(a) If a museum receives a written claim of ownership for any property for which notice of donation or abandonment was made, pursuant to § 11-84, from the lender, or the designated agent of the lender, the museum shall return such property to the lender or carry out the disposition of such property as the lender requests not later than sixty days after receipt of such written claim of ownership. The lender shall advise the museum in writing as to the disposition of such property or how such property is to be returned to the lender. Any costs incurred as a result of returning such property or the disposition of such property shall be the responsibility of the lender unless the lender and the museum have mutually agreed to alternate arrangements.

(b) If a museum receives a written claim of ownership for any property for which notice of donation or abandonment was made, pursuant to § 11-84, from a person other than the lender on record with the museum, the museum shall, not later than sixty days after receipt of such written claim of ownership, determine if such ownership claim is valid. A claimant shall submit proof of ownership to the museum with such written claim of ownership. If more than one person submits a written claim of ownership, the museum may delay its determination of ownership until the competing claims are resolved by agreement or legal action. If the museum determines that such written claim of ownership is valid or if the competing claims are resolved by agreement or judicial action, the museum shall return the property to the claimant submitting the valid claim of ownership or dispose of the property as such valid claimant requests. Any costs incurred as a result of returning such property or the disposition of such property shall be the responsibility of the valid claimant unless such valid claimant and the museum have mutually agreed to alternate arrangements.

(c) If no written claim of ownership is presented to the museum on or before sixty days after the publication of the second notice, such property shall be deemed donated or abandoned and title to the property shall vest in the museum. If a valid claim of ownership for such property is made after title to such property has vested in the museum under this subsection and the museum holds title to such property, then the museum shall return such property to the owner of such property and the title of such property shall revert back to such owner.

(d) Any person who purchases or otherwise acquires property from a museum that obtained such property by donation or abandonment pursuant to this section and sections 11-81 and 11-82 shall acquire good title to such property.
