In most states, a real estate lawyer can represent both the buyer and the seller in the same transaction, but only after both parties give written informed consent and only if the lawyer reasonably believes they can handle the job fairly for each side. The trade-off is significant: the lawyer stops advocating for either of you and becomes a neutral document preparer. Whether that works for your deal depends on how much negotiation is left and how much you’re willing to give up in exchange for a lower legal bill.
Why Sharing a Lawyer Is a Conflict in the First Place
Every lawyer owes their client undivided loyalty and confidentiality. Those duties collide the moment the same attorney tries to serve both sides of a purchase. You want the lowest price; the seller wants the highest. You want repairs done before closing; the seller wants to hand over the keys as-is. A lawyer genuinely pushing for one side’s interests is, by definition, working against the other’s.
The American Bar Association’s Model Rules of Professional Conduct call this a “concurrent conflict of interest.” It exists whenever representing one client is directly adverse to another, or when there’s a significant risk that the lawyer’s duties to one will limit what they can do for the other.1American Bar Association. Rule 1.7 Conflict of Interest – Current Clients A buyer-seller transaction hits both triggers.
What Your State Allows
Each state adopts its own version of the attorney ethics rules, typically modeled on the ABA framework. Most states treat dual representation in real estate as a waivable conflict, meaning it’s allowed with proper consent. A smaller number of state bar associations have concluded that the buyer-seller conflict is too fundamental to be waived at all. The rules aren’t uniform, so check your state’s professional conduct standards before agreeing to share counsel.
Even in states that permit the arrangement, the ethics rules add a threshold requirement before the consent process begins: the lawyer must reasonably believe they can competently and diligently represent both parties despite the conflict.2American Bar Association. Rule 1.7 Conflict of Interest – Current Clients – Comment If the price is still contested, if inspection issues are unresolved, or if there’s any real disagreement between the parties, a careful attorney should decline before anyone signs a waiver.
What Informed Consent Actually Requires
Informed consent isn’t just agreeing to the arrangement. Under the ABA’s definition, it means you’ve received adequate information about the material risks and the reasonably available alternatives before you sign off.3American Bar Association. Rule 1.0 Terminology The lawyer can’t hand you a form and rush past it. They have to walk you through what you’re giving up.
At a minimum, the disclosure should cover these points:
- The lawyer will not negotiate on your behalf, push for better terms, or advise you on strategy. Their role becomes neutral.
- Confidentiality between the two of you disappears. Anything you tell the lawyer becomes available to the other side. If you mention you’d pay more than your current offer, the lawyer can’t hide that from the seller.
- Any prior professional relationship the lawyer has with the other party must be disclosed, along with how it could affect neutrality.2American Bar Association. Rule 1.7 Conflict of Interest – Current Clients – Comment
- If a dispute develops mid-transaction, the lawyer must drop both of you, and each side will need new counsel.
The consent has to be confirmed in writing. That can mean a written agreement you sign or a writing the lawyer sends promptly after an oral conversation confirming what you agreed to.3American Bar Association. Rule 1.0 Terminology Most attorneys handling dual representation use a formal waiver letter that both parties sign before any work starts. Don’t treat that document as a formality. It’s the single most important protection you have if something goes wrong later.
What the Shared Lawyer Can and Can’t Do
Once both sides consent, the lawyer effectively stops being a lawyer in the traditional sense. They become a neutral document preparer, sometimes called a scrivener, carrying out the mutual instructions of both parties without favoring either. Think of it less like hiring a lawyer and more like hiring someone to run the paperwork.
The tasks they can perform are ministerial: drafting the purchase agreement based on terms you and the seller have already worked out, preparing the deed and closing documents, running a title search, and making sure everything is filed correctly. What they cannot do is the work that actually makes a lawyer valuable. They can’t negotiate the purchase price for you, tell you whether the inspection report justifies a lower offer, suggest contingencies to protect your position, or recommend you walk away from a bad deal. If you need that kind of guidance, you need your own attorney.
People underestimate this trade-off. The savings from sharing a lawyer look appealing on the invoice, but you’re paying for a fraction of the service. A dedicated attorney reviewing the deal solely for your benefit would flag risks the neutral lawyer simply cannot raise with you.
The Confidentiality You’re Giving Up
Losing confidentiality during the transaction is obvious once the lawyer explains it. What catches people off guard is what happens after closing if things go sour. If you and the seller end up in court over the deal, neither of you can claim attorney-client privilege to shield your communications with the shared lawyer from the other party. Everything you told that lawyer about the transaction is fair game. This is known as the joint-client exception to attorney-client privilege, and it applies in a later lawsuit between the parties even if one of you objects.
The practical effect is real. Suppose you discover after closing that the seller knew about a foundation problem and you want to sue. In a normal attorney-client relationship, your communications with your lawyer would be protected. With dual representation, the seller’s attorney can access what you told the shared lawyer during the transaction, and the reverse is also true. You’ve given the other side a window into your legal thinking from day one.
What Happens If the Deal Gets Contentious
Real estate transactions that start friendly can turn adversarial fast. A home inspection reveals mold, the seller refuses to remediate, and suddenly the aligned interests aren’t aligned anymore. When that happens, the shared lawyer faces a mandatory exit. The ABA rules require a lawyer to withdraw when continuing the representation would violate the conflict-of-interest rules.4American Bar Association. Rule 1.16 Declining or Terminating Representation
The lawyer can’t pick a side. They can’t decide the seller is being unreasonable and keep working for you, or the reverse. They step away from both parties entirely. You each need to find new lawyers to catch up on a transaction already in motion. That means delays, duplicated legal costs, and a potentially weaker negotiating position because the replacement attorney is working with incomplete context. The money you saved by sharing counsel often disappears here.
When It Actually Makes Sense
Not every real estate deal involves hard-fought negotiation. Dual representation is most defensible when the transaction is genuinely low-conflict and the major terms are already settled. A sale between family members at an agreed price, a transfer between business partners winding down a joint venture, or a straightforward residential closing where both sides just need paperwork handled can all fit this mold. The common thread: neither party expects or needs the lawyer to advocate for them.
Even then, ask yourself whether you’d be comfortable with the other side knowing everything you say to the lawyer. If the answer is no, dual representation is the wrong call regardless of how simple the deal looks on paper.
Alternatives That Usually Work Better
The most direct alternative is separate representation, where each party hires their own attorney. It costs more upfront but gives each side a real advocate who can negotiate, flag risks specific to that client, and keep confidences private. Real estate attorney fees for a residential closing typically range from a few hundred to a few thousand dollars depending on the market and the deal, so the incremental cost of a second lawyer is usually modest against the price of the property.
Another option is for one side to hire an attorney while the other proceeds without one, using a title company or closing agent to handle their paperwork. This is common in states where attorney involvement isn’t required at closing. In states where it is, both parties will need to be represented in some form.
If you’re the buyer in a simple transaction and the seller already has a lawyer, consider hiring your own attorney just for a contract review rather than full representation. A one-time review of the purchase agreement and closing documents costs far less than full transactional work and still puts a professional set of eyes on the deal before you sign. That limited engagement sidesteps the dual representation problem entirely while keeping your costs down.
