Legal Question in Real Estate Law in Utah

Re: Getting tenants to leave the premises

You gave them 30 days notice, which is all that is required. Now send them a "3 day notice to quit" meaning they have 3 days to get out. On the 4th day you can file with the court to have them forcibly removed. This is a process called unlawful detainer. You will need an order from the court for a sheriff to remove them from the apartment.

Your son-in-law is absolutely wrong. If he is renting the basement, he has no rights to the upstairs. Have your husband return with an officer or deputy. If your son in law objects, the police can keep him in check.

Do not let them intimidate you. Regardless of the fact that this is a family matter, you should stand firm. At some point in life they need to learn to be responsible. From your facts, it can be inferred that they are not being responsible with other aspects of their life. This may be a time for "tough love." You can be pleasant, but firm.

I would recommend hiring an attorney. They you can tell your daughter that you are just following the advice of the attorney, because you have to sell the house. That will help avoid a face to face confrontation. Tell them to deal with your attorney. You may also want to consider finding them a place (inexpensive) to live and paying one month's rent. That may be less expensive than hiring an attorney. Don't sign or pay for more than one month's rent though.
