Prob. Code, § 5677

(a) If proceedings for the administration of the transferor’s estate are commenced, a beneficiary of a revocable transfer on death deed is personally liable to the estate for a share of the transferor’s unsecured debts.

(b) In calculating the beneficiary’s share of liability under subdivision (a), the abatement rules provided in Part 4 (commencing with Section 21400) of Division 11 shall be applied, using all of the following assumptions:

(1) The property that was transferred to the beneficiary by revocable transfer on death deed shall be treated as if it were a specific gift made by the decedent’s will.

(2) The value of the property received by the beneficiary pursuant to the revocable transfer on death deed shall be deemed to be the fair market value of the property at the time of the transferor’s death, less the amount of any liens and encumbrances on the property at that time.

(3) Any unsecured debts of the transferor that were paid by the beneficiary pursuant to Section 5672 shall be treated as if they were claims made against the transferor’s estate.

(c) The personal representative shall provide a written statement of liability to the beneficiary, which specifies the amount that must be paid to the estate.

(d) The beneficiary is personally liable to the estate for the amount specified in the statement of liability. Any amount that the beneficiary paid toward the unsecured debts of the transferor pursuant to Section 5672 shall be credited against the amount that the beneficiary owes the estate under this subdivision. If the amount that the beneficiary paid pursuant to Section 5672 exceeds the amount specified in the written statement of liability, the estate shall reimburse the difference to the beneficiary. For the purposes of Section 11420, this reimbursement shall be deemed an expense of administration.

(e) In the event that the beneficiary and the personal representative cannot agree on the reimbursement or liability due under this section, the beneficiary or personal representative may petition the court for an order determining the amount of the reimbursement or liability.

(f) The reasonable cost of proceeding under this section shall be reimbursed as an extraordinary service under Sections 10801 and 10811. The beneficiary is liable for the payment of that cost, which shall be separately identified in the statement of liability.
