If you are talking about "Avoiding the Lien," you wil need to file a motion in your bankruptcy on this topic. If the Bankruptcy case has been closed, you will have to reopen it in order to "Avoid the Lien." Notice & service of this motion is complex, so I would make sure your attorney is familiar with this type of motion. It will be helpful to have a copy of the lien paperwork from the county recorder's office.
You would think that the creditor would be willing to remove their lien voluntarily since the courts almost always grant the request to avoid the lien, but my experience is they never will.
If you have a legal dispute with a lien, you can contest or challenge a lien under notice as described in Fla. Stat. 713. They lien holder will have 60 days to respond and/or litigate the issue. Another approach is to bring a slander/quiet title action to prove clear title. There is a chance that the bankruptcy did not discharge the secured creditor in the bankruptcy. That is something that would require some research.
Discharge does not remove the lien. You either need to file a Motion to Avoid the Lien (if it was involuntary) OR file an Adversary Proceeding in Chapter 13 to remove a mortgage.
