Common examples of a divorce attorney’s conflict of interest include trying to represent both spouses at once, having previously represented your spouse (or even just consulted with them), holding a personal or business relationship with your spouse, and owning a financial stake in property that will be divided in the case. Each of these situations is governed by the American Bar Association’s Model Rules of Professional Conduct, and each one can quietly weaken the advocacy you are paying for. Spotting the pattern early is how you protect your case.
One Attorney Representing Both Spouses
The most obvious conflict is a single lawyer offering to handle the divorce for both of you. ABA Model Rule 1.7 says a concurrent conflict exists whenever representing one client is “directly adverse” to another, or when there is a significant risk that the lawyer’s work for one client will be limited by obligations owed to the other.1American Bar Association. ABA Model Rules of Professional Conduct Rule 1.7 Conflict of Interest Current Clients A contested divorce puts spouses on opposite sides of every meaningful question: the house, retirement accounts, custody, support. No lawyer can push hard for one spouse on those questions without pushing against the other.
Even when the split looks amicable, this problem does not go away. ABA commentary on Rule 1.7 describes some conflicts as “nonconsentable,” meaning no client agreement can cure them, and representing two clients asserting claims against each other in the same proceeding is one of them.2American Bar Association. ABA Model Rules of Professional Conduct Rule 1.7 Conflict of Interest Current Clients – Comment If an attorney pitches dual representation as a way to save on fees, treat that as a warning.
A Lawyer Who Previously Represented Your Spouse
If the attorney you are considering ever represented your spouse before, ABA Model Rule 1.9 is likely triggered. The rule bars a lawyer from taking on a new client in the same or a “substantially related” matter when the new client’s interests are “materially adverse” to those of the former client.3American Bar Association. Rule 1.9 Duties to Former Clients The reason is simple. The lawyer picked up confidential information the first time around and could now use it against the person who trusted them with it.
This shows up in ordinary ways. A lawyer who drafted your spouse’s estate plan five years ago knows about assets, debts, and family friction. A lawyer who handled your spouse’s old business dispute has watched them negotiate under pressure. That inside knowledge is exactly what the ethics rules aim to keep off the table. A waiver from the former client, in writing, is the only way past Rule 1.9, and in a divorce that consent rarely comes.
A Consultation Your Spouse Had With the Lawyer
Your spouse does not need to have hired a lawyer for the conflict to attach. ABA Model Rule 1.18 protects “prospective clients,” meaning anyone who discusses the possibility of hiring the attorney, even without follow-through. If your spouse met with a lawyer and shared sensitive information about finances, the marriage, or custody, that lawyer typically cannot then represent you.4American Bar Association. Rule 1.18 Duties to Prospective Client[/mfm]
The disqualification applies when the lawyer received information that “could be significantly harmful” to the prospective client if used by the other side. In a divorce, almost everything shared at a consultation qualifies: income, hidden assets, custody weak points, appetite for settlement.
The “Conflicting Out” Tactic
Some spouses use this rule as a weapon. They book consultations with every strong divorce lawyer in the area, share just enough to trigger Rule 1.18 at each one, and then hire none of them. The point is to leave the other spouse without good options. Family law practitioners see this behavior often. Courts have pushed back in the most extreme cases, but the rule still applies whenever genuinely confidential information changes hands.
The Screening Exception
Rule 1.18(d) offers a narrow way out. If the consulted lawyer took only what was reasonably necessary to decide whether to accept the matter, the rest of the firm can still represent the other spouse, provided the consulted lawyer is immediately screened from the case, gets no share of the fee, and the prospective client receives prompt written notice.4American Bar Association. Rule 1.18 Duties to Prospective Client Screening works at larger firms where a genuine wall can be built. At a two-lawyer practice, it usually cannot.
Personal or Business Ties to Your Spouse
Your attorney’s own life can produce a conflict. Rule 1.7 also bars representation when a lawyer’s personal interests create a significant risk of limiting the quality of the work.1American Bar Association. ABA Model Rules of Professional Conduct Rule 1.7 Conflict of Interest Current Clients Picture a lawyer who is close friends with your spouse, moves in the same social circle, or is related to them. That pull can quietly soften advocacy. The lawyer may avoid aggressive but appropriate positions to protect a relationship that matters to them outside the case.
Business ties raise the same issue. If your lawyer co-owns a rental property with your spouse, shares investment accounts with them, or has an ongoing professional arrangement with them, the lawyer has a reason to protect that outside connection. Advice may drift toward a settlement that preserves the lawyer’s own interests rather than one that gets you the best result. No bad intent is needed. The risk of divided loyalty alone is enough.
A Financial Stake in Marital Property
ABA Model Rule 1.8 covers a sharper version of the money problem: the attorney’s personal financial interest directly clashing with the client’s. Under Rule 1.8(a), a lawyer cannot enter a business transaction with a client or acquire an interest adverse to a client unless the terms are fair, fully disclosed in writing, the client has a chance to get independent legal advice, and the client consents in a signed writing.5American Bar Association. Rule 1.8 Current Clients Specific Rules
In a divorce, this comes up when the lawyer owns part of an asset that is about to be divided. Say the attorney co-invested with one spouse in a commercial building, and that building is now marital property. The lawyer has a personal reason to influence its valuation, whether it gets sold, and on what terms. Any advice you get is shaped by what protects the investment.
Media or Book Rights to Your Story
Rule 1.8(d) prohibits a lawyer from negotiating for the rights to tell your story, whether through a book, documentary, podcast, or any other media, before your case is finished.5American Bar Association. Rule 1.8 Current Clients Specific Rules This matters mostly in high-profile divorces. A lawyer chasing a media deal has a reason to make litigation choices that produce a more dramatic story instead of choices that protect you.
When the Whole Firm Is Disqualified
A conflict does not stop with one lawyer. Under ABA Model Rule 1.10, when one attorney at a firm is disqualified under Rule 1.7 or 1.9, every attorney at that firm is generally disqualified too.6American Bar Association. Rule 1.10 Imputation of Conflicts of Interest General Rule This is called imputed disqualification. If you hire a family law firm and later find out that a different attorney there once represented your spouse, the whole firm may have to withdraw.
Two exceptions are worth knowing. First, if the disqualified lawyer’s conflict is purely personal, such as a friendship with the opposing spouse, and that personal interest does not create a real risk of limiting the other lawyers’ work, the rest of the firm can continue. Second, when the conflict comes from a lateral hire who joined the firm from another practice, the firm can avoid disqualification by immediately screening that lawyer from the matter, cutting them out of the fee, and giving the affected former client prompt written notice.6American Bar Association. Rule 1.10 Imputation of Conflicts of Interest General Rule
When you are choosing a firm, ask whether anyone in the office has ever represented your spouse or has a relationship that could cause problems. Not just your specific attorney.
When a Conflict Can Be Waived, and When It Cannot
Not every conflict ends the representation. Under Rule 1.7(b), a conflict can be waived if the lawyer reasonably believes they can still provide competent representation, the representation is not prohibited by law, and each affected client gives informed consent confirmed in writing.1American Bar Association. ABA Model Rules of Professional Conduct Rule 1.7 Conflict of Interest Current Clients Informed consent means an actual conversation about the risks, not a paragraph buried in a retainer.
Rule 1.7(b)(3) puts some conflicts beyond waiver. A lawyer cannot represent one client while asserting claims against another current client in the same proceeding. That is exactly what a contested divorce is, which is why joint representation of both spouses in litigation cannot be fixed by any waiver, no matter how cooperative both sides feel at the start. Being asked to sign a waiver for a conflict that falls into this category is itself an ethical problem.
What to Do If You Suspect a Conflict
Start with a direct conversation. Many conflicts are honest oversights, and a straightforward exchange clears them up. If a real conflict exists, the attorney is ethically required to withdraw. Many will. The ones who dig in when confronted with a genuine conflict are the ones to worry about.
Motion to Disqualify Counsel
If the lawyer refuses to step aside, the formal remedy is a motion to disqualify. It is a written request asking the judge to remove the conflicted attorney from the case. The motion has to lay out specific facts: prior representation, financial ties, personal relationships, not vague suspicion. Courts take these motions seriously but also watch for tactical abuse, since forcing new counsel mid-case creates delay and expense.
Bar Complaint
Separately, you can file a disciplinary complaint with the attorney’s state bar. Every state has a disciplinary authority that investigates alleged ethical violations. You submit a written complaint, and if it raises a substantial question of misconduct, the attorney has to respond. Investigations can take many months, and outcomes range from dismissal to suspension or disbarment. A bar complaint will not directly fix your divorce, but it creates accountability and a record.
Legal Malpractice Claim
If the conflict actually cost you money, whether through a worse settlement, a lost custody position, or a missed asset, you may have a malpractice claim. You have to show the attorney breached their duty, the breach caused your harm, and you suffered measurable financial damage. That means proving your divorce would have come out differently with unconflicted counsel. It is a high bar, but with clear conflicts and quantifiable losses these claims do succeed.
Conflicts Discovered After the Divorce Is Final
A conflict that only comes to light after the judgment is a harder problem. Courts are reluctant to reopen settled cases, and the conflict alone may not be enough to vacate a divorce. You would generally need to show that the divided loyalty actually shaped the outcome, producing a settlement or ruling materially worse than what unconflicted counsel would have secured. The clearer the link between the conflict and specific decisions in the case, the better the odds. Even where reopening the divorce is not realistic, a malpractice claim against the conflicted attorney may still be worth pursuing if the financial harm can be measured.
