Illinois Mobile Home Bill of Sale — FAQ
Is a mobile home bill of sale required in Illinois?
A bill of sale is recommended in Illinois. There is no official state bill of sale form; the assigned title transfers ownership and a tax form reports the sale.
Does a Illinois mobile home bill of sale need to be notarized?
No. No notarization required.
Do I need a bill of sale to sell a mobile home?
In most cases, yes. A mobile home bill of sale documents the price and terms and supports the title transfer. If the home is titled as personal property you will also sign over the title; if it has been converted to real property, the sale is handled more like real estate.
Is a mobile home titled like a car?
Often, yes — when classified as personal property, a manufactured home is titled through the state motor-vehicle agency, similar to a vehicle. Once permanently affixed to land you own, it may be converted to real property and recorded with the county instead.
Is a bill of sale proof of ownership?
Generally no. For titled property like a car or boat, the title is what proves ownership. A bill of sale proves that a sale happened and records the price, date, and terms — it supports the title transfer but does not replace it. For untitled property (furniture, equipment, electronics), the signed bill of sale is usually the main proof of ownership.
