Will a prenup protect me from my wife’s debt?

My girlfriend and I are due to be married in a few months and I am thinking about asking her to sign a prenup. I discovered recently that she has a lot of debt – credit cards, a student loan, and back property taxes for a house she owns in Memphis. I’m worried that once we get married, if she doesn’t stay current with her payments the creditors may come after me. Are prenups legal in Tennessee and will a prenup keep me from being responsible for her bills after we get married? I’d also like to know how I find a lawyer near me who has a lot of experience with prenups.
