If it is just an notice to lein, that is not that uncommon a practice for costruction Companies. In effect, it puts a legal claim on your home, that must be satisfied before the property can close at sale or at refinance. It's a good legal tool that protects a subcontractor in a case like this. This is just my opinion, and not my legal advice to you.
I would encourage you to get professional, legal advice in your local area immediately, and to always do so as soon as possible wheever you get a notice like that from anyone. best of luck to you...
That is true. In Colorado a "Notice of Intent To Lien" must be given the property owner before an actual lien can be filed. A lien must also be filed within a statutory time period from when the work was done. (three months if I remember correctly) After the lien is filed it can be foreclosed. I did that once with a deadbeat company that was developing a subdivision and owed me quit a bit. They ignored the lien but boy did the foreclosure suit get their attention. I was paid within a few days.
Oh, someone said something about Homestead laws. Odds are that you waived any homestead rights when you signed your paperwork for your mortgage.
