ALTA - Real Property Surveys

This survey provides everything that an As-built survey does, but also addresses the title commitment of the property. The major difference between this and an as-built survey is the location of easements and other schedule B items that show up in the title commitment.
An ALTA survey is usually only required if the property is being sold, purchased or re-financed. The acronym stands for American Land Title Association and American Congress on Surveying and Mapping. These bodies have outlined the requirements and also provide additional options (Table "A") for these type of surveys.
