Section 4.63(1) of the Civil Code of Hungary states that the purpose of a marriage contract is to allow the parties to a marriage, or the spouses, to establish a property regime—different from the default community property system—to govern their financial relationship during the marriage, starting from a date specified in the contract.
Subsection (2) further allows the parties to define different property regimes for specific assets. They may even diverge from the standard legal rules for statutory and optional property regimes, as long as such deviation is not explicitly prohibited by law.
To be valid between the spouses, the only formal requirement is that the agreement must be an “authentic agreement.” However, to be enforceable against third parties, the contract must be registered in the national registry of marriage contracts.
According to Article 28 of the Hungarian Act on Private International Law, the parties may choose which legal system will govern their matrimonial property rights. They may select the law of a state where one of them holds nationality, the law of a state where one of them has habitual residence, or the law of the country where the divorce proceedings will take place.
