Can You Represent Both of Us? Why One Lawyer Usually Can't Handle Both Parents in a DCF Fair Hearing

It happens often enough that I can predict it. I do a consultation with a parent about a DCF fair hearing — DCF has supported a 51B allegation of abuse or neglect, and the parent wants to appeal. Then, sometimes within the hour, sometimes the next day, I get a second call. It's the other parent. Same house, same children, same supported finding, same fair hearing. They ask a version of the same question: "Can you represent both of us? It would save us money, and we're not fighting each other — we're both fighting DCF."

It is a completely reasonable question to ask. And the honest answer, almost every time, is no — not because I doubt either parent, and not because Massachusetts law assumes parents in this situation are adversaries. The answer comes from two rules that govern every lawyer in this state, and understanding them explains not just what I can't do, but why the rule exists in the first place.

The First Call Already Creates Obligations

Most people assume that until they sign an engagement letter and pay a retainer, nothing they've told a lawyer matters yet. That's wrong, and it's wrong by design.

Under Mass. R. Prof. C. 1.18(a), a "prospective client" is simply "a person who consults with a lawyer about the possibility of forming a client-lawyer relationship with respect to a matter." That's it. No signed agreement, no fee paid, no formal engagement required. A phone consultation about a DCF fair hearing is squarely a "consultation" under the rule.

Rule 1.18(b) then imposes a real duty: a lawyer who learns confidential information from a prospective client "shall not use or reveal that information," even if no attorney-client relationship ever forms. And "confidential information" is defined broadly under Mass. R. Prof. C. 1.6(a) as "information gained during or relating to the representation of a client, whatever its source" — which the Board of Bar Overseers has confirmed applies to consultations "regardless of how brief the initial consultation may be."

So when the first parent calls me, tells me what happened, what the 51B alleges, and what they think their defense is, that information is protected the moment they say it — whether or not I ever end up representing them.

Why That First Call Can Block the Second One

This is where it gets consequential. Rule 1.18(c) says that if I received confidential information from the first parent that "could be significantly harmful" to them, I generally cannot later represent someone whose interests are materially adverse to them in the same or a substantially related matter. The fair hearing appeal of the same 51B finding is about as "substantially related" as it gets — it's the same matter.

The rule's own bar counsel guidance on this point is worth reading carefully: the test is whether the information "could be" significantly harmful, not whether I'd actually use it. A prospective client doesn't have to prove I'm going to weaponize what they told me — only that I now possess something that could hurt their position if the wrong person heard it. That is exactly the situation created by taking a consultation from one parent and then a call from the other about the same allegation.

There are two ways around this under Rule 1.18(d) — both parents give informed consent in writing, or I limited what I learned during the first consultation and screen myself off from the second matter entirely. In practice, in a fair hearing consultation where I'm trying to actually understand the case, neither workaround is realistic. I need the details to advise the first parent competently, which means I've already learned more than a "conflict check" worth of information.

The Deeper Problem: I Usually Can't Answer on Day One

Here's the part that surprises people the most: even setting the confidentiality issue aside, I frequently cannot tell you on the first call whether representing both parents would even be possible in principle — because I haven't seen DCF's discovery yet.

A supported 51B finding against both parents doesn't mean DCF's theory treats them identically. Sometimes the investigation record, once I actually read it, shows a defense that only works for one parent — an argument that the neglect, if it happened at all, was attributable to conduct or circumstances specific to the other parent. I can't know that until I've read the 51A report, the 51B investigation, the DCF case notes, and whatever else comes through discovery. Until then, any answer I give about joint representation is a guess.

Rule 1.7: The Conflict That Doesn't Go Away With Consent

This is the second rule at play, and it governs actual joint representation even after the confidentiality issue is resolved. Mass. R. Prof. C. 1.7(a) provides that a lawyer cannot represent a client if doing so creates a "concurrent conflict of interest," which exists if:

(1) the representation of one client will be directly adverse to another client; or (2) there is a significant risk that the representation of one or more clients will be materially limited by the lawyer's responsibilities to another client...

Rule 1.7(b) allows representation despite a conflict like this, but only if all four of the following are true:

(1) the lawyer reasonably believes that the lawyer will be able to provide competent and diligent representation to each affected client; (2) the representation is not prohibited by law; (3) the representation does not involve the assertion of a claim by one client against another client represented by the lawyer in the same litigation or other proceeding before a tribunal; and (4) each affected client gives informed consent, confirmed in writing.

A fair hearing is an adjudicatory proceeding before a hearing officer, which is why condition (3) matters here even though the two parents aren't suing each other — DCF is the opposing party to both. But condition (3) isn't the only obstacle. If effective advocacy for one parent requires me to argue that the neglect was really the other parent's doing, I have already failed condition (1): I cannot "reasonably believe" I can provide competent and diligent representation to both, because doing right by one client means actively undermining the other. That kind of conflict is not something informed consent can fix. Consent under Rule 1.7(b)(4) only matters if conditions (1) through (3) are satisfied first — and here, they typically aren't. No waiver, no matter how well-explained or willingly signed, cures a conflict where helping one client necessarily means hurting the other.

"We're Not Fighting Each Other" Doesn't End the Analysis

Most couples who call me genuinely aren't adversarial. They're both scared, both want their kids back or their case closed, and both are telling the truth when they say they're not pointing fingers at each other. And often, once I get the discovery, that turns out to be correct — I find arguments that help both parents without hurting either one. DCF's investigation was sloppy, or the allegations don't hold up under either parent's version of events, or the standard DCF applied was wrong as a matter of law regardless of which parent is asked.

Even then, I still don't take on both parents as clients. The reason is less about ethics rules at that point and more about what actually makes sense: if the strongest arguments help both parents equally, then only one attorney is needed to make them — the second parent doesn't need separate, paid representation of their own arguments, because there's only one set of arguments. Formally representing both anyway adds a real risk without adding value: if new evidence surfaces during the hearing, if cross-examination produces an inconsistency, or if the hearing officer's questioning exposes a divergence between the parents' accounts that wasn't visible in the paperwork, I would likely have to withdraw from representing both of them — not just adjust course with one. That is the well-established consequence of a conflict emerging mid-representation in a joint matter: withdrawal from all parties, often at the worst possible moment, in the middle of contested testimony, with no time left before a hearing officer's deadline to find new counsel.

That risk is exactly what Rule 1.7 is designed to prevent parents from walking into unknowingly.

What I Recommend Instead

When both parents in a household are named in the same 51B finding, here's what I actually tell them:

Get separate consultations, ideally with separate attorneys. This isn't a sales pitch for referral fees — it protects both of you. Each of you gets a lawyer who owes you undivided loyalty and who can tell you, privately, if there is any daylight between your position and your co-parent's, without having to manage a conflict in real time.

Expect your attorneys to coordinate where it makes sense. Separate representation doesn't mean adversarial representation. If both parents' arguments genuinely align, separate attorneys can and do coordinate strategy, split preparation, and avoid duplicated work — while each parent retains their own advocate who can pivot instantly and fully if something changes.

Don't wait for a "yes" on joint representation before starting. The deadline to request the fair hearing, and the discovery schedule once it's requested, don't pause while you look for one lawyer willing to represent you both. If a joint arrangement isn't going to work, the sooner both parents know that, the sooner both can actually get moving on the case.

The Bottom Line

I understand why the question comes up — cost, convenience, and a genuine sense that "we're on the same side" all make joint representation sound sensible. But the Rules of Professional Conduct exist precisely because "we're on the same side" is a conclusion I can't verify until I've read what DCF actually has, and because even a small chance that helping one parent requires undermining the other means informed consent cannot make the conflict go away. When I decline joint representation, it isn't a judgment about either parent's honesty. It's the rule doing exactly what it's supposed to do — making sure that if one of you ever needs an argument the other's lawyer couldn't make, you already have a lawyer who can make it.
