Coverage in an underinsured-motorist case is often a scavenger hunt. The at-fault driver's limits are inadequate, so the recovery depends on how many UM/UIM policies the claimant can reach. One of the richest veins is the household policy: an injured person who counts as a resident relative under a family member's auto policy picks up an entire additional layer of coverage. A Pennsylvania decision from May reminds practitioners that the gateway word "resident" carries real weight, and that an adult who has physically moved out can lose access to it no matter how strong the family ties remain.
The ruling
In Lanunziata v. Pennsylvania National Mutual Casualty Insurance Company, reported at 2026 PA Super 97 and decided May 13, 2026, the Superior Court of Pennsylvania affirmed summary judgment for the carrier. The claimant, Kyle Lanunziata, was struck by a driver in 2020 and sought underinsured-motorist benefits under his parents' Penn National policy. The dispositive question was whether he was a resident of his parents' household at the time of the crash. The panel held he was not, so he was not an insured under the policy and no UIM coverage attached.
Why the family ties did not save the claim
The facts were not close, which is part of what makes the opinion useful. Lanunziata had moved out of his parents' home in 2017 or 2018 and signed his own apartment lease in 2019. He was living in that apartment when the collision happened. His argument for residency rested on continuing connections: he ate lunch at his parents' house nearly every weekday and on most weekends, kept his mail delivered there, and left some belongings on the property.
The court drew the line Pennsylvania law has long recognized between domicile and residence, and it held that residency for coverage purposes requires some measure of permanency or habitual physical presence, not merely a durable emotional or logistical link. An adult living independently under his own lease was not a resident of his parents' household simply because he visited often and used their address for mail. The connections he cited went to sentiment and convenience, not to where he actually lived.
Residency for coverage requires habitual physical presence with some measure of permanency. A standing lunch date and a mailing address do not supply it.
The theory on both sides
For the claimant, the theory was expansive: household membership should turn on the totality of a person's ongoing relationship with the home, so that frequent presence and retained belongings keep an adult child inside the coverage tent. For the carrier, the theory was that residency is a factual condition tied to where a person actually sleeps and keeps a life, and that a signed lease elsewhere is close to dispositive. The court sided with the carrier's narrower reading, consistent with the direction most jurisdictions have taken when a claimant tries to stretch resident-relative language past the point of actual cohabitation.
What it means for case-building
The practical lesson lands at intake, long before any coverage dispute. When you take an auto case with soft liability limits, map every policy in the client's orbit: the client's own coverage, resident relatives' coverage, and any policy on a vehicle in the household. Then test residency honestly against the standard the forum applies, because the carrier will.
- Pin down the living situation as of the crash date. Where did the client sleep, keep clothes, receive bills, register to vote, and address a license? A lease in the client's name at another address is a fact the defense will build its motion around.
- Distinguish domicile from residence. A young adult may still be domiciled at a family home for other legal purposes and yet fail the residency test for coverage. Do not assume the two travel together.
- Gather the residency proof early. If the client genuinely lives in the household, document it while the evidence is fresh: shared utilities, a room kept and used, receipt of mail that matters, and testimony from family members describing actual daily presence rather than visits.
- Value the case against the coverage that will actually attach. If household coverage is doubtful, price the file on the limits you can reliably reach and set client expectations accordingly.
The larger pattern
Lanunziata is a state-court reading of one policy's resident-relative clause, and residency standards are not uniform across jurisdictions. Some states weigh a broader set of factors and will find residency on facts a Pennsylvania panel rejected. But the underlying tension is the same everywhere: carriers write household and resident-relative language to capture people who share a home and to exclude those who have moved on, and courts increasingly enforce that line against adult children who have set up independent lives.
The takeaway for the plaintiff bar is not defeatism. It is diligence. Resident-relative coverage remains one of the most valuable tools in an underinsured case, and it is worth fighting for when the facts support it. The claims that fail are the ones where counsel assumed household membership instead of proving it.
