The opinion of the Court was delivered by
This appeal requires us to interpret a clause in a homeowners’ liability insurance policy that provides a defense and indemnification to relatives of the named insured who are residents of the named insured’s household. The dispute arises from the fact that the named insured and the relative seeking coverage do not reside together, nor did they ever reside together. The insured, an elderly woman, moved out of the house she owned after suffering an injury, but continued to maintain her homeowners’ insurance policy and intended to return to her house when she was physically able to do so. Three years later, the insured’s grandson and his *666 wife moved into the vacant house. The issue is whether the insured’s grandson and his wife are residents of the insured’s household, thereby qualifying them as “insured persons” under the policy.

In 1931, Mary Maccia purchased a one-family house located at 14 Hyde Road, Bloomfield, New Jersey. Maccia resided there until 1990 when she sustained an injury in a fall that required her to move to her daughter’s home in Kearny so that her daughter could care for her. Because Maccia intended to return to 14 Hyde Road when her health improved, she did not sell her house. When she moved in with her daughter, Maccia left many of her belongings, including her furniture, kitchenware, china, silverware set, garden and household tools, wedding dress, and “personal knickknacks” in the house at 14 Hyde Road. She continued to have her mail, checking account statements, pension checks, social security checks, health plan notices, property tax assessments, and Medicare benefits statements sent to 14 Hyde Road. Maccia took only her clothing and other essential items with her to her daughter’s home in Kearny.
In 1993, because she was concerned about the risk of burglary and vandalism to her vacant house, Maccia asked her grandson, Donald Callaghan, and his wife, Marcella, to move into and care for her house. Donald Callaghan offered to purchase the property from his grandmother but she declined because she intended to return to her house when her health improved. The Callaghans agreed to pay Maccia $600 per month and to maintain the property. They also paid the electric, gas, heating, phone, and water bills. The Callaghans received their mail at 14 Hyde Road and were registered to vote at that address.
Maccia continued to pay the property taxes for her house. She also maintained her homeowners’ liability insurance policy issued by Allstate Insurance Company. Although the Callaghans had maintained a homeowners’ insurance policy in their names at their *667 previous residence, they did not purchase a policy when they moved to 14 Hyde Road.
The parties stipulated that Maccia intended to return to her house when her health permitted. However, from the time she moved in with her daughter until the filing of this appeal, she was unable to return to her house and was confined to her daughter’s home in Kearny. 1 Nevertheless, the Callaghans still considered one of the bedrooms in the house to be Maccia’s. The Callaghans visited Maccia at her daughter’s home approximately once each month.
The underlying action giving rise to this appeal is a tort claim filed against Marcella Callaghan. In September 1994, plaintiff, eighty-eight-year-old Dorothy Gibson, was seriously injured when she was knocked down by Marcella Callaghan’s dog while walking in Brookdale Park in Montclair. After Gibson and her husband filed a complaint against Marcella Callaghan, Marcella Callaghan filed a third-party complaint against Allstate, asserting that, because she resided in Maccia’s house, she was entitled to a defense and indemnification under Maccia’s homeowners’ policy. Marcella Callaghan also filed a third-party complaint against the County of Essex. That complaint has been dismissed and is not implicated in this appeal.
The Allstate policy lists Maccia as the named insured and identifies 14 Hyde Road as the insured property; The policy provides:
Losses We Cover:
Allstate will pay all sums arising from an accidental loss which an insured person becomes legally obligated to pay as damages because of bodily injury or property damage covered by this part of the policy.
We may investigate or settle any claim or suit for covered damages against an insured person. If an insured person is sued for these damages, we will provide a defense with counsel of our choice, even if the allegations are groundless, false or *668 fraudulent. We are not obligated to pay any claim or judgment after we have exhausted our limit of liability.
The “Definitions” section of the policy provides:
1. “You” and “your” — means the person named on the declarations page as the insured and that person’s resident spouse.
2. “Allstate”, “We”, “Us” or “Our” — means the company named on the declarations page.
3. “Insured person” — means you and, if a resident of your household:
a) any relative; and
b) any dependent person in your care.
[Emphasis supplied.]
Under the Family Liability Protection section of the policy, “insured person” also means “any person or organization legally responsible for loss caused by animals or watercraft covered by this policy which are owned by an insured person____” Significant for purposes of this appeal, the policy does not define the term “household.”
Allstate filed an answer to Marcella Callaghan’s third-party complaint, denying her the right to a defense and' indemnification because she did not, according to Allstate, qualify as an “insured person” under Maceia’s policy. Allstate moved for summary judgment and, in January 1996, the Law Division granted Allstate’s motion. Plaintiffs filed a successful motion for reconsideration, and subsequently the court granted Allstate’s motion to sever the coverage issue from the tort action. After a bench trial, the court issued a written opinion concluding that Marcella Callaghan did not qualify as an insured under Maccia’s Allstate policy, noting that “[s]uch matters as residence in the same abode, financial support or dependence, sharing of meals, socialization and teaching supervision ... are elements which determine whether a person is a member of a household.”
Following unsuccessful motions for reconsideration and leave to file an interlocutory appeal, Marcella Callaghan withdrew her defense to the tort action and a default was entered against her. After a proof hearing, judgment was entered in favor of plaintiff *669 Dorothy Gibson in the amount of $190,000 plus interest, and in the amount of $40,000 plus interest in favor of Gibson’s husband.
In an unpublished per curiam opinion, the Appellate Division affirmed the trial court’s denial of coverage. The Appellate Division relied on the definition of “household” contained in Black’s Law Dictionary:
Household, n. A family living together. Schurler v. Industrial Commission, 86 Utah 284,43 P.2d 696 , 699. Those who dwell under the same roof and compose a family.
Term “household” is generally synonymous with “family” for insurance purposes, and includes those who dwell together as a family under the same roof. Van Overbeke v. State Farm Mut. Auto. Ins. Co., 303 Minn. 387,227 N.W.2d 807 , 810. Generally, the term “household” as used in automobile policies is synonymous with “home” and “family.” Bartholet v. Berkness, 291 Minn. 123,189 N.W.2d 410 , 412.
[Black’s Law Dictionary 740 (6th ed.1990).]
Because Marcella Callaghan and Maccia had never lived together, the court held that they were not members of the same household.
We granted the petition for certification of plaintiffs Dorothy and John Gibson and the petition for certification of defendant/third-party plaintiff Marcella Callaghan. 156

With those principles in mind, we turn to the governing language in Maceia’s homeowners’ policy, “resident of your household.” As this Court stated almost forty years ago in

[h]ousehold is not a word of art. Its meaning is not confined within certain commonly known and universally accepted limits. True, it is frequently used to designate persons related by marriage or blood, who dwell together as a family under a single roof. But it has been said also that members of a family need not in all cases reside under a common roof in order to be deemed a part of the household.

Accordingly, whether a relative of a named insured is a resident of that insured’s household “will depend on the facts of each case.”

Intent is similarly relevant where a relative seeks coverage after having moved away from an insured’s household.

Allstate relies in part on cases from other jurisdictions that have held that a relative may not be entitled to coverage as a member of a named insured’s “household” even where that relative resides with the insured.

We hold that, at the time plaintiff Dorothy Gibson was injured by Marcella Callaghan’s dog, Marcella Callaghan was a resident of Maccia’s household. We decline Allstate’s invitation to adopt the restrictive definition of “household” contained in
Black’s Law Dictionary.
Residence under a common roof is not the touchstone of a “household”; rather, the meaning of “household” will vary depending on the circumstances of a given case. See
Mazzilli, supra,
35
N.J.
at 8,
We find that, under the unique set of circumstances presented in this appeal, the meaning of “insured person” in Maccia’s homeowners’ policy is ambiguous. Specifically, “resident of your household” is readily susceptible of two interpretations: a resident of 14 Hyde Road (the insured premises), or a person residing in the same house as Maceia. Because the language of the policy is ambiguous, we are required to construe the disputed terms in favor of the insured.
Cruz-Mendez, supra,
156
N.J.
at 571,
The insurance industry has known for almost forty years that the term “household” is susceptible of several interpretations. See

Further, a contrary holding would defeat the reasonable expectations of Maccia, the insured. See
DiOrio, supra,

N.J.
at 269,
We consider also the argument advanced by plaintiff Dorothy Gibson that because the Callaghans and Maccia shared the same domicile they were necessarily'residents of'the same household. That Maccia intended to return to her house when her health *679 improved, combined with all the other indicia of domicile, indicates that 14 Hyde Road remained her domicile. That conclusion supports our holding that 14 Hyde Road also constituted Maccia’s household for purposes of coverage under the Allstate policy.
We find it somewhat ironic that Allstate suggests that Donald and Marcella Callaghan, who were living in Maceia’s home in-order to protect it from vandalism, a risk covered by Allstate under the policy, are not residents of Maccia’s household. Moreover, plaintiffs’ counsel informed this Court at oral argument that the policy has been in effect and Maccia has been paying the premiums on the policy since 1962. Allstate’s receipt and acceptance of Maccia’s premiums for so long a period persuasively reflects Allstate’s understanding that the policy’s definition of “insured person” as including Maccia and any relative “resident of [her] household” constituted a concession and acknowledgment that, for purposes of the policy, Maccia resided in her own household at 14 Hyde Road. If Allstate intended to contest Maccia’s residence in her own “household,” as that term was used in the policy, then it was obligated to use a definition of “insured person” that acknowledged the possibility that Maccia might no longer reside at the insured premises.
We are not persuaded by the cases from other jurisdictions cited by Allstate. The eases that deny coverage to a relative residing in a house owned by a named insured who lives elsewhere,
e.g., Cain, supra,
*680 Nor do the cases that equate “household” with a “substantially integrated family relationship” between the insured and the relative seeking coverage dictate a different outcome. The inquiry in those cases was whether the relative seeking coverage, who did not reside exclusively in the insured premises, had a sufficient connection to the insured premises to be considered a member of that “household.” In this appeal, that the Callaghans are residents of 14 Hyde Road is beyond dispute: they live in the house, receive their mail there, and are registered to vote there. Rather, the question is whether, at the time plaintiff Dorothy Gibson was injured, 14 Hyde Road was Maccia’s household within the meaning of that term as used in Allstate’s policy. We conclude that it was.

The judgment of the Appellate Division is. reversed. We remand the matter to the Law Division for further proceedings consistent with this opinion.
