Contractor liens

[Andrew S.]

I hired a general contractor to do a fairly major rehab on one of my properties.  Construction is done but it now turns out that the GC apparently has not paid some of the subs yet and they threaten to file contractor lien against my property.

Questions:

1. How will I know if a lien has been filed (will I be notified or do I have to do periodic title searches?

2. What are my options for resolution and potential action to take against the GC and/or the sub who filed the lien?

Any input appreciated.
