In the real estate world, not every agreement shows up as a neatly typed document with signatures, dates, and all the boilerplate. Sometimes people rely on a verbal understanding, a simple handshake, or a casual note scribbled on a napkin. In Arizona, and in real estate law more broadly, that kind of arrangement is described as informal. Here’s the thing: while informal agreements can feel comfortable in the moment, they ride a very different legal dog sled from formal, written contracts.

What does informal mean in real estate contracts?

Imagine you’re chatting with a seller after a showing, and you and the seller agree on a price and timeline, but you never commit those terms to a written document. If someone asked you to describe that arrangement, you’d likely call it informal. It’s characteristically verbal and lacks a formal written record outlining the key terms—price, duration, contingencies, and who will do what.

Informal deals often rely on trust, memory, and the parties’ mutual expectations rather than documented specifics. They can feel flexible and quick—great for starting a conversation or testing the waters. But in the world of property—where big numbers, long timelines, and specific conditions hang in the balance—that flexibility can become a problem fast. In practical terms, an informal agreement may not be enforceable as a real estate contract because it isn’t written down with the essential terms, signatures, and dates that a court would expect.

A quick contrast to sharpen the idea

• Executed: This term is all about completion. An executed contract has been signed and carried out or fulfilled. It’s the mirror image of an informal agreement: a formal, written record with the obligations clearly in place and typically ready to enforce.

• Bilateral: This describes the structure of the agreement, not its format. A bilateral contract involves mutual promises between two parties. It says who is obligated to act and what they must do, but it doesn’t tell you whether the document is in writing or merely spoken.

• Informal: The winner in our line-up of terms for an agreement without a formal written record. It signals that the emphasis is on the spoken understanding rather than the documented specifics.

Why the distinction matters in Arizona

Arizona real estate contracts have a strong preference for written documentation. The state, like many others, follows the statute of frauds, which typically requires certain types of agreements—especially those involving land—to be in writing to be enforceable. That means an informal, verbal arrangement concerning real estate is risky because:

• It’s harder to prove what was actually agreed upon if a dispute arises.

• Essential terms (price, payment method, closing date, disclosures, contingencies) may be vague or missing.

• Enforceability becomes a moving target, and you end up navigating memories versus actual records.

This is not a moral story about being a buzzkill; it’s a practical note for anyone involved in Arizona property transactions. The comfort of a spoken agreement can quickly collide with the realities of closing a deal, obtaining clear title, handling earnest money, and meeting regulatory disclosures.

A real-world flavor: when a handshake meets the clock

Let me explain with a tiny scenario. You meet a potential buyer at a coffee shop. You talk through a price, a timeline, and a couple of contingencies. You leave with a mutual understanding, perhaps even a handshake and a promise to draft something later. Fast forward a week, and the seller has a change of heart, or the buyer discovers a snag, or a neighbor raises an concern about zoning. Without a written document, both sides are left to recall what was said, when it was said, and under what conditions the deal would move forward. Tension rises, trust gets tested, and the path to a clean, legal transfer of property gets muddier.

In real estate, that muddiness isn’t a mere inconvenience. It can slow down transactions, create miscommunications, and invite disputes that eat up time and money. It also highlights a key habit for anyone dealing with property: when in doubt, put it in writing. The moment you capture terms, responsibilities, and consequences in a document or contract, you move from informal to something more solid and enforceable.

What to watch for in contract terms

• Clarity of terms: An informal agreement often leaves critical details open or vague. In a written document, you’d expect to see price, closing date, who pays which fees, inspection rights, and disclosures spelled out clearly.

• Signatures and dates: A formal contract demonstrates consent with signatures, and it’s anchored by dates that mark the timeline—offer, acceptance, and execution dates.

• Contingencies and conditions: An informal deal may skip contingencies (financing, appraisal, title review). In writing, contingencies provide a safety net for buyers and sellers.

• Documentation trail: Written agreements create a paper trail that lenders, title companies, and agents can verify. This reduces confusion and helps coordinate the closing process.

A quick comparison to keep things straight

• Informal: Verbal or unwritten understanding. Flexible, but risky for real estate.

• Executed: A contract that’s both signed and carried out. It’s complete and typically enforceable as written.

• Bilateral: A relationship where both sides owe duties, regardless of format. The term points to mutual obligations, not to whether the document is written or oral.

Arizona-specific nuances worth noting

• Writing is typically expected for real estate deals in Arizona. While you might hear about informal conversations, the enforceable heart of a property transaction is a written agreement that captures key terms and responsibilities.

• Disclosures matter. Arizona franchises, broker requirements, and local ordinances shape what needs to be included in writing and what can be left to verbal understanding in particular contexts (for example, certain disclosures and timelines).

• Digital tools are common: In practice, you’ll see documents prepared in forms libraries operated by the Arizona Association of Realtors, ARMLS (Arizona Regional MLS), or brokerages that use DocuSign and other e-sign platforms to keep everything tidy, auditable, and legally sound.

Practical takeaways you can use

• If you’re ever tempted by a quick, informal understanding for real estate, remember: the more you can capture in writing, the clearer everyone’s expectations will be. A simple email outlining price, dates, and basic terms can be a smart first step, but it’s not a substitute for a formal document if you’re aiming for enforceability.

• Consider the role of “reliance” in disputes. If one party acts on a verbal deal (like taking other offers off the market or investing time and money based on an unwritten agreement), a court will weigh whether that party reasonably relied on the terms. Still, that reliance is unlikely to overcome the absence of a written agreement when essential terms are missing.

• Use professional guidance. Real estate pros—agents, brokers, and attorneys—often advocate for written contracts because they reduce ambiguity and support smooth closings. Tools from trusted sources can help you draft, review, and store these agreements so nothing slips through the cracks.

A few more practical touches

• Disclosures aren’t fashionable window dressing; they’re functional. When you're drafting or reviewing a contract, you want clear lines on property condition, known defects, and any legally mandated disclosures. That’s where formal writing earns its keep.

• Timing is everything. In Arizona deals, the timeline from offer to acceptance to closing is spelled out in writing so neither side loses sight of deadlines. An informal agreement leaves too much room for drift and misinterpretation.

• Keep it professional, even in casual settings. If a conversation about a property starts with a smile and a handshake, it’s fine—just don’t let the handshake be the ending. Move to written terms as soon as you can.

A friendly wrap-up

Informal agreements—that looser, verbal kind—have their place in the world of real estate, but they’re not the backbone of Arizona property transactions. The term “informal” describes agreements that lack a formal written record. In contrast, executed contracts are signed and completed, and bilateral contracts describe two-sided promises. For real estate, the punchline is simple: write it down. The right document protects your time, money, and peace of mind, and it helps everyone move from a hopeful conversation to a secure closing.

If you’re curious to dig deeper, keep exploring definitions and practical examples, especially how Arizona law treats writing requirements, disclosures, and closing procedures. Look for resources from the Arizona Association of Realtors, local brokerages, and reputable legal guides that focus on real estate contracts. And when you’re faced with a real-world scenario, remember the core lesson: informal can be convenient, but written clarity is king in real estate. It’s the difference between a good conversation and a solid contract that stands up when it matters most.
