Warrant in Debt - Credit Card - Lien?

Hello All, thanks in advance for your help/advice.

I've unfortunately been unemployed for a number of years and have gone through my savings. I am the father of 3 small children.

I have racked up huge credit card debts. One, with Citibank, is over $13K.

Just got a "Warrant of Debt" to appear in court, not issued by Citibank it looks like but what appears to be a law firm or debt collection firm.

Anyway, bottom line is that I really do owe this money and fully intend to pay this off somehow.

My question: Since this is a Credit Card debt, can they put a lien on any real estate property I am part owner of on paper?

I inherited some real estate when my parents passed, which I co-own on paper with my siblings, and my share has already been willed to my three children, at this stage the only thing I can really give them of financial value if I suddenly drop dead. And I do not want my debtors to be able to touch it for that reason, obviously.

So, the question again, since this is a CREDIT CARD debt, in light of this Warrant in Debt court summons, is my (and hence my kids') RE property share at risk of getting tainted with a lien.

Thanks again for your help, advice and time.
