(2)Disposition of tangible personal property (a)1. A reference in a will to another document that lists tangible personal property not otherwise specifically disposed of in the will disposes of that property if the other document describes the property and the distributees with reasonable certainty and is signed and dated by the decedent.The court may enforce a document that is not dated but that fulfills all of the other requirements under this paragraph.

(am) Another document under par. (a) is valid if it was signed in compliance with s. 853.03(1) or with the law of the place where the document was signed, or where the testator resided, was domiciled, or was a national at the time the document was signed or at the time of death, even if it was not otherwise executed in compliance with s. 853.03(2) or 853.05.

If a valid document is located after some or all of the tangible personal property has been disposed of, the document controls the distribution of the property described in it, but the personal representative incurs no liability for the prior distribution or sale of the property, as long as the time specified in this paragraph has elapsed.
