How do Evicting a adult child in Texas?

You can certainly give him a 30 days notice, with intent for him to vacate your home at the end of the thirty days. List your reasons why you are evicting him. The 30 days gives him ample time to fine a job and a place to live. No one says you are responsible for him now that he is an adult. Wants to be an adult but not live up to the responsibilities. A real common problem. IF, for some reason, he does not improve in the 30 days, you have every right to kick him out. Take his things, move them out, change the locks, and close whatever account you and/ro your wife have your names on for him.

He does not like authority, so let him be his own authority, in his own place, not yours.
Good luck.

thanks for the answer, yes I've given my son so many chances to get things together but he just doesn't get the picture. Maybe his mindset will change if he was on his own and reality hits him. So its it best to go through the eviction process through the courts or can I just throw him out? Thanks

You can consult an attorney or your local sheriff about your best way to do this. I can tell you, from experience, what my parents did to my mooching older brother when they finally had enough of trying to help him get on his feet. Mom packed his things, Dad took them down to where he worked and put them in the back of his car, then Dad changed the locks on the house and garage. My younger brother and I were given strict instruction to not allow our brother back in - but no instructions were needed - we knew he had to go.

When my parents kicked me out, because I had a major disagreement with them about my then boyfriend, it actually was the best thing they could have done for me. I needed to wake up. It was too easy being at home. I needed to grow up and learn what it meant to be an adult. I was not even allowed my clothes - just what I wearing and the $20.00 I had in my purse. I think the speech went something like this, "If you think you know it all, then get the h*** out."

Your son is not a minor and therefore your responsibility for him is over, in that sense. You are not being cruel, you are trying to get back your home and security. I would say to throw him out - give him the notice (don't see why you need a court process) and then follow through. Following through may be tough but do it. Stand firm. Good luck.
