My husband wants to file to establish custody of his 11 year old son. His son was born in Riverside County California and resided in the state and county prior to his mother moving to Texas after she got married in 2008 in California. When she first moved, my husband was unaware of his right to keep his son in California. Since her move, she has continuously threatened to keep his son away from him without reasoning other than because she just wants to. They had a verbal agreement that we would have him in the summers in California until the summer of 2013 she refused to send him 2 months after we purchased his plane ticket. We were finally able to convince her for the summer 2014 to send him so he currently in our care in California. After he arrived she again advised that she will not allow us to see him without a court order. How can file the documents without an attorney and if we have to file in Harris or Riverside County. There have been no prior court proceedings in either state
