A choice-of-law principle that selects the law of the jurisdiction having the closest connection to the parties and the particular issue. The principle evaluates contacts such as the location of a thing, the parties' domiciles, and the place of relevant conduct or transactions according to their relative importance. It produces the same result a court of the selected jurisdiction would reach on the actual facts.
BlueWave Shipping, based in State A, purchased a waterfront warehouse and pier located in State B from a seller domiciled in State C. After closing, the Delta Port Authority from State D asserted superior rights in the submerged lands. The court identified State B as having the most closely connected relationship to the land and the competing claims because the immovable property and its recording system were situated there.
River Ocean, headquartered in State A, acquired coastal property in State B under a contract designating State A law. Jeremy later asserted a prescriptive easement based on decades of use entirely within State B. The court applied the law that State B courts would apply because the immovable and the physical use giving rise to the claimed interest were located there.

A Mexican citizen sued U.S. officials for injuries suffered during an abduction carried out in Mexico. The court concluded that Mexico had the most closely connected relationship to the tort claim because the harm occurred there and Mexican law governed the underlying conduct.
An Oklahoma wife sued her husband for injuries sustained in a Missouri car accident. The court applied Missouri law because Missouri had the most closely connected relationship to the tort and the parties' conduct at the time of the injury.
The test weighs all contacts, including the location of the land, the parties' domiciles, and the place of the transaction, according to their relative importance for the specific issue. For immovables the situs usually predominates, yet the analysis still requires evaluating the § 6 factors rather than applying an automatic rule.

The contacts are aggregated and treated as if located in a single state for choice-of-law purposes. This aggregation simplifies the analysis without changing the outcome that would result under either state's identical rule.

For immovables the reference is to the whole law of the situs, including its choice-of-law rules, so the forum must reach the same result a situs court would reach. For movables the reference is ordinarily to local law only.

Protection of justified expectations receives substantial weight in property transactions because parties ordinarily consult counsel and rely on predictable legal consequences. When those expectations point to a state other than the situs, the court still balances them against the situs's regulatory interest in the land.
