If a condo management company places a lien on your condo will you be locked out of it?

First, the conodminium association placed the lien, the management company just did the paperwork. A lien is placed on your condo to make sure you can't sell it without the back debts being paid. It is done to protect the association. This is usually done when assessments aren't paid on time. If you have fallen behind on your payments, then the association can withhold certain services, possibly even turning off utilities (depending on your documents and state law), but can't lock you out of your home. They can, however, foreclose on your unit if assessments continue to go unpaid.
