Adding someone to your home's deed seems straightforward, but it carries serious legal and financial consequences you must understand before signing.

Changing property ownership through a deed transfer triggers a chain reaction across your finances. Your mortgage lender may invoke the "due-on-sale clause," which allows them to demand immediate full repayment if ownership changes hands. Check your loan documents first. Some lenders enforce this aggressively; others don't. Either way, your lender has the right to know about the transfer.

Gift taxes enter the picture when you add a spouse, child, or other relative. The IRS allows you to give up to $18,000 per person annually (2024) without filing a gift tax return. Transfers exceeding this amount require Form 709, though you likely won't owe actual taxes unless your lifetime gifts exceed $13.61 million. Still, the paperwork matters for records.

California's Prop 13 offers exceptions for transfers between spouses or parents and children, but other states apply assessments immediately. Contact your county assessor before transferring the deed.
