Judgement Lien Expiration

[Baeddan]

A judgement lien was placed on my California property in March of 1996.  I was not aware of it, it was relating to a business of my husband's.  We separated, he moved to Washington state and subsequently filed bankruptcy.  I followed suit and filed as well.  I filed a Ch 13 later to save the Calif property.  All the while unaware of the judgement lien.  I moved to Georgia in 2000, and sold the property to my son in 2002.  He discovered the judgement when he attempted to obtain a line of credit for his business.  I understand the judgement must be renewed after 10 years or it expires.  How do we determine if it has in fact been renewed or has truly expired?  If it has expired, how do we go about removing the lien?
