UBE Domicile

Last updated: May 2, 2026

Domicile questions are one of the highest-leverage areas to study for the UBE. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.

The rule

Domicile is the one place a person treats as their true, fixed, permanent home and to which they intend to return whenever absent. Every person has exactly one domicile at a time, and a domicile once established persists until a new one is acquired. To change domicile, a competent adult must (1) be physically present in the new place and (2) form the concurrent intent to remain there indefinitely (the traditional 'animus manendi'). The Restatement (Second) of Conflict of Laws §§ 11-23 govern; for federal diversity jurisdiction under 28 U.S.C. § 1332, citizenship of a natural person equals domicile.

Elements breakdown

Domicile of Origin

The domicile assigned to a person at birth, which controls until lawfully changed.

  • Assigned by operation of law at birth
  • For marital child: domicile of father (modern: either parent)
  • For nonmarital child: domicile of mother
  • Persists until domicile of choice acquired

Common examples:

  • Child born in Ohio to parents domiciled in Ohio takes Ohio as domicile of origin
  • Child born during temporary travel takes parents' domicile, not place of birth

Domicile of Choice

A new domicile acquired by a competent adult through the concurrent union of presence and intent.

  • Person has legal capacity to choose
  • Physical presence in the new place
  • Concurrent intent to remain indefinitely
  • Abandonment of prior domicile (occurs by operation of acquiring new one)

Common examples:

  • Adult moves to Texas, rents an apartment, and intends to stay indefinitely
  • Intent need not be permanent forever — indefinite is enough

Domicile by Operation of Law

A domicile assigned to persons lacking legal capacity to choose their own.

  • Person lacks capacity (minor, adjudicated incompetent)
  • Domicile attaches to that of the legal custodian or guardian
  • Changes automatically when custodian's domicile changes
  • Married adults each may have independent domicile (modern rule)

Common examples:

  • Minor's domicile follows custodial parent
  • Incompetent adult's domicile follows court-appointed guardian

Retention of Existing Domicile

A domicile, once established, continues until both elements of a change are satisfied.

  • Prior domicile presumed to continue
  • Burden on party asserting change
  • Mere absence does not change domicile
  • Floating intent ('someday I'll move') insufficient

Common examples:

  • Student attending college in another state ordinarily retains parental domicile
  • Soldier stationed abroad retains pre-service domicile absent affirmative change

Federal Diversity Citizenship

For 28 U.S.C. § 1332, a natural person is a citizen of the state of their domicile, determined at the time the complaint is filed.

  • Citizenship measured at filing of complaint
  • Citizenship = domicile (not residence, not where you work)
  • U.S. citizen domiciled abroad is citizen of no state
  • Corporation: state of incorporation AND principal place of business

Common examples:

  • Plaintiff who moves to Florida one week before filing, intending to stay, is a Florida citizen
  • Mere ownership of a vacation home does not create citizenship there

Common patterns and traps

The Floating-Intent Trap

Test-writers love facts where a person clearly intends to move 'someday' or 'when the kids graduate' but has not yet relocated. Bar candidates often credit this future intent as enough to shift domicile, but without present physical presence in the new place, no change has occurred. The prior domicile continues to control with full force.

An answer choice that says the party is now domiciled in the new state 'because she intends to move there after retirement.'

The Residence-Equals-Domicile Confusion

Many fact patterns describe a person 'living' or 'residing' in a state — at school, on temporary assignment, in military service, or in a vacation home. Distractors equate this physical presence with domicile, ignoring that domicile requires the additional element of intent to remain indefinitely. A person can have multiple residences but only one domicile.

An answer choice asserting diversity is destroyed because both parties 'reside' in the same state.

The Diversity Snapshot Rule

For 28 U.S.C. § 1332, citizenship is fixed at the moment the complaint is filed. Post-filing moves do not create or destroy diversity, and pre-filing moves do count if accompanied by intent. Distractors test whether you anchor the analysis to the filing date or wrongly use a later or earlier event.

An answer choice that says diversity is destroyed because the plaintiff moved to defendant's state two months after filing.

The Capacity Override

Minors, incompetents, and (in older formulations) married women cannot acquire a domicile of choice; their domicile follows by operation of law. Modern majority rule treats spouses as fully independent for domicile, but the minor/guardian rule remains. Distractors apply the choice analysis to a person without capacity, or apply the outdated 'wife follows husband' rule.

An answer choice that analyzes a 14-year-old's expressed intent to remain in a new state as if she could form animus manendi.

The Sticky-Domicile Default

When facts are ambiguous about whether the new place is 'home,' the prior domicile wins. The party asserting change bears the burden, and equivocal indicia (kept old driver's license, retained voter registration, ongoing return visits) tilt against finding a change. This is essentially a tiebreaker rule that rewards careful candidates.

An answer choice that finds a change of domicile based on a single move with mixed indicia, where the better answer retains the original domicile.

How it works

Think of domicile as a sticky default. Imagine Reyes was born and raised in Illinois, then took a two-year project assignment in Arizona while keeping his Chicago condo, his Illinois driver's license, and telling friends he plans to return when the project ends. Reyes is still domiciled in Illinois — he has presence in Arizona but lacks the intent to remain indefinitely, so the Illinois domicile of origin persists. If midway through the assignment he sells the Chicago condo, registers to vote in Arizona, and tells everyone Arizona is now home, the two elements (presence + intent to remain indefinitely) coincide and his domicile shifts to Arizona at that moment. The shift is instantaneous when both elements unite; the candidate's job is to pinpoint the moment intent and presence coexist, then identify the legal consequences flowing from the domicile at the relevant time (filing of suit, death, marriage, taxation).

Worked examples

Worked Example 1

Is there subject-matter jurisdiction based on diversity of citizenship?

  • A Yes, because Patel was a Georgia citizen at the time the complaint was filed and the amount in controversy exceeds $75,000. ✓ Correct
  • B Yes, because Patel maintained property and a driver's license in Georgia, conclusively establishing Georgia citizenship.
  • C No, because Patel was physically present in Nevada when the suit was filed, making her a Nevada citizen for diversity purposes.
  • D No, because a temporary 14-month residence in Nevada destroys complete diversity regardless of intent.

Why A is correct: Diversity citizenship for a natural person equals domicile measured at the moment the complaint is filed. Patel's presence in Nevada is undisputed, but she lacks the intent to remain indefinitely — she expressly plans to return to Georgia when the project ends. Her Georgia domicile of origin therefore persists, and complete diversity exists between a Georgia plaintiff and a Nevada defendant. The amount in controversy exceeds the $75,000 threshold under 28 U.S.C. § 1332(a).

Why each wrong choice fails:

  • B: Right outcome but wrong reasoning. The driver's license and condo are evidentiary indicia of intent, not 'conclusive' proof — domicile turns on the totality of intent and presence, not on any single document. (The Residence-Equals-Domicile Confusion)
  • C: This wrongly equates residence with domicile. Mere physical presence in Nevada does not make Patel a Nevada citizen; she must also intend to remain indefinitely, which she does not. (The Residence-Equals-Domicile Confusion)
  • D: There is no rule that a fixed-term residence automatically destroys or creates diversity. The analysis turns on the two-element domicile test, not the duration of the lease. (The Sticky-Domicile Default)
Worked Example 2

Which state's intestacy law governs the distribution of Reyes's personal property?

  • A Michigan's, because Reyes had not lived in Oregon long enough to abandon his 20-year Michigan domicile.
  • B Oregon's, because Reyes was physically present in Oregon with the concurrent intent to remain indefinitely at the time of his death. ✓ Correct
  • C Michigan's, because a domicile of origin can only be replaced after a substantial period of physical presence in the new state.
  • D Oregon's, because the location of death always controls the distribution of personal property.

Why B is correct: Distribution of personal property is governed by the law of the decedent's domicile at death (Restatement (Second) of Conflict of Laws § 260). Reyes satisfied both elements of a domicile of choice on March 1: physical presence in Oregon coupled with intent to remain indefinitely, demonstrated by the lease, voter registration, license surrender, and his stated commitment. The change is instantaneous when presence and intent unite; no minimum duration is required. Oregon law therefore controls.

Why each wrong choice fails:

  • A: There is no minimum-duration requirement for a change of domicile. Once presence and intent coincide, the change is effective immediately, even if only minutes have passed. (The Sticky-Domicile Default)
  • C: This invents a rule. A domicile of choice replaces a domicile of origin the moment both elements unite — the original Michigan domicile carried no special longevity protection. (The Sticky-Domicile Default)
  • D: Place of death is irrelevant to choice of law for personal property; what matters is domicile at death. A person who dies on vacation does not have vacation-state law applied to their estate. (The Residence-Equals-Domicile Confusion)
Worked Example 3

Of which state is Liu a citizen for diversity purposes?

  • A Vermont, because Liu has expressed a fixed intent to return to Vermont and to remain there as soon as she reaches majority.
  • B Vermont, because a domicile of origin can never be displaced by a custodian's unilateral move.
  • C North Carolina, because Liu's domicile follows that of her custodial parent, who has acquired a North Carolina domicile. ✓ Correct
  • D Neither state, because Liu's expressed intent conflicts with her physical presence and no domicile can be determined.

Why C is correct: A minor lacks legal capacity to acquire a domicile of choice; her domicile is assigned by operation of law and follows her custodial parent. Liu's mother satisfied both elements of a North Carolina domicile of choice — physical presence plus intent to remain indefinitely (selling the Vermont home, buying in Raleigh, taking permanent employment). Liu's domicile therefore changed automatically with her mother's, regardless of Liu's own preferences. Liu is a North Carolina citizen for diversity purposes.

Why each wrong choice fails:

  • A: This applies the choice analysis to a person who lacks capacity to make the choice. A 15-year-old cannot form the legally operative animus manendi; her stated intent is irrelevant to the domicile determination. (The Capacity Override)
  • B: This overstates the stickiness of the domicile of origin. A minor's domicile changes whenever her custodian's domicile changes — that is precisely how the operation-of-law rule works. (The Sticky-Domicile Default)
  • D: Every person always has exactly one domicile; the rules are designed to ensure no one is left without one. The minor-follows-custodian rule resolves the question without resort to the minor's own intent. (The Capacity Override)

Memory aid

PIE: Presence + Intent = Establishment. To change domicile you need both, simultaneously, and you can only have one at a time.

Key distinction

Presence alone (residence) is not domicile, and intent alone (a wish to move) is not domicile — both must coincide in the same place at the same time, and the prior domicile clings until that union occurs.

Summary

Domicile requires concurrent physical presence and intent to remain indefinitely; absent both, the prior domicile controls.
