Two Sisters Have Owned Their Mother’s House Together Since 2014, and the Younger One Still Lives in It. When the Older One Needed a Nursing Home This Year, Medicaid Let Her Sign Her Half Over, and the Five-Year Look-Back Never Applied

If you co-own a house with a brother or sister who lives in it, you may already have one of the few home transfers that federal Medicaid law leaves alone. Under the Medicaid sibling exemption, you can sign your share of the home over to that sibling when you need nursing-home care, and the five-year Medicaid look-back period never applies to the transfer. No penalty months attach to it.

That headline describes this exact setup, as two sisters have been on the transfer since 2014, and the younger one lives in the house. This year, the older sister needed a nursing home, so she deeded her half to her younger sister and applied for Medicaid, and the gift didn’t cost her any coverage.

How Half a House Escapes the Look-Back

When you apply for nursing-home coverage, Medicaid reviews every transfer you made during the five-year (60-month) look-back period. Any gift inside that window triggers a penalty period, a stretch of months when Medicaid won’t pay for your nursing-home care. The home has a short list of exceptions, and a co-owning sibling is one of them. Two facts must line up: your sibling already owns part of the home, and your sibling lived there for at least a year before you entered the facility.

Where Congress Wrote It Down

The exemption sits in 42 U.S.C. § 1396p(c)(2)(A), the federal Medicaid statute on asset transfers. It protects a transfer of the home to “a sibling of such individual (who has an equity interest in such home and who was residing in such individual’s home for a period of at least one year” immediately before the individual is institutionalized. A related clause, § 1396p(a)(2)(C), also bars a state from placing a lien on the home while that sibling legally lives there. Each state runs its own Medicaid program on top of this federal rule. New York, for example, mirrors it in its Medicaid guidance.

Who Qualifies and Who Gets Shut Out

Here’s how you qualify: three things have to be true. First, the person receiving your share is your brother or sister. Second, that sibling already held a real ownership interest in the home before the transfer. Third, that sibling lived here continuously for at least one year right before you entered the facility. The clearest proof of ownership is having the sibling on the deed.

A sibling who moved in recently, moved out before your admission, or was added to the title at the last minute fails the test. This clause offers no protection to nieces, nephews, cousins, or friends. Adult children fall under a separate caregiver-child rule, which requires two years of living in the home and providing care that kept the parent out of a facility.

Six Steps to Sign Your Share Over Cleanly

1. Pull the recorded deed and confirm your sibling’s name is on the title. The equity interest has to exist before the transfer that relies on the exemption.
2. Put together 12 months of residency proof for your sibling: driver’s license, voter registration, tax returns, utility bills, and bank statements tied to the property.
3. Get your admission date in writing from the facility. The one-year residency time counts back from that date.
4. Have an elder-law attorney draft and record the deed that transfers your share.
5. List the transfer on your Medicaid application and claim the sibling exemption, attaching your documentation.
6. File a federal gift tax return (Form 709) if your share is worth more than the 2026 annual exclusion of $19,000 per recipient. In most cases, you owe nothing, because the excess counts against your lifetime exemption.

Traps That Can Cost Your Sibling Later

The residency test trips up the most families. Your sibling needs to live there for the full year before your admission, and states also check that the property is the applicant’s primary residence. If only the younger sister lives in the house, as the headline suggests, the state may ask whether it ever counted as the older sister’s home. Answer that question before anyone records a deed.

The gift also comes with a tax cost. Your sibling takes on your original cost basis in that half under 26 U.S.C. § 1015(a). If your sibling inherited your half instead, that half would generally get a stepped-up basis at your death under § 1014, wiping out the gain that built up while you owned it. Giving your half away gives up that step-up, so a later sale could mean a bigger capital gains bill for your sibling. Keeping your half has its own cost: states must seek estate recovery of nursing-facility costs from Medicaid recipients who were 55 or older.

Home equity rules are shifting too. For 2026, the federal limit is $752,000, and states can raise it as high as $1,130,000. Starting in 2028, H.R. 1 puts a hard ceiling of $1 million on home equity for Medicaid nursing-home coverage, so no state can go above that. If you co-own a home with a sibling, expect your state’s Medicaid office to want proof. That typically means a recorded deed and records showing your sibling lived there for the full year.
