Evicting lease holders and their kids

[TRUNG DAO]

Hello,

I currently have both parents on the lease and the they have six kids that live with them(ages ranging from 21,20,18,17,16,14).  They have living there since the oldest was 15 year old.  In our contracted lease the parents are the lease holders and their kids listed as living with their parents.  This is for failure to pay eviction case.

The property is here in Texas and my questions are:

1>  Do I only need to file an eviction procedure to the parents(lease holders) only or every member that are currently living there?

2>  Is there a different procedure to handle this situation especially the  two minor?

Many Thanks in advance,

Josh
