Who can sell my deceased father-in-law''s property?

You have several options.  Someone can go to the local clerk's office, probate department, and qualify as an administrator of the estate, and then sell the assets and use them to pay the debts.  The second option is that you or your husband could send bills for storage of the items, and then when the bills are not paid, sell them to satisfy the bills, up to a limited amount.  Both options have fairly technical requirements, so you will want to consult with an attorney in your area to ensure you follow the correct procedure so that you can sell the items without exposing yourself to claims from others.   This answer is given in accordance with the laws of Virginia, and is based on the facts that are recited, and assumptions which may or may not be accurate. Accordingly, this response may not be relied upon and may not be applicable in any other state. It should not be relied on as legal advice, as that would require a detailed analysis of all of the facts involved in a specific case, not just the limited facts presented in the question.
