I am losing my job at the end of this month, is my ex-husband obliged to pay more child support for our minor child?

Yes, this should affect the child support calculation and, yes, you will need to petition the court for a modification. This answer is given in accordance with the laws of Virginia and may not be applicable in any other state.  It should not be construed as legal advice, as that would require a more thorough analysis of all of the facts involved in a specific case.  If you need further information or assistance, please feel free to contact my office for a consultation. Case results depend upon a variety of factors unique to each case. Case results do not guarantee or predict a similar result in any future case.
