Domestic relations cases generally do not qualify for pro bono representation. However, there are a few low-cost alternatives:
You could contact the Oregon State Bar's Modest Means Program and ask to have an attorney from your area referred to you. The website is http://www.osbar.org/public/ris/ris.html. The phone number is 503-684-3763 or toll-free in Oregon at 800-452-7636.
Also, you might want to contact the Legal Aid Office in Jefferson County and ask whether they take domestic relations cases. They can be reached by phone at (541) 385-6944 or 1-800-678-6944 and information can be found online at http://www.osbar.org/public/ris/LowCostLegalHelp/LegalAid.html.
My responses to posts on AVVO are not legal advice, nor do they create an attorney-client relationship. In order to provide true (and reliable) legal advice, an attorney must be able to ask questions of the person seeking legal advice and to thus gather the appropriate information. In order for an attorney-client relationship to exist, you and I both have to agree the the terms of such an agreement.
