Can a condo association take my condo after placing a lien?

Typically, yes, if it is a bona fide lien due to not paying your assessments or for a fine as a result of non-compliance with house rules. Note that laws vary from state to state, so it is a good idea to talk with an association-savvy attorney in your area for more info on your state's laws.

Try to work out a payment plan with the condo association if you are in financial trouble. Your mortgage company might also be able to help. Note, however, that they may declare your loan in default for not paying your assessments.
