In Denmark prenuptial agreements are permitted. There is no requirement as to form or legal representation except that they must be in writing. They must be registered at a district court which then procures registration in a national register.
However, there is a trend for courts in Denmark to make awards in derogation of the terms of the prenuptial agreement if the contractual terms are unfair, especially if the marriage was lengthy and the contract removed all of the spouses' capital from the matrimonial community of property.
Our office has worked on several U.S. – Denmark prenuptial agreements, always collaborating with local counsel in all jurisdictions as appropriate.
Disclaimer: We are admitted to practice only in New York but work as appropriate with lawyers throughout all U.S. states and throughout the world.
