We are in the same situation you are now. If the property is a conjugal property, half of it should have been liquidated to the 4 daughters and surviving wife through either an Extrajudicial Settlement of the Estate or Judicial Settlement of Estate. Actually if it is indeed a conjugal property, half of the property already belonged to the 4 daughters, and the other half no heir can demand an inheritance or right over it because the wife is still alive. Only then the 4 legal daughters/heirs can have inheritance over it. This is what happened to us. It was too our problem when my mother went with the Lord 13 years ago, and is still a problem, now that my father passed away recently leaving us problems with taxes, documentations, etc. Why not try to go to www.familymatters.gov.org. I did and was a great help!
