Prenuptial agreements and sunset clauses in legal and royal contexts

Prenuptial agreements serve as legal tools to protect assets and define rights during marriage or divorce. In Florida, some couples utilize sunset clauses, which are provisions that cause an agreement, or specific parts of it, to expire after a set number of years or upon the occurrence of certain life events, such as the birth of a child.

In the context of the British Royal Family, Prince William reportedly chose not to sign a prenuptial agreement before marrying Kate Middleton in 2011. Sources suggest this decision was influenced by the public and tumultuous separation of his parents, King Charles and Princess Diana, as he sought to avoid a relationship defined by financial negotiation.
