I read different state laws and they state this:
"The court-administered eviction process assures the tenant of the right to a court hearing if the tenant believes that the landlord has no right to evict the tenant. The landlord must use this court process to evict the tenant; the landlord cannot use self-help measures to force the tenant to move. For example, the landlord cannot physically remove or lock out the tenant, cut off utilities such as water or electricity, remove outside windows or doors, or seize (take) the tenant's belongings in order to carry out the eviction. The landlord must use the court procedures.
If the landlord uses unlawful methods to evict a tenant, the landlord may be subject to liability for the tenant's damages, as well as penalties of up to $100 per day for the time that the landlord used the unlawful methods."
States enforce these laws because it's wrong to turn off someone's utilities , esp. during winter when they are needed most or if the tenants depend on electricity to support medical devices, hence that's why it's illegal to use self-help measures and landlords can get into serious trouble if they use them.
On that note, there are agencies that help people cover rent expenses when they unexpectedly find themselves in situations like these. Tell her to visit WeConnect.net and local agencies that can help her.
