Legal Question in Elder Law in California

There is no Medicare reimbursement claim against your mother's assets upon her death.

If she dies owning the property, or a portion of it, then her interest in the property is subject to a Medi-Cal estate claim for benefits paid for your mother's nursing home care at any age or non-nursing home medical benefits after her 55th birthday.

However, the property can be sheltered by gifting it to you outright (usually a bad idea for tax reasons), or by transferring it to an irrevocable trust. My law firm does this sort of work. If you are interested, please contact me.
