Friend of mine in divorce can't get his soon-to-be-X to agree to sell house. What to do?

A friend and his spouse filed for divorce in Pennsylvania over 2 years ago, leaving the wife in the home. More than one year ago, the court recommended the marital home be put up for sale "as soon as possible". The spouse residing in the home does not want to sell. The court re-issued their recommendation, so now the house is up for sale, but the price is too high. The realtor recommended a lower price that is closer to the appraised price (house had a full appraisal). The house is priced more than $35,000 more than the average price of similar style homes in the same development currently on the market. The resident spouse refuses to accept a penny less than asking price, and already turned down a fullprice offer that had a $10,000 seller ist on it. To make matters worse, the resident spouse does not work and was living off my friend's alimony payments. He just lost his job through a retirement work-force reduction program, has no savings, and his pension is much less than the required alimony payments. So the house really needs to be sold before they can't make mortgage payments and have the house go into a default situation. He already has a court date to seek to have his support payments lowered but that date is a couple months off. In the meantime, what can he do to have the resident spouse accept a good offer that was over the appraisal value of the house? She also has been staying in the house when it is being shown, and agents are indicating that she is being pushy, following them around in the house, bragging about how good the house is and that the price is not negotiable. One agent even put it in writing that she scared his buyer off. What can be done about that?
