In residential real estate, the attorney review period usually runs three to five business days after both the buyer and seller have received a fully signed contract. During that window, either side’s attorney can read the agreement, propose changes, or cancel the deal outright. If no one acts before the clock runs out, the contract becomes fully binding exactly as the agents drafted it.
When the Clock Starts
The period begins once both parties have received copies of the fully signed contract, not when the first signature goes down. If you sign on Monday and the seller signs on Wednesday, Wednesday is day zero. The day of signing itself often doesn’t count as the first day, and weekends and federal holidays are excluded in most jurisdictions that measure the window in business days.
Work through an example. In an area where the standard is three business days, a contract signed Tuesday afternoon would give the attorneys until the close of business Friday. A contract signed Thursday might not expire until the following Wednesday, because Saturday and Sunday don’t count. Track the deadline carefully. Missing it by even a few hours locks the contract in as written.
What Attorneys Do During the Window
Each side’s attorney reads through the contract looking for problems. Agents draft these contracts from standard templates, and those templates don’t always reflect the specific deal in front of you. An attorney might catch that the closing date conflicts with your mortgage rate lock, that there’s no home inspection contingency, or that a repair credit was worded in a way that doesn’t actually obligate the seller to do anything.
Most of the real work happens through modification letters. One attorney proposes specific changes; the other reviews them, accepts some, rejects others, and counters. Common additions include an inspection contingency, adjustments to the closing timeline, how the earnest money deposit is handled, which fixtures and appliances stay, and a requirement that the seller deliver clear title. That back-and-forth can finish inside the review window or, by mutual agreement, extend past it.
How Cancellation Works
Either party’s attorney can disapprove the contract during the review period, which effectively kills the deal. The attorney sends a written notice of disapproval to the other party’s attorney and to the real estate agents involved. In most jurisdictions where attorney review is customary, the disapproval doesn’t require a specific legal reason. The client may have changed their mind, found a better property, or decided the terms weren’t favorable enough.
Courts have generally upheld this broad cancellation power. In at least one reported case, a seller’s attorney terminated a contract during the review period specifically because the seller had received a higher competing offer, and the court found the termination valid. That flexibility is the whole point of the window: neither party is locked in until it closes.
The notice doesn’t need to follow a rigid format, but it does need to reach the right people before the deadline. Courts have accepted disapproval sent by email, fax, and overnight mail with delivery confirmation, not only by certified mail or personal delivery. What matters is actual, timely receipt by the other party and the agents.
When a contract is properly cancelled during attorney review, the buyer’s earnest money deposit is returned. Because the contract never became binding, neither side owes anything to the other.
What Happens When the Period Ends
Three outcomes are possible once the window closes:
- No action taken. If neither attorney sends a disapproval or modification letter in time, the contract becomes binding exactly as the agents drafted it. This is the outcome that catches people off guard. Hiring an attorney doesn’t help if they don’t act within the deadline.
- Modifications accepted. If both attorneys agree on a set of revisions, the modified contract becomes binding. The agreed changes are usually documented in a rider or amendment attached to the original agreement.
- Disapproval or failed negotiations. If one attorney disapproves outright, or if the two sides propose competing modifications and can’t reach agreement, the contract is void. Both parties walk away, and the earnest money goes back to the buyer.
There is a gray area. If an attorney sends a disapproval letter but also proposes modifications, the contract isn’t dead yet. It sits in limbo while the attorneys negotiate, and only truly dies if one side explicitly walks away or the parties can’t agree on revised terms. That negotiation phase can run beyond the original three-to-five-day window, because both sides have effectively agreed to keep talking.
What Stretches the Timeline
The review period itself is fixed by the contract clause, but negotiations triggered by a modification letter can run much longer. Several things tend to stretch the process:
- Complex transactions. Unusual title histories, multiple liens, commercial components, or estate sales often require attorneys to dig into records that aren’t immediately available.
- Slow responses. When one side takes days to respond to proposed modifications, the back-and-forth drags out. Returning your attorney’s calls quickly makes a real difference.
- Additional inspections. If the attorney’s modifications add a home inspection contingency that wasn’t in the original contract, the inspection has to be scheduled and completed before negotiations can wrap up.
- Holiday weekends. Because weekends and holidays are excluded in most jurisdictions, a contract signed before a long weekend has a longer review period in calendar days.
Both parties can also agree in writing to extend the review period if talks are productive but need more time. Neither side is required to grant an extension, so the request itself can become a leverage point.
Does Your Contract Even Include Attorney Review
Attorney review clauses are standard practice in only a handful of states. In most of the country, residential contracts become binding once both parties sign, and buyers rely on inspection contingencies or financing contingencies to exit the deal. Even in states where attorney review is customary, the clause has to actually appear in the contract. It isn’t an automatic legal right that exists outside the four corners of the document. Before you sign anything, confirm the clause is there and understand exactly how many days it gives you.
The attorney review period is also not the same as an inspection contingency or a due diligence period. Attorney review is about the contract itself, whether the legal terms protect you and whether anything is missing. An inspection contingency is about the physical condition of the property. A due diligence period, used in some states that don’t have attorney review, gives the buyer a set number of days to investigate the property and walk away for any reason; it’s typically longer and buyer-initiated rather than available to both sides.
What It Costs
Most real estate attorneys charge a flat fee for contract review and closing work rather than billing by the hour. For a straightforward residential purchase, expect somewhere between $500 and $1,500, depending on your local market and the complexity of the deal. Attorneys in higher-cost markets charge more, and transactions involving co-ops, new construction, or unusual title issues push fees toward the higher end.
That fee usually covers more than the review period alone. It typically includes drafting modification letters, negotiating with the other side’s attorney, reviewing the title search, and attending closing. Set against a purchase that likely runs into the hundreds of thousands of dollars, the cost of having someone catch a problem in the contract is small relative to the risk of missing one.
