I banned a former friend from my house for life. If he ever shows up, can I use the police to make him leave?

Generally yes, you can prevent him from entering your property or legally demand that he leave. If he does not, you may call the police. At least in Texas and likely in other states, the police will force him to leave or arrest him. After that how it is prosecuted (if it comes to that) depends on how the district attorney in your jurisdiction handles such things. Some counties are very liberal on this issue.

I have a "friend" who bought parts of a collection I had. He intended to buy much more over time as he got the money. Since I had known him a while--we both worked in law enforcement--I figured it was okay to let him take the rest of the collection and pay me back over time. Well, he didn't. I knew where he worked, all his friends, had his phone number, and so on but he avoided me when possible. It's unfortunate to know there are people out there who will use others for whatever they can. I still trust others generally, and trust other friends, but still I'm more cautious now.

We expected this type of nonsense from the inmates we sometimes monitored. I didn't expect it from him.

am not sure he will show up anyway, if he hasnt all this while he probably never will. dont worry you wont need to call the police. sell off all his stuff or give it away and move on

If you have his property, you have to return it to him. If you loaned him money, you can't keep his property as compensation without going to court unless he agrees.

If he has property in your residence, he can show up with the police to remove it.

As for trespass, it helps to send him a formal letter telling him he is not allowed on your property to his last known address. You have to tell him that he has 30 days to collect his property and then you can sell it to cover the cost of the laptop. Once he is notified in writing, then you can call the police on him. However, what if he is showing up to pay you?

But I'm curious why you want a four year old laptop that isn't going to be worth more than a doorstop?

you could get him for trespassing probably, and if it continued to be a problem you might be able to get a restraining order

Take him to small claims court, if he shows up. if he gives you trouble, get a restraining order.

After 4 years, even Judge Judy would say it was O.K. to sell his stuff. Do you know any of his family members you can talk to, to locate him. If he shows, tell police of a trespasser on your property.

NEVER loan money to friends or family if you actually expect to get the money back. That is just not how it works, unfortunately. I think this situation is largely on you - you never should have expected to loan money and get it returned like that.

Now that you have loaned money, make a decision... Is a stupid laptop really worth loosing the friendship??

My advice would be to just count your losses, and remember to never loan money like that again. You know he doesn't have the money to repay you, why create a huge battle over something you should have known would play out the way it did?

The police have better things to do. Buy a gun.

You could if you have a restraining order against him.

Yes, you call and have him / her removed for trespassing.

yes
