Prenups are legally binding on both parties unless the terms are unconscionable. Prenups provide numerous benefits for women in particular. Some of the most important prenup considerations for women include: protection of separate property, spousal support, protection of inheritance, business or professional assets, and life insurance. You can customize your prenup to suit your specific needs and financial situation. Many couples use prenups to protect separate property, outline spousal support, and set guidelines for the division of assets.
