Prenuptial & Cohabitation
While no one enters a relationship expecting it to end, preparing for the “what-ifs” is a responsible step—especially when significant assets, children from previous relationships, or inheritances are involved. Prenuptial agreements and cohabitation agreements are legal tools that help couples define financial arrangements, protect individual interests, and avoid future disputes.
A Prenuptial Agreement is created before marriage, setting out what should happen to property, assets, and finances if the marriage ends. A Postnuptial Agreement does the same but is made after the wedding. These are increasingly common among business owners, high-net-worth individuals, or those entering second marriages.

Cohabitation Agreements are designed for unmarried couples who live together and wish to clarify how assets, income, and shared responsibilities are managed. Unlike married couples, cohabiting partners don’t automatically gain legal or financial rights—making formal agreements even more important.
