How do you put a lien on people's property when you file a civil suit? Also, the petition state you can add a yearly interest?

While I'm not familiar with the law of Kansas particularly, generally you can't file a lien against someone's property unless you either have their permission (for example, when you take out a mortgage loan, you give the lender permission to place a lien on your home) or you have already obtained a judgment against them.  In rare cases you may be able to get a prejudgment writ of attachment against a defendant's assets, but there is nothing in your question to suggest that you can meet the requirements to get that relief in your case.
