In Illinois after a lien is place on a bank account can you still deposit money in the account and will that be attaced to the lien or can you use it.

It depends on how the writ of execution was worded. Some writs will specify a one time attachment of the balance, others may specify an ongoing attachment until the bill is paid. You need to get a copy of the writ to see.

Also the judgment holder can keep filing new writs if they are limited to the balance.

P.S. Please be more careful in your choice of topic. I've move3d this from the Children forum since it has nothing to do with that topic.
