I reside in California, and last year the court ordered my ex to reimburse me for some expenses that we were supposed to split as per court order. On top of that they also granted me reimbursement of back child support paid by retro-actively changing the child support order tyo remove my son who I had obtained custody of. The court documents stated that she was to pay me for these out of the proceeds of the sale of our house. However, she stopped paying for the house, it was foreclosed on, and just recently sold at auction. Since there are no proceeds from the house, and the court documents said the amountd would be due and payable if the proceeds were insufficient, I was advised to withhold what she owes me from her support payments. I currently pay around $800/mo, and she owes me a total of approximately $4K. Can I withhold the whole payment until the debt is satisfied or do I have to pay her at least part of it and withhold part of it from each payment?
