Under Pennsylvania law an agreement to live separate and apart is controlled by contract law. If you and your spouse are no longer living together or if you are contemplating a separation, you need to protect your rights.
This can be accomplished by a written agreement between you and your spouse. Such an agreement can be as simple or as complex as is necessary to protect you and your property.
