Does Virginia require a step parent to pay child support if he raised the child and was a parent in loco to the child

No.  Unless that person adopted the child, only natural or adopted parents are legal obligated to pay child support.  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.
