This is a good one. Arlene, you must consult with your attorney to get a direct answer to your question. A lot depends on the terms stated in your contract.
If contract states that you are entitled to funds + purchaser agrees= funds may be released to you.
If contract states that you are entitled to funds + purchaser disagrees= funds may not be released to you.
An attorney is not able to release funds held in escrow, to either party, if there is a dispute over entitlement to said funds. The funds are placed with the court and the parties engage in litigation or reach a settlement.
There are other alternatives and considerations which are beyond the scope of this Q & A forum. Hope this helps a little. All the best.
