Legal Question in Wills and Trusts in Michigan

Re: placing a lien (property)

Typically you cannot simply lien the property of someone who owes you money without a judgment (unless you have an agreement or are a construction contractor). The state and IRS can also lien property, generally for taxes.

If the monies are truly owed to you (or the heir), then you can obtain a judgment lien (after filing suit). You have a variety options to enforce this judgment lien - including garnishment and property repo. While your question is vague on details, my best guess is that you will first need a court order to collect whatever money is owed.
