When you live with your unmarried significant other, having a Cohabitation Agreement or Separate Property Agreement is an essential part of your estate plan. Unlike married couples, unmarried partners do not automatically have legal rights to each other’s property, which can create uncertainty and disputes if one partner passes away or the relationship ends. A well-drafted agreement clearly outlines each person’s ownership, financial contributions, and what happens to the property under different circumstances, ensuring your wishes are respected and reducing the risk of costly conflicts. By including such an agreement in your estate plan, you protect both your investment and your partner, while bringing peace of mind and clarity to a relationship built on trust.
