What Is Escrow? How Escrow Accounts Work

Escrow is an arrangement where a neutral third party holds money, securities, or other assets on behalf of two parties in a transaction, releasing them only once agreed-upon conditions are satisfied. It exists to solve a basic trust problem: in any deal where payment and delivery don’t happen at the exact same instant, one side is always exposed to the risk that the other backs out, fails to perform, or simply doesn’t pay. Escrow removes that risk by putting a disinterested party in the middle.

The basic mechanism

An escrow arrangement always has three participants: the two transacting parties and an escrow agent — typically a bank, title company, attorney, or specialized escrow service — who holds the funds or assets in a segregated account and has no stake in the outcome beyond following the agreed instructions.

The general flow looks the same regardless of what’s being held:

1. The parties agree on the conditions that must be met for the escrow to release — a closing date, a certificate of completion, a regulatory approval, a due-diligence period ending without objection.
2. One party deposits money or assets with the escrow agent.
3. The agent verifies the conditions are satisfied (or waits for both parties to jointly instruct release).
4. The agent disburses the funds or assets accordingly — either forward to completion, or back to the depositing party if the deal falls through.

Because the escrow agent has a fiduciary duty to follow the escrow instructions exactly, neither party can unilaterally access the funds early or redirect them, which is the entire point of using one.

Escrow in real estate

The most familiar use case is home buying. A buyer typically deposits an earnest money payment into escrow shortly after an offer is accepted, signaling serious intent to purchase. Over the following weeks, the escrow account also becomes the clearinghouse for the rest of the transaction: the buyer’s full down payment and loan proceeds, the seller’s payoff of any existing mortgage, and prorated amounts like property taxes and homeowners association dues all flow through it. On closing day, the escrow agent — often a title company — disburses everything simultaneously: sale proceeds to the seller, existing liens paid off, and the deed recorded in the buyer’s name. If the deal collapses before closing (say, an inspection reveals a serious defect and the buyer walks under a contingency clause), the earnest money is returned according to whatever the purchase contract specifies.

Mortgage servicers also run an ongoing form of escrow: a portion of a homeowner’s monthly payment is held in an escrow account and used to pay property taxes and insurance premiums when they come due, so the homeowner doesn’t have to save for those bills separately.

Escrow in M&A and startup deals

Escrow shows up constantly in company acquisitions, and for tech-industry readers this is often the more relevant context. When one company buys another, the buyer typically doesn’t hand over the full purchase price at closing. A portion — commonly 10-15% of the deal value — is held back in an indemnification escrow for a defined period, usually 12-24 months, to cover claims that surface after closing: undisclosed liabilities, breaches of the seller’s representations and warranties, or disputes over the final purchase price adjustment. If no claims arise, the escrowed funds release to the sellers at the end of the period. This is closely related to, but distinct from, an earnout, where additional payment is contingent on the acquired business hitting performance targets rather than on the absence of post-closing claims.

Escrow also appears earlier in a startup’s life. Some SAFE agreements and convertible note deals route initial funds through escrow until a minimum round size is reached, so early investors aren’t left exposed if the round fails to close. And in secondary sales of private company shares, escrow lets a buyer and seller complete a transfer without either side fronting trust to the other — useful in exactly the kind of illiquid, hard-to-verify transaction that private equity often is. For the broader mechanics of how those rounds come together, see how startup funding rounds work.

Escrow vs holdback vs trust accounts

These terms get used loosely, but they’re not identical:

	Escrow	Holdback	Trust account
Controlled by	Independent third-party agent	Buyer directly (no independent agent)	Trustee with fiduciary duty
Typical duration	Until specific conditions are met	Fixed contractual period	Can be indefinite
Common use	Real estate closing, M&A indemnification	Post-closing M&A holdback without separate agent	Client funds, estate assets

A holdback is functionally similar to an escrow but the withheld amount often stays with the buyer directly rather than moving to an independent agent, which gives the seller less protection against the buyer’s own insolvency or bad faith.

What escrow doesn’t protect against

Escrow protects against non-performance and outright fraud around the release of funds, but it doesn’t validate the underlying deal terms or guarantee the asset being transferred is what it’s represented to be. A title company holding funds in escrow for a home sale won’t catch a fraudulent property listing; an M&A escrow agent won’t independently verify that a seller’s financial disclosures are accurate. Escrow is a mechanism for enforcing an agreement both sides have already made, not a substitute for due diligence before making it.

The takeaway

Escrow puts a neutral third party in control of money or assets until agreed conditions are met, removing the risk that one side in a transaction pays or delivers before the other performs. It’s most visible in home buying, where it manages earnest money and the closing itself, but it’s just as central to company acquisitions, where indemnification escrows protect buyers against claims that surface after the deal closes. The mechanism is the same in both cases — a disinterested party following exact instructions — even though the stakes and dollar amounts look very different.
