Recourse for Second Lien Holders during non-payment of loan?

[Account Closed]

I understand that if a borrower defaults on a 1st lien, then the lender can foreclose. However, what happens if the borrower defaults on a second lien? What recourse does the lender have in that situation? Do they just remain in default until the property is either 1.) sold or 2.) foreclosed on by the 1st position lien holder - all irrespective of the borrower coming current of course. Thanks!
