Washington Petition For Legal Separation (Registered Domestic Partnership) is a legal document that establishes the legal separation of domestic partners in Washington State. The Petition must be filed with the court and signed by both parties in order to be legally binding. The Petition includes the names of the partners, their addresses, the date of the legal separation, and any terms or conditions that the parties have agreed to regarding the separation. The Petition can also cover such issues as division of property, spousal support, and child custody.
