We are a Crime Scene Trauma Scene company; we provided services on a home in Port St. Lucie, Florida. The clean-up was completed and per our signed service agreement we processed the invoice through the (deceased) homeowner's insurance. The estranged husband was automatically listed as the next (per the insurance company) of kin and became the executor of the estate. He is the person that signed our service agreement. The insurance company issued a payment for our services in the form of a check and listed it as "IN THE ESTATE OF ______________". We were led to believe that the Executor (estranged husband) was in the process of setting things up with the estate lawyer and would have the estate (lawyer) pay our company for the services we provided. We have just learned that the executor (estranged husband) has just gone to the county to change the deed of the home into his personal name, and we have yet to receive payment for the services we provided. We want to place a lien on the home for our services. Is it possible to place a lien, is it possible to place a lien on the estate of the deceased, and on the Estranged husband?
