Child Support, Medical Service Liens, and pinning these to a trustor.

I have 2 questions while doing property record search. 1. Sometimes I saw child or family support judgments as well as county medical service liens recorded under the same name of my targeted trustor. A medical service lien has the debtor’s signature which can be compared with the trustor’s signature in a deed of trust. But a child/family support judgment has only social security number, driver license, or date of birth. How do I know it belongs to the trustor or somebody else with the same name? 2. Is notory bond a lien? Thanks!

This can be a challenge. Try to correlate whatever you can. Otherwise you just have to make a judgement call.
