my dad died in florida and owned 2 houses my stepmother claimed homestead on the one he lived in , is she entitled to any of the 2nd home ?

if your stepmother was legally married to your father at the time of his death, she has certain spousal rights. The fact that they were estranged will not abrogate those rights. Your stepmother has certain rights to the "Homestead" real property. There can only be one Homestead. In addition, your stepmother has a right to the elective share. There are also some smaller and less significant rights she may have by virtue of the marriage. You should speak with a probate attorney in your area.
