In joint ownership of a mobile home, your rights are set by the form of co-ownership printed on the certificate of title. That one line decides whether you can sell your share without asking, whether the home passes automatically to the survivor when a co-owner dies, and whether a creditor of one owner can reach the home. Everything else, from who pays the lot rent to how a buyout works, lives in a separate written agreement between the owners.
Why the Title Is the Document That Matters
Most states treat a mobile home as personal property, closer to a car than to a house. Ownership is proven by a certificate of title issued by a state agency, often the department of motor vehicles, rather than by a deed recorded at the county. The classification only changes if the home is permanently attached to land the same person owns and the owner files to convert it to real property. Until that happens, the home and the land underneath it are legally separate assets.
Because the title controls, the words written on it when the home is purchased or re-titled are what matter. If no specific ownership form is stated, most states default to tenancy in common. That default rarely matches what co-buyers actually want, so it pays to be deliberate at the counter.
The Three Forms of Co-Ownership
Tenancy in Common
Tenancy in common lets co-owners hold unequal shares. One person can own 70% and the other 30%, and both still have the right to use the entire home. Each owner’s share is independently transferable. You can sell it, give it away, or leave it to someone in your will without the other owner’s permission. There is no right of survivorship, so when one owner dies, their share passes through their estate, not to the surviving co-owner.
Joint Tenancy With Right of Survivorship
Joint tenants acquire their interests at the same time, from the same document, in equal shares, with equal rights to possess the whole property. The defining feature is survivorship. When one joint tenant dies, that person’s share passes automatically to the surviving owner, bypassing probate. The surviving owner files a death certificate with the titling agency and receives a new title in their name alone. Because the transfer happens by operation of law, it overrides anything the deceased’s will says.
One trap worth knowing: if a joint tenant sells or transfers their share during their lifetime, the joint tenancy is usually severed and converts to a tenancy in common between the original owner and the new buyer. Survivorship disappears at that point.
Tenancy by the Entirety
Tenancy by the entirety is available only to married couples, and only in states that recognize it. It works like joint tenancy with survivorship and adds stronger creditor protection: in most states that allow it, a creditor of just one spouse generally cannot force a sale of property held this way. Not every state extends tenancy by the entirety to personal property like mobile homes, so married couples should confirm their state allows it for titled personal property before relying on the protection.
What Happens When a Co-Owner Dies
The ownership form on the title is what actually controls inheritance. With tenancy in common, the deceased owner’s share becomes part of their estate and passes under their will, or under state intestacy law if there is no will. The surviving co-owner could end up sharing title with an heir they have never met, and that new co-owner has the same right to use, occupy, or demand a buyout. This outcome regularly surprises people who assumed co-ownership meant the survivor would inherit.
Joint tenancy and tenancy by the entirety eliminate that risk. The share is absorbed by the surviving owner immediately at death, no probate, no court order. The survivor contacts the titling agency, presents a certified death certificate, and the title is reissued.
Tax Exposure You Should Know About
Three federal tax rules reach into joint ownership: gift tax when you add someone to the title, estate inclusion when a co-owner dies, and the basis adjustment that affects capital gains if the home is later sold.
Gift Tax When Adding a Co-Owner
Adding someone’s name to a mobile home title for less than fair market value is a gift to the IRS.1Internal Revenue Service. Gifts and Inheritances If you own a mobile home worth $50,000 and add your adult child as a 50% co-owner without receiving payment, you have made a $25,000 gift. The annual gift tax exclusion for 2026 is $19,000 per recipient, so the first $19,000 is excluded. The remaining $6,000 must be reported on IRS Form 709, though you will not owe actual tax unless you have already used up your $15 million lifetime exemption.2Internal Revenue Service.

Transfers between spouses are different. The unlimited marital deduction means adding your spouse to a mobile home title is not a taxable gift at all, regardless of the home’s value.3Office of the Law Revision Counsel. 26 U.S. Code 2523 – Gift to Spouse
Estate Inclusion at Death
For spouses who hold the home as joint tenants or tenants by the entirety, exactly half is included in the deceased spouse’s estate regardless of who paid for the home. For non-spousal joint tenants, the IRS applies a contribution test: the full value is included in the deceased’s estate unless the survivor can prove they contributed their own funds toward the purchase. If the surviving co-owner paid 40% of the original price, only 60% of the current value is included in the deceased’s estate.4Office of the Law Revision Counsel. 26 U.S. Code 2040 – Joint Interests
Stepped-Up Basis
Property included in a deceased person’s estate generally gets a basis step-up to fair market value at the date of death.5Office of the Law Revision Counsel. 26 U.S. Code 1014 – Basis of Property Acquired From a Decedent For a married couple holding a mobile home as joint tenants, half the home gets a stepped-up basis when the first spouse dies. The survivor’s half keeps its original basis. If the survivor later sells at a profit, the gain on the original half is measured from the original purchase price and the gain on the inherited half from the stepped-up value.
Loans and the Due-on-Sale Risk
If there is still a loan on the mobile home, adding a co-owner to the title can create a problem. Most chattel loans, the type of financing used for mobile homes classified as personal property, include a due-on-sale clause that lets the lender demand full repayment if ownership is transferred. Adding a new name to the title counts as a transfer.
The Garn-St. Germain Act specifically covers loans secured by a residential manufactured home and prohibits lenders from accelerating for several types of transfers:6Office of the Law Revision Counsel. 12 U.S. Code 1701j-3 – Preemption of Due-on-Sale Prohibitions
- Transfer to a surviving joint tenant by operation of law at death.
- Transfer to a spouse or children.
- Transfer to a former spouse under a divorce decree or property settlement.
- Transfer into a revocable living trust where the borrower remains a beneficiary.
These protections do not cover every situation. Adding a friend, a business partner, or an unmarried partner to the title is not on the list, and the lender could call the loan due. Contact the lender before changing the title and get written confirmation that the transfer will not trigger acceleration.
Shared Bills and Liability
The title says who owns the home. It says nothing about who pays. If the home sits in a manufactured home community, the lot lease often makes all named tenants jointly and severally liable for the full rent. The park can pursue either co-owner for the entire amount if the other stops paying. The same applies to utility accounts and insurance policies listing both owners.
Maintenance, property or personal property taxes, and insurance premiums should be split in writing. Without that, disagreements about who owes what tend to escalate, and the recovery options are slow and limited. Co-owners holding unequal shares as tenants in common often divide costs proportionally to ownership, but only if the arrangement is documented.
When Co-Owners Disagree
Co-ownership works fine until one person wants out and the other wants to stay. A tenant in common can sell their share to an outsider, but partial interests in mobile homes are hard to sell. The practical path is a buyout, with one owner paying the other for their share. The fight is almost always over value. A professional appraisal using comparable sales is the standard tool, and co-owners who agree in advance on a formula, such as the average of two independent appraisals, avoid the worst of it.
If no agreement is possible, any co-owner can file a partition action. For personal property like a mobile home, a court will typically order a sale rather than physically divide the asset, with proceeds split by ownership share. Partition is expensive relative to the value of most mobile homes, and the legal fees can consume a meaningful share of the sale proceeds, which is why it is a last resort.
The Written Agreement That Backs Up the Title
The title establishes ownership. A separate co-ownership agreement covers everything the title cannot. A workable agreement addresses:
- Expense sharing: lot rent, insurance, taxes, repairs, and utilities.
- Use and occupancy: who lives in the home, whether it can be rented out, and what happens if one owner wants to move in and the other does not.
- Buyout process: how value is set, how long the remaining owner has to arrange financing, and what happens if neither can afford the buyout.
- Decision-making: who approves major repairs or improvements, and how disagreements get resolved before litigation.
- Default provisions: what happens if one owner stops paying their share, including whether the paying owner builds additional equity or can force a sale.
The agreement should be signed by all co-owners and notarized. It does not replace the certificate of title; it works alongside it. Co-owners who skip this step are betting they will always agree on everything, and that bet rarely holds over the life of a home.
