Legal Question in Family Law in Washington

You can download the forms from the Washington Courts' website: http://www.courts.wa.gov/forms/.

You prepare a Parenting Plan that reflects what you want to do for residential time.

As to whether that will save you money in the long run, it will depend on how well you understand and use the forms and how much you understand about how you can adjust the provisions to your purposes. I have seen many people save $1500.00 by doing it themselves and spend $5000.00 to fix it later.
