If the sub who did not file the lawsuit did not extend the lien, that lien is deemed extinguished by operation of law. The title company should not longer care about it and you should be able to get your money back from escrow pertaining to that lien. As for the sub who filed the lis pendens and lawsuit, you should be in the process of fighting that case. Do you have a defense? Did the sub contract with you or with a GC? If a GC, did you bring the GC into the lawsuit for a claim over? Need more info.
There are a LOT of issues raised by this question. First, if you are in litigation you should speak to your attorney about these issues. If litigation is pending and you don't have an attorney that is the first thing you might want to think about changing. Second, in very general terms, bonding a mechanic's lien is not going to "get your money back" because the bond will cost money itself. Most title companies will require 200% be put up in escrow. None will take less than 100%. So the question is how much did this title company require? The bond would be for 110% plus annual premiums and then you have to get the discharge in the Court so all in all the bond may get you a bit back if the title company is holding say more than 120%. Next, if you bond a mechanic's lien the lienor is not permitted, by law, to extend the LP. In fact, pursuing an LP when a mechanic's lien has been bonded is prohibited and can get the lienor in trouble. Finally, as for the lienor that did not show up, the lien was kept alive by the filing of the LP by the foreclosing lienor. You could pursue a motion to dismiss because failure to foreclose is deemed a waiver but most, if not all, title companies will require a court order discharging the lien in this situation before they will release the funds from escrow. Bottom line - speak to your attorney about this ASAP.
