Conflict of laws

Conflict of laws or Private international law (both terms are used interchangeably)[1] concerns relations across different legal jurisdictions between persons, and sometimes also companies, corporations and other legal entities.[2][3]

Choice of laws

Courts faced with a choice of law issue have a two-stage process:

  1. the court will apply the law of the forum (lex fori) to all procedural matters (including, self-evidently, the choice of law rules); and
  2. it counts the factors that connect or link the legal issues to the laws of potentially relevant states and applies the laws that have the greatest connection, e.g. the law of nationality (lex patriae) or domicile (lex domicilii) will define legal status and capacity, the law of the state in which land is situated (lex situs) will be applied to determine all questions of title, the law of the place where a transaction physically takes place or of the occurrence thatave rise to the litigation (lex loci actus) will often be the controlling law selected when the matter is substantive, but the proper law has become a more common choice.

Private international law on marriages and legal dissolutions of marriages (divorce)

In divorce cases, when a court is attempting to distribute marital property, if the divorcing couple is local and the property is local, then the court applies its domestic law lex fori. The case becomes even more complicated if foreign elements are thrown into the mix, such as when the place of marriage is different from the territory where divorce was filed; when the parties' nationalities and residences do not match; when there is property in a foreign jurisdiction; or when the parties have changed residence several times during the marriage.

Whereas commercial agreements or prenuptial agreements generally do not require legal formalities to be observed, when married couples enter a property agreement, stringent requirements are imposed, including notarization, witnesses, special acknowledgment forms. In some countries, these must be filed (or docketed) with a domestic court, and the terms must be “so ordered” by a judge. This is done in order to ensure that no undue influence or oppression has been exerted by one spouse against the other. Upon presenting a property agreement between spouses to a court of divorce, that court will generally assure itself of the following factors: signatures, legal formalities, intent, later intent, free will, lack of oppression, reasonableness and fairness, consideration, performance, reliance, later repudiation in writing or by conduct, and whichever other concepts of contractual bargaining apply in the context.

Private international law on unmarried persons

Unlike marriage which has an international recognised legal status, there are no international treaties on recognition of unmarried couple's legal status. If an unmarried couple change residence to different countries, then the local law on where the couple is last domiciled is applied to them. This covers legal status of the relationship, rights, obligations, and all worldwide movable and immovable property. To otherwise interpret the law would mean if the unmarried couple had assets in several different countries, they would then need separate legal cases in each country to resolve all their movable and immovable property.

In the absence of a valid and enforceable agreement for an unmarried couple, here’s how the conflict of law rules work:

  • Full Mutability Doctrine - property relations between the unmarried couples are governed by their latest domicile, whether acquired before, during or after the relationship.


Many contracts and other forms of legally binding agreement include a jurisdiction or arbitration clause specifying the parties' choice of venue for any litigation (called a forum selection clause). Then, choice of law clauses may specify which laws the court or tribunal should apply to each aspect of the dispute. This matches the substantive policy of freedom of contract. Judges have accepted that the principle of party autonomy allows the parties to select the law most appropriate to their transaction. This judicial acceptance of subjective intent excludes the traditional reliance on objective connecting factors; it also harms consumers as vendors often impose one-sided contractual terms selecting a venue far from the buyer's home or workplace.

Harmonization of laws

To apply one national legal system as against another may never be an entirely satisfactory approach. The parties' interests may always be better protected by applying a law conceived with international realities in mind. The electronic commerce and defamation issues. There is a general recognition that there is a need for an international law of contracts: for example, many nations have ratified the Vienna Convention on the International Sale of Goods, the Rome Convention on the Law Applicable to Contractual Obligations offers less specialized uniformity, and there is support for the UNIDROIT Principles of International Commercial Contracts, a private restatement, all of which represent continuing efforts to produce international standards as the internet and other technologies encourage ever more interstate commerce. But other branches of the law are less well served and the dominant trend remains the role of the forum law rather than a supranational system for Conflict purposes. Even the EU, which has institutions capable of creating uniform rules with direct effect, has failed to produce a universal system for the common market. Nevertheless, the Treaty of Amsterdam does confer authority on the Community's institutions to legislate by Council Regulation in this area with supranational effect. Article 177 would give the Court of Justice jurisdiction to interpret and apply their principles so, if the political will arises, uniformity may gradually emerge in letter. Whether the domestic courts of the Member States would be consistent in applying those letters is speculative.
