To add your son to your house title, you prepare a new deed naming him as a co-owner, sign it before a notary, and file it with the county recorder where the property sits. The paperwork itself is straightforward. The consequences are not. The transfer counts as a gift to the IRS, it usually costs your son the stepped-up basis he would get by inheriting, and it exposes the home to his creditors from the day the deed is recorded. Before you file, work through what the change actually does to your mortgage, your taxes, and your estate plan, and consider whether a transfer on death deed, a living trust, or simply leaving the home through your will would get you the same result with fewer problems.
Start With Your Current Deed
Pull your existing deed from the county recorder or your closing file. How ownership is held today controls what happens when your son’s name goes on it.
The two common forms of co-ownership are joint tenancy with right of survivorship and tenancy in common. Joint tenancy means the surviving owners automatically take the deceased owner’s share without probate. Tenancy in common gives each owner a separate share that passes through their estate at death, going wherever the will or state intestacy law directs. If you want your son to inherit the property automatically, joint tenancy does that. If you want him to co-own now but keep control over where your share goes at death, tenancy in common leaves you that flexibility.
While you have the deed out, look for tax liens, judgments, easements, or restrictive covenants. Unpaid liens generally need to clear before you can cleanly transfer an interest. Easements will not block the transfer, but your son should know they are there.
Check Your Mortgage First
If you still owe on the home, your mortgage almost certainly contains a due-on-sale clause letting the lender demand full repayment when ownership changes.1Legal Information Institute. Wex – Due-on-Sale Clause
Federal law carves out an exception for family transfers. The Garn-St Germain Depository Institutions Act bars lenders from enforcing a due-on-sale clause when “the spouse or children of the borrower become an owner of the property,” on residential properties with fewer than five units.2Office of the Law Revision Counsel. 12 US Code 1701j-3 – Preemption of Due-on-Sale Prohibitions So in most cases, adding your son will not trigger the clause, and the lender cannot call the loan due because of the transfer alone.
Notifying your lender is still smart. The servicer’s records should reflect the new ownership, and some will ask for a copy of the recorded deed. Note that adding your son to the title does not add him to the mortgage. He becomes a co-owner without becoming responsible for the payments.
Pick the Right Type of Deed
The deed is what actually transfers the ownership interest. Three types come up for family transfers, and they differ in how much they promise your son about the property’s title history.
Quitclaim Deed
A quitclaim deed is the simplest option and the most common choice within families.3Investopedia. Quitclaim Deed: What It Is and How It Works It transfers whatever interest you hold without making any promises about the quality of that interest. For a home you have owned for years with clean title, that is usually enough, especially if a title search confirms no surprises.
General Warranty Deed
A general warranty deed gives your son the strongest protection. You guarantee the title is clear of all encumbrances and that you have full authority to transfer it. If a defect surfaces later, even one that predates your ownership, you are personally on the hook to fix it.
Special Warranty Deed
A special warranty deed sits in the middle. You guarantee no title problems arose during your ownership but make no promises about what happened before you bought the home. It is a reasonable choice if you bought from a reputable seller and your years of ownership have been clean.
Record the Deed
Once the deed is signed and notarized, file it with the county recorder in the county where the property is located. Recording puts the ownership change on the public record and protects your son’s interest against later claims. Filing fees generally run somewhere between $10 and $80. Some states charge a transfer tax based on the property’s value, though many exempt parent-to-child transfers or transfers where no money changes hands. Call the recorder’s office before you go so you know what to bring and what it will cost.
The legal description on the new deed has to match the existing deed exactly. Even a minor discrepancy in a lot number or survey reference can get the filing rejected or create title problems later.
Understand the Tax Consequences Before You File
The tax side is where families get caught, and it is the strongest reason to consider an alternative before recording anything.
Gift Tax Filing
Transferring a partial interest in the home without receiving payment is a gift under federal tax rules. For 2026, the annual gift tax exclusion is $19,000 per recipient. If the value of the interest you transfer to your son exceeds that, you file a gift tax return on Form 709. You will not necessarily owe any tax. Amounts above the annual exclusion simply reduce your lifetime exemption, which for 2026 is $15 million per individual.4Internal Revenue Service. What’s New – Estate and Gift Tax Most parents will never reach that ceiling, but the return still has to be filed.
The Capital Gains Problem
This is the one that hurts. When you give property away during your lifetime, the recipient takes over your original cost basis. The IRS calls this carryover basis, and it means your son’s basis is what you paid for the home plus any improvements you made.5Internal Revenue Service. Publication 551 (12/2025), Basis of Assets If you bought for $150,000 thirty years ago and the home is worth $500,000 today, your son inherits that $150,000 basis. If he later sells for $500,000, he pays capital gains tax on the full $350,000 difference.
Property inherited at death is different. It receives a stepped-up basis equal to the fair market value on the date of death.6Office of the Law Revision Counsel. 26 US Code 1014 – Basis of Property Acquired From a Decedent Same numbers: if your son inherits at $500,000 and sells for $500,000, his taxable gain is close to zero. The gap between gifting and inheriting the same house can easily be tens of thousands of dollars in tax.
Possible Property Tax Reassessment
In some jurisdictions, a change in ownership triggers a reassessment of the property’s value for tax purposes. This matters most if you have owned the home a long time and the assessed value is well below current market value. Not every state treats a partial transfer to a child as a reassessment event, and several exempt parent-to-child transfers, but the rules vary enough that a call to the county assessor before recording is worth the ten minutes.
The Non-Tax Risks
Your Son’s Creditors Can Reach the Home
Once he is on the title, his ownership interest is an asset his creditors can pursue. If he carries significant debt, gets sued, or goes through a divorce, his share can be subject to a lien, a judgment, or a property division order. In extreme cases a creditor could force a sale. You cannot undo this after the fact unless he voluntarily deeds his share back.
Medicaid Look-Back
If there is any chance you will need Medicaid-funded long-term care in the next five years, transferring a property interest to your son can create an eligibility problem. Medicaid applies a 60-month look-back to transfers made for less than fair market value, and transfers inside that window trigger a penalty period that delays benefits. There is a narrow exception: if your son lived in the home for at least two years immediately before you entered a care facility and provided care that let you stay home rather than enter one, the transfer may be exempt from the penalty.7Office of the Law Revision Counsel. 42 US Code 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets Documentation requirements are strict and states apply them differently.
Conflicts With Your Estate Plan
Adding your son as a co-owner changes how the property passes at death, and that may not match your will or trust. Joint tenancy with right of survivorship sends the home directly to him outside probate regardless of what your will says. If you have other children or beneficiaries who expected to share in the home’s value, the result can be unintended disinheritance and family conflict. Have your estate planning documents reviewed before you change the title.
Insurance and Property Tax Exemptions
Call your homeowners insurance carrier after recording. If your son now has a financial interest in the home, the insurer may need to add him as a named insured or additional interest, and a policy that does not reflect current ownership can leave coverage gaps at claim time. Adding him can also affect senior or homestead exemptions you currently receive, depending on your state.
Alternatives That Usually Work Better
Because of the capital gains hit and the creditor exposure, many estate planning attorneys steer parents away from adding a child directly to the title. Three alternatives typically accomplish the same goal without those costs.
Transfer on Death Deed
About 29 states and the District of Columbia allow transfer on death deeds, sometimes called beneficiary deeds. You record a deed now naming your son as the beneficiary, but the transfer does not take effect until you die. In the meantime you keep full ownership and control. You can sell, refinance, or revoke the deed at any time. Because the property passes at death, your son gets the stepped-up basis instead of your carryover basis, and the home stays out of reach of his creditors until you pass away. Where available, this is often the cleanest solution.
Revocable Living Trust
A revocable living trust lets you transfer the home into a trust where you are both the trustee and the beneficiary during your lifetime. You keep complete control, and you can amend or dissolve the trust whenever you want. At your death the property passes to your son without probate, and he receives the stepped-up basis. A trust also gives you continuity if you become incapacitated, because a successor trustee can step in. The tradeoff is setup cost. The Garn-St Germain Act also protects transfers into a trust where the borrower remains a beneficiary, so moving the home into a revocable living trust will not trigger your mortgage’s due-on-sale clause.2Office of the Law Revision Counsel. 12 US Code 1701j-3 – Preemption of Due-on-Sale Prohibitions
Leaving the Home Through Your Will
If your goal is simply that your son ends up with the house after you die, naming him as the beneficiary of the property in your will is the most direct route. He receives the stepped-up basis, the home stays entirely yours during your lifetime, and none of the creditor or Medicaid risks apply. The downside is probate, which takes time and involves court fees. For most families that cost is much smaller than the capital gains tax your son would face from receiving the property as a lifetime gift.
When Adding Your Son Directly Still Makes Sense
There are situations where recording a deed and adding him as a co-owner now is the right call. If he is contributing to the mortgage, paying for major renovations, or living in the home as his primary residence, co-ownership reflects what is actually happening. It can also make sense if the home has not appreciated much since you bought it, which shrinks the gap between gifting and inheriting. And if you live in a state with a slow or expensive probate process and transfer on death deeds are not available, joint tenancy with right of survivorship avoids probate entirely.
Match the method to the goal. If the goal is that your son should get this house when you die, one of the alternatives almost always produces a better tax result. If the goal is that he should co-own it right now, prepare the deed, notify the lender, record it, and update your insurance and estate documents to match.
