My ex refuses to disclose his financial documents

I cannot provide legal advice, but only general information. You should ensure that your requests are detailed in writing. As for the threat of reducing work hours, this is one of the reasons it is important to also obtain previous years income information. The costs to address the medical issues may be section 7 expenses and therefore may require payments over and above the basic Table amount child support. However, there is no requirement to assist with your lost wages, gas and parking. I think you should consult with a lawyer of your choosing to fully canvass and explore all issues, and further to that meeting you may decide to commence litigation proceedings. Typically, litigation is advisable when one of the party's is not co-operating or complying with simple disclosure requests. Once proceedings are commenced, motions for third party disclosure is available, if necessary.
