing happens with LLC interests that were supposed to be assigned to the trust and never were.

Pull a copy of the current recorded deed for every property you own. It takes minutes, and it is the only way to know how title actually reads today.

The Team That Protects a Business and Its Legacy

Protecting a family business takes more than one professional, and the failures I see usually come from people who never talked to each other. The estate planning attorney drafted the trust. A different attorney formed the LLC ten years earlier. The CPA prepares the returns and has never seen either document. The insurance agent sold a policy to fund a buyout at a price nobody remembers agreeing to.

Each of them did good work. Together they built something that contradicts itself.

Ask for one meeting, with everyone in the room or on the call, at least once. Bring the trust, the operating or partnership agreement, the buy-sell provisions, the insurance declarations, the current deeds and the most recent property tax bills. Ask each professional to say out loud what happens to the business and to each building if you die next month. If the answers do not match, you have found the work that needs doing.

Where do I fit? Usually later, when real estate has to be valued or sold as part of a trust administration or estate. I coordinate with the attorney and the CPA on pricing and on the documents the title company will require, and I can often tell a family early which problems are going to slow down a sale. That is the part of the process where my CPRES training and my legal background are most useful.

A Legacy Protection Review You Can Start This Month

If you own a business and real estate in Orange County, here is the order I would work through it. Each step produces something you can hand to your attorney.

1. Write down what you think the deal is. Every percentage and every promise about who buys whom and at what price. Have each partner do it separately, then compare. The differences are your agenda.
2. Gather the documents. Trust, will, partnership or operating agreement, any buy-sell terms, leases between you and your own company, insurance policies, and the recorded deed for every property.
3. Check title against the plan. If the trust says a building is in the trust and the deed says it is in your name, fix the deed before you fix anything else.
4. Get a current value. For the business and for each building. A broker opinion is a start for the real estate; your CPA will tell you when a formal appraisal is required.
5. Map the property tax exposure. Which properties would be reassessed at the next generation, and what the new tax bills would look like against today's cash flow[5][6].
6. Meet with a business attorney and an estate planning attorney together. Turn steps one through five into signed documents.
7. Put a review on the calendar. Every three years, and after any major change.

Seven steps, and none of them is complicated. The hard part is the first one, because it is the step where partners find out they never agreed on as much as they thought.

When the Day Comes: Selling or Holding the Property

Sometimes the plan was not finished in time. The partner died with the trust half funded and the operating agreement silent. Now a family has to decide what to do with a building.

The first decisions are about authority and order, not price. Who can sign? Does the business have a lease, and if not, what is the family going to do about the tenant who also happens to be the business? My trust sale checklist for California trustees walks through the steps before a listing, and if the heirs are divided about whether to sell at all, Siblings Can't Agree on Selling an Inherited House in California covers the options families have when there is no consensus.

The first days after a death matter more than people expect. Lock the building, find the keys and the alarm codes, confirm the insurance stays in force, and do not let anyone remove records or equipment until the person with authority has been identified. I wrote about those early hours in The $10,000 Suitcase: What to Do in the First 72 Hours After Inheriting a Property.

And sometimes the right answer is to hold. A building leased to a stable business at market rent can be a better inheritance than the cash from selling it. I will tell a family that when it is true. I will also tell them when the building is carrying a business that cannot pay a fair rent, because that is a conversation the handshake was always going to postpone until someone had to have it.
