Wyoming mobile home — quick answer
Wyoming titles are county business, handled by the clerk in the county seat rather than a state office. For a mobile home there is an extra condition attached: the taxes for the preceding and current year have to be certified as paid before a certificate of title will issue at all.
How mobile home sales actually work in Wyoming
- Where titles are processed
- The county clerk in the county seat of the county of residence
- Tax condition
- All taxes due for the preceding and current year must be certified as paid before a title is issued
- Relinquishing the title
- MV-303, Mobile & Manufactured Home Affidavit, when the home is on a permanent foundation and taxable as real property
- Where MV-303 is filed
- In the county where the home is located, with the title fee where applicable and a recording fee
- No title available
- MV-141, Transitional Ownership Document
- Transfer on death
- Each county clerk provides a beneficiary designation form, recorded with the clerk of the county where the home is titled
Transferring a mobile home in Wyoming, step by step
- Work out the tax position early. Wyoming will not issue a title on a mobile home until the preceding and current year taxes are certified paid, and the seller is usually the one who has to clear them.
- Take the transfer to the county clerk in the county seat where the buyer lives, not to a state motor vehicle office.
- If the home sits on a permanent foundation and is taxed as real property, MV-303 relinquishes the certificate of title instead.
- Where no title can be produced, ask the clerk about MV-141, the Transitional Ownership Document, before assuming the sale can proceed.
What private buyers get wrong here
- Unpaid prior-year tax stops the title outright. Agree in writing who is clearing it, because the buyer is the one left unable to title.
- A home already relinquished under MV-303 is real property and moves with the land, so there is no title left to assign.
- County clerks run this, and practice varies between counties. Call the specific county seat rather than relying on what another county did.

Is a mobile home bill of sale required in Wyoming?
Wyoming titles are county business, handled by the clerk in the county seat rather than a state office. For a mobile home there is an extra condition attached: the taxes for the preceding and current year have to be certified as paid before a certificate of title will issue at all.
Does a Wyoming mobile home bill of sale need to be notarized?
Check the signing requirements for the specific title and bill-of-sale form. Notarization of a title assignment and notarization of a bill of sale are separate questions; a car rule does not establish the rule for this item.
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.
