How do I make a live-in caregiver move out?

One thing to consider, if you don't contact the police she will have a clean record when she applies to work for the next person.

First, I'd report her stealing from you and pawning it to the police so that they will arrest her.

Second, I would evict her.

I think this is dicey territory with the usual laws in place protecting tenets rights - 30 day eviction notice and such. She could do a lot of damage in 30 days.

Hopefully, you have actual evidence of her stealing. This may be your best way around the situation. If you have proof then you can file a police report and she would be arrested. Then - you would be able to apply for a restraining order- keeping her away from your wife, your property and you.

Once she has been charged there is no guarantee she would be put in jail or if put there - doesn’t make bail. Hence, the need for the restraining order. But do work with the police to arrange a time for her to be escorted to your home to collect her personal belongings.

I'd tell her yes, I will do that and I will deduct $78 from your paycheck and I want you to leave.

I think you just answered ur own question. She confessed. I would think the next thing you'd say is thank you for confessing but I can't keep you on. Also, the pawn shop received stolen goods. Their loss. I would file a police report for ur protection. A lawyer may be good. Maybe u can deduct the cost from her last check. Make a deal that you won't press charges if she leaves quietly with no references. Get everything in writing.

Have the home tented for termites, fire her. Don't have her come back, showing a copy of the police report. Be sure to pay her two weeks in lieu of notice.
Be sure to have her sign a forwarding address, give it to you to give to the post office as she gives you the key, as you say you will mail her pay to that address today.
Change the locks.
Inform the necessary neighbors if needed.

This is the OP. My proof that the caregiver has been stealing is that today she confessed to me, gave me the pawn tickets, and asked if I would go redeem my own stuff from the pawn shop. I may do it, because paying $78 to get my lawnmower back is way cheaper than buying a new one.

You will have to evict her, 30 days notice in most places. I hope you were paying her something in addition to room and board. It may come back to haunt you.

Lie and say your niece is coming to live with you and she will be doing her job. Give her two weeks notice and pay her 2 weeks more pay. Also, offer to pay for a hotel for 2 weeks. Contact her employer (if she works through an agency) and explain your niece will be coming and she will loose her job. Change the locks immediately.
Personally, I don't think she's going to go through the whole effort of filing against you when she's guilty of stealing from you and that's hanging over her head.

The police would like to hear that story. A pawn shop cannot receive stolen property.

What is the thief going to do with your belongings when you leave to the pawn shop?
Sounds like a drug addict's sad sob story, imo.
It is not exactly repentance if you have to pay. Maybe only an emotional con in order to stick around?

You have kept her working there?  You hate to lose her?
A simple call to 911 would have done it.

So sorry for you and your family.

What have you been paying her anyway?  Maybe it is not enough?

Anyway, don't think that you really need advice anymore.
